How to Merge Fill-in data to a SWAT MAP

The user should be comfortable with the layer prep process before trying this process.

1. Folder Prep
   1. In ADMS, Create folders to move original data into.
      1. MapsData: Move everything thing into a folder named "OriginalMaps".
      2. Mobile app: leave existing folders as is, rename the sample point data file "SampleOriginal", Rename the Chosen SWAT MAP with an "Original" prefix and delete the rest of the kmzs and elevation file.
      3. ModData: Move everything thing into a folder named "OriginalMods".
      4. PointData: Leave as is.
      5. Zone Maps: Move everything thing into a folder named "OriginalZoneMaps".
2. Export and check data
   1. Export the EC and RTK data from the SWAT MAPS module.
   2. Open the new point data file and the mapping outline layer to make sure the mapper didn't miss mapping any areas.
3. Adjust new data
   1. Turn on the new and original EC point data with an EC grid layer.
   2. Zoom into an area where the data points overlap and EC is low.
      1. If the point data is missing or corrupted then create grd files with the new point data and merge them with the original grd files.
      2. Pixelize the merged files to smooth out the transitions.
      3. Continue with step 6: Create new boundary.
   3. Turn on point data labels so both layers are a different colored.
   4. Where the point data overlaps, Adjust the values (shallow and deep) of the new data to match the original data with the tool Preform a math operation on a column.

1. Merge point data files
   1. Apply any offset mods to new data that was just adjusted.
   2. Clear the map then open the new and original EC point data layers.
   3. Right click on one of the point data layers > click Utilities > click Merge All Visible Shp's
      1. Data columns (EC Shallow, EC Deep, RTK) need to have the exact same name for the layers to merge properly.
   4. Save the merged file and name it "ECMergedYear".
   5. Repeat for the RTK layers.
   6. Create a grid of the merged layer and observe it for lines that show any shifts between the new and old data. Skip step 5 if there are no shifting issues. Pixelize data as usual.
2. Address data shifting issue if present
   1. Overlay the new point data with the merged EC grd. Highlight and delete points where there is shifting. This might only be over lines where the SWAT Box was navigating across the field from one fill-in area to another.
   2. You may need to delete every point were the data overlaps. This is required when the soil EC has changed since it was last mapped, causing a discrepancy where the data overlaps. In this case, make a copy of the original data and delete from this. You want to keep the new data in areas that overlap because it is most accurate to the current field conductivity conditions.
   3. Create Grids and Pixelize.
   4. The RTK data shouldn’t have any shifting issues.
3. Create new boundary: This process is different depending on the scenario.
   1. Mapper Re-mapped the entire boundary for the field: Simply export the new boundary and use it.
   2. Fill-in is small/simple: Make a copy of the original boundary and manually edit using the imagery and merged point data as a guide.
   3. Fill-in is large/complicated:  generate a new boundary from point data
      1. Right click merged point data file > click Generate Boundary > set Smoothness and Subset all the way to the left > click Run Boundary > click Ok
      2. Right click generated boundary > Reset drawing properties
      3. Manually clean-up/smooth generated boundary to line up with point data.
      4. Right click generated boundary > click Shape Tools > click Buffer > set distance to 15
      5. Make a file of original internal boundaries if applicable:
         1. Make a copy of the original boundary
         2. Decompose
         3. Delete outside boundaries
         4. Save
      6. Manually create any new internal boundaries if applicable.
         1. Create a boundary shape file
         2. Draw internal boundaries right along point data. The Trace function in the drawing window can make this easier.
         3. Once internal boundaries are drawn, right click shape file > click Shape Tools > click Buffer > set distance to -15
      7. Clear map
      8. Open the generated external boundary, the original internal boundary and the manually drawn internal boundary.
      9. Make sure each layer is decomposed.
      10. Right click on one of the point data layers > click Utilities > click Merge All Visible Shp's.
      11. Save this new layer and make it into a Poly-polygon. 
      12. Name the file "Boundary-1".
4. Clip Merged EC and RTK layers to the new boundary.
5. Re-generate the SWAT MAPS using the new merged data. In the SWAT MAP Module, be sure to set the Acres to New so the client isn't billed again for the existing acres. If this step is missed re-run the Layer prep with the acres set to custom and manually set the value to the difference between the original and new acres calculated from ADMS.
