Welcome to DEC Web Maps
In this map gallery, you will find links to the DEC's public interactive web maps. Each map is focused on a program area or major incident. Click on a thumbnail image or map title to go to the map's information page, then open the map. More information on how to use the web maps can be found here.
The majority of our maps have been developed in ArcGIS.com and can be opened in your web browser with the ArcGIS.com viewer or ArcGIS Explorer Online. They can also be opened in ArcGIS Desktop 10 or with the free ArcGIS app for iOS, Android and Windows Phone devices. Air Quality web maps are custom applications that can be opened in your web browser from the map's information page.
Click on one of the thumbnail pictures of the map you wish to see. This will take you to the description page for that map. Read the details about that map and then select the ArcGIS.com map viewer by clicking the Open button under the thumbnail image. You can also just click the image and go directly to the ArcGIS.com map viewer for that map. The web map will open in the default view as set for that map.
Additional details on how to navigate a map and use the various tools of the ArcGIS.com map viewer can be found in the ArcGIS.com help documentation here.
