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
