  1. Detecting plant disease by remote sensing

    I know one initiative who are doing similar project with Wageningen University. They have successfully done few similar work in Natherlands. This project is using Sentinel-2 image and combining that with local weather information to calculate late-blight disease vulnerability index. The project implements IDL and Python to automate the RS analysis. So far I know, this disease is highly dependent on moisture and temperature, and potato fields are relatively easy to identify from RS data. We are doing something similar, but for paddy. There might be some algorithms already which you need to research.
  2. Mutli criteria analysis using Arc Map

    There are no 'best option' for MCDM. Each method has their own pros and cons. Try with something simpler, ie. AHP.
  3. PGSQL Enterpise GDB connection error

    Update (7 Feb): Finally I requested to close the issue, after suggesting the solve to them (which was suppose to the other way around). I hope they note this issue carefully and flag this issue as a bug. I could have done this myself if I'd know how. I am also surprised they didn't immediately have a solution, pokes back and forth once in everyday after lunch (though they immediately asked me if I want to close this issue once I suggested the solve !!). Wish me luck...
  4. PGSQL Enterpise GDB connection error

    The ubuntu apt-get channel currently installs 9.5 version, which I already mentioned. I tried the PGSQL 9.4 as well, with the downloaded files from 'my esri', still no response. Should I try 9.3 as well? 9.3 is still supported (minimum requirement page) for 10.5.1 but not for the 10.6. Update (26 Jan): three days already passed since I asked for a fix and ESRI South Asia couldn't respond. Meanwhile I compiled the exact version of PGSQL (9.5.3) from source, still no luck. Update (31 Jan): They asked me for a teamviewer session which I happily participated. They said, they will 'recreate the linux version of this error and let me know'. I hope they have a linux expert in Singapore or send this to someone at USA. People in ESRI Southasia region - beware. Update (5 Feb): I can't believe they are still 'researching and looking for the solve'. By this time I installed Desktop 10.6 and able to solve this with same file from 10.6's folder. I am not saying anything to these 'engineers'.
  5. Did anyone face this error? I am repeatedly facing this while connecting ArcGIS Desktop to PostgreSQL. I installed the PostgreSQL with apt-get inside an Ubuntu vm. The vm also has Enterprise 10.5.1 installed and configured. The plan is to configure the Portal once this connection is done. I have already tried copying the ST_GEOMETRY file (*.so) for v9.5 (/usr/lib/postgresql/9.5/lib) but that didn't work. Also tried 9.4 and 9.6. Tried both desktop and server files.
  6. The upcoming features of QGIS 3

    Not yet. Probably take some time. Check this blog (2016) and the road map. more: Will QGIS 2.99 and QGIS 3.0 always be the same? Update: 23 Feb is the regular release, LTR coming in 23 June.
  7. The upcoming features of QGIS 3

    Check out the NorthRoadGeo demonstration of the newest features of the upcoming QGIS 3. There’s also a lot of behind-the-scenes changes which they haven’t touched, e.g. a switch to Python 3 and Qt 5 libraries, a brand new, rewritten QGIS server, new QGIS web client, enhanced metadata integration, GeoNode integration, HiDPI support, a cleaner, stabler, easier PyQGIS API, 1000s more unit tests, and so much more. Get the development from here. According to this blog QGIS 3 will take some time to launch, maybe a year or so. Since the project timeline cannot be directly ensured because developer force is largely volunteer based or work according to their own companies agendas, all we can do now is to wait and try the latest builds.
  8. Ubuntu 17.10 Breaks the BIOS on Some Lenovo Laptops

    Somehow I find both of this two thing a bit edgy. I have seen two very good looking Lenovo pc going down in just a year of light use. Though I've used W530 happily for myself for over 3 years, except for some graphics issues. I also stopped experimenting new releases of Ubutnu and settled with the LTS. Unlike many other brands Lenovo use to customize their own driver software to fit their machines. This is problematic for third party manufacturers (ie. Realtek) and even open communities to easily track any hardware issues. The best thing I think is to consult with the Lenovo requirement webpage of their pcs and stick with that. And marry xmas to everyone.
  9. Help with GIS and Applied Ecology

    The first thing (I think) should be to find the methodologies used for the maps you have, and the people who made them. If someone have already identified the spatial distribution, then your work should start on top of theirs. I have seen GPS-based tracking of wildlife (resident wild birds) to research their behavioral pattern. The research was possible because the particular species usually roam in groups/ herds, so we used small GPS trackers for one of them which sends coordinates in a remote server. The coordinates are later used to plot data over Google Map to see their feeding area.
  10. Myths and Misconceptions about remote sensing

    The links have changed over these years. Please consider this link.
  11. gis research

