Vector polygon map data of city limits from Las Vegas, Nevada containing 87 features.

City limits GIS (Geographic Information System) data provides valuable information about the boundaries of a city, which is crucial for various planning and decision-making processes. Urban planners and government officials use this data to understand the extent of their jurisdiction and to make informed decisions regarding zoning, land use, and infrastructure development within the city limits.

By overlaying city limits GIS data with other layers such as population density, land parcels, and environmental features, planners can analyze spatial patterns and identify areas for growth, conservation, or redevelopment. This data also aids in emergency management by defining the areas of responsibility for different emergency services, helping to streamline response efforts during crises..

Download .zipThis map was derived from the Clark County Soil Survey using the Universal Soil Loss Equation to calculate estimated erosion rates from soil with no till management systems. Land use data from 1979 aerial photography was utilized in the analysis to exlude all lands except cropland, pasture, and shrub and brush rangeland. Soil erosion rates were then compared to "T", the soil loss rate which can be allowed and still maintain long term productivity.

Factors combined by the universal soil loss equation include: rainfall factor(R), ersosion factor ("K"), slope length and steepness factor (L-S) and the cropping factor (C). For this analysis a rainfall factor of 150 was used and a cropping factor of .09. The slope length and steepness factor was varied by soil mapping unit and was provided by the Clark County Office of the Natural Resources Conservation Service.

Soils used in this analysis were digitized from the paper original soil survey sheets using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The resulting county file has subsequently been converted to Arc/Info format.

The user should bear in mind that this coverage is only an approximation of the soil survey and should not be used for site specific analysis.

Additional details of the digitizing process are available upon request.

Download .zipThis map was derived by combining the Clark County Soil Survey with other geologic, land use and environmental data for the county. It was developed as a general planning tool and should not be used to substitute for a detailed site analysis.The analysis was conducted by combining the following variables in order of increasing severity: 1. Slope 2. Texture 3. Bedrock 4. Glacial Geology 5. Flood Problem Areas 6. Ground-Water Availability 7. Drainage 7. Permeability 8. Depth to Seasonal High Water Table 9. Land Use

Soils and other variable used in this analysis were digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). These files were in a raster format. The final analysis was subsequently converted from raster to ARC/INFO format.

1:24,000 scale Geologic Map of the Nelson Quadrangle, Clark County, Nevada. Nevada Bureau of Mines Map 134. Detailed Geologic Mapping By Jame s E . Faulds, John W. Bell, and Eric L. Olson in 2002. Field work done 1999. Map includes two cross sections and 42 geologic units. The quadrangle includes part of the Highland range, Eldorado Valley, and Piute Valley. It contains excellent exposures of early to middle Miocene volcanic and sedimentary rocks, the upper part of the ~16.6 Ma Searchlight. Mining district. The Miocene section rests nonconformably on Early Proterozoic gneiss. As a result of the middle Miocene extension, Tertiary strata are moderately to steeply tilted and cut by complex arrays of normal faults. Flat-lying Quaternary alluvial-fan deposits dominate Eldorado and Piute Valleys and onlap tilted Miocene strata in the Highland Range. The GIS work was in support of the U.S. Geological Survey COGEOMAP program.

This data release supports the U.S. Geological Survey Scientific Investigation Map (SIM) by Clark and others (2020) by documenting the data used to create the geologic maps and describe geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers for a 442 square-mile area in northern Medina County in south Texas. The karstic Edwards and Trinity aquifers that are the subject of the SIM by Clark and others (2020) are classified as major sources of water in south-central Texas by the Texas Water Development Board (George and others, 2011). The geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers largely control groundwater-flow paths and storage in northern Medina County (Kuniasky and Ardis, 2004). The data provided in this data release and the detailed maps and descriptions of the geologic framework and hydrostratigraphy in Clark and others (2020) are intended to help provide water managers information that is useful for effectively managing available groundwater resources in the study area. These digital data accompany Clark, A.K., Morris, R.E., and Pedraza, D.E., 2020, Geologic framework and hydrostratigraphy of the Edwards and Trinity aquifers within northern Medina County, Texas: U.S. Geological Survey Scientific Investigations Map 3461, 13 p. pamphlet, 1 pl., scale 1:24,000, https://doi.org/10.3133/sim3461.

Fire District Map Pages - Map pages represent square mile rectangles covering Clark County, southern Cowlitz County and western Skamania County. They are used by fire agencies as map extents for the map books they may carry in their vehicles. Map pages are loosely based on Public Land Survey System sections (square miles), and the unique four-digit code for each map page is based on the township, range, and section numbers. However, they should not be used as a survey or legal description reference. Map pages are also a component of CRESA's Public Alert Grid map.See Clark County Metadata Data source: ..\FGDB\dw_PubSafety.gdb\MapPages

The GIS work was in support of the U. S. Geological Survey COGEOMAP program. The Geodatabase specifies feature datasets and feature classes, together with feature attributes, subtypes and domains, suitable for the printed geologic map. In addition to basic geology (lithology, contacts and faults, etc.), the maps may include metamorphic overprints, cross sections, and explanatory legend graphics such as correlation charts, used to supplement columnar legends. The Geologic Map of the Meadview North 7.5' Quadrangle in Mohave County, Arizona and Clark County, Nevada 1:24,000-scale is available for download online in Portable Document Format. Field work was supported by an EDMAP grant from the U.S. Geological Survey (Copperative agreement 1434-HQ-97-AG- 07146) and National Science Foundation grant EAR99-10977 awarded to Faulds. The U.S. Geological Survey also provided a field vehicle and funds for digitizing and publication of the map, for which we thank Gary Dixon and Peter Rowley. The National Park Service at Lake Mead National Recreation Area kindly provided boat access into some relatively inaccessible areas. The Meadview North Quadrangle lies within the northeasternmost part of the Colorado River extensional corridor (Howard and John, 1987; Faulds and others, 1990), which is a 70 to 100-km wide region of moderately to highly extended crust between the Colorado Plateau on the east and Spring Mountains on the west. The quadrangle contains much of the town of Meadview, Arizona, as well as the southern part of the Grand Wash trough (including much of the Gregg Basin), southern part of Wheeler Ridge, and northern end of a mountain range informally referred to as the Lost Basin Range (after Theodore and others, 1987).
