Abstract
Abstract
Land evaluation is essential for assessing environmental limitations that inhibit higher yield and productivity in food crops, including rice. This research aimed to determine the suitable lands for sustainable rice production in the northern part of the Yogyakarta Special Region using phenological datasets from remote sensing and geospatial datasets of soil-plant biophysical properties. Sentinel-2 satellite images were processed to obtain layers for land use and land cover (LULC) and the normalized difference vegetation index (NDVI). Validation used statistical data of rice productivity from the Agricultural and Fisheries Agency of Sleman Regency. Vector and raster layers of maps were processed in ArcGIS 10.2.1 software. Finally, suitability classes were determined using a weighted overlay of spatial analysis based on reclassified raster layers of all parameters and the results from the multicriteria analysis.
