Hi folks,
I'm trying to implement a kind of 'feature generalization' so that the feature data in my WFS responses will be appropriate to the map zoom level. I see two basic techniques I could use to do this: 1) Use different shapefiles at different zoom levels 2) Use GEOMTRANSFORM somehow Of these two, GEOMTRANSFORM seems like the least hassle. However, I can't seem to figure out a way to factor in my map's scale into the amount of shape simplification. When I'm zoomed out, the shapes should be simplified a lot. When I'm zoomed the whole way in, I should be using finer detail. Is there a variable I can use in this expression? GEOMTRANSFORM (simplifypt([shape], [map_cellsize] * 10)) [map_scale] would be nice, if it existed. Thanks, Tom
