  1. It might be useful!! How to add google maps into ArcMap Although ArcGIS allows to bring the Bing maps and Esri images as base layers in ArcMap, still sometimes we rely on google images because of their better accuracy and their frequent update. Some of us using openlayers plugin in QGIS to access the google maps as a base map. This tutorial shows you to how quickly you can add the google maps, google hybrid images and open street maps etc. to the ArcMap for testing purposes. Portable basemap server PBS is an open source WPF application which can be used to access the WMTS basemap service inside ArcGIS. Steps 1. Download and unzip the file in the desired location of your PC.(download link). 2.Open the Portable Basemap Server folder and right click thePortableBasemapServer.exe 3.Select the GoogleMapsImagery or desired one in the Data Source Type drop down menu. 4. Then click the Start New Service button. 5.Copy the OGC WMTS URL by clicking the Copy to Clipboard. Don't stop the PBSapplication, just minimize that. 6. Next open the Arcmap. 7.Open the Catalog and then click the Add WMTS server in GIS Servers. 8.Paste the Copied URL here in URL text box. Click Get Layers and click OK. 9.Next, right click the added WMTS Server and click the connect option. 10.Now it’s time to import the base map layer. You can drag down theGoogleMapsImagery from the Catalog to ArcMap Data View or you can simply add through the Add Data option.
  2. Hi all I recently renew my Laptop with a better one with windows 10 platform, but I have a problem with some software such as arcgis 10.2.2 In the software environment, icons are really small. when I change arcmap setting to big icons, the size of icons getting bigger than normal condition in the past! please help me. I like normal view of arcmap.
  3. Hello to all. Have a problem with creting html popup with Carrymap in ArcGIS. Images appears too big for popup. Script for image insert: <% var tag = '<img src="'; tag += CF.Values["img"] + ".JPG"; tag += '">'; echo (tag); %> Could I change image size in pixels or percents in script?
  4. I am attempting to downscale a plethora of temperatures points over a high resolution DEM, and have hit several roadblocks. On further research, I have found a method in which to execute this task, but am stuck on how to execute within ArcMap. The weighted linear function I plan to use is as follows `y=Bx+C` Where y=predicted temperature, B and C are coefficients, and x is the DEM layer. There are also several complex weighted functions that determine the influence of the station on the regression model as the specific DEM cell gains altitude away from the station and proximity away from the coastline. I've also attached the thesis in which this mirrors, which goes more in depth on the equations in question. Any help would be great, thank you! Eric
  5. Hi everyone, does anyone knows how to generate a digital surface model with some satellite imagery? it's possible to create a terrain from stereo imagery in ArcGIS? and with just f.ex. 3-5 images not stereo? References :
  6. Yet another article explaining all the details one should remember for faster ArcGIS workflow. Check this out..... When it comes to computer hardware, there is a lot you can do to increase the performance of ArcGIS. The decisions you make about processor, disk, memory, etc. are all critical issues that can often be overlooked – even by the experts. The following is a listing (in order of importance) of some key hardware issues for ArcGIS – specifically for Geoprocessing tasks in ESRI ArcGIS products like ArcMap and the ‘arcpy’ Python module. Let’s get started: Processor: Without a doubt, this is the most critical consideration. Having a modern processor with the fastest clock speed you can afford is by far the most significant performance choice you can make. Right now in Q1 2013, my quick recommendation is (for a Desktop system) the Intel Core i7 3970x, and (for a Workstation/Server system) the Intel Xeon E5-2687w. Price aside, there are some key considerations that you need to know about when deciding what processor you should buy: Chip architecture: This basically describes the techniques used to design and construct the processor. As you might imagine, processor architecture is an extremely complex and constantly evolving field. If you have a strong cup of coffee, 10 minutes or so, and enjoy melodrama. Generally speaking you want to be sure to always buy the most modern (but mature) chip architecture that is on the market, but also at the same time ensure that the chip has a high clock speed (see below). Sometimes it takes the chip manufacturers a while to release the high clock speed models when the release a new processor architecture. This effect is described in the Intel “tick-tock” model. In any case, you should probably wait until the “tock” happens lest you end up with a processor that is actually a bit slower than the higher clock speed version (see the next section) of last years processor family. It is very important to note that chip architectures vary considerably, and it is unwise to make straight across comparisons of processors with different architectures. For example, a 2.8 Ghz processor model from a few years ago will invariably be slower