Abstract: |
Inland lake bathymetry for Lakes Karapiro and Arapuni, including scanned original images published by the New Zealand Oceanographic Institute (1986) and line-work captured from these images.
Also digitized bathymetry from other New Zealand Oceanographic Institute maps. (LAKES_BATHYMETRY)
Also DOC bathymetry from Lakes Areare, Rotomanuka and Ruatuna. |
Statement: |
Raster images from scanned hard-copy maps published by the New Zealand Oceanographic Institute (1986). Vector line-work digitised by Waikato Regional Council. Attributes taken as published on maps 1986. Images for Lake Karapiro and Lake Arapuni in the Waikato Region were loaded into WRC's corporate Oracle Spatial database as at 4th May 2006, and are accessible from corporate Geomedia GIS. The data loaded is complete for lakes Karapiro and Arapuni.
Each image has been printed to A3 PDF and stored: Karapiro - WRC Document # 1072225, Arapuni - WRC Document# 1072224. The raster imagery stored by WRC in R:\users\raster_images\Lakes_Bathymetry |

Lake Arapuni bathymetry image. Layer file - S:\Corporate_Data\TEMPLATES\ARCGIS\LAYER_FILES\GIS_IMAGES\Lakes Bathymetry - Arapuni.lyrx |
Statement: |
Source images can be found in the Waikato Regional Council library (classification 912).
The original images for Karapiro and Arapuni lakes were scanned by Document Management Company in April 2006. The images were then ‘chopped’ into the sections required for load into the GIS. These sections were saved as greyscale TIF images, and processed by ISRU Many/Raw File Converter to apply overviews and tiling (JPEG compressed, Full Tiling, Overviews (Gaussian Method)).
Registration of the images was undertaken using Geomedia Professional.
Attributes taken as published on maps 1986. |
Other Information: |
Images are scanned from the original publications made in 1986. Bathymetry data represented on the maps was captured during the following periods:
• Karapiro: May 1974, March- June 1983 and January 1984
• Arapuni: February, April – June and August 1982
Images have been scanned from original hard-copy maps published by the New Zealand Oceanographic Institute in 1986. These paper maps are likely to have experienced some shrinkage or stretch since the time of publication. The included NZMG map grid on the maps were used to place them in the GIS, however it must be expected that some distortion may exist due to the age of the maps and the scanning process. Whilst the original map has no stated level of accuracy a safe measure of accuracy would be +/- 25m.
The original images were published by the New Zealand Oceanographic Institute (1986). Vector features have been captured by Waikato Regional Council staff.
As at 4th May 2006 images for Lake Karapiro and Lake Arapuni in the Waikato Region have been loaded. Data loaded complete for lakes Karapiro and Arapuni.
NZ Map Grid Co-ordinates:
Stored in NZMG to match graticle marks on scanned images.

Attributes taken as published on the New Zealand Oceanographic Institute maps 1986. |
Other Information: |
Positional Accuracy:
Images have been scanned from original hard-copy maps published by the New Zealand Oceanographic Institute in 1986. These paper maps are likely to have experienced some shrinkage or stretch since the time of publication. The included NZMG map grid on the maps were used to place them in the GIS, however it must be expected that some distortion may exist due to the age of the maps and the scanning process. Whilst the original map has no stated level of accuracy a safe measure of accuracy would be +/- 25m.
Period and Frequency of Record: Images are scanned from the original publications made in 1986. Bathymetry data represented on the maps was captured during the following periods:
•Karapiro: May 1974, March- June 1983 and January 1984
•Arapuni: February, April – June and August 1982.
Data Acquisition Method(s): Source images can be found in the Waikato Regional Council library (classification 912).
The original images for Karapiro and Arapuni lakes were scanned by Document Management Company in April 2006. The images were then ‘chopped’ into the sections required for load into the GIS. These sections were saved as greyscale TIF images, and processed by ISRU Many/Raw File Converter to apply overviews and tiling (JPEG compressed, Full Tiling, Overviews (Gaussian Method)).
Registration of the images was undertaken using Geomedia Professional.
