  ORMAP  
The ORMAP Vision

ORS 306.132(2) "Moneys in the Oregon Land Information System Fund are continuously appropriated to the Department of Revenue for the purpose of funding a base map system to be used in administering the ad valorem property tax system." [1999 c.701 ยง7]

The vision of ORMAP is to develop a statewide cadastral base map that is:

  • Digital,
  • Publicly accessible,
  • Continually maintained,
  • Supports the Oregon property tax system (A&T),
  • Supports a multi-purpose land information system,
  • Strives to comply with appropriate state and national standards, and
  • Will continue to be improved over time.

ORMAP Goals (Project Phases)

GOAL 1

ORMAP Goal 1 establishes that by April of 2002, Oregon will have a statewide easily accessible digital base map system that provides picture images of assessor maps and a limited amount of information.

  • Primary Focus: Statewide system - citizen benefit (eliminate need to travel to courthouse for map)
  • Picture only (no GIS capability)
  • Good cartographic property descriptions
  • Access: statewide on Internet
  • Technical Design (Minimums)
    • Scanned maps: 400 dpi Group 4 (compressed)
    • Index: 1st by county; then by map number
    • Internet Server: single server at Oregon Department of Revenue (DOR)
    • Image type: tiff
    • Image updates: quarterly

GOAL 2

ORMAP Goal 2 establishes by October of 2004, Oregon will have a statewide digital tax map system that supports a limited number of GIS applications. The assessors use ten percent (10%) of the maps in production.

  • Primary Focus: Develop [converting to] GIS base
  • Use basic tax lot info available
  • Accuracy: existing levels (depends on part of state)
  • Applications: limited to existing accuracy levels
  • Access: multi-levels
  • Technical Design
    • Uses available control: requires inventory of existing control
    • Accuracy: poor to excellent
    • File Formats: GIS shape files Database - DB4
    • Coordinate System: NAD 83 (N/S Zone) International feet
    • Web based
    • Minimum Attributes: Oregon Cadastral Data Exchange Standard
    • System updates: annually (at turn of tax roll)
    • Metadata: Compliant with the Oregon Metadata Standard
  • Maintenance - Dual Systems
    • CAD produced
    • GIS produced
    • Manually produced
  • User applications
  • Updating

GOAL 3

ORMAP Goal 3 establishes that by October of 2006, Oregon will have a statewide digital tax map system that supports the needs of the Assessment & Taxation (A&T) function and may be useful for other public and private GIS applications. Fifty percent (50%) of the county tax maps produced using ORMAP Map Methodology and ORMAP Technical Specifications.

GOAL 4

ORMAP Goal 4 establishes that by October of 2012, Oregon will have a statewide digital tax map system that supports the needs of the Assessment & Taxation (A&T) function and may be useful for other public and private GIS applications. Seventy percent (70%) of the county tax maps produced using ORMAP Map Methodology and ORMAP Technical Specifications.

If surplus funds are available, ORMAP will consider funding projects that facilitate and improve the administration of the ad valorem property tax system. These projects could include, but not limited to the following:

  1. Development or improvement of soils maps
  2. Development or improvement of other taxing layers that assist in property tax assessment (i.e., school districts, fire districts, etc.)
  3. Mapping of building footprints

Ninety percent (90%) of the county tax maps produced using ORMAP Map Methodology and ORMAP Technical Specifications.

ORMAP will consider funding projects that facilitate and improve the administration of the ad valorem property tax system. These projects could include, but not limited to the following:

  1. Development or improvement of soils maps
  2. Development or improvement of other taxing layers that assist in property tax assessment (i.e., school districts, fire districts, etc.)

GOAL 6

ORMAP Goal 6 establishes that by October of 2016, Oregon will have a statewide digital tax map system that supports the needs of the Assessment & Taxation (A&T) function and may be useful for other public and private GIS applications. One hundred percent (100%) of the county tax maps produced using ORMAP Map Methodology and ORMAP Technical Specifications.

ORMAP will fund projects that facilitate and improve the administration of the ad valorem property tax system. These projects could include, but not limited to the following:

  1. Development or improvement of soils maps
  2. Development or improvement of other taxing layers that assist in property tax assessment (i.e., school districts, fire districts, etc.)
  3. Mapping of building footprints
