Batch Polygon Tracing

The following series of pages will guide you through uploading and tracing polygons in a database. Step-by-step documentation for how to upload and process a database is available here.



In a nutshell, to upload a database and create polygons you will need to perform four steps:

  • Step 1 - Upload your data files and validate that we can open and read them
  • Step 2 - Choose which data in your files you want to process
  • Step 3 - Identify the fields of your data so we know which column is what
  • Step 4 - Start tracing polygons
