Survey Protocol
ENVS 436-536 Fall 2014. Instructor: Fred Watson.
1. Navigate to site using GPS coordinates
a. If you can’t reach the site, and can’t clearly see exactly where the site is and what’s there, then abandon
the site and move on to your next assigned site. If you can’t reach it, but you can see exactly what’s
there, establish nearby waypoints that you can reach, and sketch the rest.
2. Consider the ‘site’ to be a 15x15m area centered on the GPS coordinates; i.e. a Landsat Pan-band pixel
Take a georeferenced photo of the site with a GPS-enabled camera
3. Determine the actual LC class of the site using this dichotomous key:
(Go down the questions from top to bottom and choose the first answer that applies)
(Note that 10% of a 15×15 m pixel is about 4.7×4.7 m, or 16×16 feet;
and 25% of 15×15 m pixel is about 7.5×7.5 m, or about 25×25 feet)
a. Water (deeper than 30 cm)  25% cover
i. Water
b. Structures  25% cover
i. Urban
c. Asphalt, gravel, or concrete  25% cover
i. Bare unnatural
d. Tree canopy cover  10% cover
i. Woodland / forest
e. Shrub canopy cover  10% cover
i. Shrubland
f. Ice plant cover  10% cover
i. Ice plant
g. Crops or lawn cover  25% cover
i. Crops / lawn
h. Grass or other herbaceous vegetation  10% cover
i. Grassland
i. Bare natural
4. Walk a polygon around the site encompassing only land that has the same LC class as the site.
a. Before you start, save your current GPS track and start a new one
b. The polygon should ideally be about 300-400 m in circumference
(i.e. about 90-130 m in diameter, or about 45-65 m in radius)
c. The site should ideally be in the center of the polygon; and ideally not at the edge
d. After you’re done, save the GPS track
