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.

Empowering Action — New Tools for Crisis and Humanitarian Response

This week several members of our team attended the 3rd International Conference of
Crisis Mappers (ICCM)
that was held in Geneva, Switzerland and we were blown away by the turn out (Follow #ICCM on Twitter).  This community has grown substantially over the last 3 years – when we attended the first conference held in Cleveland, Ohio back in 2009 there were about 100 attendees.  Now there are more than 400 gathered here discussing crisis mapping and the challenges they face.  There are really 3 main things that we keep hearing as it relates to GIS and mapping: Continue reading
