#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. |

#61 | fixed | Units option on *calibrate | ||
Description |
Currently the calibrate adjusts for the offset then multiplies by the scale factor, which works for a stretched tape with the end missing *calibrate tape 0.05 0.752 But of things like mounting a DistoX in a waterproof case the offset will be measured with another device so will not want scaling Suggestion is to allow the addition of units to the offset if the scale factor should not be applied, this should allow the original format to continue to work while adding functionality. if not units real = ( reading - offset) * scale
If units eg real = reading * scale - offset |
