13:00-16:00 Workshop 22D: Google Earth Engine for large-scale DEM analysis



  • Using GDAL and PKTOOLS for Raster Operations | Lecturer: Giuseppe Amatulli, Yale
  • GDAL and PKTOOLS are powerful command line utilities mainly used for raster manipulation and analysis. In this workshop we will explain the main principle and philosophy about these tools by showing simple geodata processing for raster cropping and reprojection, image masking, spatial and temporal/spectral filtering as well as image classification. We will explain how to maximize computational implementation and process raster data more efficiently by building up routines that allow saving temporary raster outputs in RAM and use VRT files for tiling operations in a multicore environment. We expect basic command line knowledge (any language is fine) and a general familiarity with geospatial data processing. Participants should bring laptops with the latest OSGeo-Live virtual machine with PKTOOLS already installed.

  • Processing Large Rasters using Tiling and Parallelization: An R + SAGA GIS + GRASS GIS Tutorial | Lecturer: Tomislav Hengl, Envirometrix Ltd
  • This workshop will provide a gentle tutorial on how to implement complex computing using large DEM rasters including LiDAR point clouds, even using a laptop PC. Some of the topics that will be addressed include: converting polygon maps to rasters, downscaling or upscaling (aggregating) rasters to match the target resolution, filtering out missing pixels / reducing noise and multi-colinearity problems, and overlaying and subsetting raster stacks and points, derivation of complex DEM derivatives using tiling with overlap, automated classification of landforms using Machine Learning. For all analysis we will use the power of R and its packages for large data (data.table) and implicit and explicit parallelization (snowfall), newest releases of SAGA GIS (>2.3), GRASS GIS (>7.4) and gdal. The lecturer is an experienced R developer and has more than 10 years of experience with processing global (100 m resolution) DEMs for purpose of soil and vegetation mapping. The lecturer will provide all data and code via github and a local copy on USB stick. Using Linux 64bit OS is recommended but not a requirement.

  • A Hands-On Introduction to RiverTools 4.0 | Lecturer: Scott D. Peckham, CEO and Founder, RIVIX, LLC
  • The purpose of this workshop is to provide a hands-on introduction to RiverTools 4.0. This version includes 64-bit support for the latest versions of Windows, Mac OS X and Linux, a new graphics system, a streamlined graphical user interface and many other new capabilities. Attendees of this workshop will become familiar with the key features of RiverTools 4.0 by working through a set of tutorials. Workshop attendees will need to bring a laptop computer if they want to run the hands-on tutorials. If possible, the demo version of RiverTools 4.0 should be obtained from and installed on the laptop before the workshop. RiverTools 4.0 runs on Windows (XP, Vista, 7, 8, 10), Mac (OS X 10.5 +) and Linux (Ubuntu, Red Hat). The demo version includes all of the DEM data sets necessary to run the tutorials.

  • Google Earth Engine for large-scale DEM analysis | Lecturer: Ovidiu Csillik, Department of Geoinformatics – Z_GIS, University of Salzburg
  • Attempts towards a global geomorphometric atlas have been done in the past when computational power was less evolved than nowadays. In this study, we present a possible way to create a global geomorphometric atlas by taking advantage of the Google Earth Engine (GEE) computational capabilities. To exemplify how accessible, efficient and fast GEE works in geomorphometric analysis we globally derive popular land-surface variables (e.g. slope, aspect, multiple curvatures, and surface roughness) and perform a hierarchical pixel-based classification of topography on three levels of details. The scale of analysis can easily be adjusted to meet the user needs. Performing large-scale morphometric analysis with GEE has the potential to become an important milestone in Geomorphometry.

Registration costs for the workshops are: $125 (regular), $45 (students / ODA countries).
