In this study, we have developed a deep-learning-based framework for mapping urban land cover/use (buildings, roads, parking lots, forest, grassland/shrubland, agriculture, water bodies, barren, and others) at a very high-resolution of 1.0 meter. Applying the framework to the NAIP (National Agriculture Imagery Program) imagery, we have successfully produced land cover and land use maps for 20+ major cities in the United States. Our framework addresses several large-area mapping challenges, such as inconsistent viewing or solar elevation angles, and the lack of ample annotated datasets for model training. We are in the process of expanding the spatial coverage of our product and publishing it via an online platform.
