PART I of IV

(September 16th – 17th 2019)

‘QGIS & Open Source Geo Data Portals’

Finding, Downloading, Linking & Mapping Data; Import/Export Functions for Different Formats and Data Types (Raster, Vector, Table)

Exploring the Digital Terrain of Svalbard via QGIS. Layering of Geo-Data; Accessing with QGIS a local Database or connecting to WMTS and ArcGIS-Map-Server online services. Custom Previewing Options for Raster- and Vector-data; adjustment options of symbology and graphical appearance, such as transparency-, stroke-, colour-, custom-gradient-ramps-, points- and blending mode settings; Grouping and Layer Organisation/Hierarchy in the Layer-Manager; Setting and Changing the CRS (Custom Referencing System); Clipping of Data with precise coordinates; extracting layer extends and custom interval contour lines; saving Vector Data as SHP-Files to local GIS-Database and as DXF-Files to CAD Import location Folder; saving Raster data as ASCII-Files to CAD Import location Folder; exporting SHP-Files and importing them in Illustrator with precise location and scale.

PART II of IV

(October 7th – 11th 2019)

’Terrain Design Information & Speculative Trajectories of Natural Dynamic Processes’

Parametric Data Mapping / GIS to CAD / 2d to 3d / Simple Protocols of Transformation, Rotation and Scale

Creating a ‘Svalbard-TDIM’ (Terrain Design Information Model) for a specific Project/Geo-location & Territorial Extension; Clipping Data and extrapolating Terrain Attributes using SagaGIS and Terrain Analysis Modules; Creating an Attribute Table and storing calculated attributes to XY-coordinates/cells within a raster/grid/database; Exporting Geo-Data in different Formats to a CAD Import Folder Location; Creating of custom ‘3d-terrain-informed-planes’ orienting Geometry in normal direction to the terrain; decomposing a mesh; Accessing Attributes/Information such as: Solar Potential, Wind Exposition Index, Water Accumulation and Flow Direction Index, Topographic Wetness Index, Slope, Aspect, etc.; Calculating, filtering and applying of basic protocols of transformation, rotation and scale; Reconfiguration of the existing Digital Terrain Model through parametric interaction; altering the Terrain-Fabric, -Identity and -Conditions (DTM); Creation of a New Re-configured Database; Calculating and highlighting of differences of change with the Original Data; Understanding Terrainmodification as a tool to redirect dynamic trajectories of natural processes and thus transform Terrain not just in its physical 3 dimensional appereance but in its ability to accomodate different Properties.


PART III of IV

(October 21st – 25th 2019)

Altered Terrain Part II & Rapid Prototyping of small-scale Physical Models/Samples

Parametric Data Mapping; Rapid Prototyping

Calculating, filtering and applying of further protocols of transformation, rotation and scale; reconfiguration of the existing Digital Terrain; Setting Attractors and Calculation of Distances & Influences; Buffering Values; Digital Terrain Manipulation through simple scripting techniques / addressing the local database; processing Data for Digital Fabrication; Creating Test Files for Laser-Print, feeding Information of results back to the digital Model; adjustments specific to material properties


PART IV of IV

(November 4th – 8th 2019)

Digital Fabrication & Optimizing Processes for Laser-Printing’

Preparing Digital Models for Laser-Print; Exploring other forms of Digital Fabrication (e.g.: 3d-print)
