I work on a variety of projects that involves data in vector and raster format across a variety of different locations across the world. Most of this data is received from the client who has no knowledge of the coordinate system/projection used. After finding the location of the project I often have to try and find out the projection thats used so that I can align everything in "real-world" space. Up until now I have used a website Georepository which lets you place a point on a map and it then gives a list of possible projections, however this website hasn't worked for a few months.
Does anybody know of any other resources that could help?
In an ideal world I would like to navigate to the location in ArcMap using a basemap and then a list of suggested projections would be available under the Coordinate System tab in Data frame Properties but im guessing this is something ofr the ESRI Ideas page
Hi, it looks liked the Georepository site is working for me:
You can search by name or area in ArcMap data frame properties, coordinate system tab. There's also a PDF file in the documentation folder of the ArcGIS for Desktop installation which lists areas of use. Much of this information comes from the EPSG Geodetic Parameter Registry--which is where Georepository, spatialreferences.org, epsg.io also got their information.

Hi, another website (although Melita covers it well) that I have found since I have been having similar issues with Georepository is ProjFinder Yo
