Ozark National Forest Service Stands (polygon)

Ozark - St. Francis National Forests stand inventory data for vegetation, maintained in polygon format. Polygon boundaries that provide areas to be rotated for entry of timber inventory and management. Stand is defined as a spatially continuous group of trees and associated vegetation having similar structures and growing under similar soil and climatic conditions.Vegetation polygons support Forest Service vegetation data management and analysis. Vegetation data is critical in support of land management; whether it be for wildlife habitat analysis, fire and fuels management, watershed management, or timber production. A vegetation polygon is a logical sampling unit; a logical area of land on which to describe vegetation conditions. Over time, data is collected for some or all of these polygons. Data such as canopy cover or forest type may be derived for each polygon via satellite image processing or photo interpretation. Field crews may be sent to a selection of polygons to collect detailed data where individual trees are measured or down woody material is measured along transects. The amount and currency of data describing each vegetation polygon varies widely since it is cost-prohibitive to maintain detailed and current data for all polygons at any point in time. Data for some polygons may be more than 10 years old, while data for other polygons may have been collected yesterday. Typically where active project work or landscape analysis is occurring, better data is available since there is a need for good data for that area at that point in time. Data for polygons within the NRIS_VegPoly feature class is changing on a daily basis as data is updated by Forest Service staff. This feature class is a "working" dataset; that is, it supports day-to-day Forest Service land management.

Runway 1999 (line)

Data available online through the Arkansas Spatial Data Infrastructure (ASDI) at http://gis.arkansas.gov. The subject file represents the Arkansas portion of a geographic data set of runways in the United States and US territories containing information on the physical characteristics of the runways. The 8550 runways in the data set are supposed to include all of the runways associated with the 6734 airports in the companion airport data set Airports, 1998 (BTS). Data were obtained from the Federal Aviation Administration's (FAA) National Flight Data Center (NFDC) 5010 landing facilities data (January 1999). Landing facilities in this database consist of those identified in the NFDC 5010 database to be either publicly owned, or privately owned but open to the public, or owned by the U.S. military. The following landing facilities have been excluded: private landing facilities not open to the public, glider ports and ultra light landing facilities, as well as landing facilities that do not have a current LOCID assigned to them. Horizontal positional accuracy is based on coordinate data provided in the NFDC 5010 database. These coordinate data identify the approximate location of the Airport Reference Point (ARP) as reported by the landing facility on the NFDC 5010 form. According to NFDC guidelines, the location of the ARP should be reported to a horizontal accuracy of one arc second of latitude and longitude. However, the accuracy of these reported coordinates are not verified by FAA. The scale is unknown.

Points On System 100 Feet

The Off-System are routes on AHTD's Linear Referencing System (LRS) that for the most part are not part of the State Highway System but qualify for Federal Aid because they are on the Functional Class System. The AHTD identifies these routes on the LRS because they are required to report condition, events, assets, etc. on them. The majority of the routes are county routes and city streets. However, we also put Frontage Roads, Ramps, Institutional Drives (College Campus Roads, Hospital Roads, Airport Roads and State Park Roads) on the On-System layer.

Location.ZIPCODE_TABULATION_CENSUS_2013

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. ZIP Code Tabulation Areas (ZCTAs) are approximate area representations of U.S. Postal Service (USPS) ZIP Code service areas that the Census Bureau creates to present statistical data for each decennial census. The Census Bureau delineates ZCTA boundaries for the United States, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and the U.S. Virgin Islands once each decade following the decennial census. Data users should not use ZCTAs to identify the official USPS ZIP Code for mail delivery. The USPS makes periodic changes to ZIP Codes to support more efficient mail delivery. The Census Bureau uses tabulation blocks as the basis for defining each ZCTA. Tabulation blocks are assigned to a ZCTA based on the most frequently occurring ZIP Code for the addresses contained within that block. The most frequently occurring ZIP Code also becomes the five-digit numeric code of the ZCTA. These codes may contain leading zeros. Blocks that do not contain addresses but are surrounded by a single ZCTA (enclaves) are assigned to the surrounding ZCTA. Because the Census Bureau only uses the most frequently occurring ZIP Code to assign blocks, a ZCTA may not exist for every USPS ZIP Code. Some ZIP Codes may not have a matching ZCTA because too few addresses were associated with the specific ZIP Code or the ZIP Code was not the most frequently occurring ZIP Code within any of the blocks where it exists. The ZCTA boundaries in this release are those delineated following the 2010 Census.

