示例1: mergeAbuttingPolygons
private static IFeature mergeAbuttingPolygons(IFeature shape1, IFeature shape2)
{
if (shape1 == null) return shape2;
if (shape2 == null) return shape1;
IFeature mergeShape = null;
// check both shapes are single parts
bool areSingleGeometryFeatures = (shape1.NumGeometries == 1) && (shape2.NumGeometries == 1);
if (areSingleGeometryFeatures)
{
mergeShape = shape1.Union(shape2);
}
else
{
Trace.WriteLine("Error - there were multiple parts.");
//mergeShape = new IFeatureClass();
//mergeShape.Create(MapWinGIS.ShpfileType.SHP_POLYGON);
//SpatialOperations.MergeShapes(shape1, shape2, out mergeShape);
}
return mergeShape;
