sorry I forgot the .shp extension. for fc in fcs:     output_path = fc[:-4] + "_buff.shp" or as Joshua says: for fc in fcs:     output_path = os.path.join(fc[:4], "buff.shp") or even better as Joshua says, save it as a feature class. ... View more

currently you're trying to add "buff" to something with a .shp extension I guess? for fc in fcs:     output_path = fc[:-4] + "_buff" ... View more

The easiest way is to symbolise the data in the classes you need, then drag that layer into the Reclassify tool, which should add those break values for you to change. here is the difference between geoid and ellipsoid it can be recoded by the Reclassify tool ... View more

Check the geometry of your input and repair if necessary. Check the transformation is being populated with hungarian1972 to wgs84, also check the environments output coordinate system and processing extent, as ArcMap loves to randomly add a transformation.  ... View more

Dan is correct in how to convert this, however this may also be a mis-understanding of the percentage slope.  This is rise/run *100, meaning a 100% slope is 45 degrees, and a 330% slope is 73 degrees. ... View more

I've updated it to arcpy.sa.Con... I've tested it with dummy data on my system and it works. If this doesn't work i'd suggest it's a corruption of your raster(s) or a file naming or path issue. import arcpy import os arcpy.CheckOutExtension("Spatial") arcpy.env.workspace = r"D:\test" out_workspace = r"D:\output" #InMask = r"E:/JASTTpaperWork/Data/Shapefile/KRG.shp" # Get a list of grids in the workspace. rasters = arcpy.ListRasters("","TIF") for raster in rasters: # Set the outputname for each output to be the same as the input. output_path = os.path.join(out_workspace,raster) #create raster object raster_path = os.path.join(arcpy.env.workspace,raster) raster_object = arcpy.Raster(raster_path) #return conditional raster con_raster = arcpy.sa.Con(raster_object <= -1, 0, raster_object) #save it con_raster.save(output_path) arcpy.CheckInExtension("Spatial") ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...

Try hardcoding a different path as the out workspace. look at your path formatting and check against examples in the esri help. There's no need to keep adding those modules - sys, string, arcgisscripting, math. it just slows down your process.  ... View more

I've changed this to arcpy.Raster if that doesn't work try arcpy.Raster(raster) ... View more

I'm not familiar with this tool so I'm going to offer some very vague and probably incorrect advice! The output seems to be a group layer which might be causing the issue, could you package it up into a zip file to download or does it need to be added as an operational layer or add some code to add the individual layers? Have you looked at all of the options for the output in the publishing window? ... View more

Hi Jeremy, In the desktop environment (written as code to run as a script or script tool) one way this could be implemented is to set up you mxd at the required scale, including all the data and labelling you would expect/like to see if you manually zoomed or panned around the map. In the code I would use a query to select your address feature and grab its SHAPE@ geometry token.  Using this I would then use the pantoextent method of your current dataframe with arcpy.Mapping.  Hopefully this would  then centre your dataframe on the address whilst keeping the required scale.  Then an ExporttoPDF to create your report. In a server environment, this could be published as a geoprocessing task, allowing users to open up a Wep Mapping Application you have designed, then type the address into a geoprocessing widget which spits out the pdf. Another implementation might be to let the user zoom to the address using a geocoding service (address locator etc), then set up their own bespoke labelling and use a custom print service to export what's on the screen. ...
