USGS
Topographic Maps for Wetlands
Permit Applications
Using
the GRANIT Conservation Lands Viewer
Wetlands permit applications require a copy of the USGS
topographical map identifying the proposed project location. The
steps below describe how to use the GRANIT Conservation Lands Viewer to produce
maps for your town. To use this web-based, interactive mapping tool, you need
internet access and a web browser.
1.
Go
to website http://www.granitmap.sr.unh.edu.
2.
Below
the graphic in the middle of the page, click on “Click
here to go to the Viewer.”
3.
The
Map Display Settings in the upper right hand corner allow you to set a
background image for your map. Under “Image Backdrop” (drop down box) in the
right panel, click on the arrow and select “USGS Topo Quads.” (The image
will not appear immediately. It displays only when you have zoomed into a small
area, as described below.)
4.
In
the Utilities section in the upper right, click on “QUICK FIND.”
5.
In
the dialogue box, be sure the “Towns and Cities” button is highlighted in
the upper half box and find your town in the lower half box. Then click
“Find.” When the map appears behind the dialogue box, close the dialogue
box.
6.
Highlight
the “zoom in” icon (+ magnifier), and click on the map to get more detailed
views of the desired location until topographic lines appear (Scale 0 to 0.17
mi). You can also use this tool to describe a rectangle on your screen that will
become your viewing area.
7.
Highlight
the hand-shaped icon, and move the map to show the desired location.
8.
When
you have defined the image you want, you can print in two ways:
a.
To
print directly from the Viewer, click on “PRINT MAP” in the Utilities
section, name the map, and click “OK.” Print the map from the next box that
appears, and close it.
b.
To
insert the map into another document, click on “SAVE MAP” in the Utilities
section, click on the “Save this image” icon in the upper left corner. In
the Save Picture dialogue box, name the image (File name), define a path for its
storage (Save in), and click “Save.” Then open the desired document, insert
the image, add desired information, and print.
9.
Mark
the printed map as described in the wetland permit application.
