Metadata
This page summarises the details of the various information (metadata) currently available for the Motueka Catchment.
Items in italics denotes data from Les Basher, Landcare Research, for which the source is unsure.
NOTE: This table will be added to periodically during 2001. Information/maps will be clickable (currently not available at April 2001).
| Data Type | Comments |
Location and Topography |
|
1:50k Topodata |
contours, roads, rivers etc which Landcare also has access to. Peter Inwood commented that roads coverage is not brilliant in some areas. |
| 25m resolution DEM generated from 1:50k 20m contours | At landcare Research, Lincoln. Derivative products - shade map, aspect and slope data (we can generate a variety of derived surfaces like compound topographic index as required) - contact James Barringer |
| Landscape | areas of high visual quality |
 |
|
Climate and Hydrology |
|
| Catchment boundary from DEM | (also old MOW catchment
boundary coverage)
Sub-catchments can be generated on demand from DEM. |
| Stream network from topographic database and/or generated from DEM. | |
| surface water | flow - mean, median, low, flood (list of historic floods and their flows), etc at subcatchment level; suspended sediment?; drought scenarios? |
| groundwater | location of aquifers & recharge areas, yield?, vulnerability to contamination, drought scenarios? |
| diagrams of water take by source&use, water take by zone; water extraction through time | |
| Rainfall, river gauge and water quality data for sites managed by TDC. | point data |
| Mean annual rainfall isohyet map | hand drawn by Martin Doyle and digitized into GENAMAP and translated to shapefile format. |
| Can also generate rainfall or other climate surfaces from NIWA point data and DEM etc. using ANUSPLIN on demand (e.g., temperatures, ET, sunshine) | |
| Soil moisture deficit data from Barringer water balance model on demand | Can be generated if required |
|
|
River Cross-Sections |
|
| Earliest well-surveyed cross-sections in about 1957 | Only up to Alexander Bluff plus at the gauging stations for flow ratings etc. |
| Computerised cross-section records run from 1992 to the present | stored in SDRMAP + hard copy as half tones with map and cross-section information on them (see example).Cross-sections are run about every 4 years. The half-tone card file recording system that includes these cross-section maps. |
| River control works | |
| Gravel extraction sites | (quarries, pits) |
|
|
Geology |
|
| QMAP - CD from GNS | Held by Peter Inwood - available to TDC partners for specific projects. |
| NZLRI lithology data | Held by Landcare Research and TDC |
| Generalised A4 map from TDC report. | |
| Geological/soils/landscape sites of significance | |
|
|
Soils |
|
| NZLRI soils are available through Landcare - 1:50 000 scale but fairly coarse. | Note that LRI is available in original polygonal data plus FDLs for all 16 attributes including available water capacity and other soil properties. |
| NSD - national soils database | Not likely to be much data (if any) in actual catchment but still to be checked. Held at Landcare Research Massey and Lincoln. |
| Generalised classification from ???? (A4 size) | |
|
|
Vegetation |
|
| Land Cover Data Base (LCDB) | Landcare has access to this. This data is derived from SPOT satellite imagery at around 20 metre spatial resolution. The imagery is classified into some 15 class types. It may lump together some cover types of interest (e.g., crops). |
| NZLRI data | Also available, although now fairly dated (may have more value as a historic view of vegetation in the late 1970s). Land use capability (NZLRI), productive land classification; land use trends through time (and population trends?) |
| National Vegetation Survey (NVS) | Permanent plot site data for native forest areas - uncertain if this database has any valuable Motueka specific data but worth checking. Held at Landcare Research, Lincoln (see Peter Bellingham/Larry Burrows). |
| Native forest cover (1840, 1980, 1996) | |
| Wetlands | from TDC Access database |
| Pest Control(Biosecurity) - | Locations of weeds eg., giant buttercup, gorse, broom, hawthorn, budleagh, old man’s beard + maps of management areas for weeds and pests? |
|
|
Ecological |
|
| Ecological districts | Landcare holds a copy of old DOC ecological regions and districts database (update to come from DoC late 2000) |
