I am working on a Python Add-In using ArcGIS 10.2.2 where the user can draw lines and the Add-In will add dimension annotation showing length for each segment of the line that is drawn. I can get this working just fine and the text is angled properly, but the OnLine() method does not use...

As a component of my add-in, I compute a bunch of summary statistics when the user clicks a button. This can take a while to process and it can appear as though the program has stopped responding. I would like to add a dialog box which can indicate to the user that the program is still...

I am having troubles with displaying attribute values in IntraMaps Roam. Let me give you more details: My QGIS project is based on an SQLite database The attribute table in QGIS is displaying the attribute value (which is text) and not the unique ID's (numbers) that belong to each...

I need some help. I manage to get Ukrainian topographic map to my project. I'd like to do the georeference in QGIS. Problem is I don't have a clue what the projection is and how to read the X and Y coordinates in those maps. I don't know Ukrainian as well. Please help. LINK TO MAP...

I'm developing a Qgis plugin to use my own raster resampling method rather than what is provided in Qgis (cubic/bilinear). And so, I've extended the QgsRasterResampler class. However, I'm having difficulty getting resample method to work. Based on the C++ api documentation for resample...

I have a countries boudary shapefile for the whole world (from Diva GIS). The countries in the shapefile are multipart polygons but when I import it to PostGIS 2 using the gui shapefile loader the resulting table splits the multipart polygons into single part polygons. I have tried the...

As part of my thesis, I have to analyse four parts of an area in Northern Peloponnese, Greece, according to land use. I have downloaded the shapefiles of the general area from corine. I have merged the color values as I had to use two shapefiles. What I have to do now is to isolate four specific...

I am validating shapefiles polygon geometry using shapely, and have also attempted it using FME. Some polygons return the error "Nested Shells". I cannot find a definition of what the problem is, whether in FME documentation (here) or in google search results on shapely or OGC geometry...

I want to calculate the field "area_type" with text depending on numbers from the "Value" field. I have tried with the following VB-script in "Field Calculator" but am getting this error message: "The calculated value is invalid for the row with ObjectID = 1. For example, the calculated value...

In an experimental Python AddIn that I've created using ArcPy from ArcGIS 10.3 for Desktop I have put some test help into my config.xml for a button called Button4: When I make and install my Python AddIn, the message and tip show up by mousing over the button as expected. However, I have...

I wish to create one "image" showing a large area cloud free for further composition. Base are landsat images. As the area is too large and on all images there are clouds i wish to only use the regions without clouds on individual images and than "stitch" them together to create one large file...

My goal is to create an interpolation map of some output model results that are mapped on a deformed mesh (from a numerical simulation). The model results are in an x-y plane (representing coordinates) with a variable-z to interpolate, however the coordinates are irregularly spaced and have an...

I am using a custom map marker icon which works well as expected. However as I navigate , the direction of the marker pin on map changes. I have tried changing the coarse symbol and heading symbol as well. But that doesn't work. Here's the screenshot. http://i.stack.imgur.com/XXawl.jpg How can...

I am trying to export individual shapefiles of all 2 pair combinations from a multi-feature polygon shapefile. To explain this better as set of FID's 0, 1, 2, 3, 4 would be exported as individual shapefiles of FID pairs: ('0', '1'), ('0', '2'), ('0', '3'), ('0', '4'), ('1', '2'), ('1', '3')...
