Interactive SRAs and NAs(Parcel Level Information) The Interactive Proposed SRAs and NAs maps display the proposed State Resource Areas and Natural Areas over aerial photographs, and allow zooming into the level of individual parcels. The map viewer first opens to a state outline without any details. To see the roads, proposed SRAs and NAs, and parcel boundaries, you must zoom in. To do this, press the Zoom In button (magnifying glass with + sign) on the toolbar to the left. Then click and drag the mouse on the map to draw a rectangle around the location of interest. Refine the view by zooming in and out and by using the Pan button (hand) to move east/west and north/south. When you are satisfied with the view, check the box for Statewide 2002 Photo in the Layer list on the right. To display the map legend that explains colors and symbols, press the Toggle Between Legend and Layer List button (upper left on the toolbar). Note that due to the large file size of the aerial photos, you can zoom and pan faster if you turn the aerial photo layer off before you move around, then turn it on after you’ve reached your destination.
