comment How can I Normalise Drunk Driving and Postcodes data?
@Simon - OK, I misunderstood the meaning of 'incident'. I assumed 'incident' = 'accident'.

If available one possibility is to normalize by total number of accidents: 'number of driving incidents / total number of accidents'

comment Which true type editor do you use to create/modify point symbols for GIS?
+1. Thanks for the approach of creating true type fonts with fontforge based on *svg files (created with inkscape). I like this approach because inkscape is already the standard vector graphic software in our company.

@PolyGeo Thanks for your comment. Reading the answer of Devdatta Tengshe I thought my question would be OK. If I ask for “a tool to create these five symbols“ I thought the question would be "too localized".

comment How to calculate total number of data cells in raster?
The „zone raster“ can be a raster dataset or a polygon dataset. If you use the polygon dataset then the polygon is converted internally to a raster dataset. If you want to use the same forest polygon for all thousands of fires then it will be faster if you convert it to raster first.

comment How to calculate total number of data cells in raster?
@McVegas To calculate total number of all pixel/cells in a raster use GetRasterProperties_management() with COLUMNCOUNT and ROWCOUNT parameter.

comment How to calculate total number of data cells in raster?
As proposed Zonal Statistics is the solution for 2nd part of the script. But are you sure that 1st part returns what you want? GetCount_management() returns the number of rows in a table. In your case it returns the number of rows in your raster attribute table. A row in a raster attribute table does NOT represent one cell/pixel; it represents a zone.

Does each projection has allways one (or more) standard lines? So does non-equidistant projections have one (or more) standard lines?

comment Performing a reverse clip in ArcMap?
Another workaround to „erase“ with Baisc (ArcView) or Standard (ArcEditor) license is to use the Union tool and Select by Location tool. @MappaGnosis describes how it works in his answer of this question.
