I´m using a QGIS 2.8.3 and I want to define a style for the legend of my polygon layer. I was using this code that works perfect: str1= 'C:/Documents/Layer.shp'myVectorLayer = QgsVectorLayer(str1, 'Layer', 'ogr')myTargetField = 'FWI_AROME'myRangeList = []myOpacity = 1# Make our first symbol and...

For the purposes of spatial interpolation, I have created a grid using "Create Fishnet" in ArcMap10.2 (I use the "label points", which have a spacing of 0,00833333 degrees). For every point (label point) I want to have the mean elevation (aspect,curvature) in 800m. around the point. Any ideas...

I am using the OSM open Roads WMS layer that comes included with MapInfo. I have noticed that when I load this layer the projection of the Map window changes to 'Popular Visualization CRS.' All the other layers I use are set to British National Grid. Is there a way to change the projection of...

Is it possible to create a buffer around neighbouring polygons, so that the new polygons do not overlap? Preferably in QGIS but any other tool will do. So instead of the first result I would like to obtain something similar to the second: أكثر...

I'm implementing a kml layer in a map using Google Maps Javascript API, and I'm using QGIS to create the kml file from a shp file. In order to view the extended data in the kml file in Google Maps, it seems like each polygon in the kml file needs to have a unique placemark id, but that is...

I'm new to GIS and confused by all the systems that are used to request data. Every provider seems to use a different system.What I need is to request an area between coordinates (WGS-84) as a picture. This is very easy by using bbox=...... in the URL on WMS-servers but those seem to be slow and...
