Honolulu Land Information System
The City and County of Honolulu has developed one of the most comprehensive GIS data base for any municipality of its size. The Honolulu Land Information System (HoLIS) is an enterprise-wide system serving over 15 City Departments with land use, permit, tax, infrastructure, and environmental data. Geographically referenced information links existing City records to precise locations on the island of Oahu for spatial query and analysis.
The HoLIS provides a rich, full source of geographically referenced information. The GIS serves the public by collecting, maintaining, and distributing geo-referenced information necessary to support City operations. Now this information is also being made available to the public to promote its use for developing local business and marketing opportunities. HoLIS gives everyone a better source of geographic data.
A Data Rich Source of Information
There are currently over 80 different geographic data layers stored in the HoLIS spatial data base. Additional information continues to be added to an already comprehensive compilation of geographic data. These data allow for the development of an unlimited number of GIS applications and studies.
Geo-referenced information available through the HoLIS includes:
- Subdivision/Cadastral Base Maps
- Tax Assessment Designations & Values
- Land Ownership
- Master Planning Designations
- Regulatory Land Use Designations
- Existing Land Use & Activities
- Socio-Economic & Demographic Data
- Infrastructure & Utilities
- Public Recreational Facilities
- Health and Human Service Facilities
- Topographic contours
- Surface terrain models
- Transportation Corridors/Address Ranges
- Flood and Natural Hazards
- Natural and Environmental Resources
What is a GIS?
A Geographic Information System (GIS) is a computer system which handles geographic information. A GIS is a set of computer and cartographic tools to input, manage, and manipulate geographic and descriptive data.
Geography acts as the framework for mapping features and events, and for studying their patterns and processes. A geographic data base is a collection of spatial data, e.g. parcels, and related descriptive data, e.g. land use, that are shared and used by a variety of users for a variety of purposes.
The solution to many problems often requires access to several types of information that can only be linked by geography. With a GIS you can map traffic accidents, look for patterns in water pipe breaks, model sewer system flows, and analyze demographic data.
Why is GIS Important?
Think about the major issues facing Honolulu and all of Hawaii - crime, housing, traffic, economic development, water resources, and environmental protection - each of these has a critical geographic dimension.
A GIS stores information about the earth's physical features as a collection of thematic layers that can be linked together by geography. This simple but extremely powerful and versatile concept has proven to be invaluable for solving many problems.
Only GIS technology allows you to store and manipulate information using geography; and to analyze patterns, relationships, and trends in that information to help you make better decisions.
