Map_OCWater2018_Clip_SmoothP
This is an updated version of Map_OCWaters2018 published in 2020. The water bodies here are those held by artificial facilities such as swimming pools, ponds in parks, and water recycling facilities. The first version data had been detected from 4-band aerial images by image processing algorithms and geoprocessing methods. This version has been optimized in the shapes by polygon smoothing, and a field of "Surface height" has been added based on DEM of Orange County.