The HGM approach was used in the creation of this data.Section 404 of the Clean Water Act directs the U.S. Army Corps of Engineers to administer a regulatory program for permitting the discharge of dredged or fill material in âwaters of the United States.â As part of the permit review process, the impact of discharging dredged or fill material on wetland functions must be assessed. In 1996, a National Action Plan to implement the Hydrogeomorphic Approach for developing Regional Guidebooks to assess wetland functions was published. The Hydrogeomorphic Approach is a collection of concepts and methods for developing functional indices and subsequently using them to assess the capacity of a wetland to perform functions relative to similar wetlands in a region. This report, one of a series of Regional Guidebooks that will be published in accordance with the National Action Plan, applies the Hydrogeomorphic Approach to wetland and riparian forests in the Arkansas Valley Region of Arkansas in a planning and ecosystem restoration context.

asdi.IMAGERY.NHAP_AR_QUAD_INDEX

This metadata describes the 81cm pixel resolution, historical (1980s) orthophotography produced for the U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) by the Center for Advanced Spatial Technologies (CAST), University of Arkansas. The ortho product provided is 3-band CIR, 8-bit per pixel and delivered in USGS 24k quad tiles (with a 100m buffer) as uncompressed GeoTIFF and compressed (10:1 using JPEG compression) GeoTIFF formats. This orthophotography is published in Universal Transverse Mercator Zone 15N, NAD83, meters, EPSG:26915. Source aerial photography was collected between 1980 and 1986 at a scale of 1:58,000 as part of the National High Altitude Photography (NHAP) program. More information about NHAP can be found at https://doi.org/10.5066/F7M043NG. Mixing photography from multiple dates was avoided as much as possible, therefore each tile is an orthomosaic composed of at least three overlapping aerial photos that were captured on one date (likely seconds apart). However, systematic differences in radiometry do exist between some adjacent orthophotos and between adjacent flight lines due to different conditions at the time of exposure (date of capture, flight direction, sun angle). No color or histogram matching was attempted and pixel values within these orthomosaics closely match the original pixel values captured during the scanning process.

Census Block Group 2005 First Edition (polygon)

The 2005 First Edition TIGER/Line files are an extract of selected geographic and cartographic information from the Census TIGER database. The geographic coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on the latest available governmental unit boundaries. The Census TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can be combined to cover the whole Nation. The 2005 First Edition TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries. The files contain information distributed over a series of record types for the spatial objects of a county. There are 19 record types, including the basic data record, the shape coordinate points, and geographic codes that can be used with appropriate software to prepare maps. Other geographic information contained in the files includes attributes such as feature identifiers/census feature class codes (CFCC) used to differentiate feature types, address ranges and ZIP Codes, codes for legal and statistical entities, latitude/longitude coordinates of linear and point features, landmark point features, area landmarks, and area boundaries.

Pulaski County 2010 - 2011 2 foot contours

This dataset consists of 2 foot interval contour lines with ground elvation contained in the 3D geometry attribute data. Fugro EarthData, Inc collected LiDAR for approximately 714 square miles at 1.0 points per square meter (1.0m GSD) for the FEMA project area the southeast portion of Pulaski County in 2010, and most of the remaining part of the County in 2011. The extreme northeastern part of Pulaski County (essentially north of Highay 89 was not collected. Dewberry used proprietary procedures to classify the LAS according to project specifications: 1-Unclassified, 2-Ground, 7-Noise, 9-Water, 10-Ignored Ground, 11-Withheld Points. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the 199 tiles (10,000 ft x 10,000 ft) that cover the project area. The contour data was generated from the bare earth DEM and DTM data.

asdi.STRUCTURE.DAMS_ANRC

Locations of Dams in Arkansas (updated January 2018) as provided to the Arkansas Natural Resources Commission by the Army Corp of Engineers. This database represents a collection of permitted dam locations in Arkansas. Dams within the State of Arkansas fall under a permit process established under Arkansas Code 15-22-201. All dams with height of 25 or more feet and containing 50 acre-feet or more of storage at normal pool must have a valid construction and operation permit from the Commission, unless they are owned by the United States Government. If smaller dams pose a threat to life or property, they may also require regulation by the State based on a petition by downstream landowners and results of a public hearing. Dams are defined as: Any barrier, including one for flood detention, designed to impound liquid volumes. This shall not include highway, railroad or other roadway embankments, including low water crossings that may temporarily detain floodwater, levees designed to prevent inundation by floodwater, or closed dikes to temporarily impound liquids in the event of emergencies and those barriers not exempt by Sections 701.3 or 701.4 of TITLE VII RULES GOVERNING DESIGN AND OPERATION OF DAMS [As Restated October, 1993]
