Spot Height is a point feature class representing individual points on the earth’s surface, the elevation of which has been related to a datum by ground or photogrammetric survey. It is a part of the NSW Digital Topographic Database (DTDB).

Spatial Service’s standard imagery capture program covers the entire state of NSW. Standard coverage imagery is captured and processed at a 50cm Ground Sample Distance (GSD) and is available as either 5km x 5km image modules or mosaicked to the extent of a 1:100,000 mapsheet.

Imagery is the product created from the use of airborne, space borne or terrestrial sensors. These technologies image the surface of the Earth to allow for the visualisation of land surface features. Imagery includes data sourced from satellite, aircraft and vehicle mounted sensors. These technologies have a range of capabilities that includes but is not limited to, the ability to record multispectral and hyperspectral data and produce products such as orthorectified mosaics and stereo-viewable imagery.

Positioning is NSW’s authoritative, reliable, high-accuracy spatial referencing system. The Positioning theme includes the coordinates and their uncertainty of all location-based data promulgated from, or related to, the Geocentric Datum of Australia (GDA94) and the Australian Height Datum (AHD71).

Elevation and Depth is the measurement of the Earth’s surface above or below a vertical datum to obtain the height of the land. Data is collected using a range of sensors including: laser, sonar, radar and optical. Technical methodologies are used to derive spot heights, raster surfaces, contours, triangulated irregular networks and digital elevation models.

The Cadastral Fabric is made up of the following features within the NSW Digital Cadastral Database (DCDB). Lot: depicts a parcel of land created on a survey plan. Each lot may be represented by standard lots, standard part lots, strata or stratum. Each lot has a lot number, section number, plan lot area, plan number, plan label, ITS title status, and stratum label. Road: represents dedicated public roads which are open ways for the passage of vehicles, persons or animals on land. The road dataset includes public roads in use. Each road type has a section number, plan number, plan label, ITS title status, road type, road width or Crown/Council width, lot number, and stratum label. Unidentified: represents a parcel of land that cannot be identified. Crown land, vested, dedicated and severed land may be included in this category as well as Old System lots for which lot/DP identification cannot be found. This dataset also identifies the locations of 100ft wide reserves, ACT regions, closed roads, crossings, surveyed areas, and un-surveyed areas. Water Feature: represents tidal, non-tidal and ocean waters which form a cadastral boundary.

Australian Bureau of Statistics (ABS) Statistical Geographical Standard Boundaries divides an area of interest throughout the state of NSW on which statistics are collected for purposes under the Census and Statistics Act 1905 (Cth). The ABS Structures are a hierarchy of regions developed for the release of ABS statistical information. The main components are as follows: • Statistical Areas Level 4 • Statistical Areas Level 3 • Statistical Areas Level 2 • Statistical Areas Level 1 • Regional Boundaries.

The State Border is a product dataset created from the LGA dataset which depicts the extent of NSW as described by the gazetted boundaries of Local Government Areas.

Soil Landscapes comprise of the Soil Landscape Series mapping based on standard 1:100,000 and 1:250,000 topographic sheets and Soil and Land Resource Series mapping using catchment boundaries or other areas of state significance. Mapping and accompanying reports provide an inventory of soil and landscape properties of their area and identify major soil and landscape qualities and constraints. The ‘Soil Landscape’ concept integrates soil and topographic features into single units with relatively uniform land management requirements. Soils are described in terms of Australian Soil Classification, Great Soil Group and Northcote classification systems. Key soil materials are also identified for the Soil Landscape Series.

The Administrative Boundaries theme is a collection of legislative, regulatory, political, maritime and general administrative boundaries sourced from local and state boundary datasets.
