[MetaCRS] Fwd: [ol3-dev] proj4js

[Andreas Hocevar]

I would be willing to lead that effort, because I have plans for
proj4js too, to make it play nicely with OpenLayers 3. These plans
include:

* Move the repository to github (either a proj4js organization or a
metacrs organizations if other metacrs projects want to join).

* Create a hosted build tool to create builds that only contain
projections that the user needs, with the ability to fetch projection
defs (including axis order!) from http://spatialreference.org/.

* Use Closure Compiler in Advanced Mode to ensure builds are as small
as possible.

* Make it extensible so developers can add custom transforms, and add
custom transforms e.g. for Swiss projections, where proj4js only uses
a 3 param transform because it does not do grid transforms.

* Make the validity extent a property of the projection, and let the
custom build tool fetch validity extents from
http://epsg-registry.org/ (or http://spatialreference.org/ if we can
agree on a way to extend either proj4 defs or OGC WKT defs to include
the validity extent).

I went ahead and created both proj4js and metacrs
organizations on github, as a precaution. Please let me know if you're ok
cloning the proj4js repo to github, and if I should do it in the proj4js or
the metacrs organization. Also get in touch with me to become an owner of
these organizations on github.

Andreas.
