Using OpenLayers 2, I want to have an offline baselayer, that is loaded from a KML or GEOJSON file. I am successfully able to do this if I first load a baselayer from google maps. For example, this works fine and am able to properly switch between the two layers: var googlePhys = new...

I have a line and need to get a list of coordinates (points) where the line crosses the polygon(s). A line could cross multiple polygons. A line could also only cross one side of polygon, if the line starts inside the polygon. ST_CROSSES returns a bool indicating if the line crosses but I need...

What is the BEST way to preserve original raster values as attributes in the output raster when reclassifying? I see that this question has been asked before.

I'm pulling in data from ArcGIS using ArcGIS.PCL which provides the geometries as GeoJson. I'd like to convert this GeoJson to KML. Does anyone know of any .NET libraries that provides this functionality? I've had a good search but nothing has popped up on my radar. I guess a couple of...
