Take your terrain mapping to new heights

by Kenneth Field, Senior Cartographic Product Engineer

Standard techniques for representing terrain, like a hillshade, are adequate for many applications, but you may want to represent terrain under different lighting conditions, or perhaps use more artistic techniques. In these cases you might need to go a little further than creating a simple hillshade. For this reason (and because we like making tools that extend what we can do!) we’ve built a new toolbox, called Terrain Tools, that helps you take your terrain mapping to new heights.

Critical Space Time Pattern Mining Patch

The ArcGIS 10.3 release includes the new Space Time Pattern Mining toolbox for analyzing data distributions and patterns in the context of both space and time in ArcMap and Pro. Unfortunately this initial release contains a substantial logic flaw in the Create Space Time Cube tool which makes the results from the Emerging Hot Spot Analysis tool unreliable.  We have corrected this problem in ArcMap 10.3.1 and Pro 1.1 and are providing the patches below for your immediate use.  Regrettably you must rerun all of your previous analyses using the provided fix. Internally we have enhanced our validation strategies to ensure this is not a recurring error.
