Abstract

These shapefiles of lakes, streams, wetlands, river bottoms, and the Mississippi River represent the hydrological landscape of Minneapolis and St. Paul as recorded in the original public land survey conducted between 1848 and 1858. The features were digitized from scanned, georeferenced 1:24000 maps during the 2017 Faculty Research Sprint held at the University of Minnesota. Many streams and other hydrologic features that were present in the Twin Cities at the time of the original land survey were channelized, covered, or filled during the late 1800's. These features, however, still function as water conduits within the hydrology systems of urban water and have immense importance to the water regime in the Twin Cities. This data was generated as part of a larger "Lost Waters" research project - aiming to create a visible, physical representation of these waters in the current urban landscape.

Description

Scanned maps from the original public land survey of the Twin Cities were downloaded from Minnesota IT Services Geospatial Information Office (http://www.mngeo.state.mn.us/chouse/GLO/ ). These georeferenced images of 1:24000 maps were provided in the NAD 1983 geographic coordinate system (EPSG:4269). Researchers and staff from the University of Minnesota digitzed features related to streams, lakes, and wetlands in ArcMap using the "Create Features" tool in the editor toolbar. The digitized layers for each type of water feature were merged together, converted into shapefiles, and reprojected into the WGS 1984 Web Mercator Auxiliary Sphere projection (EPSG: 3857).
