Gmap4 is awesome. The beauty of GIS really shines for tracking fires and floods. What a powerful tool for emergency response management, as well as follow up work after the incident - like revegetation work on steep burned slopes to prevent erosion and mudslides. A picture tells 1,000 words and each data layer adds another 1,000 words of info. But really, overlaid on top of each other can be more like 1,000 x 1,000. The ole saying needs to be updated, a picture may tell a 1,000 words but GIS tells a million.
