The Institute for Natural Resources (INR) uses, processes, and maintains several types of GIS data, including: data for which INR is the official data steward; project specific databases; and local copies of other regional and local data.

INR maintains Oregon's most comprehensive database of rare, threatened and endangered species through its Oregon Biodiversity Information Center (ORBIC). This database includes site-specific information on the occurrences, biology, and status of over 2,000 species throughout Oregon. It includes the state's only database of natural vegetation, with descriptions and information on the occurrences and protected locations of all known ecosystem types. As part of the Natural Heritage Network overseen by Natureserve, ORBIC is able to share this data internationally.

Project-specific Data and Databases

INR has numerous project-specific databases that include primary data collection (such as from National Park Service projects) and processed data. Data can be processed numerous ways including: 1) modeled and imputed data, 2) standard GIS and image processing techniques, and 3) database processing. Highlights of recent project-project specific data and databases include:

Sage-Grouse Conservation Partnership (SageCon) Data

SageCon Data. Sage-Grouse Conservation Partnership (SageCon) was convened by the Oregon Governor's Office, the Natural Resources Conservation Service (NRCS), and the U.S. Bureau of Land Management (BLM) in 2013 to proactively address USFWS’ 2015 Sage-Grouse listing decision in 2015. By addressing key threats to sagebrush habitat, SageCon has been working collaboratively with ranching and farming communities in central and eastern Oregon, as well as emerging industries such as mining and renewable energy, to ensure species protection for sage-grouse protection. The goal for the collaborative effort was to develop an “all lands, all threats” plan for sage-grouse conservation in Oregon. Data used for the plan are publicly available.

National Park Service Assessment Projects Datasets

NPS North Coast and Cascades Network. INR has completed or is in the process of completing several vegetation mapping, inventory, and classification projects for the National Park Service (NPS). These datasets are published through the NPS North Coast and Cascades Network website upon final acceptance and publication of the reports and associated data.

INR Modeled and Imputed Data

Integrated Landscape Assessment Project (ILAP) Data, Models, and AnalysesAccess ILAP Data, Maps, Models, and Analyses. Vegetation estimated and structure modeling using models such as random forest, canonical correlation and other imputation methods; or species models using similar tools and data. Examples of this include:

  • Potential Natural Vegetation (PNV) of Oregon and Washington

  • Oregon/Washington arid land vegetation composition and structure

  • Vegetation Dynamics and Treatment (VDDT) models

  • ILAP VDDT modeling results and crosswalks from modules

  • VDDT modeling strata2 grids and other strata grids to link to model output

Willamette Water 2100 Project. Simulations of water supply and demand under various climate and population growth scenarios developed with couple human and natural systems model.  Developed as part of a National Science Foundation project focused on water scarcity.


GIS and Image Processing

Data can be processed using standard GIS operations and image processing techniques. There are numerous raster based datasets that are used to evaluate land use and cover. These raster databases typically represent one point in time and are from aerial photography or from Thematic Mapper imagery. These have been used (in conjunction with other data) to map current vegetation in the Portland metropolitan area through image classification, etc. Details of these data are provided in next section.

Database Processing

Numerous GIS database have complex data designs that require database management and modeling to build geographic databases. INR staff utilizes database management systems including Oracle, SQL/Sever and Access to programmatically build specific databases. One example includes soils, which have variable depths and numerous attributes. Specific database programs have been used at INR to build depth dependent data sets. For instance, for input into global climatic models, we developed programs to build databases for the 3 separate soils profiles (top 50 cm, 50 to 200 cm, and below 200 cm) for primary attributes including (see Appendix A for complete list):

  • Available water capacity
  • Percent sand

These programs have been modified to build output that provide depth integrated (one number representing the entire profile) for other soils characteristics such as natural drainage, etc. In addition, there are numerous GIS databases which are temporal in nature and continuously changing. These event based datasets typically maintain a base GIS coverage with linkage to on-line data systems.

Event-based Data

INR uses numerous data sources that identify the specific location in time and numerous attributes associated with the event. Examples of this include many point/sample locations where on-going data collection is occurring. These databases require specialized database programming and mapping techniques. This includes common and updated linkages to online time series data collection activities, specifically including:

  • USGS NWIS Daily Value Data (Discharge; Daily Averaged Real Time Data) — The USGS National Water Information System (NWIS) provides access to millions of sites measuring streamflow, groundwater levels, and water quality.
  • EPA STORET(STOrage and RETrieval) — STORET is a repository for water quality, biological, and physical data and is used by state environmental agencies, EPA and other federal agencies, universities, private citizens, and many others.
