Vegetation patches larger than 1/2 acre. Based on information from reference data sources including 6" resolution aerial photos, Parks and Recreation natural area assessments, and vegetation surveys along the banks of the Willamette and Columbia rivers. Vegetation patches area classified as forest, woodland, shrubland, or herbaceous. The mapping area includes all land within the City of Portland and the unincorporated parts of Multnomah County that are administered by the City of Portland.

--Additional Information: Category: Environmental Purpose: For analyzing vegetation within Portland's riparian and upland areas. Developed as an input to the Bureau of Planning's GIS model for identifying significant natural resources.

The key goals of the vegetation mapping project were 1) refine the location of vegetation "patches" of areas previously mapped by Metro; 2) incorporate vegetation maps generated by other agencies such as Portland Parks and Recreation and the Portland Bureau of Environmental Services and refine and improve that information where necessary; 3) map vegetation patches meeting Portland’s criteria for inclusion in the natural resource inventory a 1/2 acre minimum patch size versus the 1 to 2 acre patch size used by Metro for the regional dataset; 4) map all vegetation within a 1/4 mile of a surface stream, wetland, or regionally significant habitat resources included in Metro’s inventory; 5) classify the vegetation into four NVCS classes: forest, woodland, shrubland, and herbaceous; 6) further classify vegetation as either "natural/semi-natural" or "cultivated"; and 7) update, refine and improve the vegetation data annually as new aerial photos become available. Update Frequency: As needed

Regionally-designated priority routes to assist in response and recovery in the event of an emergency. Metro and RDPO in collaboration with numerous local, regional and state agencies identified regional emergency transportation routes (RETRs) for the five-county Portland-Vancouver metropolitan region, which include Clackamas, Columbia, Multnomah and Washington counties in Oregon and Clark County in Washington. These routes will assist in the response and recovery through connecting critical infrastructure and facilities and providing access to vulnerable and isolated populations. This layer represents the routes after Phase 1 of the Regional Emergency Transportation Route (RETR) Update. The routes are subject to further review, refinement, and prioritization as part of the Phase 2 work. Date of last data update: 2022-05-19 This is official RLIS data.

Regional Bike Facility and Bike There data. The Bike There! data identifies on-street bike facilities and multi-use trails in the Portland Metro region. In addition, the data identifies streets where bicyclists share the road with motorists.

Streets shown on this map were chosen in consultation with cities, counties, citizen groups, recreational and commuter bicyclists, and transportation planners throughout the region. More experienced cyclists may feel some good cycling streets were omitted from the map. Beginning cyclists may find some of the streets more difficult than they would like. In many cases, neighborhood streets with low traffic volumes and speeds offer alternatives to some of the busier streets shown on the map. The color coding should assist bicyclists in finding the kinds of streets they'll enjoy riding. Date of last data update: 2025-04-28 This is official RLIS data.

Crash Map is an interactive mapping tool developed by Metro to help people access and explore historic motor-vehicle related crash data in Clackamas, Multnomah and Washington Counties. The most recent five-years of crash data available is included in the tool.Crash information is collected statewide by the Oregon Department of Motor Vehicles. It is then aggregated and geocoded (mapped) by the Oregon Department of Transportation’s Crash Analysis and Reporting Unit. The 2018 Motor Vehicle Traffic Analysis and Code Manual provides information on how crash information is coded, including unlocatable crashes. Aggregated, geo-coded crash data is typically available to Metro and other agencies two years after the crash occurred. Metro processes the crash data for the greater Portland area and supports this map for public access.

The classification and mapping of urban forest canopy cover was accomplished using Landsat TM digital satellite imagery. Landsat TM data includes spectral reflectance information from the visible, near-infrared, and middle-infrared portions of the spectrum and has a resampled spatial resolution of 25-meters. The wide range spectral information contained in Landsat TM data makes it ideal for classifying vegetation such as forest canopy cover. Moreover, Landsat TM data was used to produce the original 1991-based land cover map for the Portland area. These forest canopy cover classes were selected due to the proven ability of Landsat TM imagery to effectively discriminate this level of forest cover detail. In addition, other vegetation cover mapping projects in and surrounding the Willamette Valley have used these same or similar cover class discriminations. Unsupervised classification techniques were used to discriminate and map forest canopy cover. The goal in any image classification project is to determine when the image is a good predictor of the vegetative characteristic of interest, such as forest canopy cover. ERDAS Imagine digital image processing software was utilized to stratify the Landsat TM imagery into approximately 150 spectral classes based solely on the spectral information in the image data set. Spectral responses in the imagery, aerial photo and digital orthophotography interpretation, and ancillary GIS data were utilized to determine which spectral classes represent forested areas and subsequently to categorize each forested spectral class into the appropriate canopy cover class. For instance, 51 to 75% tree canopy cover in a residential area is categorized into the same class as an area of 51 to 75% forest canopy cover in a natural area.
