This dataset includes the mapping of wheat and maize crops in the Metropolitan Region of Santiago (Chile), together with the field validation points used to verify the accuracy of these maps. Both datasets were produced as part of the study "Five Centuries of Urban Growth: Impacts on Food Security and Soil Functionality." The maps represent the spatial distribution of both crops during the period contemporary to the 2007 Agricultural Census. They are provided as raster files in UTM WGS84 projection (EPSG:32719), where pixels with a value of 1 indicate crop presence. The dataset was created to address the lack of publicly available information on crop locations, aiming to estimate agricultural productivity and the loss of cultivable soils due to urban expansion. The delineation of agricultural areas was first based on the "annual crops and grasslands" category from the Land Cover Map 2009 (Galleguillos et al., 2024). On this basis, a temporal analysis of the Normalized Difference Vegetation Index (NDVI) was applied using Landsat 5 surface reflectance imagery processed in Google Earth Engine, considering three periods: (T1) February–April 2009, (T2) September–November 2009, and (T3) December 2009–February 2010. Percentage changes in NDVI between periods (20%, 30%, and 40%) were used to identify the characteristic phenological behaviors of wheat (increase T1–T2 and decrease T3) and maize (increase T2–T3). In addition, topographic filters (slope <10% for wheat and <5% for maize) and a GLCM-based textural analysis on NDVI images were applied to minimize confusion with natural vegetation.The dataset also includes two shapefiles containing 175 field points (159 accessible), projected in UTM WGS84 (EPSG:32719). These points correspond to the areas visited during two field campaigns conducted on October 8 and 19, 2025, where crops or their rotations were verified through direct observation and interviews with local farmers
