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 8.8.1 is out now!

  • Added the ability to use Ctrl+F on grid layers, so they can be quickly located in the file explorer.
  • Added support for loading routes from disk, improving persistence and reuse of routes.

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.

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.

Fledermaus 8.7.2 is now available!

  • Improved support for Space Navigator devices.
  • Updated a library that had a security vulnerability which was used for video display.

Fledermaus 8.7.0 is out now on all platforms!

  • EOMAP, connect to the EOMAP service that provides satellite derived bathymetry. Fledermaus provides the option to easily import the imagery and allows for gridding of the XYZ files provided by EOMAP. An account with EOMAP is needed.

  • Multilayer Grid, support has been added for multilayer grids from Qinsy. Different layers can be selected and viewed.

  • WMS import, imagery from a WMS server can be loaded into Fledermaus as background data.

  • Cable/Pipe view, for easier reviewing of cable/pipe lines, which centers the view on the cable/pipe and allows for stepping along the route.

  • Cable/Pipe X Point Listing, import cable/pipe objects and their associated cross point listing files for cable/pipe line review.

  • Dynamic points, allows points associated with a dynamic grid to be dynamically loaded inside a rectangle and played back in time, following a predefined track or navigation line.
