Land use based on the most current aerial photography. Centre Region Council of Governments completed the following municipalities... College, Ferguson, Harris, Halfmoon, Patton, and State College Borough, while the Centre County GIS and Planning Departments completed the remaining municipalities.

Originally created by the USDA / NRCS as a more accurate GIS soils layer. This has been modified, by the GIS Department, to include soils on some properties that cross over the County boundary. This layer is critical to the Ag Preservation Program in helping calculate values of properties that lie in multiple Counties.

Point Feature Class - It was originally captured as part of the 1995 Aerial Imagery project completed by Kimball. This layer has since been enhanced / modified and was incorporated in the bridge inventory project complete by the Centre County GIS Department, the MPO, and Centre Region COG.

Coordinate System: Pennsylvania State Plane South Zone 3702; U.S. Survey Foot

Development Notes: This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties. The soil map and data used in the SSURGO product were prepared by soil scientists as part of the National Cooperative Soil Survey

The Hydrology Feature Dataset contains photogrammetrically compiled water drainage features and structures including rivers, streams, drainage canals, locks, dams, lakes, ponds, reservoirs and mooring cells. Rivers, Lakes, Ponds, Reservoirs, Hidden Lakes, Reservoirs or Ponds: If greater than 25 feet and less than 30 feet wide, is captured as a double line stream. If greater than 30 feet wide it is captured as a river. Lakes are large standing bodies of water greater than 5 acres in size. Ponds are large standing bodies of water greater than 1 acre and less than 5 acres in size. Polygons are created from Stream edges and River Edges. The Ohio River, Monongahela River and Allegheny River are coded as Major Rivers. All other River and Stream polygons are coded as River. If a stream is less than 25 feet wide it is placed as a single line and coded as a Stream. Both sides of the stream are digitized and coded as a Stream for Streams whose width is greater than 25 feet. River edges are digitized and coded as River. A Drainage Canal is a manmade or channelized hydrographic feature. Drainage Canals are differentiated from streams in that drainage canals have had the sides and/or bottom stabilized to prevent erosion for the predominant length of the feature. Streams may have had some stabilization done, but are primarily in a natural state. Lakes are large standing bodies of water greater than five acres in size. Ponds are large standing bodies of water greater than one acre in size and less than five acres in size. Reservoirs are manmade embankments of water. Included in this definition are both covered and uncovered water tanks. Reservoirs that are greater than one acre in size are digitized. Hidden Streams, Hidden Rivers and Hidden Drainage Canal or Culverts are those areas of drainage where the water flows through a manmade facility such as a culvert. Hydrology Annotation is not being updated but will be preserved. If a drainage feature has been removed, as apparent on the aerial photography, the associated drainage name annotation will be removed. A Mooring Cell is a structure to which tows can tie off while awaiting lockage. They are normally constructed of concrete and steel and are anchored to the river bottom by means of gravity or sheet piling. Mooring Cells do not currently exist in the Allegheny County dataset but will be added. Locks are devices that are used to control flow or access to a hydrologic feature. The edges of the Lock are captured. Dams are devices that are used to hold or delay the natural flow of water. The edges of the Dam are shown.

Response areas for Fire Departments.

The China Administrative Regions GIS Data: 1:1M, County Level, 1 July 1990 consists of geographic boundary data for the administrative regions of China as of 1 July 1990. The data includes the geographical location, area, administrative division code, and county and island name. The data are at a scale of one to one million (1:1M) at the national, provincial, and county level. This data set is produced in collaboration with the Center for International Earth Science Information Network (CIESIN), Chinese Academy of Surveying and Mapping (CASM), and the University of Washington as part of the China in Time and Space (CITAS) project.

Allegheny County land use as ascribed to areas of land. The Land Use Feature Dataset contains photogrammetrically compiled information concerning vegetation and limited open areas of ground. The Land Use Feature Dataset contains Woodlands, Nurseries and Orchards, Cultivated Fields and Athletic Fields. Woodlands are groups of trees, whether coniferous or deciduous. Woodland areas that are one (1) acre or greater in size are digitized from the aerial photography. Nurseries and Orchards are areas that indicate cultivated trees. These areas are usually identified because the trees are found in evenly spaced rows. Nursery and Orchard areas that are one (1) acre or greater in size are digitized from the aerial photography. Cultivated Fields are those areas that are used for crops. Pasture land and land that, according to the aerial photographs and aerial interpretation, has been permitted to lie fallow for an extended period is not considered cultivated areas. Cultivated Field areas that are one (1) acre or greater in size are digitized from the aerial photography. Athletic Fields are sport fields that have a natural surface. The apparent outline of the land area used for athletic purposes is digitized from the aerial photography and not just the actual athletic field.
