  1. Hi everybody, This forum is awesome I was looking for Python for GIS lessons for beginners since I know nothing about this language Habboub
  2. Hi all, I'd like to share a tool I created to automate the calculation of spectral indices for remotely sensed imagery. Currently, 22 spectral indices and the following sensors are supported: Landsat 1-5 MSS Landsat 4-5 TM Landsat 7 ETM+ Landsat 8 OLI Worldview-02 MODIS Terra and Aqua Just run the Python script (arcpy or GDAL) and use the GUI interface to select your sensor, indices to calculate, stacked image, and output directory. I haven't shared the tool yet and thus it has not been extensively tested. My personal tests have worked fine, but be sure to validate y
  3. Hi, I am now trying to build a python based image processing simple application. However I found out that the perfect match library rsgislib is compatible in Unix like environment. I don't know how to use it like normal libraries in Windows environment. Is there any substitute library for rsgislib, or is there a way so that I could let it compatible with windows environment? rsgislib:http://www.rsgislib.org/ Sincerely,
  4. I've written a arcpy script that creates terrain datasets from LiDAR. After 18 hours it bombed. Instead of starting the entire process over again, I want the script to pick up where is failed. How do I check, with arcpy/python, if a Terrain Dataset has pyramids? If it does, then how do I check if the Terrain Dataset has data sources already added to build the terrain? Basically, how do I access the Terrain Model Properties to check for... anything really... so that I can verify that they exist or not? This is a fairly simple process for just about every other kind of feature using cod
  5. Hello There! Would like to share this link for those interested to code in python and make maps =) http://sensitivecities.com/so-youd-like-to-make-a-map-using-python-EN.html I was able to create 300 of these maps in 2 hours after reading this. =) Also done this to visualize the extent of damage due to storm surges brought about byTyphoon Haiyan (Yolanda in our country name) in Tacloban City, Eastern Samar.
  6. 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.

  8. Kartograph is a simple and lightweight framework for building interactive map applications without Google Maps or any other mapping service. It was created with the needs of designers and data journalists in mind. Actually, Kartograph is two libraries. One generates beautiful & compact SVG maps; the other helps you to create interactive maps that run across all major browsers. Kartograph.py A powerful Python library for generating beautiful, Illustrator-friendly SVG maps. Renders vector maps from shapefiles and PostGIS Compact SVGs using Visvalingam simplification Stores metadata
  9. It's been a long time since Guido van Rossum, a Dutch programmer, invented the high-level object-oriented programming language called Python. No sooner the language hit the community, it spread like fire. The true power of python is that it's free, fully open-source, easy to learn and understandable, well documented high-level programming environment. Like any other community, GIS also thrived with it. From OSGeo to the mighty ESRI, everyone is somewhat using Python in their projects. New tools, apps and websites are making way. Developers are building new frameworks and modules for it. In th
  10. I think, this will be good idea to share python codes to learn and get support from the members. Under this post we can do that. Can anyone help to delete subtype field from a feature class (FC)? Like one FC may have a subtype field with 5 (five) predefined subtypes. How to read and list those five subtype values and remove from the subtype list dynamically and finally delete the field. Just now thought about this. Will work on this to get solution. Please share your views and post how you learnt Python for customizing ArcGIS Desktop and Server.
