NSW Basemap Topographic

The NSW Basemap Topographic theme provides a seamless state-wide map of roads, features of interest, localities, landform, hydrology, land cover, property boundaries, cultural data, contours and more. It is designed so that it can be used as a standalone reference or combined with other layers of information without reducing the content of the topographic layer.

The web map is regularly updated and will show new information captured or sourced by DCS Spatial Services. All datasets used in this service are authoritative foundational spatial data. Access the NSW Foundation Spatial Data Framework for details and specifications.

NSW Basemaps are vector tile, web accessible maps that enable faster loading times for users and high-resolution display at all zoom levels. Vector tile layers can adapt to the resolution of a particular display device and can be restyled for multiple uses.

This web map service allows users to easily integrate the NSW Basemap into spatial platforms and applications and provides a combined view of NSW Foundation Spatial data.

Relationship to themes and datasets	The NSW Basemap is made up from elements from NSW Administrative Boundaries, Land Parcel Property, Water, Transport and Geocoded Address Themes as well as Features of Interest and Physiography Categories of the Foundation Spatial Data Framework (FSDF) Boundaries
Accuracy	The dataset maintains a positional relationship to, and alignment with, a range of themes from the NSW FSDF including, transport, imagery, positioning, water and land cover. This dataset was captured by digitising the best available cadastral mapping at a variety of scales and accuracies, ranging from 1:500 to 1:250 000 according to the National Mapping Council of Australia, Standards of Map Accuracy (1975). Therefore, the position of the feature instance will be within 0.5mm at map scale for 90% of the well-defined points. That is, 1:500 = 0.25m, 1:2000 = 1m, 1:4000 = 2m, 1:25000 = 12.5m, 1:50000 = 25m and 1:100000 = 50m. A program of positional upgrade (accuracy improvement) is currently underway.
