Representation | ArcGIS

3 / 5 A short diary of five introductory software sessions, covering Rhino (two parts), ArcGIS, 3D Scanning and Adobe After Effects. Delivered via The University of Greenwich as part of the Landscape Representation module within the Master of Landscape Architecture program.

The Task

3 hour demonstration workshop, first spent introducing GIS (Geographical Information System) as a system and the background of ArcGIS, a software company owned by ESRI. Explored the 3D application of ArcGIS ArcScene and 2D application of ArcGIS ArcMap. Finally, we retrospectively learnt how to connect the content of folders downloaded from Digimap via ArcGIS ArcCatalogue.

Key Notes

ArcCatalogue

  • Download data from Digimap
  • ArcCatalogue > Right click > Folder Connections > Connect to Folder > connect to your Digimap data
  • Open ArcMap > click Catalogue (right-hand side) > drag and drop layers you want
  • Manipulating in ArcCatalogue will allow you to see MORE layers e.g. boreholes
  • Do the same in ArcScene, but note: in 3D there is no scale.

ArcCatalogue

ArcScene (3D)

  • Right click > scene layers > scene properties > vertical exaggeration e.g. 10
  • Customise > toolbars > animation > Camera > capture view (will combine to a smooth video)

ArcScene PropertiesArcScene Animate

ArcMap (2D)

  • Right click > Mastermap TopographicArea > Open Attribute Table (will give all the visual info in data table, and allow calculation of specific areas e.g. road versus buildings – can be treated like Excel)
  • Selection > Select by Attributes OR Select by Location > Select Layer > Add equations > Get Unique Values (will show number of features selected in the bottom left corner) > Right Click > Mastermap > Selection > Create Layer from Selected Features
  • Customise > Toolbars > Effects > Swipe (compare layers underneath)

Printing and Page SetUp

  • Bottom left – layout view versus data view (= equivalent of paper space vs model space)
  • Layers > Right Click > Properties > Coordinates > check it’s British National Grid, to align any imported data layers
  • Insert > New Data Frame > then drag the layers you want to use into this new layer
  • Insert > Scale Bar OR Legend OR North Arrow
