What is GIS?
Most local government policies, plans and operations depend upon accurate, location-based information.
A Geographic Information System (GIS) is a geographically aware database used to hold this information. Basically, a GIS is a computer technology that combines mapping and information. GIS stored data enables the generation of maps and reports, to provide a planned and systematic approach to collecting and managing location-based information, and to enable elected and appointed officials to improve planning and decision making. Through the integration of data and maps, the decision environment is vastly improved for decision makers.
A GIS performs spatial analysis and uses geographic location to relate otherwise disparate datasets. Some of the information layers included in QLDC's GIS are: land parcel and district boundaries, rating information, streets and road names, rivers, lakes and topography, utility services (drainage, water, sewage), rapid and street number locations, zoning and other land use, vegetation, district wide aerial photography, contours, hazards, census areas, and maintenance information for parks and open spaces.
Examples of GIS use or analysis include:
- Show the water and sewer mains that have had faults within the last six months
- Select all landowners who pay for refuse collection within a specific area
- Identify all parcels zoned Low Density which have Protected Trees or Features on them
- Aid in Civil Defence Emergency through coordinate identification of property owners, water supply.
GIS Mapping and Data
Information about GIS (Geographic Information System) and Charges
If the required maps or data are not available via our website, information can be obtained on a user pays basis and is available from the QLDC Customer Services Team in either Queenstown or Wanaka. The GIS department is based in Queenstown and is available if any further information is required. All charges are exclusive of GST.
General map inquiries will be met by the Customer Services Team. Charges are:
- Full Colour A3 map $5.00
- Full Colour A2 map $10.00
Larger format maps will be generated by the GIS Team in Shotover St. Queenstown Charges are:
- Full Colour A1 map $40.00
- Full Colour A0 map $60.00
Customised/bespoke mapping or analysis/data preparation will be provided by the GIS Team. Charges are:
- Non-profit $30.00 per 15 minutes (or part thereof)
- Commercial $37.50 per 15 minutes (or part thereof)
Data (vector and aerial photos) can be extracted and downloaded free of charge from our Webmaps application here (http://maps.qldc.govt.nz/qldcviewer/)
Council holds the original orthorectified aerial photos in urban and rural resolution tiles
- Urban - pixel size 0.125m, 240m x 360m coverage, NZTM projection
- Rural – pixel size 0.75m, 2400m x 3600m coverage, NZTM projection
The above tiles can be supplied in TIFF or JPEG format. The cost is $50 per tile (Urban or Rural)
Council also holds LiDAR (accurate height information) data with a vertical accuracy of +/- 0.25m for most of the urban areas of the district. The minimum cost to extract the data is $100 for 50 Ha. Data can be supplied as .las or ASCII format or processed into contours (0.25m+ interval) and supplied as 3D dxf file.