than a 2.8 Ghz processor of today. Main point here: Unless there is a compelling reason, don’t buy yesterdays processor architecture. Clock speed: This is critical. The clock speed is a measure of the processor “frequency”, which basically refers to how fast the electrons cycle through the processor… Similar to someone flipping a light switch on and off really (really) fast. With each on/off cycle, the processor “computes” something. Generally speaking, you want to buy a processor with the fastest clock speed you can afford. Of course increased clock speed (aka processor performance) does come at a price: Not only do high clock speed chips cost more initially to purchase, they also require more electricity to both power the processor and to properly cool it. This is why many large IT shops (think large server rooms and data centers) do not generally buy the highest clock speed processors… doing so increases their electricity/cooling demands. Is performance or energy efficiency more important? I will leave that up to you to decide. Number of cores: The argument of “more is better” sounds logical here, but in truth it really depends on your intended use. Generally, the more cores a processor has the slower the clock speed (otherwise all those cores would get too hot). That said, having more cores theoretically allows you to run more processes at the same time without having them compete for limited processor resources. However, all good ESRI GIS users should know by now that ArcGIS is a single threaded application – at least for now – meaning that a single instance of ArcMap will only use the equivalent resources of a single processor. For example, lets suppose you have a 4 core processor, and are running a single instance of the Clip tool. In that case, you will only be using 25% of the total system processor resources. Having lots of processor cores only makes sense if you can effectively take advantage of them. A good example where extra cores does make sense is if your hardware will be used by many people at the same time (think Citrix, Remote Desktop Protocol, Virtual Server (Hyper-V), etc.). Another use case where lots of cores make sense is if you are an intensive multi-tasker (you are running Excel, ArcMap, Python, Access, etc. all at the same time) and/or you are a decent programmer and can write scripts to run your large GIS processes as separate processes – for example using the Python ‘subprocess’ or ‘multiprocessing’ modules. Unless you fit one of these use cases I would recommend you go with a processor that has fewer cores but higher clock speed. Something good to know also: Most decent processors these days have at least two cores, and with something called multithreaded architecture (Intel calls it ‘Hyperthreading’), the number of cores is effectively doubled. This is why your two core Intel i5 processor appears to have four cores. What’s the optimum ratio of cores/clock speed? Again, I will leave that up to you to decide. My general recommendation: Clock speed first, cores second. When comparing clock speed, make sure you are using the same/similar chip architectures to base the comparison on. Cache: A processor cache is basically a type of very fast memory buffer that physically exists exists inside processor. The idea being that it is much faster to read from the processor cache than the RAM, and so it stands to reason that it if you load up the cache with data from the RAM that have a high probability of being used, the data will be more readily available and thus reduce latency. A decent sized processor cache today is typically more than 10MB or so. Having a larger cache will generally make the processor more efficient and fast. How much so depends on your data and algorithm structures. Memory (aka Random Access Memory – RAM): Think of computer memory (aka RAM) as an intermediate, temporary, and fast storage area between the disc and the processor. In a way, RAM is a smaller and faster version of a disk – with no moving parts. The more data you can read and write to/from the RAM (instead of the disk) the faster your process will be. How much memory you need depends a lot on how you process data and the type of data your process. My quick recommendation is to buy at least 2GB of RAM per processor core (possibly less if you have lots of cores). Consider 3-4 GB or more if the machine is going to support many concurrent users and/or very large GIS processes or GIS ‘power users’. One benefit to having lots of RAM available is that it provides a higher limit to how large the ESRI ‘in_memory’ workspace can hold. For users that don’t know, the ‘in_memory’ workspace is a type of RAM disk that can be used to temporarily store tables, feature classes, and now in v10.1, raster datasets as well. In addition, more memory means that you can process larger datasets using memory intensive tools such as Dissolve and Union. Up until a few years ago, it used to be that a single instance of ArcGIS physically couldn’t use more than 2.1 GB of RAM due to it’s status of being compiled as a 32-bit software… And actually the limit was in effect more like 1.4 GB or so due to system overhead. However a few years back, ArcGIS users were able to take advantage of more RAM using a secret ‘Large Address