This page contains metadata, or data about data, for our spatial data sets. The data sets are organized by theme which are shown in the table of contents frame. For example, if you are interested in a data set that has to do with water, just click on the water link in the table of contents. Then click on the name of the data set of interest to view the data dictionary. Each data dictionary will explain geographic information about the data set, who the data steward is, how the data set was built, and other associated information. It will also describe the database tables that are associated with the data set. Please contact the data steward (if noted) if you have questions about the content of the data. Their phone number is included within the data dictionary. The export files are shapefiles or geodatabases that have been compressed with WinZip. Projection is a local Albers projection defined for the area of Oregon and Washington in Region 6 of the Forest Service, NAD 83, units are in meters.
Located twenty miles east of the city of Portland, Oregon and the northern Willamette River valley, the Mt. Hood National Forest extends south from the strikingly beautiful Columbia River Gorge across more than sixty miles of forested mountains, lakes and streams to Olallie Scenic Area, a high lake basin under the slopes of Mt. Jefferson. These data sets were made using ESRI© ArcGIS.
Ecoregions are identified by analyzing the patterns and composition of biotic and abiotic phenomena that affect or reflect differences in ecosystem quality and integrity. These phenomena include geology, landforms, soils, vegetation, climate, land use, wildlife, and hydrology. The relative importance of each characteristic varies from one ecological region to another regardless of the hierarchical level. A Roman numeral classification scheme has been adopted for different hierarchical levels of ecoregions, ranging from general regions to more detailed. Included in this dataset is additional details about each level, and downloadable maps and GIS data files.
The Geospatial Data Gateway (GDG) provides access to a map library of over 100 high resolution vector and raster layers in the Geospatial Data Warehouse. It is the one stop source for environmental and natural resource data, available anytime, from anywhere. It allows a user to choose an area of interest, browse and select data, customize the format, then download or have it shipped on media. The map layers include data on: Public Land Survey System (PLSS), Census data, demographic statistics, precipitation, temperature, disaster events, conservation easements, elevation, geographic names, geology, government units, hydrography, hydrologic units, land use and land cover, map indexes, ortho imagery, soils, topographic images, and streets and roads.
