ID
30101292C045050000 is a section of a nine-digit geospatial quadrant identification (QUAD ID). The nine-digit quadrant ID is used to help identify a two-dimensional area within a specific geographic region. The first two digits, “30”, refer to the QUAD Level, or “quadrant level,” which is usually a 1:24,000-scale map. The next two digits, “10”, refer to the core, or most detailed area within the quadrant. The fourth digit, “2”, refers to the coverage type, which could refer to city, county, or state boundaries, depending on the context. The next six digits, “292C04”, refer to a specific quadrant within the core. The final four digits, “505”, represent an exact area within the selected quadrant. The last digit of a QUAD ID, “0”, is reserved for future use and not used in the current version of the system.
