Common Points of Interest for King County

Metadata also available as - [Outline]

Frequently anticipated questions:

What does this data set describe?

Title: Common Points of Interest for King County
Authoritative Points-of-Interest layer for King County. Contains over 45 different domain classes showing locations and names for a range of different features. Some classes of features are extensively documented (such as school sites and hospitals) while other classes represent a selected set of all the features of that type (such as hotels and shopping centers). Each feature is represented by a single point describing the centroid of the feature. Multiple points for a single XY coordinate may exist if more than one domain is represented. In other words, a single feature may represent a hospital, but that same point may be represented by another feature (i.e., record) described as a Public Health Clinic. Signficant reviews/updates across a specific domain are described in the Lineage of COMMON_INTEREST_POINT and any domain-specific datasets; other corrections and adhoc updates are not detailed in the Lineage.

    Date: 20-Jul-2018 (process 18 of 19)
    Add new domain (class) to CommonInterestDomain which decodes integer values entered into the CODE item. New value is 901 and defines the domain of Ballot Drop Box locations. Sixty-seven (67) PSAP locatons were added. In addition a new featureclass - BALLOT_DROPBOX_POINT was created which displays the locations using the actual location values (i.e., offset values) rather than the address-centroid based locations depicted in COMMON_INTEREST_POINT.

    Date: 18-Mar-2021 (process 19 of 19)
    Updates to Park and Rides and Bike Lockers. Spatial adjustments made to the locations of the bike locker points.

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    Attributes for each point include address information which is validated independently against web sites or other data. It is also compared to ADDRESS_POINT for validation.

  2. How accurate are the geographic locations?

    Locations are defined by the XY values defined by the authoritative address database for the county (ADDRESS_POINT), and are not independently validated. For some domain classes an offset values is required and this location is defined by the business need, such as transit related points that are aligned to an intersection rather than the default ADDRESS_POINT locaiton. Other point locations may still be considered centroid locations (i.e, based on ADDRESS_POINT), but may be adjusted if multiple buildings exist, or other reason justifies a slight realignment.

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    Dataset represents multiple classes of locations, almost all exclusively to King County. This layer contains all points (features) maintained as common points of interest. Selected children featureclasses, such as SCHSITE_POINT, FIRESTN_POINT, etc, are a subset of this layer. Thus a point (record) for a given named feature will exist both in COMMON_INTEREST_POINT as well as the child featureclass derived by a selection on a value of one or more domains. All domains are classified as to their Hierarchy. A Hierarchy value of 1 indicates that the class is of high importance and diligent effort is made to ensure all features of that class are represented. A Hierarchy value of 0 indicates that the class is maintained only for selected features, guided by business requirements and consumer interest. 1- Airport 0 - Non-Government Building 0 - Building - City Government 1 - Building - County Government 1 - Building - State Government 1 - Building - Federal Government 1 - Police Station 1 - Fire Station 0 - Community Area 0 - Cemetery 1 - Chamber of Commerce 1 - City Hall 1 - Department of Motor Vehicles 1 - Entertainment and Sport 1 - Fairground 0 - Golf Course 1 - Hospital or Medical Center 1 - Public Health Clinic 0 - Hotel or Motel 1 - Library 0 - Major Employment Center 0 - Military Installation 1 - Museum 1 - Transit Center 1 - Other Transportation Center 1 - Fare Outlet - All type 1 - Fare Outlet - Limited type 1 - Park and Pool 1 - Park and Ride 1 - Bike Lockers 1 - Electrical Outlets 1 - Parks and Recreation 1 - Pier or Terminal 1 - School - Elementary 1 - School - Junior High or Middle 1 - School - High 1 - School - College or University 1 - School - Alternative 1 - School - Other facility 0 - Shopping Center 0 - Winery 1 - Ballot drop-off box 0 - Bike shop 0 - Farmers market 0 - Public Access farm 0 - General reference feature 0 - Food Facilty

  5. How consistent are the relationships among the observations, including topology?

    Each named feature is represented by a single point, closely approximating the centroid of the feature. Multiple points may exist at the same XY location if different named feature, representing more than one domain (class) are colocated.

How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
