Metadata Portal Metadata InformationContent TitleNSW Topographic MapoContent TypeWeb MapDescriptionMap Cache Web Service provides rasterised topographic maps in a seamless mosaic view covering NSW. This service generally contains the current standard Topographic maps from the 1:100,000; 1:50,000 and 1:25,000 series.Where coverage exists at multiple scales, the largest scale map is displayed. The sourced Geotiff file is cropped to the map window only, with no legend, disclaimers, map grid, scale bar or north arrow displayed. The NSW Topographic Map series is derived from Spatial Services’ Digital Topographic Database (DTDB). Information viewed in this web service includes:• Roads• Points of interest• Localities• Contours• Drainage• Cultural data• Parks and forests• Property boundaries. This web service allows users to easily integrate the topographic map cache coverage for NSW into Open Geospatial Consortium (OGC) compliant spatial platforms and applications. The NSW Topographic Map Cache web service can be used for mapping, emergency services, natural resource management, geosciences and sustainable development. This service ensures users are able to consume topographic map data without the requirement of hosting the map files on their own servers. It is important to note that depictions of roads and tracks do not necessarily indicate a public right of way. Unlawful entry upon private land or a restricted area and/or wilful damage of property such as gates and fences expose offenders to legal prosecution.

For current information go to spatial.nsw.gov.auData Theme, Classification or Relationship to other DatasetsFeatures of Interest, Water, Transport, Physiography, Land and Parcel, Administrative Boundaries, Land Cover, Place Names and Elevation and Depth themes of the Foundation Spatial Data Framework (FSDF)AccuracyThe dataset maintains a positional relationship to, and alignment with, the state's topographic features including natural, physical and cultural. It is divided into the seven themes of the FSDF and two categories Each of these themes is made up of various Feature Classes (or layers) that contain the relevant spatial data and their associated attributes and relationships. This dataset was captured by utilising the best available source 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 to upgrade the spatial location and accuracy of data is ongoing.Spatial Reference System (dataset)GDA94Spatial Reference System (web service)EPSG:3857WGS84 Equivalent ToGDA94Spatial ExtentFull StateContent LineageFor additional information, please contact us via the Spatial Services Customer HubData ClassificationUnclassifiedData Access PolicyOpenData QualityFor additional information, please contact us via the Spatial Services Customer HubTerms and ConditionsCreative CommonsStandard and SpecificationOpen Geospatial Consortium (OGC) implemented and compatible for consumption by common GIS platforms.
