NSW Base Map Web\u00a0Service GDA2020


GDA2020 Cached Map Tile service -\u00a0See\u00a0GDA2020\nWeb Services Information Sheet\u00a0and\u00a0GDA2020\nRaster FAQ\u00a0

\u00a0

This Cached Map Tile service is published with a spatial reference\nof WGS 84-aligned-to-GDA2020).\u00a0For users who require a [WGS\n84-aligned-to-GDA94] service the original\u00a0NSW Base Map Web Service\u00a0is still available.

Disclaimer:\u00a0This Cached Map Tile service is created directly from the GDA94\nCached Map Tile service by simply shifting pixels by a distance equivalent to\nthe GDA94 > NTv2-CPD > GDA2020 transformation. This shift must be a whole\nnumber of pixels. As a result, where raster tiles are provided at\nlow-resolution, the display location may differ from true GDA2020 location. For\nexample, a tile at \u2018zoom level 18\u2019, with 60 cm pixel resolution, may appear\noffset from GDA2020 by ~30cm.

\n\n\n\n\n\nThe NSW Base Map web service depicts a map of NSW using layers from the Digital Topographic Database, the Geocoded Urban and Rural Addressing System database and the Digital Cadastral Database.


This includes:
\u2022 roads
\u2022 points of interest
\u2022 localities
\u2022 landform
\u2022 drainage
\u2022 cultural data
\u2022 parks and forests
\u2022 property boundaries
\u2022 street address numbers.

Web service uses/fitness for purpose This web service allows users to easily integrate a NSW base map into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. This web service provides an ideal base map depicting a combined view of NSW Foundation Spatial Information for use within spatial applications and systems.\u00a0

Current State This web service is current and complete. Update frequency As required.\u00a0

Future development This web service is updated when new information has been captured or sourced by DFSI Spatial Services.\u00a0

Standards and specifications OGC compliant and suitable for consumption by common GIS platforms.\u00a0

This dataset is compliant with the NSW Foundation Spatial Data Framework and its specifications.

Relationship to Themes and Datasets\u00a0\u00a0

The NSW Base Map 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)\u00a0 Boundaries

Accuracy\u00a0

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.\u00a0\u00a0
