#26 closed enhancement (wontfix)

please let people find their EPSG on the web

Reported by: timmie Owned by: grass-dev@…
Priority: trivial Milestone: 7.4.1
Component: wxGUI Version: unspecified
Keywords: wxgui, location-wizard Cc:
CPU: Unspecified Platform: Unspecified

Description

Maybe a link to http://spatialreference.org/ could be added to the location wizard.

A extra button: "Look-Up your EPSG-code on the web". This button could link to the above mentioned address. Also a explanation why or what the EPSG-code is good for (the Mapserver docs have nice examples) would be nice. Many migrating users would never have heard of EPSG...

Experienced users will appreciate when working with other projections...

Replying to timmie:

Copied from grass-dev ML by Hamish:

A nice idea, albeit subject to volatility of some else's website. Link the button to something we control like a page GRASS's wiki or OSGeo's wiki or grass's osgeo web pages? Then old versions don't have hardcoded deal links one day.

Also a explanation why or what the EPSG-code is good for (the Mapserver docs have nice examples) would be nice. Many migrating users would never have heard of EPSG...

mouse-over tooltip?

From grass-dev ML by Michael Barton:

I echo Hamish's sentiments below. The page is nice, but I worry about hardcoding a link to a URL that we don't control. Also, GRASS (i.e., PROJ) can only read epsg codes that are in the database that comes with GRASS. I don't know if we can depend on the web version and local versions being the same.

Re explanation of EPSG codes, we need a help manual for the location wizard. There are other aspects that need to be explained too. The new GUI is still under development and we are very grateful for any who are taking the time to test it. We also welcome any assistance--eg. Creating the html pages for location manager help. We could then add help buttons to pages.

Milestone: 6.4.07.1.0
Platform: Unspecified
Priority: minortrivial

For the record: http://epsg.io/

http://epsg.io/ is much newer than http://spatialreference.org/ and nicer (more user friendly) than http://www.epsg-registry.org/. This also shows what changed and what not (old link works after 7 years but we might want to change it to something else now which we again don't know how stable it will be).

Creating a manual page on that topic with (external) links to these three websites is a good idea, I think, and links in the GUI wouldn't be so bad. We can add there more than one to increase the probability that at least one of them works.

Anyway, GUI does not prevent people from opening browser and finding one of these web pages online using their judgment, so downgrading priority to trivial.
