I'm looking for a simple way to replace the value field in GRID format with values that I have in a csv. It would be much like doing a join, where the GRID and the csv have a FEATUREID and then getting a field value from the joined table to replace or to be displayed in the symbology, or to put...

This is what I am looking for: Create two tools in Python Toolbox: Tool1 and Tool2 (I am able to do that) I want to define a parameter in Tool2 whose value depends on parameter entered by user in Tool1. How can I do that? Can Tool1 be called in Tool2 and automatically Tool2 gets the value of...

I would like to execute a 2 step floating catchment area (2SFCA) in ArcGIS. I've been referencing this paper, but something's awry with my output, i.e. various null values, etc. The purpose of this method is to identify the population to facility ratio for medical treatment facilities. I have...

I'm trying to white a Python plugin in QGIS (2.2) to get, for each pixel of a raster image, its X Y coordinates, as well as, its RGB (3 bands) values. At first I opened the raster file using: rlayer = QgsRasterLayer(rfileName, rbaseName) Now I don't know how to get, for example, for pixel...

I just upgraded to QGIS 2.10 (using the debian repos) and the heatmap plugin doesn't show any formats in the dropdown menu. I'm able to open every raster format I have at hand and, of course, the drivers are listed in the gdal driver options. I looked around and found a similar question here...

This is what I am looking to create in a python toolbox: Create a parameter to get geodatabase (.gdb) file from the user. (the .gdb file has some number of feature classes) After user enters the gdb path in first parameter above, automatically create new parameters equal to number of feature...

arcpy.mapping.MapDocument("CURRENT") fails when running python script in background a The engineers I work with have requested an autosave feature for ArcGIS, so I thought I'd make them a python tool that routinely saves. The script works fine when run in the foreground, but fails when "Always...

I am wanting to take a symbolized layer in an mxd, and save it's symbol color (like a polygon fill) into its attribute table as an RGB value. My goal is to use this value in MapInfo to symbolize it's features via Discover. I can't see any obvious way of using the ArcPy mapping module to read...

I am attempting to draw a simple box polygon that overlaps the international dateline. Currently when creating the polygon it wraps in the opposite direction. Full example : http://jsfiddle.net/mcroteau/dkk2yu3L/ Javascript: var wgs84Proj = new ol.proj.Projection({ code : "EPSG:4326" });var...

I have two different raster data : First data : Second data How to combine those raster data? so the output data will be like this : Where the overlap space between First data and second data (the green one) will contains the value of second data and the other will be refer to first data...

The Spatialite GUI can export a Geometry column to KML file. How would one go about doing that from the Spatialite command line? I am looking for an example code preferably - the .help doesn't mention it and the function list is a little confusing to me. أكثر...

I want to loop through all the layers in TOC in ArcGIS and report Raster and Vector Layers. I want to see how many layer are raster and how many are vector. I can access the layers using: IEnumLayer pEnumLayer = pMap.get_Layers(null, true); and loop the layers in Enum, but how do I determine...

I need to add a Description to a Feature Class using arcpy. The feature class lives in our enterprise geodatabase. The Feature Class does not live in an MXD file, nor will it ever for this script's purposes. The following code works in ArcMap when applied to a layer in the Table of...

I am new to Python and coding generally, and I cannot figure out how to set up a debugger that will work with Arcpy. I am trying to use PyCharm, but it always gets caught up with the fact that it can't actually open ArcMap. It gives me this error when I run in the IDE: RuntimeError...

I'm trying to get layers to update automatically when their data source changes. I'm using R to write a shapefile with an attribute, and colouring according to that attribute in QGIS. I want to write a new shapefile with different attribute values, and have the Qgis map colours update. Step 1...

I am looking to convert a pair of coordinates to decimal, and am unsure how to go about doing it. The following script select Centroid.STY as Longitude, Centroid.STX as Latidude from ( select Shape.STCentroid() as Centroid from gis.USA_10_CENSUS_TRACT )U generates these results...
