I'm not sure how GCA et their altitude data, but I suspect it's from Google, as I know GSAK can get altitude data for geocaches via Google.
If you look at an existing cache page that's in the vicinity of where you might like to hide your cache, you cab then click on the map for that cache and turn on Terrain. For instance, looking at your cache ga10760 (
http://geocaching.com.au/cache/ga10760.gmap ), by clicking on the map on the cache description page, and ticking the terrain checkbox in the upper right hand corner, will display the map like this:
https://farm5.staticflickr.com/4547/390 ... 6508_h.jpgThis level of zoom is as close as you can zoom in before the terrain rings disappear, but it shows elevations at every 20 metres ASL.
You could also create a new cache listing, and just keep it in draft status. You could then play around with likely coordinates and save the listing, allowing you to view the elevation when you view the listing page.
