Fledermaus 8.3.3 Release


We're pleased to present Fledermaus version 8.3.3. In this release, we provide improvements and important bug fixes. Read below for details.


  • We now support loading/importing surfaces in geographic coordinate systems that have cell sizes that were square in meters but not square in decimal degrees.
  • Improvements to the File > Export Scene to image to handle geographic coordianate system scenes.
  • It is now possible to invert in Z axes the vertical curtain images loaded in Fledermaus

Resolved Bugs

  • You are now able to work with a delimited area with the surface difference operation, the area has be predetermined as an object first.
  • There is better handling of reprojection on the fly for supported objects such as points and have operations work with the set Coordinate Reference System given there after.
  • QGF format objects (CAD files) now keep all edited parameters after importing them.
  • Contour dialog start and end values are interchangeable in increasing and decreasing, error given for testing start and end values was addressed 
  • Fixed occasional issues loading objects from a Qimera project coordinate reference system (CRS) when the scene and objects was the same but named differently.
  • Transparency settings on presentation slides are now persistent between different working scene sessions.
  • The resulting image from the Scene to Image functionality, no longer has any padding along the right/top edges in the resulting image.
  • Exported Scene to Image, when working with a very large resolution a shift was addressed.
  • When points are modified with the vertical offset attribute, the offset now applies to point labels if present.
  • Surface difference data inclusions are now addressed, requiring user input as to how they will be handled
  • The surface gridder and point importer now handle ascii files with NaN (not a number) values skipping over those records.
  • Import QPDs as .points now handles RGB values in the QPD files properly
  • Fixed issue with loading vertical curtains zooms and edits.
