Invasive Snake Activity Before and After Automated Aerial Baiting

Aerial Prefeeding Followed by Ground Based Toxic Baiting for More Efficient and Acceptable Poisoning of Invasive Small Mammalian Pests

Introduced brushtail possums (Trichosurus vulpecula) and rat species (Rattus spp.) are major vertebrate pests in New Zealand, with impacts on conservation and agriculture being managed largely through poisoning operations. Aerial distribution of baits containing sodium fluoroacetate (1080) has been refined to maximise cost effectiveness and minimise environmental impact, but this method is stro...

Automated Orientation of Aerial Images

Methods for automated orientation of aerial images are presented. They are based on the use of templates, which are derived from existing databases, and area-based matching. The characteristics of available database information and the accuracy requirements for map compilation and orthoimage production are discussed on the example of Denmark. Details on the developed methods for interior and ex...

Automated georeferencing of aerial images

A method for automated georeferencing of aerial images by means of existing orthoimages and height models is presented. Results with test material of the OEEPE are discussed. The automated process is supported by the use of various thresholds in order to eliminate blunders. Experiences with the settings of these thresholds are discussed. After automatic elimination of some blunders in the autom...
