This dataset provides generalised 10-metre contour information for topographical mapping across Queensland. It has been compiled from multiple source datasets and generalised to an overall 1:50,000 mapping accuracy to ensure statewide coverage. Areas not captured using LiDAR have been supplemented with data from the Shuttle Radar Topographic Mission (SRTM). The dataset has been compiled from various sources, including:
• LiDAR
• Photogrammetry
• Shuttle Radar Topographic Mission (SRTM)
Attributes within the dataset describe the source and accuracy of the data for each feature. The data has undergone post-processing and generalisation to depict the overall flow of the terrain. The primary purpose of this dataset is to offer a cartographic and visual representation of Queensland's elevation features, and it should only be used for this intended purpose.
Important Note:
This dataset is intended for general cartographic and visual purposes only and should be interpreted and utilised correctly. It is not suitable for precision work, spatial modelling, or accurate spatial analysis. Users requiring higher accuracy data for their specific needs will need to source or commission their own detailed survey or LiDAR datasets.

This feature class has been created by merging 10 metre contours from numerous other feature classes to create a whole of state 10 metre contour coverage. Sources include data captured using: - LiDAR
- Photogrammetry
- Shuttle Radar Topographic Mission (SRTM)
Attributes within the data describe the source data for each feature and the accuracy of that source data.
Feature Types: AUXILIARY CONTOUR – An imaginary line on the ground joining points on the ground with an elevation of 5 metres
INDEX BATHOMETRIC CONTOUR – An imaginary line representing every fifth intermediate bathometric contour.
INDEX CONTOUR – An imaginary line representing every fifth intermediate contour.
INDEX DEPRESSION CONTOUR – An imaginary line representing every fifth intermediate depression contour INTERMEDIATE BATHOMETRIC CONTOUR – An imaginary underwater line joining points of equal elevation with a regular 10 metre spacing below the Australian Height Datum. Every fifth Intermediate Bathometric Contour, is classified as an Index Bathometric Contour
INTERMEDIATE CONTOUR – An imaginary line on the ground joining points of equal elevation with a 10 metre regular spacing above the Australian Height Datum. Every fifth Intermediate Contour, is classified as an Index Contour
INTERMEDIATE DEPRESSION CONTOUR – An imaginary line on the ground joining points of equal elevation with a 10 metre regular spacing above the Australian Height Datum, where the portion of a landform dips below its surrounding area. Every fifth Intermediate Depression Contour, is classified as an Index Depression Contour
NOTE:- Only Intermediate Contours and Index Contours are currently classified

ATTRIBUTE_DATE (Attribute Date) - Date of the source map or data where the name of the feature was obtained from. FEATURE_SOURCE (Feature Source) - The source imagery, map, or data that the spatial location and shape of the of the feature was obtained from.
FEATURE_DATE (Feature Date) - Date of the source imagery, map, or data that the spatial location and shape of the feature was obtained from.
ELEVATION_M (Elevation (m)) - The elevation of the feature measured in metres in relation to the Australian Height Datum. This field only relates to Capes, Mountains and Passes otherwise left blank

PFI (PFI) - A Persistent Feature Identifier (PFI) is generated once for each feature at the point of creation. The value of the PFI will stay with the feature through all changes to the feature (both spatial and non-spatial) until the feature is retired.
UFI (UFI) - A Unique Feature Identifier (UFI) is generated once for each new feature at the point of creation (at this point the PFI and UFI will be the same). The value of the UFI will stay with the feature through all changes to the feature (both spatial and non-spatial) unless the feature is split into multiple other parts. If the feature is split, the separate parts will retain the original PFI but new UFI’s will be generated for the split parts.

LAST_EDITED_DATE (Last Edited Date) - Date of the last editing or revision to the feature
UPPER_SCALE (Upper Scale) - The upper scale for which the feature should be considered suitable TEXT_NOTE (Text Note) - For mapping purposes. Additional annotation that can be shown on a map.
ADD_INFORMATION (Additional Informmation) - A comment field (additional information)
Upperscale:

In broad terms, the production process involved generating/deriving 10m contours for each of the source datasets and merging them together into a seamless dataset. Each type of source dataset required different types of processing to generate contours. Common to all sources was a process of generalisation to thin vertices, smooth and remove spikes and achieve a consistency in ‘detail’ or resolution of the contour lines. Finally, contours from the different sources were merged ensuring matching off edges. SRTM derived Contours:
a) A single mosaic was generated from the DSM_H (V1.0) ESRI grid files using ArcMap. b) The Mosaic was re-tiled into overlapping tiles with a 500m overlap using ArcMap.
c) A value of 1.287 was subtracted from the height values of the DEM tiles (to adjust to AHD. (Value obtained from SRTM metadata statement).
d) 10m contours were generated for each of the overlapping tiles using ArcMap (3D extension). e) The contour tiles were clipped back to the original tiles to remove overlap using ArcMap.
f) Contours were smoothed using ArcMap (PAEK Algorithm).
g) Contours were generalised using SAFE FME.
Photogrammetrically derived contours:
10 metre contours derived from 1:50000 photogrammetry for the western portion of Cape York and the Southern gulf were complete and required no further processing.
Contours derived from 1:50000 photogrammetry for the eastern portion of Cape York and North QLD originally had 20m (or greater) intervals. Similarly, portions of the 5 metre contours derived from 1:25000 photogrammetry had 20m (or greater) intervals, or irregular intervals, e.g. 15m, 25m, etc... In both cases, regular 10m contours were regenerated by:
a) Generating a DEM from the existing contours (using pixel size 0.0002°).
b) Re-generate contours using same steps described the SRTM contours. LiDAR Contours:
a) 10 metre LiDAR contours were extracted from existing 0.25m contours by script.
b) Contours were smoothed, then generalised.
Edge matching:
Matching contours from different data sources was undertaken by using ArcMap to generate surface models over the overlap areas. This in effect “blended” the two sources together. Contours were regenerated for the overlap area and a “cookie-cut” replacement made into the base contours. Note that in some areas, contours of different sources differed to a degree that manual intervention was required to merge the two together.
Data Clean:
To eliminate issues where 10m contours coincided with Queensland waterbodies, these were manually investigated and removed where necessary. DNRME’s Reservoirs (with areas above size 0.9 km2) and Lakes (with areas above size 0.45 km2) were loaded in ArcMap and any isolated 10m contours within these waterbodies were deleted. Any waterbody areas less than the above stated sizes were not investigated. A visual check of data in ArcMap was also utilised to complete an audit to remove duplicate contours This dataset is GDA2020 Compliant. The source data, and therefore the captured features, were captured as GDA94 (horizontal only). This data has been projected to GDA2020 by using ArcGIS Pro geoprocessing tool Project geoprocessing. Using geographic transformation parameters ‘GDA94 to GDA2020 NTv2 3 Conformal’.
