Workflow

Step A-1

A polygon shapefile is required. You may utilize the drawing tool within the CHART Scoping Tool to create a polygon shapefile, or you may import one.

Option 1. Skip to Part B and create a polygon shapefile within the tool as described in Part B

The shapefile must meet the following requirements to be used in the webtool:

1. A polygon shapefile
2. Contain an attribute named ReachName with a reach name entered
3. Contain an attribute named ReachCode with a reach code entered (5 characters or less)
4. Use the WGS 1984 coordinate system

Step A-2. Zip the shapefiles into a zipped folder for upload to the webtool

The shapefiles must be in a zipped folder format before uploading to the web tool.
