During the application process, you'll be able to select your area of interest by selecting your country, state, and county through the dropdown lists. The boundaries are based on boundaries available in OpenStreetMap and have been pre-built into our system. At this time, county is the most granular administrative level we are able to provide, and we're unable to provide changes or edits to these boundaries for the Dashboard page.
If you don't see your area of interest in the dropdown list in the application page, select the next largest boundary for your region. But stay tuned for some exciting updates about custom boundary creation!
