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.

What is GIS and how does it work?

GIS stands for Geographical Information Systems. Nearly all of the geographical information Napier City Council are using now are stored digitally and is used by a GIS to create maps and geographical analyses.

GIS represents features of the real world as geographic layers. For instance Roads and Primary Land Parcels.

A GIS combines layers of information about a location to give you a better understanding of that location.

GIS can also be used to solve real-world problems including:

  • verifying location,
  • creating planning models,
  • monitoring environmental conditions.
  • routing and tracking vehicles,
  • estimate 100 year floods,
  • 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 City Strategy and Infrastructure Departments both utilise GIS to help carry out their corporate functions.

The City Strategy Department uses GIS to create, manage and analyse planning and regulatory information (Building Consents, Resource Consents, Subdivisions, Hazard Information, Dogs, etc).

The Infrastructure Department uses GIS to create, manage and analyse utilities information (Sewer, Stormwater and Water infrastructure). It is a key tool for Utilities Asset Management.

Many of the maps on this website are generated from Council's GIS.
