| Future of Leaflet | Vladimir Agafonkin | 30m |
Leaflet 1.0 is imminent and focuses on internal rewrites not flashy features: fractional zoom enables smooth zoom levels and ballistic panning; vectors are… | ||
| torque.js internals: how to render 3M animated points on a map | Javi Santana | 28m |
Torque.js renders millions by sending a custom temporal tile format from Postgres that aggregates points into Web Mercator pixels and time bins, so a 1M demo… | ||
| Drawing Maps with OpenGL | Lauren Budorick | 21m |
Mapbox moves map rendering from CPU to GPU using mapbox-gl-native (C++) and mapbox-gl-js; OpenGL only draws lines and triangles so lines become six-triangle… | ||
| Real Time GeoJSON APIs | Jason Denizac | 28m |
Describes a working realtime API that streams GeoJSON features over plain HTTP using Server-Sent Events and the browser EventSource DOM API, emitting… | ||
| Lighting Talks | Brett Camper | 33m |
Coop is an ESRI open‑source ETL that pulls any REST API and emits GeoJSON feature services or tiles; it runs as a Node.js server with provider plugins… | ||
| Making Workers Work For You | Matt Priour | 23m |
Practical guide to using browser workers with measured tradeoffs and gotchas: dynamic creation via blob URLs works cross-origin, but transferable objects are… | ||
| PouchDB and SQLDown | Calvin Metcalf | 26m |
Claims that you can run the same local-db code in browser and Node by swapping LevelDB backends, showing SQLDown to use Postgres or WebSQL and PouchDB adapters… | ||
| Creating 3D web maps with Cesium | Patrick Cozzi | 29m |
Shows a production-ready browser 3D globe built on Cesium (WebGL 3D globe) with terrain, imagery layers, GPU shaders for water/night lighting, and a Sandcastle… | ||
| Maps, Data, and Charts - Bound for Great Things! | Laura Ferguson, Vanessa Archambault | 24m |
A web SaaS that extrudes building footprints and imports interiors from Magic Plan uses Postgres/Java backend, Angular frontend, Node for packages, and three… | ||
