There could be several ways to joining data based on spatial relationship. However, using the GP tool Spatial Join is simpler and gives more leverage. Here is a complete code snippet for running Spatial Join with ArcGIS Pro SDK:
protected override async void OnClick()
{
var environments = Geoprocessing.MakeEnvironmentArray(overwriteoutput: true);
var parameters = await QueuedTask.Run(() =>
{
var target_feats = @"C:\\data.gdb\\Buildings";
var join_feats = @"C:\\data.gdb\\Points";
var output_feats = @"C:\\data.gdb\\Points_to_Poly";
var join_operation = "JOIN_ONE_TO_MANY";
var match_option = "INTERSECT"; // WITHIN, WITHIN_A_DISTANCE, CONTAINS etc
var search_radius = "220 Feet";
var field_map = ""; // empty string means default field map that contains all the fields from target and join
return Geoprocessing.MakeValueArray(target_feats, join_feats, output_feats, join_operation,
"KEEP_ALL", field_map, match_option, search_radius);
});
GPExecuteToolFlags flags = GPExecuteToolFlags.AddOutputsToMap | GPExecuteToolFlags.GPThread;
var toolResult = await Geoprocessing.ExecuteToolAsync("SpatialJoin_analysis", parameters, environments, null, null, flags);
Geoprocessing.ShowMessageBox(toolResult.Messages, "GP Messages", toolResult.IsFailed ?
GPMessageBoxStyle.Error : GPMessageBoxStyle.Default);
}
Jeff King - we're in the process of bringing the tool syntax in SDK - like we have now for python for each tool.
