Contour basemap for the Omaha metropolitan area that includes Douglas & Sarpy Counties & surrounding portions of Dodge & Washington counties. Data was generated from the 2016 QL2 LiDAR project.Deliverables from the project can be downloaded from the project site:https://sarpy.maps.arcgis.com/apps/webappviewer/index.html?id=fd49c0b1d6414828b4034187ff63c6fe

Vector data from the basic DLM are generalized for the digital topographic maps and processed according to the ATKIS signature catalogue. The digital data can be submitted via download or on other media carriers. They are available in a maximum of 22 content levels (according to the technical regulations of the AdV) in three forms (individual levels, gray combination and color combination). It should be noted that a UTM grid is only output in the individual levels. The standard resolution is 200L/cm = 508dpi. The TK (ATKIS) presents a map issue with the same content as a printed map. The data is provided free of charge via automated processes or by self-extraction. When using the data, the license conditions must be observed.

description: The U.S. Geological Survey, in cooperation with The Central Nebraska Public Power and Irrigation District (CNPPD), conducted a study that used bathymetric and topographic surveying in conjunction with Geographical Information Systems techniques to determine the 2003 physical shape and storage capacity, as well as the change in storage capacity of Lake McConaughy that occurred over 62 years. By combining the bathymetric and topographic survey data, the 2003 surface area of Lake McConaughy was determined to be 30,413.0 acres, with a volume of 1,756,300 acre-feet at the lake conservation-pool elevation of 3,266.4 feet above North American Vertical Datum of 1988 (3,265.0 feet above CNPPD datum). To determine the changes in storage of Lake McConaughy, the 2003 survey Digital Elevation Model (DEM) was compared to a preconstruction DEM compiled from historical contour maps. This comparison showed an increase in elevation at the dam site due to the installation of Kingsley Dam. Immediately to the west of the Kingsley Dam is an area of decline where a borrow pit for Kingsley Dam was excavated. The comparison of the preconstruction survey to the 2003 survey also was used to estimate the gross storage capacity reduction that occurred between 1941 and 2002. The results of this comparison indicate a gross storage capacity reduction of approximately 42,372 acre-feet, at the lake conservation-pool elevation of 3,266.4 feet in NAVD 88 (3,265.0 feet in CNPPD datum). By comparing preconstruction and 2003 survey data and subtracting the Kingsley Dam and borrow pit, the total estimated net volume of sediment deposited from 1941 to 2003 was 53,347,124 cubic yards, at an annual average rate of 860,437 cubic yards per year. The approximate decrease in the net storage capacity from 1941 to 2003 was 33,066 acre-feet, at an annual average decrease of approximately 533 acre-feet per year, which resulted in a 1.8 percent decrease in storage capacity of Lake McConaughy. The lake accumulated most of the sediment in the original river channel and in the west end of the delta area on the upstream end of the lake.; abstract: The U.S. Geological Survey, in cooperation with The Central Nebraska Public Power and Irrigation District (CNPPD), conducted a study that used bathymetric and topographic surveying in conjunction with Geographical Information Systems techniques to determine the 2003 physical shape and storage capacity, as well as the change in storage capacity of Lake McConaughy that occurred over 62 years.
