Graph Databases: ARC/INFO Back to the Future
Have you ever wished that you could assign attributes to GIS polylines based on their direction? Like, let's say single-line road networks. Attribute values can differ depending on the direction of travel: certain uphill segments of a road network may be impassable in the winter, while those same segments in the downhill direction would present no problem. There are cumbersome workarounds (like two-way linear referencing), but wouldn't it be great to have a GIS database structure that took linear directionality into account? Enter graph databases, a database model that focuses on node-to-node data relationships instead of just their connectivity. Attend this presentation and learn about a geospatial data storage technology that offers orders of magnitude faster processing times over traditional database systems.
