Data Sources Used In This Project
Data sources used in the project are described below. The processing steps used to build the IDU coverage are provided here.
| Coverage Name | Type | Source | Derived IDU Attribute(s) | Comments |
| | | | | |
| Oregon ShoreZone - 2014 | Line | Oregon Geospatial Data Library | D_COAST | Contains shoreline type, ecological suscepibility index, shoreline change rates, and shoreline modifications |
| Statewide Flood Hazards - 2015 | Polygon | Oregon Geospatial Data Library (link) | FLD_ZONE | FEMA Flood Zones. Key to codes is available here. |
IDU Field Definitions
IDU Field Descriptions are provided below. Note that all layers are in the NAD_1983_UTM_Zone_10N projection.
| Field Name | Type | Desciption | Notes |
| PopDens | double | Total Population density (#/m2) | Original Source - Blocks_Pl.shp. In that coverage, PopDens field calculates as POP10 / census tract area, then merged with IDUs using ArcGIS Pro's Spatial Join tool with the "Have their center in" match option |
| PopDensHis | double | Hispanic Population Density (#/m2) | Original Source - Block_sPl.shp. In that coverage, PopDensHis field calculates as P10_HISP / census tract area, then merged with IDUs using ArcGIS Pro's Spatial Join tool with the "Have their center in" match option |
