    @spazzleThanks for the reply and for the links
  3. Linkage mapper

    Linkage Mapper is a GIS tool designed to support regional wildlife habitat connectivity analyses. It consists of several Python scripts, packaged as an ArcGIS toolbox, that automate mapping of wildlife habitat corridors. http://www.circuitscape.org/linkagemapper Forum https://groups.google.com/forum/#!forum/linkage-mapper
  4. I have a set of polygons showing core forests and also sets of lines showing the connections between core forests. Is it possible to link these polygons with the given lines using linkage mapper?
  5. Linkage mapper

    Hello all, Can anyone suggest where i could find details about "Linkage mapper". I tried to run linkage mapper tools in ArcMap 10.5 version and it shows some errors Thanks
  6. Least cost method in Arcmap

    Thanks I ll try that
  7. Least cost method in Arcmap

    yes, If you are using 10.5.1 I assume you have original license from ESRI, I suggest you to try ArcGIS pro, if you have access to arcgis online organizational license, it is more stable, and if you make a model using model builder, it has new tool called cost path as polyline, so your workflow will be simplified,
  8. Last week
  9. Least cost method in Arcmap

    It started to work now. As you said it must be just some random error due to software issues:) Thanks a lot
  10. Least cost method in Arcmap

    @pasfans, Thanks for the reply. I use ArcMap 10.5.1. I was trying to use this tool to learn how it works. So i was using dummy files and that may be the problem. I drew a point in the map using editor and assumed it as origin. Do you think that would be the reason for the error ? All the best with your thesis
  11. Least cost method in Arcmap

    what arcgis version you are using? I currently working on my thesis about LCP too, and for ArcGIS 10.6, the cost distance tool sometimes giving up random error failed to process, now I moved to arcgis pro which is more stable,
  12. Hello again, I was trying to do least cost distance using ArcMAp. I tried to run least cost distance tool and it shows error as 999999. The input raster used in the cost distance tool were 1.A raster file showing the origin 2. Resulting file from a weighted overlay tool. I think the raster file showing the origin has some problem which stops the operation. I was trying with a dummy point to know how this funtion works. Is it because of that? I first made a point shape file in the map and then made the point shape file into a raster file. This was then used for the least distance operation. Waiting for some replies. Thanks a lot, Maya
  13. 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.
  14. Detecting plant disease by remote sensing

    So far, I have collected data on plants with blight(in a test field), but I will collect data on plants without blight in the coming season. And, yes if I find this out, I'll certainly publish my results. And I appreciate your response to my question.
  15. Detecting plant disease by remote sensing

    It could be the correct approach, but it's basic or applied research that will take trial and error through scientific process. There is no canned answer. There are plenty of studies that support NDVI, or other vegetation indices (both narrow and broadband), serving as a proxy for crop health, vigor, LAI, etc. Red edge has also shown promise in detecting the subtleties between a green, healthy plant and a relatively green, unhealthy plant. The common denominator among these studies are field data; field data that has been collected in a meaningful and statistically rigorous manner so you can model the relationship between a vegetation index and the phenomenon of interest, in this case blight. Have you collected ground truth data on plants with blight and plants without? Can this be discerned at the spatial resolution that you are collecting at (5 meter overhead)? If you find this out and can recommend optimal collection parameters and methods using UAS to detect blight, then I highly suggest that you publish your results.
  16. Hello, I was trying to add several raster layers with values 0 and 1 using raster calculator. The raster layers have different spatial extents so i used the layer with maximum area as the processing extent in the calculator. But the results are weird and range of results are ranging from -2000 to +2000. Why is it so or am i missing something important while doing raster additions? Please drop in your comments. Thanks in advance, Maya
  17. Hi, I want to develop a workflow to detect a specific disease in potato plants(potato blight) by remote sensing. I have acquired the images of the potato field by mounting a multispectral camera on a drone that flew at an altitude of 5m above the plants. The multispectral camera has 5 bands namely: Blue,Green,Red,NIR and RedEdge. I have converted the DN(raw digital number) values of all bands in reflectance values and also applied lens correction and also aligned them. I have first trained SVM(support vector machine) to segment soil from plants and then also applied SAVI(soil adjusted vegetation index) to refine soil segmentation from plants. Now, I want to apply NDVI(normalized difference vegetation index) to determine the heath of plants pixel wise. Is it the right approach to follow? Will NDVI be resonable to apply on images taken at just 5m height? Or is there any better approach? Best regards...

  20. Web-based GIS and Mapping Course

    Event: Web-based GIS and Mapping Course Venue: Indepth Research Services, Nairobi, Kenya. Event Date: 26th March – 30th March 2018 NITA CERTIFIED RECENT CLIENTS INTRODUCTION Web mapping focuses on disseminating and processing geographic information by means of Internet and World Wide Web. Combination of the web and GIS (Geographic Information Systems) has unlocked the potential of GIS, and put online maps and geospatial intelligence in the offices/homes of millions and the hands of billions. The increasing flexibility and interoperability of web mapping technologies has opened new opportunities for Web Based Mappers. Both non-GIS users and GIS experts can do more now, than ever to share maps over the internet. Web maps can easily deliver up to date information, maps are generated automatically from databases, and they can display information in almost real-time. They don't need to be printed, mastered and distributed. Web GIS has immense applicability to e-government, e-business, e-science, and all aspects of daily life. Government employees can utilize Web GIS to improve public services delivery and boost collaboration across agencies. Regardless of the sector, businesses can use Web GIS to enhance their existing business models and create new ones. Researchers can find new solutions to meet the challenges of the new frontiers. Web GIS has great practical value to our world today and into the future. WHO SHOULD APPLY?

  21. DRONE SURVEY GUIDELINES IN INDIA

    Do anyone have any Government guidelines for Drone survey in INDIA. Is it possible to have lidar based drone survey in INDIA. Any Idea about Octacopter capable Lidar camera......
  22. Mutli criteria analysis using Arc Map

    Like wrote rahmansunbeam, is hard to say and recommend a right process , perhaps other idea is that you ask to solar panel specialist and together define many factor and variable and the influences that each one have in the suitable places selection, generally the Multicriteria analysis need of interaction of a lot specialist.... is easy if understand the proceso , the how to, for select the suitable places for a solar panel.... good luck regards .
  23. 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.
  24. Best options to find suitable places for a solar panel installations using multicriteria anlaysis with Arc-Map.Please add in your suggestions
