Anyone know of a good reference (either pay or open-web) that details recommended country projections?
Try the EPSG Geodetic Parameter Dataset which is more up-to-date and where epsg.io got its information.
Admittedly, it doesn't always have projected coordinate reference systems that are suitable for an entire country--but only because no one's told us what is used for a map of the entire country!
Spatial Reference allows user-contributions so might have more information.
Disclosure: I'm on the subcommittee that maintains it.
Try epsg.io. You can type in the name of a country or even search by CRS. And it is free!
There is also a source called Coordinate Reference Systems (CRS) of European Countries
- descriptions of Coordinate Reference Systems
- transformation parameters to pan-European CRS ETRS89, EVRF2000 and EVRF2007
- verification data for transformation
- online-transformation of single points for position and height from national CRS of a country to pan-European CRS ETRS89, EVRF2000 and EVRF2007 for test and verification purposes
To get the information select a country in the list or click on the corresponding red dot in the map
Try http://projectionwizard.org/ which will allow you to define your area of interest and the distortion property you wish to conserve. It will then give you a suggestion of suitable projections. You can copy the prog.4 text or if you are an arcMap user, you can pick similar projections, then edit pre-defined coordinate systems to change the standard parallels and center of origins to approximate the recommendation.
