SUMMARY</strong>\nThis is a dataset containing points representing the midpoint of each block in the City of San Francisco. This dataset is used for geomasking (e.g. removing an exact address and replacing it with a nearby anonymized point) and other anonymization tasks. \n\n<strong>B. HOW THE DATASET IS CREATED</strong>\nThis dataset was created by calculating the midpoint of each the street segment in the city (see <u><a href=\"https://data.sfgov.org/Geographic-Locations-and-Boundaries/Streets-Active-and-Retired/3psu-pn9h/about_data\">Streets - Active and Retired</a></u>) then returning the latitude and longitude of that midpoint. A street segment is a line between two intersections. Street midpoints are calculated for each side of the block. \n\n<strong>C. UPDATE PROCESS</strong>\nThis dataset is updated weekly.\n\n<strong>D. HOW TO USE THIS DATASET</strong>\nUse this dataset for geomasking and other anonymization workflows.\n\n<strong>E.
