Interpretative mapping

Interpretative mapping and RS data

In a completely digital domain, we need:

  • Spatial registration of dataset
  • Information stacking
  • Data interactivity (I/O)

GIS offer a useful environment

The craft of a geologic map in a GIS

We need 3 elements:

  1. Data interoperability
  2. Digitizing environment
  3. Graphical rendering (symbology)

Data models

There are 2 models for editing/storing vector data

  1. Eulerian model: node/boundary
  2. Points/line/polygon model


from Frigeri et al., 2004


Contacts to Geologic Unit loop

For point/line/polygon paradigm we need a geoprocessing loop


  • Which are the pro/cons for each model?
  • What are the software/tools available?
  • Is there some tool/project still needed?

discussion is open at the poster session! alessandro.frigeri@inaf.it
