    Oregon Populated Places

    data.oregon.gov | Last Updated 2013-03-01T18:12:24.000Z

    This point theme shows the location of populated places in the state of Oregon as derived from the 1:24,000 GNIS theme. This dataset was created from the USGS GNIS database. Several SSCGIS staff members have worked on this theme over the years. Procedures_Used: The orppl theme was delineted from the 1990 GNIS theme. To get an idea how this coverage was created download the GNIS metadata. The orppl point theme was generated as the orcov theme. It was built for point topology after the theme was generated. it was than copied to oregnis. Arcedit was used to populate the coverage by selecting ppl from the desig item. The theme was again built for point topology. the theme was imported in 1991 and copied to the gniscov name. External was used 5 times to populate the database. the theme was then exported as gniscov. The gniscov was edited and built for point topology. Reselect was used twice. ArcEdit was used 6 times to edit the theme and than renamed to orppl. The theme was than built for point topology. The theme was than copied twice. One of these copies ws overlayed with house90 using the identity using the point .1 fuzzy tolerance and join options to join the two themes together. The theme was than copied to another directory. In the new directory the theme was edited 7 times and build for point topology. The theme was than renamed orppl and copied two more times. The theme was exported twice and built once between 1993 and 1995. The Projectcopy command was used to copy the projection info from the citylimits theme to the orppl. The theme was than exported twice and imported back in to be projected into the Oregon State transfer standard. The theme was built for point topology and imported back in so that metadata could be created for it.

Referrals in the juvenile justice system are analogous to arrests in the adult system. Each row in this dataset represents a unique referral and includes demographic information about the referred youth. Youth may be referred multiple times; hence, some youth are associated with multiple referrals in this data set. For more information please go to: http://www.oregon.gov/OYA/jjis_data_eval

    data.oregon.gov | Last Updated 2011-09-03T22:45:13.000Z

    Hospitals in Oregon The term "hospital" ... means an institution which- (1) is primarily engaged in providing, by or under the supervision of physicians, to inpatients (A) diagnostic services and therapeutic services for medical diagnosis, treatment, and care of injured, disabled, or sick persons, or (B) rehabilitation services for the rehabilitation of injured, disabled, or sick persons; (...) (5) provides 24-hour nursing service rendered or supervised by a registered professional nurse, and has a licensed practical nurse or registered professional nurse on duty at all times; ... (...) (7) in the case of an institution in any State in which State or applicable local law provides for the licensing of hospitals, (A) is licensed pursuant to such law or (B) is approved, by the agency of such State or locality responsible for licensing hospitals, as meeting the standards established for such licensing; (Excerpt from Title XVIII of the Social Security Act [42 U.S.C. § 1395x(e)], <http://www4.law.cornell.edu/uscode/html/uscode42/usc_sec_42_00001395---x000-.html>) Included in this dataset are General Medical and Surgical Hospitals, Psychiatric and Substance Abuse Hospitals, and Specialty Hospitals (e.g., Children's Hospitals, Cancer Hospitals, Maternity Hospitals, Rehabilitation Hospitals, etc.). TGS has made a concerted effort to include all general medical/surgical hospitals in Oregon. Other types of hospitals are included if they were represented in datasets sent by the state. Therefore, not all of the specialty hospitals in Oregon are represented in this dataset. Hospitals operated by the Veterans Administration (VA) are included, even if the state they are located in does not license VA Hospitals. Nursing homes and Urgent Care facilities are excluded because they are included in a separate dataset. Locations that are administrative offices only are excluded from the dataset. Records with "-DOD" appended to the end of the [NAME] value are located on a military base, as defined by the Defense Installation Spatial Data Infrastructure (DISDI) military installations and military range boundaries. Text fields in this dataset have been set to all upper case to facilitate consistent database engine search results. All diacritics (e.g., the German umlaut or the Spanish tilde) have been replaced with their closest equivalent English character to facilitate use with database systems that may not support diacritics. The currentness of this dataset is indicated by the [CONTDATE] field. Based upon this field, the oldest record dates from 08/23/2006 and the newest record dates from 05/28/2008 For full metadata record, please refer to the Oregon Geospatial Library: http://gis.oregon.gov/DAS/EISPD/GEO/sdlibrary.shtml
