Apologies, I went off-list by mistake. There are selectAndCreateNewShapefile methods in: https://github.com/agdturner/digital-welfare/blob/master/src/main/java/uk/ac/leeds/ccg/andyt/projects/digitalwelfare/mapping/DW_Maps.java
The transact method is in: https://github.com/agdturner/digital-welfare/blob/master/src/main/java/uk/ac/leeds/ccg/andyt/projects/digitalwelfare/mapping/DW_Shapefile.java I call these from deep within the loops of the mapCountsForLevel method in: https://github.com/agdturner/digital-welfare/blob/master/src/main/java/uk/ac/leeds/ccg/andyt/projects/digitalwelfare/process/DW_ChoroplethMaps.java The other main classes where useful code for this might be are in: https://github.com/agdturner/digital-welfare/blob/master/src/main/java/uk/ac/leeds/ccg/andyt/projects/digitalwelfare/mapping/ I am moving all the generic things to a separate project in the very near future as I have another project that will be doing something similar and abstracting things like this out seems best. So that code is moving to: https://github.com/agdturner/agdt-geotools I hope to abstract the code and get this working for another project next week.
