dataset |
Abstract: |
The dataset contains polygons of soils of Hamilton City re-mapped from the original Landcare Research layer at 1:5,000. The attributes contain the soil series and the soil classification. |
Statement: |
The dataset contains polygons of soils of Hamilton City mapped at 1:20,000 (by Landcare Research) and updated to a scale of 1:5,000 by Dr Reece Hill of Landsystems Ltd. The attributes contain the soil series and the soil classification. No analytical properties of the soil are included.
The original Soil Survey was carried out in 1962 by J.G. Bruce, Soil Bureau, DSIR. The map was published in 1979. It was digitised in 2002 and the data were stored in ArcGIS. NZSC was determined in 2002. Incidental error correction has been carried out as necessary.
The original data was mapped at 1:20,000 and should not be used at scales greater than this. As soil variability is usually very high, the polygons in this map are not necessarily pure and so may contain inclusions of other known, and variants of unknown soils. |

Other Information: |
This data was created by LandSystems Ltd under contract for WRC.
Updates in this project by Landsystems(Stage 1):
1. Re-digitising of gully soil related soil map unit boundaries (at Soil Group level of the NZSC) using
LiDAR based 2m contours. The digitising was undertaken on-screen by a soil scientist with
understanding and some spatial knowledge of Soil Groups and their distribution in a several of the
gully systems in Hamilton. The original soil survey report by J.G. Bruce, Soil Bureau, DSIR, was used
to provide an initial understanding of the soil distribution in relation to the landscape.
2. The on-screen digitising was undertaken using a base map of up to 1:2500 scale. The approximate
scale of remapping is 1:5000.
3. Some additional Soil Groups were remapped in places. These included Soil Groups MO, NO and LO.
However, this was variable and where the LiDAR based 2m contours indicated an obvious
discrepancy.
4. No complete soil map units were added or removed as this would require field observation to be
certain of the discrepancy.
Updates in this project (Stage 2):
1. New soil map units were added where the original soil survey report by J.G. Bruce, Soil Bureau, DSIR
did not extend to the new Hamilton City boundary.
2. Smap (https://smap.landcareresearch.co.nz/) soil map units (at Soil Sibling level) were used to guide
the digitising of new soil map unit polygons. Reclassification to soil series was based on the correlation
information provided by Soil Sibling factsheets (https://smap.landcareresearch.co.nz/factsheets/).
3. Expert opinion by a soil scientist and based on air photo interpretation and LiDAR based 2m contours
was used to refine the placement of soil map units.
4. The final digitised data underwent a QA process to remove digitising artefacts and the its topology
rebuilt and normalised with a location precision of 0.01m.
5. The GIS data is supplied as an ESRI shapefile expressed in New Zealand Transverse Mercator
Geodetic Datum 2000 projection. |
