The ellipsoid used is Clarke 1866. The semi-major axis of the ellipsoid used is 6378206.4. The flattening of the ellipsoid used is 1/294.98." | |

| Apr 10, 2017 at 22:13 | comment | added | johnsankey | QGIS 2.0.1 says it won't instal beyond OSX 10.6.8, but when I copied the app into Applications, it runs. However, the problem I encountered with 1.8 remains. Perhaps I should mention that all my prior use of QGIS has been small scale using UTM; this is the first time I've tried a large scale project. | |
| Apr 10, 2017 at 20:43 | comment | added | johnsankey | ndawson: the recent upgrade says it only works with OSX 10.9 and before; I tried anyway and it did indeed not work. My son installed an early-2. version; I'll try to get a copy from him to see if that fixes the problem. | |
| Apr 10, 2017 at 20:39 | comment | added | johnsankey | AndreJ: I've cut all the outlines to NA only - the problem still exists. I can't reproject to equalarea because I have to edit the tree ranges with data that comes in WGS84 degrees. | |
| Apr 10, 2017 at 8:41 | comment | added | ndawson | Are you sure you mean 1.8? That's an ancient version and I'd strongly suggest upgrading. | |
| Apr 10, 2017 at 5:42 | comment | added | AndreJ | I can not reproduce your error with recent versions of QGIS. It might help if you cut the continent outlines to North America before reprojecting them to laea under a different filename, instead of using OTF. | |
