Enabling Better Decision Making

Having an easy-to-use and transparent platform to share spatial information early in the planning process allows users to identify potential conflicts so that they can then be avoided or addressed. Spatial data are essential for many planning activities, including siting of renewable energy projects, designing restoration projects, and helping communities identify areas vulnerable to sea level rise, flooding, and erosion. It also allows users to explore where popular recreational activities take place, view land and water trails, and learn more about our working waterfronts. Maryland’s Coastal Resiliency Assessment data is also available.

Data & Tools

In addition to coastal datasets, online tools for the Coastal Atlas have been developed to support better decision-making and help concerned citizens address specific coastal issues. Users can use the measuring tool to measure shoreline fetch, the draw tool to draw a box around a specific area, or the identify tool to get more information about the data. Users can also work with us to generate targeting queries that help you narrow your focus area.
