Participants will learn during this workshop how to obtain and to prepare GIS layers for SDMs (MAXENT, boosting, bagging and ensemble models), Marxan, ZONATION and similar applications. While this workshop will primarily deal with front-end modeling applications, and how to streamline and to batch (automatize) them for predictions and repeated runs, it will also deal with (repeated) posterior analysis of already obtained predictions and optimizations. Topics featured during this half-day workshop will be automated online data queries and downloads (GBIF and others, web-feature-services), presence-only data processing and GIS imports, environmental data downloads and raster preparations (e.g. Worldclim, IPCC, ETOPO1, World Ocean Atlas), socio-economic and road data, raster processing (e.g. NAs, clipping, projections, re-sampling, importing across formats, directory management), random point creation and prediction lattices, as well as several methods to do repeated overlays (“drill downs”) with many (!) GIS layers within a geographic projection. Landcover data sources, and the use and basic processing of Remote Sensing imagery will also be presented, as well as how to assemble socio-economic data layers. Techniques on how to carry out scenario runs and simulations will receive specific attention, dealing with processor memory considerations. Posterior modeling methods include computations of ROC, confusion matrices, Kappa and to summarize data from SDM and MARXAN runs for analytical publication purposes. Some basic layout and cartography topics of map predictions and underlying data sharing will be shown. The ultimate aim of this workshop is to enable participants worldwide for SDM and Strategic Conservation Planning models with OpenGIS tools so that they can deliver accurate and repeatable results quickly and to convince in their own subsequent SDM and MARXAN/ZONATION runs.
