I have some data in a texfile where the coordinates are given in this format: lat lon23S19.69 66W45.8724S01.73 66W55.61I already learned that it is some kind of WGS-84 with degree and decimal minutes. My goal is to save the coordinate in a point geometry. ST_MakePoint(lon, lat) does not...

I have two postgis layers: The first layer contains the sidewalks of my town (polygons in blue). The second one contains the pavements (roads) of my town (polygons in brown). The map looks like this in QGIS with both layers activated: Ok, now I have to obtain a layer with the curbs (lines)...

I'm having a hard time adding my grid to the map and changing its symbology with an existing lyr file. I have found a great post by Neil Clemmons that explains this, but it doesn't work for me. I tried this code: Dim map As IMap = pMxDoc.FocusMap' make new layerfile and open lyr file Dim...

I have a ncdf file containing measurements covering a satellite orbit. The ncdf contains the corresponding latitude / longitude fields but they ar irregularly spaced. I tried rasterizing the values by extracting the lat,lon,z values but on northern and southern latitudes I then end up with...
