Change of support

Simple features (OGC + R::sf)

- point
- linestring
- polygon
- multilinestring
- multipolygon
- geometry collection

Types

- Categorical (point -> line)
- Qualitative (e.g. polygon changes shape)
- Clusters (point -> polygon)

Test data

- OBIA
- Tweet clusters

Input

- Time seris of sets of multipolygons
-> One rectangular object

Result

- Where is object A (t + dt)?
- What was the change of support A (t) -> A (t + dt)?

Output

-labelled multipolygons
- extra CoS column
- Hierarichal CoS?
- Encoding CoS

Process

-Machine Learning
