Interactive Map

The interactive map is a step up in sophistication from the land cover, riparian zone and impervious cover map galleries on this website. It is designed to let you visualize and share all the datasets that are part of the Long Island Sound Watershed's Changing Landscape. If you are ready for even more sophistication (and more work on your end), visit the Map Services page.

Zoom In and Out

The zoom control are in the upper left corner of the map. The + zooms in and the - zooms out.


Turn Layers On and Off

Interactive Map Change Layers menuThe Layers drop-down menu on the top bar is the key to turning layers on and off. Clicking on Layers opens the Layer List of all layers that exist in the map. What is a layer? If the box next to the layer name is unchecked, Layer is Offthen the layer is "off" or not visible. If the box next to the layer name is checked, Layer is Onthen the layer is "on" or visible. You can turn multiple layers on at one time, but remember that they stack like pancakes. The layers on the top of the list are drawn on top of those underneath it. It is quite for layers lower on the list to be blocked, or hidden, by those on top.

Change Basemap

Basemap ButtonThe basemap is the layer at the very bottom, or underneath, all others. In this case, basemaps are created and served by the software company, Esri. Click on the Basemap to see all 12 (yep, 12!) choices, including the Topographic base map, the National Geographic base map and the Bing Maps Aerial Imagery base map. If you need something plain and simple, the Light Gray Canvas is the best. Have fun!
