Free Geography Tools is a great blog for finding exactly that, free widgets to enhance your geographic and mapping-related work. A couple of recent posts highlighted these tools: This post highlights a tool to edit .dbf files. While this post introduces a desktop utility to convert DMS to Decimal-Degrees. Another cool utility that Maggie recently introduced me too is the GeoPDF toolbar, which allows users to explore map layers within Adobe Reader. The format is very similar to that of ArcMap, allowing for searches by attributes and for layers to be turned on and off. An additional tool, Map2PDF, allows users to export GeoPDF from ArcMap. If you want to download the GeoPDF toolbar, I have attached a map as an example.
