  1. I need to develop a web page showing terrain that can be accomplished using cesium. A user may upload a shapefile/KML or select an area from Map. Once a shape/feature (polygon) is added to the map, how can it be used to extract 3D terrain model encompassing the defined polygon in any of the 3D model formats like obj? The extracted model is then to be displayed on the web page that can be done via three.js probably. So here are my questions. 1. How can I extract a 3D terrain model in cesium (or any other platform) as per defined area? 2. How can that model be displayed on the webpage at runtime? I have programming experience in leaflet, R Shiny, Python etc. but I am quite new to 3D modelling. I have been searching the web for days but couldn't find anyway to accomplish the task. Any hint on how to proceed, guidelines or tutorial would be highly appreciated.
  2. Greetings every one! I have a question to ask. I have high resolution satellite imagery of my study area/AOI. I also have geotagged photo spheres of some streets in the study area. I want to develop a web page showing my satellite imagery and on demand Street view of the 360o panoramic pictures I have. Web page is to be viewed on LAN with no internet access. I can use open layers and overlay streetview from google but I want to do the same with my own satellite imagery and photographs. I need your advise from where to start. If possible, I want to use Autodesk Infrastructure Map Server or mapguide maestro. Any prompt help/suggestions would be much appreciated. Regards

    Just install the software. Make sure you are installing version 8.7. When it asks for license during installation, check "set licensing parameters later". After installation, apply medicine. It should work.
  4. Yeah I've checked already. The same script works fine on ArcGIS 10. So this is 10.1's bug afterall???
  5. Hi, Tabulate area or Zonal Statistics as Table end with [000000_12301899] error when running from ArcToolBox. Using/calling them in python such as arcpy.sa.TabulateArea.... results in a simple crash. no warning. I've tried all possible workarounds. Changing pixel size, using feature class/shapefile as zone data etc. etc. Sometimes tool runs fine and sometime it gives the error (with exactly the same parameters). Crashes ArcGIS each time when called, in python. Is it the new version's problem??? I am using ArcGIS 10.1 with SP1.
  6. Problem connecting Mapguide to SQL server 2008

    I was having some other problems with IIS and AIMS so I had to not only uninstall AIMS but also clean install windows, IIS, Visual studio, SQL server and AIMS. I created a new login in SQL server with full privilidges and then connected AIMS studio using above mentioned method. This time it worked. So some1 having same problem should see if everything in AIMS and IIS is working fine and use a user account with full permissions in SQL server. Regards
  7. Hi, I am having problem connecting my Autodesk Infrastructure Map Server (AIMS) studio with MS SQL Server 2008. I've created a "New Feature Source" by clicking on New>Data Connection. I've pointed out the desired database in "Data Store" and tested the connection which is OK. I then saved this FeatureSource in the library. Now when I create a new layer and open the saved data source as the layer's data source, it doesn't show any featureclass/table that the database in "Data Store" actually holds... What I am doing wrong here? The database holds two (spatial) tables; roads and homes. Any help will be much appreciated!!!!
  8. Web Server suggestions!!!

    @ arcsump Yes I need to serve spatial data. And I now have to work on mapguide. I have to link sql server 2008 with mapguide. Ultimately, I'll have to use autodesk mapguide but for initial stage, can anybody give me some tips/tutorial on how to link sql server with mapguide (autodesk or open source). Thanks in advance

    Thanks for the link lurker
  10. cloud removal from landsat mss image

    I agree with rahmansunbeam plus developers have developed some temporal filtering techniques using Matlab or R etc. that process an image pixel by pixel and replace a cloud pixel with a suitable land value by looking into next and previous available images. I don't have any such script right now to provide but I have heard about a PhD thesis in which more or less same thing was done on some other satellite may be. So if you can do image processing using programming then you can search for that thesis.
  11. Web Server suggestions!!!

    I need to opt for a solution immediately and start working on it. Hosting prices for sites developed using javascript API's like google maps are far less than the mapping servers. So why should I opt for an expensive option (in terms of hosting prices) over the javascript API's considering the above mentioned requirements. Any help would be much appreciated. Regards
  12. The original poster didn't come back to the topic but I think he clipped some raster and converted the clipped raster to a polygon shapefile. He wants count column from clipped raster to be displayed in polygon shapefile may be. He can also use JOIN if that was his purpose.
  13. Web Server suggestions!!!

    Hi, I want to develop a website in which I want to show data that consists of 5-6 layers with 1-2 GB size. The data will be converted/saved in MS SQL server 2008. Some satellite image as a base layer may or may not be needed in later stage. Layers include point, line and polygon geometry types. Data will be queried by end user using combo boxes may be and queried data will be displayed on may be google maps or my satellite imagery or only the data alone. My problem is that I've only a little experience of google maps api. I don't know pro's and con's of using a map server like mapguide, mapserver, GeoMedia or ArcIMS etc. or google maps api. Can any body give me a comparison of capabilities of these webgis solutions considering above mentioned requirements. Regards

    You are welcome. Yes you can export into shapefile ofc. This is what medicine is for
