Creating a Map Layer from a WFS Response
MapXtreme v7.1 409 Developer Guide
From the filtered GetFeature call, only those rows of data that satisfy
PropertyIsGreaterThanOrEqualTo a population of 1,000,000 are returned. Notice Abu Dhabi is not
included in the results since its population is listed as 722,000.

Filtering with a Spatial Operator
The following example shows how to use a spatial query in a GetFeature request. In this case, it is
asking for all the rows in the Europe table that satisfy the specified minimum bounding rectangle.
This is accomplished using the spatial operator Bbox, a typical spatial operation that most WFS
servers support.
/// Now lets find rows in an MBR
///
// WGS84 - Europe
MapInfo.Geometry.DRect bbox = new MapInfo.Geometry.DRect(-
11.69, 35.36, 48.77, 65.05);
mfc = MapInfo.Wfs.Client.WfsClient.GetFeature(
wfsUrl,
new string[] { featureTypeName },
bbox,
null,
"GML3",
-1);
DisplayFeatureCollection(mfc[0]);
Creating a Map Layer from a WFS Response
If you wish to bring WFS feature data into MapXtreme as a map layer for further analysis, it is
necessary for you to run code that parses the GML and creates a MultiFeatureCollection.
