I'm trying to use GeoModel python module to quickly access geospatial data for my Google App Engine app. I just have a few general questions for issues I'm running into. There's two main methods, proximity_fetch and bounding_box_fetch, that you can use to return queries. They actually return a result set, not a filtered query, which means you need to fully prepare a filtered query before passing it in. It also limits you from iterating over the query set, since the results are fetched, and you don't have the option to input an offset into the fetch.
Short of modifying the code, can anyone recommend a solution for specifying an offset into the query? My problem is that I need to check each result against a variable to see if I can use it, otherwise throw it away and test the next. I may run into cases where I need to do an additional fetch, but starting with an offset.
