I have some coastal 4 band imagery that I have classified to designate land, water, and undetermined. I want to convert this to polygons with topology, and significantly simplify the polygons.
If I convert the raster to vector, then try to apply a topology, then simplify the polygons, Arc Crashes.
(Raster to Polygon>Select By Attribute x3>Export to FeatureDataset as 3 separate classes>Create Topology in ArcCatalog. Started with only Can't-overlap-self rules, but have also tried Can't overlap each other rules, as well as trying one rule at a time. I have tried validating in Arc catalog, with a validation failed error followed by an ArcCatalog Crash. I have tried not validating until in an edit session in ArcMap, which results in a freeze then a crash. I deleted the topology after each error and started a new one.)
If I try to split these polygons, I get the empty output bug in ArcInfo.
(Raster to Polygon>Select By Attribute x3>Export to FeatureDataset as 3 separate classes> Extract/Split tool using a fishnet as the split features> Processes Polygons, completes without error, copies everything from dataset of input feature to Target Workspace, doesn't split polygons. Have seen threads from older versions having this bug.)
If I convert raster to vector, then simplify, I end up with tons of gaps and overlaps left to fix. (Which defeats the purpose of going to a topology first.)
I've got to think this is a fairly common conversion. Is there a specific trick or workflow that I am missing here to accomplish this? Or am I at the mercy of ESRI bugs?
ArcMap / ArcInfo with spatial analysis version 10.0 SP5.
EDIT:Added specific workflows above. Although I've tried a few other variations using mostly the same tools. The usual save and close between steps. Export as a whole before exporting by attribute.
