What is GIS?
A GIS (Geographic Information System) is used to display, manipulate, and analyse geographic information.
GIS can be used to visualise data from databases, allowing easier interpretation of that data.
How does GIS work?
A GIS combines layers of information about a location to give you a better understanding of that location.
GIS represents features of the real world as geographic layers.
GIS can be used to solve real-world problems including:
- verifying location,
- creating planning models,
- monitoring environmental conditions.
- routing and tracking vehicles,
- and much more!
Tools for map display, query, geometric processing, or analysis are built into GIS software packages which can be tailored for specific needs.
GIS data most commonly exists in one of two formats: vector or raster.
- Vector data consists of discrete features such as points (manholes), lines (roads), or polygons (parcel boundaries).
- Raster data consists of continuous data made up of pixels (Aerial Photography).
How does Napier City Council use GIS?
Napier City Council's Town Planning and Works Assets Departments both utilise GIS to help carry out their corporate functions.
The Planning Department uses GIS to create, manage and analyse planning and regulatory information (Building Consents, Resource Consents, Subdivisions, Hazard Information, Dogs, etc).
The Works Assets Department uses GIS to create, manage and analyse utilities information (Sewer, Stormwater and Water infrastructure). It is a key tool for Utilities Asset Management.
