200m x 200m grids on 2 images

Discussion created by hendrix27 on Oct 19, 2011
i want to estimate changes in tree quantity. one is from the 60s and one is recent.
i wanna put a grid layer over both in order to estimate trees visually.
the rapid land cover mapper (dot system) tool from USGS will be used.

but it is a bit more sophisticated. the grids shall be within transects from a central point (village).
the transects are of 4 km x 0,5 km size and should go in all directions( north, south, west, east).
any suggestion is welcome! i am completely new to this
