I don't know whether you consider Computer-Aided-Dispatch (CAD) under the rubric of "GIS software", but our project, Tickets CAD, certainly does integrate data with mapping/geo technology. And it's free, and Open Source predominantly, See at <a href="http://www.ticketscad.org">www.ticketscad.org</a>.<br>
<br>And it is being used in some public safety operations. I will have to poll our users for permission to provide site names. <br><br>Please understand the political ramifications of such usage: An agency has years of unsuccessfully requesting budget $ for the purchase of a commercial CAD product, which they demonstrably need, and now - suddenly - a free one surfaces. Best is probably to do it quietly and avoid raised eyebrows and questions.<br>
<br>(CAD may well be among the earliest examples of such integration.)<br><br>AS<br>Tickets CAD Project<br>Lead (the adjective, not the noun!) developer<br>
