We have a model builder routine for locating surface water and saturation that we would like to convert fully or partially to ArcGIS API for Python to analyze imagery services. We are having difficulty finding examples of how to apply the iso-cluster image classifier using the API There do not appear to be any examples of using the raster analytics functions in the docs and online (see links below).   https://developers.arcgis.com/python/api-reference/arcgis.raster.analytics.html https://developers.arcgis.com/python/api-reference/arcgis.raster.analytics.html#arcgis.raster.analytics.classify   We are interested in getting some help or documentation that shows an example of using the ArcGIS API for python to perform unsupervised classification like Iso Clustering.   ...

I have a mosaic dataset with 10 images with different Acquistion Dates. I want to populate a layout with a time-lapse series of images, so that I can show how an area changes over time.  I have written the following code to Make a new image layer by querying the Mosaic Dataset's Footprint for a specific acquisition date. #initialize arcpy and create project / map objects import arcpy  aprx=arcpy.mp.ArcGISProject("Current") cmap=aprx.activeMap() #get unique values from field def unique_values(table, field): #returns all the unique values in a field     with arcpy.da.SearchCursor(table, [field]) as cursor:         return sorted({row[0] for row in cursor}) vals=unique_values("S_Mosaic_Vendor_ComSat\\Footprint","Acquisition_Date") # Grab the unique acquisition dates #Create new raster layer from Definition Query  def_query = "Acquisition_Date = timestamp '" + vals[5].strftime("%Y-%m-%d %H:%M:%S")+"'" #definition query string lyr_name="Image_"+vals[5].strftime("%b-%d-%Y") #layer name string arcpy.MakeFeatureLayer_management('S_Mosaic_Vendor_ComSat\\Footprint',lyr_name,def_query) The problem is I only get the first image date to show up regardless of what Date I query for. Am I missing something or is this part of ArcPy still buggy? I am running ArcPro 2.3.4. I am going to try upgrading to 2.4 next week. ... View more
