(In particular: abandoning topologically-aware formats.) | |

| Nov 3, 2010 at 13:31 | comment | added | Jakub Sisak GeoGraphics | When i worked in forestry techs would often union such layers together (results of manual digitizing) which resulted in anomalies that we called "slivers". We were required to eliminate slivers smaller then a certain size and it wasn't an easy process; programmatically identifying which polygon should a sliver merge to based on predefined set of criteria,etc. There are some tools you could try but they work with area size which i found is not often desirable: arcscripts.esri.com/details.asp?dbid=14672 | |
