Mapbox

Fork Versions:

Fork Version Mapbox version Notes
0.0.1 0.42.2
0.0.2 0.42.2
0.0.3 0.42.2 Converting aggregateBy properties from string to number. Otherwise, not able to use exponential/interval stops.
0.0.4 0.42.2 Support for multple aggregate by. Useful for aggregating by count and resizeBy column. Points (along with clusters which already have) will have abbreviated value for all aggregateBys.
0.0.5 0.42.2 Added support for groupBy, for vecotTile(geojson). In each cluster it will have splitups of aggregate based on the groupBy values in the features contributing to the cluster.
0.0.6 0.42.2 Added support for finding features contributing to a cluster, so that we can spiderfy.
0.0.10 0.48.0 Merged version 0.48.0 (latest version while working on this merge). Along with extra features/bug fixes, they implemented support for getChildren/getLeaves in geojson source. We got of our implementation of the same from geojsonSource/geojsonWorkerSource but mimiced mapbox's implementation in vectorTileSource/VectorTileWorkerSource. (We worked on unifinished branches/changes in between, so some version numbers have been skipped.) In this version, the getLeaves method parameters have changed for geojsonSource and vectorTileSource.
0.0.11 0.54.1 Merged version 0.51.1 (latest version while working on this merge). We got rid of custom aggregation/groupBy that we had for clustering and reused clusterProperties introduced in the recent versions. (clusterProperties will work for vector sources geojsonTile is true and cluster is true). Change getClusterLeaves to getLeaves in vector source, to match the function name in the geojson source implemented by mapbox team.
0.0.12 1.10.1 Merged version 1.10.1
0.0.13 1.10.1 Update minimist to v1.2.6

Fork Modifications:

  • Get Pins in Cluster: Expose getLeaves in superCluster via an interface, so that we can get the pins in a cluster and spiderfy them. Same has been added for vectortile source with geojson endpoints and clustering. (It has been implemented by mapbox and has been merged in fork version 0.0.10. But in vector tile source, we have implemented a simillar version of mapbox's getLeaves but for vector tile sources.)
  • Aggregate Cluster By: Allow clusters to aggregated using a field. If a field is specified, each cluster will have a sum value which will be the sum of field values (pin[field]) of all pins in the cluster. Super cluster has built in support for it. But mapbox interface has not exposed it. (It has been implemented by mapbox and has been merged in fork version 0.0.10. We have imported the same clusterProperties but for vector tile sources.)
  • Geojson tiles: Provide geojson endpoints for VectorTileSource. Data fetched for each tile in geojson will be converted to vector tiles and handed back to the original workflow. In addition to the convertion it clusters points if enabled. (When clustering is enabled, it exposes getLeaves for Vector Tile sources simillar to the method in Geojson sources.)

Fork Examples:

  • fork_examples/geojsonTileClusters.html
  • fork_examples/geojsonTilePolygons.html

Known Fork shortcomings:

  • Geojson tiles, always set the cache expiry time to 'undefined' and cache control to 'max-age=90000', ignoring the cache headers in the tile's response.
  • AggregateBy multiple values/group have been implemented only in VectorTileSource(with geojson data urls) but in not GeojsonSource.

Requirements to get rid of fork and use mainstream mapbox:

  • Support for clustering points like supercluster by SOQL. select cluster(location) group by snap_to_grid(location, 0.01) (Very Much required to use mainstream mapbox)
  • SOQL supports mapbox vector pbf format support. (If this can't be done, still the fork's role would be very much minized to just convert geojson response to mapbox vector tiles on client side. Or we can even create a new source/worker without fork like this here: https://github.com/developmentseed/mapbox-gl-topojson).
  • Support for slicing shapes for the given tile. (so to reduce redundant data retrieval. Not required to get rid of fork. Better required for an ideal case.)

Mapbox GL JS is a JavaScript library for interactive, customizable vector maps on the web. It takes map styles that conform to the Mapbox Style Specification, applies them to vector tiles that conform to the Mapbox Vector Tile Specification, and renders them using WebGL.

Mapbox GL JS is part of the cross-platform Mapbox GL ecosystem, which also includes compatible native SDKs for applications on Android, iOS, macOS, Qt, and React Native. Mapbox provides building blocks to add location features like maps, search, and navigation into any experience you create. To get started with GL JS or any of our other building blocks, sign up for a Mapbox account.

In addition to GL JS, this repository contains code, issues, and test fixtures that are common to both GL JS and the native SDKs. For code and issues specific to the native SDKs, see the mapbox/mapbox-gl-native repository.
