Estimation of crop extent using multi-temporal PALSAR data
Abstract : The aim of the approach proposed in this paper is to
determine a potential crop extent prior to the crop season, by
determining regions that might change in time vs. those that
surely do not change. We use multi-annual PALSAR-1 data
since in dry conditions, L-band HH/HV data have a potential
of distinguishing between bare soil and other classes. In
addition, a more accurate map can be reached with multitemporal
data than using a single date. We work on HH and
HV data sets separately and analyze the two outputs using
ground-truth information. In a final phase, we combine these
two outputs and compare the result with the ground-truth
too, to test the usefulness of fusing the HH/HV information.
This approach is the first step in our three-step procedure for
estimation of cultivated area in small plot agriculture in
Malawi. Validation results show that the proposed approach
is promising.
