The data were digitized in the late 1960s, early 1970s, and in 1984-85 from 7.5- and 15-minute USGS topographic quadrangles. Errors in the location of a given feature are dependent on the accuracy of the original maps and on the accuracy of digitizing. Estimates are that features have an average locational error of approximately plus/minus 100 feet. Some areas of the state have a locational error of approximately 600 feet.<\/span><\/p>

In areas of French colonization land grants, where PLSS sections were not actually surveyed, sections and section lines have been added (estimated).<\/span><\/p><\/div><\/div><\/div><\/div>", "extent":[[-1.0664245721460987E7,-9262916.544939015],[4394273.295510339,5278085.222189663]], "url":"https://gis.prairie.illinois.edu/arcgis/rest/services/Reference_Layers/PLSS_Public_Land_Survey_System/MapServer" }
