Restated, how do I convert arc degrees to meters? For example, I have an elevation data raster that has the following metadata:
WEST LONGITUDE=64.97798789° E
NORTH LATITUDE=33.02003415° N
EAST LONGITUDE=66.03338707° E
SOUTH LATITUDE=31.98030163° N
PROJ_DESC=Geographic (Latitude/Longitude) / WGS84 / arc degrees
PROJ_DATUM=WGS84
PROJ_UNITS=arc degrees
EPSG_CODE=4326
NUM COLUMNS=9001
NUM ROWS=9001
PIXEL WIDTH=0.0001111 arc degrees
PIXEL HEIGHT=0.0001111 arc degrees
I can compute by hand the pixel width in arc degrees as follows:
(EAST LONGITUDE - WEST LONGITUDE) / NUM COLUMNS
Similarly, I can compute by hand the pixel height in arc degrees as follows:
(NORTH LATITUDE - SOUTH LATITUDE) / NUM ROWS
My question is how to compute the pixel width and height in meters.
