On Qgis Is there any extension to get all upstream sections of a polyline shapefile which represent an hydrographic network? It could work like this: You choose a specific branch and a direction then the algorithm will select all the sections recursively until you have all the branches...

I have a Leaflet map that I am using to render a map of the U.S. The map will have specific zoom levels. For example, when the map first loads it will show major U.S. cities. Then if you zoom in it will show more cities on the point where you zoomed. I already have this set up in Leaflet using...

I am relatively new to versioning and think I have made a mistake in my workflow. I am using a SDE geodatabase, with a DEFAULT and 'Field Editing' child version in ArcGIS 10.3. I received a lot of new data, so populated the DEFAULT version using the Object Loader tool - this works fine...

I have a project that repairs broken datasources. One goal of the project is to add the datasource of a featuredataset to repair any broken feature classes. However, so far the only way I've seen to get the FeatureDataSet is through the FeatureClass. However, since these layers are invalid...

I realise this is probably a long shot given the amount of discussion around this issue, but I wonder if anyone has found a workaround to get Qgis to delete shapefile elements properly (see bug 11007) that does not involve saving the shapefile as a new layer. I have over 20 virtual fields...

I try to use near table between two datasets to calculate the nearest distance. The original data is as the right one, and the near table generated is as the left one. The problem is the attribute of "IN_FID" and "NEAR_FID", none of them keep the correct values from the data. The ID number is...
