Bounds on the Map: zoom to + highlight the area of transformation

[klokan]

The Map page (e.g. /4326/coordinates) should display bounds of transformation - and zoom the these by default. (now the zoom is fixed :-().

The bounds should be passed instead of the center lon/lat from the HTML to JavaScript.

For displaying the bounds on the map we may use the trick similar to http://www.kartenportal.ch/kartensammlungen/ - as it is described at:

Related to #4 - the list of transformations and their bounds may be passed into JavaScript - instead of only single bounds.

Bounds (both WGS 84 and projected) should also be available as text output.

@tormi Please create a new ticket for this idea - with more details about what you have in mind. I am not sure if what you want is directly related to this ticket.

I expect you have in mind an interface similar to: http://boundingbox.klokantech.com/. Correct?

It may be challenging for non-WGS84 - in some projections the border lines may be curved, and the rectangle degraded to general polygon. It would be doable only with Proj4js and only for subset of coordinate systems.

Note: The transformations and coordinate systems in EPSG database have only link to an Area. Area has a universal bounds only in WGS84. There is no record for projected bounds of a coordinate system in the official database - we would need to handle it with our own external database - if you want bounds such as these used for generating tile pyramids in WMTS for given coordinate system.

BTW feel free to contribute with a pull request - EPSG.io is an open source project.

Ok

Correct, I meant bounding box coordinates as in http://spatialreference.org/ref/epsg/4326/

Wow, already implemented :) Thanks!
