#56 | fixed | Sort out handling of geoid | ||
Description |
Currently the altitude of GPS fixes and hence of cave entrances attached to them doesn't match the altitude of terrain from DEM files very well - the difference seems to be a few 10s of metres. Newer versions of proj have support for geoids, which should solve this: https://trac.osgeo.org/proj/wiki/VerticalDatums I think proj >= 4.8.0 is needed - the release announcement for it includes "Added preliminary vertical datum support". That was released 2012-03-14, so shouldn't be an unreasonable requirement. It would be good to coordinate how vertical datums are handled with therion, but they didn't respond to my email to their list about doing so. |

#58 | wontfix | About box photo missing on OS X | ||
Description |
Phil Maynard reports that on 10.6.8 the about dialog throws up an assertion failure when opened: ../src/osx/core/bitmap.cpp(1501): assert "IsOK()" failed in GetHeight(): invalid bitmap If you answer "No" to "Do you want to stop the program?" you get the about dialog, but the cave image is missing (only image is the aven icon).
This sounds like it is failing to load That leaves the question of why the image is failing to load. I tested the about dialog worked on OS X at some point between 1.2.18 and 1.2.19, and didn't get this assertion, so it may be related to the OS X version, or to changes after that. |

#64 | fixed | Terrain loading fails on Windows | ||
Description |
Jenny was unable to get terrain to load, instead just getting a grey disk at altitude 0. I've fixed the error checking for 1.2.20, so it now actually fails, but the inability to load terrain remains. My attempts to debug suggest that the wxZipInputStream class always fails to read anything, returning an unhelpful "generic read error". |
