How to add Raster Mosaic to Map from Enterprise GDB (PRO SDK)

DevonCanady

I am able to connect to an sde geodatabase and obtain a handle on a raster dataset, but I can't figure out how to add this dataset to my map. I don't see how I would use a Uri since it doesn't exist in a file, and I don't know how to obtain an Item or CIMDataconnection from a RasterDataset type - since these are the three data types allowed in LayerFactory.Instance.CreateMosaicLayer().

Devon,

That is a good question. You don't need the raster dataset object to create a layer, you have all the information you need before that step already. Once you have a geodatabase object, you can create a CIMStandardDataConnection object using it and then use that to create a mosaic layer. Sample code below.

// Create the data connection object.

string workspaceConnectionString = geodatabase.GetConnectionString();
CIMStandardDataConnection dataConnection = new CIMStandardDataConnection();
// Setup the data connection object.
dataConnection.WorkspaceFactory = WorkspaceFactory.SDE;
dataConnection.WorkspaceConnectionString = workspaceConnectionString;

dataConnection.DatasetType = esriDatasetType.esriDTMosaicDataset;
dataConnection.Dataset = "<SPAN class="">sdeDOQTX1996.DBO.Zone14_mosaic</SPAN>";

// Create the layer.
rasterLayer = (MosaicLayer)LayerFactory.Instance.CreateLayer(dataConnection, map);

You can create a raster, mosaic or image service layer using the CreateLayer method.

Hope that helps.
