Seacoast is a combination of the coast AND offshore islands such as Great Barrier Island, Kawau Island, Kapati Island, D'Urville Island and many others.

Does not include offshore islands such as Chatham, Kermadec or Campbell Islands.

This is a polygon featureclass, maybe you want Seacoast_ln formatted as a polyline featureclass if your software cannot handle such complex polygons.

These tiles are raster images of the Topo vector data from Corax Topo 2006 vector dataset, created using ArcGIS in the NZTM projection. They are not the scanned hardcopy maps published by LINZ. All tiles are georeferenced and clipped exactly. Annotation can span the tile boundaries.

The scale of the data is designed to be printed at 1:50,000 but the lower resolutions we have for screens compared to a page means that they are more readable at 1:25,000 scale.

To reduce clutter the patterned filled symbols have been simplified to single colours, contours have been thinned.

Annotation from the topo set has been used for labelling, however that did not include road names, spot heights and descriptive text. These have been placed automatically, so there are some clashes.

Pixel size is 4.0 metres ground which results in much smaller file sizes (~ 40 MB) than a high resolution version of an A1 sheet that LINZ issue from the new series (140 MB)

The tiles are half NZTopo50 sheets, 24 km x 18 km covering 43,200 Ha. The rate set is equivalent to $3.00 + GST per tile or $6 + GST per sheet for large areas. You may find downloading the NZTopo50 index layer to make calculation of the cost easier.

Although there are newer versions of the LINZ data (now v 15) there are very, very few edits in each version, and they are limited to a few tiles, so for most of the country this is still identical to the latest version.

Resolution 4.000m

Trig points with 2 metre or 4 metre high beacons on the top of prominent features. They have a survey mark code and common topo name and the height is the orthographic height compatible with the topo elevations, not the datum height reported by your GPS.

These points supplement the spot heights in the topographic database. Spot heights are not duplicated at trig points to remove redundancy. Trigs may not be the highest point because they are placed for visibility when surveyors needed them for backsights to orientate their theodolites for survey bearings.

Type: Height of beacon structure. If there is no beacon, the mark is not in this database, but there may be a concrete mark. Beacons are not being replaced, vegetation is not being trimmed so they are harder to see.

Elevation: Orthographic height in metres

Name: Official mark code (unique 4 character code)

Label: Old name or hill name previously on old topographic maps. Not all trigs have a name, and many are a single letter or a number easily confused with the elevation. Hills may be named separately from the trig common name. Many hills are not named, hence the trig name is used for describing features when mapreading.

SDist: Survey district to resolve duplicate names. This was part of the label, but it is too much information for a map label.

There is a lot more in the LINZ database, available for download at
