The only way I can think of doing this in a raster environment is to take each raster that contributed to the weighting and reclassify into multiples of 10 then add all these together. At this point I am assuming your weighting rasters were essentially binary in nature. For example you had 4 weighting rasters A, B, C and D and for each raster it had a value ...

Do a weighted overlay with scale from 1 - 100 and then rescale with raster calculator? if the scale is 1 - 100 then you rescale something like [(grid - min value from grid) * (max scale value - min scale value) / (max value from grid - min value from grid)] + min scale value to 1 - 10 but somewhere in there you will need to specify decimals, maybe a weighted ...

For OSM and similar maps, the map.projection has to be projection: new OpenLayers.Projection("EPSG:900913"), or EPSG:3857 if you prefer. Just changing the code number to 4326 does not reproject the tiles automatically, but places them into a wrong part of the world. Since Opnelayers can not perform the reprojection on its own, you have to follow the ...

To do this I would use two tools: Intersect (Analysis): Computes a geometric intersection of the input features. Features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class. then Summary Statistics (Analysis) Calculates summary statistics for field(s) in a table.

One way to approach this would be using Rasters. Raster operations would be faster and more reliable in this case. Convert your vector layers to rasters using Raster -> Conversion -> Rasterize. (Start with a large pixel size to test your approach.) Subtract the rasters using Raster Calculator. convert the result into Vector using Raster -> Conversion -> ...

I was able to resolve this by doing a series of difference queries based on a few shape files I have. Still found not great automated way but it's done nonetheless.

So... here's another script... Eveything is working. The kml layer can be shown and stuff... and I can draw polygons... All I want to do now is to export the map as a PNG. <!DOCTYPE html> OpenLayers KML Example #map { height: 400px; width: 1000px; } .ol-attribution a ...

Thanks to everyone for all of the help! I was able to create an equation in the Raster Calculator (using the Con expression) that stacks my layers and keeps only the visible pixel values. Here is the two-part method that I used: Ran first calculation to stack middle layer (R2) on top of bottom layer (R3) Con("R2" == 2,"R2","R3") Ran second ...
