Experimenting

Tools and methods for processing

Machine learning algorthms used for feature extraction and classification with stochastic quality measures for certainty. Possible use of spatial and time series models. Java-based implementation. Geo-coded and land use coded feature set data used as input to statistical estimation process.

Privacy and confidentiality issues

Strict adherence to ABS legislation and Australian Privacy Legislation.
