mosaic dataset add raster duplicates?

gisscconsulting — Mon, 25 Jul 2011 16:38:20 GMT

This ESRI code snipple shows how to add raster to mosaic dataset

http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#/How_to_add_rasters_to_a_Mosaic_dataset/0001000002wv000000/

However, it won't consider exist ones. If you run the method the second time, duplicate records added.

There is "AddNewRasters" in IMosaicDatasetOperation interface
http://help.arcgis.com/en/sdk/10.0/arcobjects_net/componenthelp/index.html#//001q0000018r000000

However, the documents related to that is none.

Any one have successfully used this "AddNewRasters" method in .net?

Are there a way to remove an item from mosatc dataset using .net?

Greetings,

To exclude duplicates on load you need to set the property in IAddRasterParameters:
IAddRastersParameters AddRastersArgs = new AddRastersParametersClass();
... setup crawler etc...
// Exclude duplicates
AddRastersArgs.DuplicateItemsAction = esriDuplicateItemsAction.esriDuplicateItemsExclude;

Hope this helps.

Robert

esriDuplicateItemsAction.esriDuplicateItemsExclude;

It worked just as it said. Thank you
