    Description

    This coverage contains the section lines for the Public Land Survey System (PLSS). These lines form polygons which are labelled for PLSS township, range and section number. Coordinates were digitized from U. S. Geological Survey 7.5' topographic maps (paper copies) using a digitizing program developed in-house by the Geological Survey Bureau, Iowa DNR. The digitizing tablet accuracy was 1/50 inch. Section lines from individual quads were combined and edited using PC Arc/Info.

    Description

    This Digital Elevation Model (DEM) of the bedrock surface elevation in Iowa was compiled using all available data, principally information from GEOSAM, supplemented with well and boring information from the Iowa DOT, exposure reports from Iowa Geological & Water Survey reports and files, and the Department of Soil Conservation county soil maps for Iowa. The soil maps were especially valuable, since they identified soils that encountered bedrock within the soil horizon, and less dependably also spot-located rock exposures. A 50 foot contour interval was chosen for the map because it was considered to best represent the accuracy of the well data, allowed for fairly good representation of the bedrock surface in areas with limited well control, and was mappable in high relief areas (the contours packed so close together that it precluded mapping or forced the software to snap-join contours). The 50 foot contour interval also allowed areas where bedrock was present within the soil horizon (2-3 feet) to be treated as areas of exposures. In these areas the bedrock elevation was mapped as only slightly below the surface elevation, so contours on the 7«' topographic maps were closely followed in mapping the bedrock elevation. Consequently, on the completed map of bedrock elevation, these areas display much more contorted and crenulated contour lines than the areas where only drill control was utilized.

    Description

    U.S. Geological Survey (USGS) scientists conducted field data collection efforts between October 25th and 31st, 2020 at several sites in eastern Iowa using high accuracy surveying technologies. The work was initiated as an effort to validate commercially acquired topographic light detection and ranging (lidar) data that was collected between December 7th, 2019 and November 19th, 2020 using wide area mapping lidar systems for the USGS 3D Elevation Program (3DEP). The goal was to compare and validate the airborne lidar data to topographic, structural, and infrastructural data collected through more traditional means (e.g., Global Navigational Satellite System (GNSS) surveying). Evaluating these data will provide valuable information on the performance of wide area topographic lidar mapping capabilities that are becoming more widely used in 3DEP. The airborne lidar was collected to support the U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) Hig ...

    Description

    This dataset provides the geographic names data for Iowa. All names data products are extracted from the Geographic Names Information System (GNIS), the Federal Government's repository of official geographic names. The GNIS contains the federally recognized name of each feature and defines its location by State, county, USGS topographic map, and geographic coordinates. GNIS also lists variant names, which are non-official names by which a feature is or was known. Other attributes include unique Feature ID and feature class. Feature classes under the purview of the U.S. Board on Geographic Names include natural features, unincorporated populated places, canals, channels, reservoirs, and more.
