2018-04-13Fix segfault in deformationKristian Evers
When transforming coordinates outside the grid model the deformation operation failed spectatularly. This is now fixed by checking that the coordinate is inside the grid. If it isn't an error is returned and a debugging log message is issued. Closes #934
2018-04-13Always ignore out-commented lines in cctKristian Evers
Previous to this commit cct would return the following $ cct -c 2,3,4 -t 0 -I +proj=cart +ellps=GRS80 BLAH 3579685.56545 508396.50343 5236837.50646 8.0832413787 55.5578176654 99.9833 0.0000 8.0832413787 55.5578176654 99.9833 0.0000 where the second input should not be parsed as a valid coordinate. With this commit that no longer happens and the input is returned verbatim back to the user. Closes #932

2018-04-12Move logging functions to proj.h APIKristian Evers
2018-04-12Add --skip-lines option to cctKristian Evers
With this it is possible to skip the header when transforming coordinates from a file.

2018-04-12Fix: use proper double epsilon declarationJavier Goizueta
2018-04-12Enhance the precision of Spherical Mercator projection near the equatorJavier Goizueta
This uses a linear approximation of tan(x+pi/4) for better precision at small latitudes. As a result points of latitude 0 maintain a 0 Y coordinate and 0,0 is transformed to 0,0

Previously when calling cct without any arguments the following message would be presented to the user: cct: Bad transformation arguments - ((null)) 'cct -h' for help With this change the help instructions are returned instead.

2018-03-27Change units of axisswap to 'whatever'Kristian Evers
Since units are validated during pipeline setup we need to make sure that axisswap can be used for more than just projected outputs.
2018-03-27Validate that units match between pipeline stepsKristian Evers
As suggested in [0], steps in a pipeline are now checked for compliance. If the right side units in step n differ from the left side units in step n+1 the pipeline can't be constructed and an error is raised. [0] https://lists.osgeo.org/pipermail/grass-dev/2018-March/088123.html
