Comments

It is recommended the new QPS Geodetics Package 4.2.0 be installed before Fledermaus 8.8 (as well as Qinsy 9.8 and Qimera 2.8)

Fledermaus 8.9.1 is out now!

  • Fixed an issue when importing a TIFF as image where the CRS was not being set.
  • Fixed an issue with the cross profile export to ASCII where the profile docks visibility was not being used correctly.
  • And more bug fixes!  See Release Notes for more details.

FMGT 7.11.3 and FMMW 7.9.6 are ready for download!

  • Supports the new .DB and .QPD versions for the upcoming Qinsy 9.8.0 and Qimera 2.8.0 releases.
  • EPSG database updated to the current version 12.025.
  • New License Manager version 1.10.2.

Other Notes:

  • FMGT projects created in previous versions (version 7.10.3 or earlier) will need to manually have the Adjust flag cleared to continue with new processing, such as Mosaic, Statistics / Grid, or ARA layers.
