Do you use ESRI’s basemaps?  Have you ever seen a problem in one, like an incorrect street name or place name?  Or maybe an issue with some imagery?  If so, ESRI has some web maps setup for you to “Edit” and markup for feedback of issues or errors.  The feedback is received by the ArcGIS Online team to evaluate for one of their updates.

Here are a few basemaps that you can add your feedback on:

Street Map Feedback

Topographic Map Feedback

Imagery Map Feedback

Vector Basemap Feedback

Use them to clean up any inconsistencies in your jurisdictions!
