Label TextIn 1980, geological survey maps were still primarily based on surveys conducted by human surveyors on the ground, measuring and plotting distances between bench marks. This 1980 map of New Haven County incorporates information from aerial surveys, but only with the disclaimer that it has not been checked for accuracy. Such maps were the most accurate available in the 1970s, and they include a great deal of highly accurate information about the nature of the terrain. The introduction and spread of geographic information systems (GIS) had totallly transformed mapmaking by the end of the twentieth century, rendering old fashioned surveying methods virtually obsolete.
