Working With Spatial Data

Files vs. Objects

If you take a look at the Scripting Reference, you'll see that the transforms will take objects containing raster or vector objects. The approach we recommend is to load your data into an object and then keep it in memory passing it from one transform to another. You'll find that this is much faster than a file-based approach and does not clutter up your disk with a lot of extra files. The one downside is that intermeediate files are not saved so you'll need to save them if needed for debugging.

You can also load data into an object in BlueSpray and then work on it from a script. You can do this either with data in the ProjectTree where you'll be able to see your script working or just by working with the data in your script.