    Very generic question. Just like usual, there are not fixed rule. 'climate change' and 'population hazards' are likely to become a more of a political term (as it usually does, when we can't solve problems any more we start blaming others). These two terms are earning more for politicians now-a-days. We should get used to of this. a more recent and obvious field for researchers could be 'criminology' driven by 'social insecurity'. More and more people are becoming restless, domestic crimes are increasing, and a lot of policy makers don't know why. It could be a something in between 'behavioral' and 'natural science'. We haven't tried any technology for this field yet. with the rise of AI, big industries are replacing their labors with machines. The Asian countries already realize this and will soon start building their own skills. smartphone and tablet based decision support system are likely to see a new era. It is probably the fastest way to on-board a good number of people and communicate within different social and age-groups. I am currently working in a similar field and the scope is likely to widen in the coming days. with increasing number of hand-held devices, the pattern of internet use and communication has also chanced. Cloud-based data infrastructure and computing are getting popularity. JavaScript and HTML are building consumer brands - softwares and apps. Asynchronous data sharing and communication are getting part of our life, (ie. Twitter and Facebooks). This also leads to a new problem, fast transmission is spreading flawed and dangerous information. We haven't tried adding locational (in situ) information to justify them beforehand. there will be a good number of innovative Location Based Services in the coming days. AR and VR based technologies are likely to come out of the 'entertainment industries' soon. we already know that the number of free source satellite imageries will increase in the coming days. Open-source tools and libraries will become abundant, so does the opportunity to use these and build GIS-based tools which doesn't need expert hand. Almost all good universities of the world are currently studying GIS and RS. By the end of the next decade, almost all small and big organization will have at least one desk for their 'GIS analyst'.

  14. Intel announced a new family of “Core X” desktop processors at Computex yesterday, offering even more powerful versions of its existing Core i5 and Core i7 models, along with a new, top-of-the-line Core i9 line for those who want even more firepower. Last year at Computex, Intel unveiled its first 10-core consumer CPU, the company's move into the world of a "megatasking." It was a pricey chip, launching at around $1,700, but it satisfied users who needed to juggle several intensive tasks at once. Now, Intel is upping the ante with a new family of processors for enthusiasts, the Core X-series, and it's anchored by the company's first 18-core CPU, the i9-7980XE. Priced at $1,999, the 7980XE is clearly not a chip you'll see in an average desktop. Instead, it's more of a statement from Intel. It beats out AMD's 16-core Threadripper CPU, which was slated to be that company's most powerful consumer processor for 2017. And it gives Intel yet another way to satisfy the demands of power-hungry users who might want to do things like play games in 4K while broadcasting them in HD over Twitch. And, as if its massive core count wasn't enough, the i9-7980XE is also the first Intel consumer chip that packs in over a teraflop's worth of computing power. If 18 cores is a bit too rich for you, Intel also has other Core i9 Extreme Edition chips in 10-, 12-, 14- and 16-core variants. Perhaps the best news for hardware geeks: The 10 core i9-7900X will retail for $999, a significant discount from last year's version. All of the i9 chips feature base clock speeds of 3.3GHz, reaching up to 4.3GHz dual-core speeds with Turbo Boost 2.0 and 4.5GHz with Turbo Boost 3.0. And speaking of Turbo Boost 3.0, its performance has also been improved in the new Extreme Edition chips to increase both single and dual-core speeds. Rounding out the X-Series family are the quad-core i5-7640X and i7 models in 4-, 6- and 8-core models. While it might all seem like overkill, Intel says its Core i9 lineup was driven by the surprising demand for last year's 10-core chip. "Broadwell-E was kind of an experiment," an Intel spokesperson told Engadget. "It sold ... proving that our enthusiast community will go after the best of the best... Yes, we're adding higher core count, but we're also introducing lower core counts. Scalability on both ends are what we went after." As you can imagine, stuffing more cores into a processor leads to some significant heat issues. For that reason, Intel developed its own liquid cooling solution, which will work across these new chips, as well as some previous generations. All of the new Core i9 processors, along with the 6- and 8-core i7 chips, feature scorching hot 140W thermal design points (TDPs), the maximum amount of power that they'll draw. That's the same as last year's 10-core CPU, but it's still well above the 91W TDP from Intel's more affordable i7-7700K. Over the past few years, Intel's laptop chips have been far more interesting than its desktop CPUs. Partially, that's because the rise of ultraportables and convertible laptops have shifted its focus away from delivering as much computing power as possible, to offering a reasonable amount of processing power efficiently. The new Core i9 X-series processors might not be feasible for most consumers, but for the hardware geeks who treat their rigs like hot rods, they're a dream come true. Source - Engadget, The Verge
  15. Try Mapbox. Mapbox will let you build your map from scratch and manage the resources at your will. Mapbox is not free, for that you'll need something like Mapserver.