| Arthropod collection | Is this data of any value - either for insect pests and or native species. Held by landcare Research, Auckland. |
|
|
Aquatic biology |
|
| 1988/89 survey | macroinvertebrate sampling sites/species richness/density/MCI, native fish distribution, trout numbers by location/through time |
| Stream classification for trout habitat/forest harvesting | (ex-Weyerhauser?) |
|
|
Marine |
|
|
|
Hazards |
|
| Hazards, faults, flooding etc. | |
| Point source pollution from buried drums of chemicals in Motueka Catchment - | Information provided by Jenny Easton at TDC. - maps, photo and report (see copy). |
| GR N27 006012 | |
|
|
Statistical |
|
| SUPERMAP/mesh blocks | StatsNZ data access/costs. TDC only have textual data down to lowest level, their mesh blocks are at the first level of aggregation and not currently linked to the textual data in the GIS. According to Peter Inwood there should not be too much problem in accessing the full SUPERMAP data for the area from StatsNZ if it is required (including previous census results if these have value). |
|
|
Cultural and Legal |
|
| Digital Cadastral Data Base (DCDB) useable by anyone working for or with TDC, no links to valuation etc. | This is the standard legal boundary database maintained by Land Information New Zealand (LINZ) which includes roads and all surveyed property boundaries. It is important to note that it is constantly being updated as new sub-divisions and developments are being carried out so it can become out-of-date locally quite quickly |
State of the Environment Report |
C |
| Environmental monitoring sites/information (possibly same as above) | flow, rainfall, temperature, groundwater, etc; discharge sites, dairy shed locations, water abstraction sites, water quality/biota, cross-sections (with links to plotted elevation changes), soil sampling sites |
TDC Consents database |
Includes 8 figure grid reference (might be useful for land use). |
| Services | water, sewage, storm water drains. |
| Agribase ?? | Talk to Peter Newsome at Landcare Research Massey about availability and content |
| Tasman Resource Management Plan - Planning Maps | Book of A2 size maps at
several scales. Of most interest are 1:50k maps and 1:5k urban
area maps. Map sheet 24 at 1:50k covers Motueka itself, but the
catchment is probably included in maps 23, 24, 26, 27, 28, 29,
30 ,31, 33 and 34.
Based on the legend the following information should be available:
All of this data is available from GENAMAP databases according to Gwen Nicholson the TDC GIS operator. |
| Archaeological/ historic sites of significance, Iwi, pa sites? | |
| Planning maps |
|
|
|
Satellite Imagery and Air Photographs |
|
| SPOT image from MoF dated February/March 1996 | (presumably the data from which the LCDB was generated). |
| Also some recent Landsat data | Contact Stella Belliss, Landcare Research, Lincoln. |
| Air photos | Air photos are not
properly archived (some held in offices) and any records of what
is held are in card boxes at TDC in the file storage area. All
photos are NZ Aerial Mapping styles B/W photos. There are also a
variety of oblique aerial and ground shots in their physical
image library, and they have some video footage of floods (e.g.,
1995). We have been given flight line maps for the 1946 survey,
as well as some flightlines from Aerial Surveys taken 1996-98
that TDC do not hold.
|
| Half tones of rivers every 4-5 years starting mid-1950s (mostly 1:4k up to 1-8k). | Could be extremely useful for riparian characterisation work. |
| From 1964 there are ad hoc plots showing flood extents (I think on half tones), | Doug Nottage has collection of news paper cuttings about historical floods. |
| Also lots of imagery of towns | (very detailed - 1:500 scale) |
| Some old paper cadastral/property surveys from the 30's are also in storage. | |
| All half tones held at TDC are recorded in a card file system. | Best contact for all the photo and map data is Doug Nottage. |
|
|
Data from NIWA |
|
| All point data retrieved from CLIDB - grid reference, site information and attached data for climatic variables. | May need to relook at
getting all of the stations for the upper North Island since the
first cut I made at grabbing stations round the catchment has
very few sites in the west. Probably need to get right over to
include the west coast.