Aware’ setting. If you have this turned on, and had a 64 bit operating system, you can theoretically use up to 4 GB of RAM. Now with ArcGIS 10.1 the ‘Large Address Aware’ setting appears to be turned on by default, and for v10.1 Service Pack 1, the install package includes a new ’64-bit Background Geoprocessing’ installer, which theoretically allows background geoprocessing tasks to (basically) use as much memory as your system has. Similar to a processor, memory also has an operating frequency (for example, 1600 Mhz), and generally the faster the frequency, the faster the memory can communicate with the processor. Be sure that your processor is compatible with the memory you are purchasing. Also, be sure you are buying the latest memory type which is DDR3 (double data rate type 3). Note that DDR4 memory is on the horizon and will be better/faster than DDR3. My final say on RAM: Since lots of RAM can be expensive, don’t buy a whole bunch unless you know how to effectively use it – and if you do – well then 64 GB of RAM (or more!) wouldn’t be unreasonable. That said, sticking to the 2GB of RAM per processor core rule should be sufficient for the majority of single user ArcGIS applications. Consider more for multi-user systems and/or expert ArcGIS ‘power-users’. Disk: The two largest considerations about disks are their capacity (how much they can store), and their speed (how fast can they transfer data to and from the RAM and processor. Historically, disks have had spinning magnetic platters, but in the last few years Solid State Drives (SSDs) have become increasing popular. SSD have no moving parts and are extremely fast… In some cases, approaching the speed of RAM. In fact, SSDs resemble RAM much more than a conventional magnetic disk drive with a spinning platter. If you have noticed something by reading my post up until this point, it is that the dividing lines between the disk, RAM, and processor is being blurred, and it may not be too long until it is blurred even more… perhaps to the point that someday they become a single integrated piece of hardware… Well maybe. So SSDs do have disadvatages: One significant issue is price: They are relatively expensive, and the other is capacity: They don’t have nearly as much storage capacity as magnetic platter disks (for example, you effectively can’t buy a 2TB SSD drive). My quick recommendation is, if you can afford it, buy a modern large capacity SSD (6.0 Gb/s or more and ~ 500 GB which will cost you about $500 as of Jan 2013). In my opinion, their speed is worth the extra price… If you are frustrated by how long it takes for ArcMap to start up, you will be amazed to see that a fast SSD drive will bring ArcMap start time to a few seconds or less. SSD performance really shines when running parallel tasks/processes – their throughput is quite remarkable. Magnetic disks are still the dominant disk type by far… but probably not for long. As a ‘hybrid’ approach, It is possible to have both SSDs and conventional HHDs in the same computer, thereby having the best of both worlds. Another option for advanced applications is configuring your disks (you will need at least two) in a RAID array. RAID can significantly increase speed, capacity, and reliability of your disks, but it will be at least twice as expensive as a non-RAID set up. Final recommendation: Be sure to buy enough storage capacity for your needs right now, and then multiply by three. GIS datasets aren’t getting any smaller, in fact quite the opposite! Also, although SSDs remain orders of magnitude more expensive than conventional HHDs, they are worth it, especially for data intensive applications like GIS. Video card: Video cards (aka graphics cards) increase the performance of graphical display to you monitor. For example a nice video card will make, a 3D rendering of ArcScene or ArcGlobe more smooth and fluid. Personally, I don’t do a lot of 3D rendering so I may be a bit biased here. High end video cards are more geared towards computer animators and computer gamers. If you don’t do that, then you probably don’t need a high end graphics card… A 256 MB one will do you just fine. However, one emerging technology to take note of is something called GPU processing, which basically allows you to take advantage of the Graphics Processing Unit (GPU) in a video card and use it for general processing tasks unrelated to graphics display. A GPU (as opposed to a CPU) has the advantage of having hundreds or sometimes thousands of processing cores, and the idea being to make processes massively parallel so that each core in the GPU can work on a small piece of the larger pie. Is this an easy to do? The answer is a resounding ’No’. Algorithms need to be rewritten at a very low level to take advantage of GPU computing, and that is very labor intensive. Note that ArcGIS at this time (Jan 2013) does not support GPU computing, but ESRI has hinted that it may in the near future. Here’s a great article all about it. So with that, having a GPU/CUDA worthy video card will probably be something that you should consider in the near future. Right now, maybe not so much. Video cards are very easy to install, so it might be an upgrade to consider if ESRI gets GPU computing usable in ArcGIS. Thanks for reading!
