This workshop was held 13 February 2015 in Canberra. It was prompted by the recognition that there were various ongoing research activities related to environmental sensing and monitoring in the ACT, including the National Arboretum Phenomic Sensor Array, the ACT grass curing trial, the Namadgi NP cosmic ray sensor, airborne LiDAR and hyperspectral data collection, terrestrial laser scanning activities, and unmanned aerial vehicle sensing development and trialling. No doubt there are other relevant activities not mentioned here, as well as future activities at different stages of planning. This one day workshop was intended to (1) exchange information on relevant recent, current and near-future R&D activities through brief presentations; (2) find common interests and new opportunities for collaboration; (3) determine priorities in terms of data collection and (web) sharing; and (4) discuss where coordination or expansion would be beneficial and agree how to go about it. You can find the presentations and other material on this legacy page.
