Online Mapping Resources
It is important to look beyond your monitoring site and gain a broader understanding of your watershed. The chart and list below serve as a guide to user-friendly mapping applications that can help you delineate your watershed, identify potential and actual pollution sources, and explore historical and present land uses. These helpful tools can also be used to complete the annual Watershed Assessment .
To learn more about these mapping applications, watch the Online Mapping Webinar posted on the AAS YouTube page.