  7. Dear Para Master GIS & RS, Ada yang tau kah cara (script python atau modeler atau mungkin udah ada di toolbox) yang bisa save / export simbologi hasil klasifikasi nilai di atribut ke field baru? Mohon pencerahan dan ilmunya, hehe Terima kasih
  8. Greetings, Please forgive me if my english is not true. I want to ask something fundamental about the register map with ARCGIS. I have a shp file that has been registered, this time I want to change the register early because they did not fit. What should I do it again from scratch, or there may be a way to change it directly to the shp fil? Please provide fill to me about this issue. Thank you
  9. Salam kenal para master GIS Indonesia, Saya baru mulai belajar mengenai GIS, jadi pasti memiliki banyak pertanyaan. Masalah saya yang pertama ini adalah saya memiliki file dalam bentuk .shp yang telah diregister pastinya. Sekarang saya ingin merubah register yang ada di file .shp tersebut. Mungkinkah ada cara untuk merubah registernya tanpa harus mengulang dari awal lagi?bagaimana caranya jika ada?Mohon para master bisa memandu saya menyelesaikan masalah ini. Terima Kasih.
  10. This is a tricky one. A little context first: Bentiu wiki page: + OSM map of Bentiu refugee camp, South Sudan: My task is to come up with a map of the dwellings and the facilities in the camp, each with their corresponding address. For this I have (1) a schematic grid of the address system (.pdf), (2) indications on how the address system works (start numbering the buildings from the NW corner to W then S), and (3) the .shp of the individual houses and buildings extracted from aerial imagery analysis. Problems: (a) while the grid assumes that buildings are perfectly-aligned squares, the shp shows different shapes of dwellings that partially follow the spatial organisation set up for the address system; ( the drawing and the numbering are currently being used for healthcare provision and cannot be modified to fit the structure of the dwellings. So far I have tried a couple of tricks unsuccessfully, mainly because the drawing is only a representation therefore cannot be georeferenced. I tried to assign every house in the .shp a number with $rownum but this did not work either because the order was not respected. I'm more than willing to discuss any ideas!

  12. down votefavorite i have a problem whem i am working to calculate the ndvi from landsat sattellite of rainy season i have assumed the pixel value above 15000 are clouds and calculate NDVI.then i am assigning the clouds pixel in ndvi 1. The main question is how to calculate zonal min max value of ndvi and percentage of cloud and percentage of ndvi greater than 0.5 in a particular zone.(zone are the vilage boundary of District). please help to solve this problem in arc gis.
  13. Hello everyone, I am working on risk. I have used an heuristic aproach and i've generated a susceptibility map of risk and i want to validate my map by comparing with the inventoried traininig sites. does anyone know how to use the (SCAI) seed cell area index or any other alternative? Thanks
  14. I have a multi-temporal NDVI package of raster images (100) and each image represents the monthly-annualy values of the NDVI for a large geographic region (28 april 2000, 15 may 2000, 24 july 2001, ...etc). I would like to export the rasters to an Excell table that should contain: date of image aquisition, a specific geographic region and the NDVI values for that region of interest. The values should be averages, minimum and maximums. With this table, I would like to make some statistical analysis. So, how can I do this job, by using ArcGIS or any other software ? Thank you. Arhanghelul
  15. Hello and I am almost finished completing a GIS application using Geocortex Essentials with the silverlight viewer template and have a couple of questions for anyone who is experienced. 1. When creating a Feature Description my photos will not show up. I've had my photos in a virtual directory for a previous flex application we've ran for a couple of years now and have had no issues. In fact, when putting in a simple request such as <img src> in the editor but not in the mapping application (just the html code does). The Geocortex manual explicitly states that feature descriptions support images. 2. Simple ole db connections that were working the previous day tend to disappear with a server reboot or the following day. Very strange. The connections are all 100% correct and have been verified numerous times. I am hosting the database files so permissions and locations haven't changed. If anyone can shed some light on some potential fixes that would be great!

