jsfreemaplib

Miscellaneous JavaScript functions and classes for working with (primarily OpenStreetMap) geodata, including functions for working with Spherical Mercator projection, managing XYZ-tiled data and downloading and using Terrarium DEM data. Also one or two UI classes such as a Dialog.

versions 0.4.x

Version 0.4.2 - non breaking change - added DemApplier to apply DEM data to GeoJSON data.

Version 0.4.0 introduced one significant change, in the DEM class, if getHeight() cannot find an elevation in the DEM, it will return Number.NEGATIVE_INFINITY rather than -1, to allow for below-sea-level elevations.

versions 0.3.x

Versions 0.3.x are not fully compatible with the 0.2.x series. In particular there are changes to the Tiler and DEM classes, see the source code for detail. The other classes are unaffected.

A new DemTiler class has been added to handle tiled DEM data in Terrarium format.

Note that aframe-osm-3d version 0.1.x is not compatible with jsfreemaplib 0.3.x. You must continue to use 0.2.x. aframe-osm-3d will be updated to be jsfreemaplib 0.3.x compatible in due course.
