[sr.org] SHAPEFILE PROJECTIONFINDER

Hi manfred (and others),
That's a good starting point !
But indeed, epsg.io do not answer my change request on their site, about a
projection that seems to be incorrect for @bbrala on proj4. May be I need
to wait a little more, or create a pull request.
Their spatial reference is the same data as proj4, a big file with any defs.
I don't really like it, that why I propose on the main discussion list to
start a git for that.
What do you think of it ?
Regards,
julien2512

> http://www.egger-gis.at/shapefile-projectionfinder/

> There are two problems to solve before tools like SHAPEFILE
> PROJECTIONFINDER can be developed as a sustainable solution:
>
> 1. Until today there is no stable free service running like
> www.projfinder.com by Aaron Racicot, which can be used by all developers.
>
> 2. Until today there is no open source database which includes all
> coordinate system with epsg-code and additionally user and esri definded
> grids.
>
> There are open source solutions like:
>
> - spatialrefrence.org
> - epsg.io
>
> But in the detail both solutions have problems to update their database
> with low costs.
>
> Maybe OSGeo can promote a stable service with load balancing on the base
> of an existing solution like epsg.io including Aarons idea?
>
> Maybe organisation like UN, a university or EU (INTERREG) are possible
> project partners/sponsors for such a solution?
>
> The goal is: Tools like SHAPEFILE PROJECTIONFINDER, a Q-GIS-Plugin or a
> mobile application can use a stable free gis-service updated daily and help
> gis users to solve projection troubles faster. I think gis users working
> not everyday with gis will be happy about this solutions?