  18. How to remove unwanted background color we get in hydrology > direction and accumulation process .... i tried to make the background color to no color but its not working is the link of my snapshot to understand better
  19. Hello everyone, I install ARCGIS 10.2 and when I active the licence I got an error message about the presence of former version. I uninstalled all the previous version and all the app related however it still appears. Any ideas? Thanks RB
  20. I want to buy ArcGIS 10.2 products... I really do. But I just can't bring myself to march to the bosses office and explain why we need this release because the fact is we don't. ESRI has managed to take a product with hardly any changes of significance and roll into a new version instead of an update. Instead of focusing on the multitude of problems that have plagued 10.1 throughout its lifecycle, they've decided to not fix the product and build on it even more. They haven't addressed (among other things): The 1000's of bugs and errors that crop up all the time. I have keep error journals so I know what to do next time something happens because the ESRI help is usually pretty vague or doesn't work. ESRI support? I am my own "ESRI Support". Outdated and clunky interface. Mediocre KML/KMZ support compared to other geospatial software. Better CAD support within ArcMap (it's poor to average at best still) Better production quality maps (i.e. not having to resort to Illustrator for most of the work). Poor GPS support. Although GPX is a standard, what about the other multitudes of formats that are used? Its clear that although ArcGIS bills itself as a one-stop solution for GIS needs, it isn't. The bottom line is that most people still need another "go-to" program that will do the things that ArcGIS fails to do. Want better KML/KMZ support... gotta use GlobalMapper (or something equivalent). Geoprocessing task failing all the time.... gotta use QGIS (or something equivalent). Want a nicer looking map because ESRI's production quality sucks... gotta use Illustrator. GPS files not being handled properly... gotta go convert it in another software and then bring into Arc... wait a minute... might as well use GlobalMapper again. ESRI is supposedly the Mercedes-Benz of GIS software... so why is it driving like a mini-van? More and more I find myself thinking "I might as well use (x) program because ArcGIS will just be a hassle...". I've been an ESRI user since ArcGIS 3.2 and I still remember those days fondly. The days when you had to save your work every minute because a dreaded Dr. Watson error might crop up... Not much has changed except that there are now more errors. Its almost like the presence of ESRI online-help is an excuse to have all these errors in their software. Someone needs to tell ESRI that sometimes less is more. That's my rant for the day. Thank you to anyone who chose to read it and I'm sorry if it was long-winded. Just don't get me started on ArcGIS Server or ArcPad software... holy crap... I need a panic room!
  21. I heard the new ArcGIS online subscription provides easy tools to create a web page embedded with maps , with minimum Programming knowledge. We can embed maps in the existing websites such as this one Or share our maps in social networks like facebook. I suggest our members make use of the one month trial subscription offered by AGOL. Happy webmapping !!
  22. Dear All, I wanna share my concern about creating the application in flex. I wanna create the application of sea routing, then I utilize network analyst; the closest facility and new route facility. While creating the application for new route there is no problem appeared. Flex application to find the new route with the input data can works as well. But the problem is appeared when execute the closest facility, I already used the default parameter in ArcGIS 10.1, but It doesn't work. The parameters are same as the default but, in my application can not input the point as the facility and incident. the alert is --> No "facilities" found for "My Location" in "Incident" No Solution Found. Then I check the way I publish the network analyst from arcGIS 10.1, and the parameter as the input in Flex there are no mistakes, but the application to create route still doesn't work. I really appreciate for the responses. Thanks regards isti

  24. At the moment I am using Global Mapper + a custom fishnet in order to export (download) orthos from a WMS Server. I just select the polygons and exporting them in GeoTIFF. I was wondering if there is a similar process that I can use in ArcGIS 9+ 10+, in order to do the same thing? If anyone knows how to do it, please let me know!
  25. Hello, I wanted to know if it is in any way possible to snap two features from two different layers toghether? Thank you, Paul
