| Abstract: |
Historic shorelines for the Waikato Region. |
|---|
| Statement: |
Shorelines derived from historic aerial photography dating from 1940s to present. This data can be used in conjunction with the separate feature SCIENCE.sdeadmin.COASTAL_SHORELINE_2017, a feature of dataset Coastal Shoreline and Intertidal Area - GIS Layer. The purpose is to indicate shoreline change over time.
East coast shorelines have only been digitised from historical aerial photography where its location is measurably different from the complete 2017 shoreline, and where the shoreline change is beyond the likely error of the photograph. Significant stretches of coast backed by hard rock cliffs, and estuaries away from the main populated areas, where shoreline change is not significant has therefore not been re-mapped for this dataset.
Priority has been given to areas where shorelines are highly changeable, and/or development is at risk from coastal erosion. For the west coast of the Waikato region, from Port Waikato to Awakino/Mokau. The dataset includes a complete west coast shoreline digitised from 2012 WRAPS orthophotography, and the 2017 shoreline has also been digitized from WRAPS 2017 data to provide the best representation of the current shoreline. Shorelines have only been digitised from historical aerial photography where its location is measurably different from the complete 2012 shoreline, and where the shoreline change is beyond the likely error of the photograph. Significant stretches of coast backed by hard rock cliffs, and estuaries away from the main populated areas, where shoreline change is not significant has therefore not been re-mapped for this dataset. Priority has been given to areas where shorelines are highly changeable, and/or development is at risk from coastal erosion. |
|---|
| Other Information: |
Lines showing the shoreline position (toe of dune) digitised from historical orthorectified aerial photographs. Attributes are YEAR of the orthophoto, SURVEY number, RUN description of surveyed areas, and COASTAL_SECTION to provide selections to the coast section/region of interest. Digitising was undertaken at a scale of 1:5,000, and represents as closely as possible the location of the toe of dune/bank/cliff. The accuracy of the shoreline data is influenced by orthorectification (and geo-referencing) errors of the underlying photography, and is dependent on the quality of the photos and control features in each frame. Metadata about the historic orthorectified images used can be found here http://data.waikatoregion.govt.nz:8080/ords/f?p=140:12:15071183388804::NO::P12_METADATA_ID:8029.

Lines and areas showing Historic Shoreline Erosion containing attributes stating year of survey, survey plan and erosion type (blowout, storm scarp, mound or seep) |
|---|
| Statement: |
Used for assessment of coastal hazards and development of coastal development setbacks and coastal hazard policy |
|---|
| Other Information: |
Based on underlying survey work the Historic Shorelines should be ± 1m, but may vary when plan registration points were scarce.
This data can be used for Locating historic foreshore and shorelines, assessment of coastal hazards and development of coastal development setbacks and coastal hazard policy.
The hard copy plans were scanned and registered using underlying CRS parcel data. The ability to register accurately was limited by the amount of parcel data on the maps. Registration was ‘best fit’, lines were then digitised and attributes populated. Some of the plans were compilations of survey records specifically drawn for WRC to show several years of historic shorelines. Data was captured directly from plans where the information existed. Most data is therefore available for the sandy beaches of the Coromandel Peninsula, and river/estuary mouths on the West Coast.
Data quality is based on the hard copy plans accuracy is assumed to be reasonable accurate. As all plans are of survey quality it can be assumed that the foreshore definitions are to the same standard. Some of the plans weren’t very clear in areas where several historic shorelines crossed each other particularly because of them being in black and white. If absolute accuracy is required it must be obtained from the underlying survey plan. Attribute accuracy is also based on the hard copy plans so therefore assumed to be reasonably accurate.
