Selecting Features Within a Polygon [solved]

DrewD

Hello, I was wondering if I could get some help with this problem.

Currently I'm using this line of code to select point features inside of a polygon. 

MapView.Active.SelectFeatures(polygon, SelectionCombinationMethod.Add, true, false);

However I noticed it is not very.. accurate? the description for this method is that it selects features that intersect a geometry, however clearly that's not whats happening as the points are outside of the polygon. What would be a functioning equivalent to the geoprocessing tool Select by Location? As the SelectFeatures method is unclear as to what it actually does.

Any help would be appreciated.

The solution I found was to use a SpatialQueryFilter (below)

SpatialQueryFilter sqf = new SpatialQueryFilter { FilterGeometry = polygon, SpatialRelationship = SpatialRelationship.Contains };

[pointlayer].Select(sqf);

Instead of MapView.Active.SelectFeatures(polygon), which doesn't work properly.

Are you using 2-D or 3-D? The third parameter (isVisualIntersect) is for 3-D while the fourth parameter (isWhollyWithin) is for 2-D. What happens when you use

MapView.Active.SelectFeatures(polygon, SelectionCombinationMethod.Add, false, true);

You should make this a Question rather than a Discussion
