ResumenA research group of the Institute for Sustainable Agriculture (CSIC, Cordoba, Spain) has developed an original procedure to classified crops from multitemporal remote sensing images, named CROPCLASS, to be used in agricultural and forestry scenes. The procedure is governed by registered CROPCLASS-2.0 software (1), which executes it semi-automatically. CROPCLASS procedure was patented (2) and it is described in a recent publication (3). Before developing CROPCLASS, the methodological approaches for cropping systems classification from remote sensing images widely varied among authors and required tremendous effort in image processing.
For each geographical area CROPCLASS consists of: 1) a definition of census parcels through vector files in the images; 2) the extraction of spectral bands (SB) and key vegetation index (VI) average values for each parcel and image; 3) the conformation of a matrix data (MD) of the extracted information; 4) the classification of MD through decision trees (DT), which provide a Structured Query Language (SQL) crop predictive model. The procedure is also based on preliminary land-use ground-truth work in a reduced number of parcels at least the first year of study. Crop SQL predictive models can be used to classify unidentified parcels land uses from the same area where the images were taken to generate the model.
CROPCLASS procedure meets additional advantages as follows. First, the census parcel is the unit for most administrative actions and CROPCLASS provide record for each census parcel. Second, administrations require a defined crop classification method, almost fully relying on remote sensed images automatically or semi-automatically executed, consistently reducing the ground-visit work as much as possible. Third, the predictive models for each crop/cropping system are likely to be used for the same area in subsequent years if the images were taken on about the same dates. This use is based on the true assumption that in each geographical area, the diversity of the crops and the crop calendar remain about the same throughout the years. The phenology or crop growth stages will approximately coincide, as the images were taken at about the same time in different years; therefore, the predictive models that were determined for one year with similar timings could tentatively be used in subsequent years.
Implementing the CROPCLASS procedure through conventional image processing is time consuming and requires computer language skills. The software CROPCLASS-2.0® can be implemented for any agricultural region semi-automatically, in an economically feasible manner. CROPCLASS-2.0 software is available at the digital repository (http://dx.doi.org/10.5061/dryad.j958j) only for research and academic purposes; furthermore its authorship should be mentioned with bold characters.
