Hello,
I indexed MultiPolygon using this
IDictionary<string, string> margs = new Dictionary<string, string>
{
["SpatialContextFactory"] =
typeof(NtsSpatialContextFactory).FullName
};
var ctx = SpatialContextFactory.MakeSpatialContext(margs,
GetType().Assembly);
SpatialPrefixTree trie = new QuadPrefixTree(ctx, 12);
_locationfindstrategy = new TermQueryPrefixTreeStrategy(trie,
"geo");
then indexed each polygon via
IShape area = ctx.ReadShapeFromWkt(v.wktstr);
Document doc = new Document();
doc.Add(new TextField("id", v.stname, Field.Store.YES));
Field[] fields =
_locationfindstrategy.CreateIndexableFields(area, 0.025);
foreach (Field field in fields)
{
doc.Add(field);
}
Now I am trying to search documents containing a point (For example , say i
want to find the city from lat/long, and I have stored polygon shapes of city )
IPoint upperleft = ctx.MakePoint(92.515830993652514, 10.8976411819458);
Query query = _locationfindstrategy.MakeQuery(new
SpatialArgs(SpatialOperation.Contains, upperleft));
TopDocs search = searcher.Search(query, 10);
I am getting error - Opeation Not supported
Is there any other mechanism which i can use
