A few weeks ago, my company announced the availability of the first beta version of WeoGeo Tools for ArcGIS. Unlike the previous version, which opened a separate browser window, this new release allows a user to order a data set from WeoGeo Market or a library from inside ArcMap.
One of the challenges was enabling data set previews. If you browse data sets using the WeoGeo online tool, you can get an idea of what the data set contains by using the data set preview images supplied by the data set provider.
When we developed the first version of WeoGeo Tools for WeoGeo, they used kamap to create preview tiles for data sets. This was accomplished by used either one of two desktop tools: the weoapp (command line) or gWeoApp (GUI). The first version of WeoGeo Tools used the weoapp in the background to create tiles when uploading data.
