Location in Polygon

[Hans-Joerg]

Hello,

I wonder if there is a possibility to get all objects of an information layer which are contained within a specified polygon (geo coordinates).
There is a method "InformationLayer.GetElementsInRectangle" wich is almost what we need.

best regards

Hello Hans-Joerg,

If polygon is a map shape object is visible over the map, then you can use following method to detect whether specified location is inside the shape:

private bool IsLocationInShape(MapShape shapeToTest, Location location)
{
    bool isInShape = false;

    IEnumerable<object> list = this.InformationLayer.GetItemsInLocation(location);
    foreach (object item in list)
    {
        MapShape shape = item as MapShape;
        if (shape != null && shape == shapeToTest)
        {
            isInShape = true;
            break;
        }
    }

    return isInShape;
}

Then you can loop through the list of the objects and use this method to detect whether the object location is inside the specified shape.
