Today I have used a Swiss Grid Projection in ArcGIS to plot some data for a student. I have got all the info from this nice site SWISSTOPO, and I ended up to have a very nice distorted map of the globe.
I did it! I have just found a nice way to extract the maximum field value from a bench of records previously selected. The trick is to build up a Python list L = [], where I can append all the selected items L.append =(row.fieldname). Next I can run max(L) to extract the maximum value.
