Addressing is the specific identification of a fixed location (for example, a plot of land, building, part of a building, way of access or other construction) which is represented by a structured arrangement of place names. It may be further detailed with the inclusion of other valuable attributes including geocodes.

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.

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).

Foundation spatial data is defined as “the authoritative geographic information that underpins, or can add significant value to, any other information. It supports evidence-based decisions across government, industry and the community”1. Criteria has been developed to determine non-foundation from foundation. To be classified as foundation, the spatial data must contain one or more of the following characteristics to be deemed ‘foundation’: • be geospatial • essential for public safety and wellbeing • critical for a national and state or government function • contribute significantly to economic, social and environmental sustainability. NSW has adopted the ten data themes identified by ANZLIC. These are: 1. Administrative Boundaries 2. Land Parcel and Property 3. Geocoded Addressing 4. Transport 5. Positioning 6. Place Names 7. Elevation and Depth 8. Imagery 9. Water 10. Land Cover.

Airport is a facility, either on land or water, where aircraft can take off or land. It usually consists of hard-surfaced landing strips, a control tower, hangars, and accommodations for passengers and cargo. This data is held and maintained within the NSW Digital Topographic Database (DTDB) and includes key attributes such as airport name.

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.

Special project orthorectified imagery relates to imagery captured for emergency response purpose or to support decision making in exceptional cases. The purposes for this imagery can include; floods, storms, hail, fire, tidal surges and drought amongst others. This imagery may have been flown at a variety of image resolutions and the coverage extents are dependent on the nature of the situation and the specific technical requirements of the response activity. The coverage of special project orthorectified imagery for NSW is available as variable window mosaic images at varying GSD’s.

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).

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.

Transport data is a representation of the land, water and air networks used to move people and goods, and deliver services, from one location to another. It includes network connectivity and characteristics such as type, name and potential restrictions on what can be moved through the network.
