Some KML clients cannot draw features with more than 30k vertices

解决办法

Run the following script from the python window to determine if you have any polygons where a single feature has more than 30,000 vertices. You can then generalize or split the polygon.Note - ArcGIS Explorer does not have any issues with drawing KML that has a large number of vertices. The issue is specific to certain clients and their inability to draw more than 30k features.import arcpy, osoverLimit = []mxd = arcpy.mapping.MapDocument("current")df = arcpy.mapping.ListDataFrames(mxd)[0]for lyr in arcpy.mapping.ListLayers(mxd, '', df): inFeats = lyr.dataSource if arcpy.Describe(inFeats).shapeType == "Polygon": print lyr.name desc = arcpy.Describe(inFeats) rows = arcpy.SearchCursor(inFeats) shapeName = desc.ShapeFieldName for row in rows: feat = row.getValue(shapeName) if feat.pointCount > 30000: overLimit.append((lyr.name, row.getValue(desc.OIDFieldName), feat.pointCount)) del rows del shapeName del inFeats print "==================="if len(overLimit) == 0: print "Nothing over 30k"else: print overLimit
