The authors designed a map-to-sequence representation that encodes variable-sized collections of coordinates, polylines and polygons as a formal language.
Autoregressive model generates road and building vectors in one pipeline
MARS represents geometric map features as sequences, allowing one transformer model to extract vectorized roads and buildings directly from overhead imagery.

Zhang and colleagues recast map extraction as sequence generation rather than pixel segmentation followed by geometric post-processing.
Why this paper
From Microsoft
In one line
Treating vectorized map elements as a formal language lets one auto-regressive model generate roads and buildings end to end, with no post-processing.
