            Bug ID: 332108
           Summary: Read/write gx:altitudeMode for KML LookAt tags
    Classification: Unclassified
           Product: marble
           Version: 1.7 (KDE 4.12)
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: google-code-in, junior-jobs
          Severity: task
          Priority: NOR
         Component: general
          Assignee: marble-bugs at kde.org
          Reporter: earthwings at gentoo.org

The gx:altitudeMode should be read from and written to KML files inside the
LookAt tag. See
https://developers.google.com/kml/documentation/kmlreference?#lookat
- Move the altitudeMode getter and setter from GeoDataCamera up to
GeoDataAbstractView
- Change KmlaltitudeModeTagHandler to check for GeoDataAbstractView instead of
GeoDataCamera
- Write the altitude mode in KmlLookAtTagWriter just like KmlCameraTagWriter
does
- Add a <gx:altitudeMode>clampToSeaFloor</gx:altitudeMode> to
tests/data/LookAtTest.kml

Make sure to compile Marble with the following cmake options enabled:
BUILD_MARBLE_TESTS=TRUE, BUILD_MARBLE_TOOLS=TRUE. Execute
tests/TestGeoDataWriter and make sure no errors come up. Use tools/kml2kml to
analyze errors and fix the tag writers, if needed. Submit a review request at
https://git.reviewboard.kde.org with the marble group as reviewers.

Please leave a comment here (e.g. "I want to work on this task.") if you start
working on this task to avoid multiple people working on it at the same time.
