Originator Metro Data Resource Center
Publication date 1988
Title Streets
1.2 Description
Abstract Regional street network with geocodable addresses.  Each street segment has all address components for address matching.  Streets are categorized by type for cartographic purposes.  A separate annotation layer is available. These streets and address range information is used by 911 centers for dispatch information.  Since the accuracy of this information is important for emergency dispatch, they provide updates on a regular basis.  Virtually every street in the region is on this map.
Purpose For locating street addresses and for cartographic products requiring a street base map.

2 DATA QUALITY INFORMATION
2.4 Horizontal positional accuracy

The street linework is contained within the street rights-of-way as shown on the tax lot layer.  As the tax lot horizonal accuracy is improved, streets are adjusted accordingly.  <a href="http://mazama.metro-region.org/metadata/display.cfm?Meta_layer_id=41&db_type=rlislite">Taxlot metadata</a>
2.5 Lineage
Process step
Process description Acquired street linework and annotation from Oregon Department of Transportation.  This was digitized from 7 1/2 minutes USGS quad sheets.
Process date 1988
Process step
Process description Replaced linework with newly digitized line work which "fell within" the street rights-of-way from the tax lot layer.  Attributes were transfered from the U.S. Census Bureau TIGER file.  Street names and address ranges were updated using paper maps collected from the three counties.  Thomas Brothers Mapping was the primary contractor.
Process date 1991
Process step
Process description We deleted types 1600, 1900, 2100, 2200, 3100, 3210, 3220. Streets are no longer shown on the Clark County side of the river. Contact Clark County for detailed street information.
Process date 199804
Process step
Process description This layer was reprojected to the NAD83/91 projection (also known as HPGN) as part of a conversion of all RLIS map layers.
Process date 199807
Process step
Process description Projection information (.prj file), compatible with ArcGIS 8.1, was added to the layer.
Process date 20010715
Process step
Process description Add XML metadata compatible with ArcCatalog 8.1
Process date 20011031
Process step
Process description QC street name, addresse, city and zipcodes using E-911 CAD materials for Clackamas County (complete 20020901) and Washington County (complete 20021031).
Process date 20021031
Process step
Process description Hillsboro streets positional accuracy was improved. Streets were snapped to local planimetric data with a +/- 1' tolerance. The City of Hillsboro now maintains their subarea and supplies the data to Metro on a weekly basis.
