Using Landscape Image Services in a Python Script

RichNauman

Is it possible to use a Landscape Image Service as a geoprocessing input for a stand alone Python script?

Yes it is, though it is important to access the image service via a connection file that you create in the python code.  Here is the essential snippet of code to use:

    arcpy.mapping.CreateGISServerConnectionFile("USE_GIS_SERVICES", arcpy.env.scratchFolder,
                                                servername + ".ags", "http://" + servername + ".arcgis.com/arcgis/services",
                                                "ARCGIS_SERVER", '', '', userName, passWord, "SAVE_USERNAME")

    # set up image layer from the landscape server connection, and get its spatial reference
    imageService = os.path.join(arcpy.env.scratchFolder, servername, imageservicename + ".ImageServer")
    inputImageLayer = arcpy.MakeImageServerLayer_management(imageService,"imageLayer")

Once you have that inputImageLayer, you can use it to get properties via the arcpy.describe function:

rastSpatRef = arcpy.Describe(inputImageLayer).spatialReference
arcpy.env.cellSize = arcpy.Describe(inputImageLayer).meanCellWidth
theCellSize = arcpy.Describe(inputImageLayer).meanCellWidth

From there you can make a rasterLayer:

arcpy.MakeRasterLayer_management(inputImageLayer, "temp_raster")

And that can be used in many Geoprocessing functions:

arcpy.sa.Con("junk2g","temp_raster")
