AGDATA Australia Develops Native Vegetation Classification Software for Landowners using TatukGIS SDK

May 28, 2013 -- A state-wide landcover and tree study was undertaken by the Queensland Department of Natural Resources to identify and classify all vegetation zones across the state. The primary methodology was remote sensing backed up by field surveys. The result was the creation of a vegetation database the government uses to stipulate vegetation management guidelines by which all landholders must abide. The premise of this effort was to assist landholders, scientists, industry, and government with world’s best practice landscape management. Laws were drafted governing management practices in each of the classified zones, with significant penalties for breaches of these guidelines.

While GIS experts had ready access to the spatial data, individual landholders without GIS expertise were being provided a PDF map of their property. The PDF map provided insufficient accuracy to enable landholders to make decisions about use of their land without risk of
accidental violations exposing the landowner to the possibility of prosecution.

AGDATA Australia has used the TatukGIS Developer Kernel SDK to develop a custom mapping utility to enable landholders to load the spatial vegetation data, overlay it on their property, and view the classification of each vegetation zone. This allows landholders to clearly identify the
vegetation zones in relation to their property with sufficient accuracy to safeguard against infractions and risk of prosecution.

TatukGIS support for the ESRI ArcView Shape format and coordinate systems (including PRJ file) was vital for this project. The Developer Kernel (DK) visual layer property control contains functionality to associate the rendering of map features based on attribute field values, making
the process of applying different colours to the vegetation zones trivial. These and other features of the DK component contributed significantly to shortening the project development cycle.

To further aid landholders identify classified zones when in the field, a GPS interface was developed to enable uploading data from the map to handheld GPS units.

The key purpose of the AGDATA development using the TatukGIS DK component has been to provide a simple-to-use GIS tool to landholders who have no formal knowledge or training of GIS. Besides compliance with land use guidelines, this effort is enabling landholders, for the first time, to engage with government authorities over landscape management decisions.
