Distribution Information 7. Metadata Reference Information 1 IDENTIFICATION INFORMATION 1.1 Citation Originator Natural Resource Conservation Service Publication date 1991 Title Soils 1.2 Description Abstract Natural Resource Conservation Service (NRCS) soils mapping. The soils layer can be used to show non-irrigated capability class (suitability for non-irrigated agriculture). The Class number indicates progressively greater limitations and narrower choices for use. The layer can be joined to NRCS database tables to map any number of variables. Purpose Supplemental information ArcView legends: class.avl - draws each soil class in a different color. 1.3 Time period of content 1991 1.4 Status Progress Complete Maintenance/update frequency None planned 1.5 Spatial domain Description Clackamas, Multnomah, and Washington counties in Oregon except area within Mt. Hood National Forest West bounding coordinate -123.47121656 East bounding coordinate -121.65053671 North bounding coordinate 45.82618832 South bounding coordinate 44.85462409 1.6 Keywords Theme keyword thesaurus None Theme keyword Soil Place keyword thesaurus None Place keyword Portland, Multnomah County, Washington County, Clackamas County, Oregon 1.7 Access Constraints None 1.8 Use Constraints None 1.10 Browse graphic Browse graphic file name soil.gif Browse graphic file description Soil capability classes shown with rivers.
