Missing Agricultural Field Boundary Data

[Jesus Sanchez]

Hi,

I'm currently on Step 3.a1 and 3.a2. I'm working with watersheds in Jersey County and Madison County, Illinois (071100090401, 071100090402, and 071100090403) and I'm missing field boundary data. I'm trying to find a better source to replace it.

Any suggestions on where to look or who to contact?

Thank You!

Jesus Sanchez

Jesus,

 

The core data provided by the ACPF Hub contains field boundary data originally collected from CLU state data in 2008, as you have seen, and if you are finding gaps in coverage of watersheds, that was inherent in the original data. To the knowledge of the ACPF Hub, there is no other source for field boundary data for IL. If you look at aerial imagery and see agricultural fields or pastures that you would like to include in your analysis and there is not a current field boundary polygon, you will have to create that feature. Examining the suitability of the field boundary dataset before running a HUC 12 through the toolbox is necessary to fix the situation you are seeing.  If you choose to add fields/polygons to the HUC datasets, before you run tools that use those data, be sure to run the Utility u3 to update the field boundary IDs and add the updateYr to those new polygons to reflect the year of imagery you use to determine boundaries.  The tool will also recalculate the landuse lookup table to include the new polygons.
