Objectives: Introduce participants to open source tools R+OSGeo, give some hands-on training and provide enough resources (literature, examples, datasets) so that participants can continue developing his/her skills independently. At the end of the workshop each participant will be familiar with how to load spatio-temporal data in R, reformat and analyze it, visualize it using Open Source GIS and Google Earth and write results in various formats. We also aim we also aim at getting Australian/NZ scientists more involved in the R+OSGeo activities (both as users and contributors).
Target group: Australian/NZ scientists that use Spatial Data Analysis in their work but are not GIS specialists or spatial statisticians; various backgrounds (economists, engineers, scientists, mathematical modellers, etc.).
