Hi,
I am writing an application to manage sales territories. A Territory can be made of 1 to x zip5 codes (up to 1000+) . I need to keep historical information about territory shape(s) changing overtime. Of course in order to make the response time acceptable I have to sum all the ZIP5 code shapes using "union" but this is a very time consuming process then to make it possible I am creating these shapes in batch mode. The resulting shapes (bin serialized layer) will be show on the map with a better response time.
Now the question is : how can I keep bin layer files overtime? If you change the layer class then I won't be able to reload the binary or maybe even XML... Any possibilities for Thinkgeo to implement class versioning management?
Thanks for your support.
