Archive of Census Related Products (ACRP): 1992 Boundary Files

The 1992 Boundary Files portion of the Archive of Census Related Products (ACRP) consists of 1992 boundary data from the U.S. Census Bureau's Topologically Integrated Geographic Encoding and Referencing (TIGER) system. The data have been processed to create the state boundary files for county, county subdivision (mcd), place, 1990 tract/block numbering area, blockgroup, and 1980 tract and mcd's (if available). The tract and blockgroup files are grouped by MSA (Metropolitan Statistical Area) and CMSA (Consolidated Metropolitan Statistical Area). County boundary files have also been created for each census block, distinguished by its unique POLygon IDentification (POLID) field, matching the corresponding POLID in the 1990 Summary Tape File (STF) data. This portion of the ACRP is produced by the Center for International Earth Science Information Network (CIESIN).

数据集描述: 该数据集为《人口相关产品档案》（ACRP）中的1992年边界文件部分，包含美国人口普查局拓扑集成地理编码和参照系统（TIGER）的1992年边界数据。经过处理，已生成州界、县界、县下分区（mcd）、地方、1990年街区/区块编号区域、区块群以及1980年街区与mcd的边界文件（如有）。街区与区块群文件按大都市统计区（MSA）和合并大都市统计区（CMSA）进行分组。同时，为每个人口普查区块创建了县界文件，并通过其独特的多边形标识（POLID）字段进行区分，与1990年汇总录音文件（STF）数据中的对应POLID相匹配。此ACRP部分由国际地球科学信息网络中心（CIESIN）制作。
