Creating Flow Direction in ArcGIS 10.2

JessiecarEsguerra

Hi,

I am trying to create a Flow Direction from DEM Raster File using ArcGIS 10.2.

I was able to complete a few files and get an output for flow direction but there are some files that I encountered an error.

Error showing is below.

010067 : Error in executing grid expression.

I would really appreciate any input, comment or suggestion to fix this problem.

Thanks in advance!

lots of potential error: including: Filenames > 13 characters and/or contain spaces or begin with a number; file paths that contain spaces etc.

More details are needed

Hi Dan,

Thanks for your inputs but I'll check on filenames and file paths. We are good with regards to number of characters and filenaming convention. Can you give me more insights on the error referring to "grid expression"? What other details you need for you to be able to help me on resolving this issue.

I do appreciate your inputs. Thank you!

For example, what your workflow up to creating the flow direction? Did you do the standard operations of filling sinks? were you running this in Arctoolbox, did you expressly set the analysis extent and cell size in the tool within Arctoolbox or did you rely on default raster settings. Grid expression is sometimes generic...sometimes due to a mistake in the processing steps

I actually run the DEM raster file using ArcToolbox. I will run it first in "Fill" then use the output in running "Flow Direction". I am just relying on the default raster settings. Do you think there is mistake on the creation of raster file? If so, is there a way I could repair it just like "Repair Geometry" in Feature Class?

Thanks!
