Resolved Issues¶
GDA2020 Data Issue¶
A bug was found in the update process for the GDA2020 version of Surface Cover and Trees. This has led to rasters not being updated consistently between the GDA94 and GDA2020 versions. This issue has been resolved and for this release all affected GDA2020 rasters have been updated and will now align with their GDA94 counterpart.
Known Issues¶
The progress and status of known, ongoing issues are summarised below. For specific and further details on each issue, please refer to the Release Report identified in the ‘Release identified’ column.

Building - Tree heights near buildings and other trees |
Terrain elevation values used in the calculation of tree heights have been found in some cases to be affected by the surrounding tall features such as buildings and other trees. |
No update at this time. |

Trees over-capture |
On Buildings, it has been observed that there are some situations where significant portions of some roofs have been captured as tree features. This is different from actual tree overhang and may be due some combination of building proximity to actual tree features, dark roof colour and/or shadow across roofs. In Dense, Shadowed and Water Areas, the spectral signature of these areas can incorrectly result in features being extracted as trees during remote sensing. Height calculation can help to exclude the majority of these during production, but where heights are determined to be greater than 2 metres they may persist. |
We are working with our partner to limit these occurrences, as well as improving our processes to identify and correct the situations where they are present. |
Open |
Jun-22 |
Trees restricted to Surface Cover extents |
Trees and Surface Cover have been designed to physically align the cells. Since the introduction of new capture methods new capture areas that extend past the raster index are clipped. |
This will be investigated and resolved in a future release. |
