A compact, symbolic language designed to encode and procedurally visualize bridge structures within GIS and 3D rendering ecosystems.
Spanskrit was designed as a compact, symbolic language to encode visual bridge structures for use in GIS and 3D rendering ecosystems. It enables geospatial features, such as polylines representing bridges, to be annotated with rich visual semantics that drive real-time or precomputed visualization pipelines - with elements that are "close enough" to make geo-specific features recognizable without the need for hand-modelling.
Spanskrit.org is a volunteer organization, designed to build bridges between industry players and foster collaborative effort on the review, refinement, and expansion of the Spanskrit specification that benefit the wider GIS community.
While GIS systems have well-established attribute models for bridge classification (e.g., type, number of spans), there exists no standard symbolic syntax to visually describe a bridge's *form* or *structure* in a lightweight, procedurally-generable way. Spanskrit fills this gap by providing a linearly parseable DSL that:
Requires no detailed 3D geometry
Is easy to embed in geodatabase attributes
Encodes compositional structure (arches, pylons, trusses, cables, stays, etc.)
Allows plausible bridge modeling in low-latency environments (e.g., CesiumJS, Unity, Celerity, Unreal, etc.)
Provides a starting point for standardizing visual semantics of bridges across GIS datasets
ArcGIS: use the "Make Bridge" tool to a "buddy" feature that is attached to the section of road you want to decorate as a bridge. Add an attribute to that bridge feature called "SPNSKRT" and fill it with the Spanskrit string that describes your bridge
QGIS: for "bridge" vectors, add the "SPNSKRT" attribute to your attribute table. For each bridge that has a descriptor string
Your software: similar to the above
Spanskrit descriptions need not be applied to all bridges in your database; use only when geo-similarity is desired - for instance, flight training databases that include bridges as navigational aids; when a particular "look" is desired, but exact geo-specificity is overkill.
