HxMap 4.6 Release Notes

Main features

• HxMap 3D Advanced module beta release - create 3D textured mesh and true ortho from Leica CityMapper systems

• TerrainMapper-3 support beta release - process datasets through the complete Lidar workflow

• Lidar workflow is improved for all Hyperion lidar sensors in TerrainMapper, CityMapper and CountryMapper systems

• Completed image seamlines can be added as references to a new project

• Blockwide radiometry supports oblique image display and radiometric normalization adjustment

• Lidar Viewer cross section custom depth setting and improved navigation

• Data Copy gives additional notifications in GUI when Allowable errors limit is reached

Main fixes

• Product generation Infocloud colorization on points could show horizontal offsets

• Product generation with units of us survey feet or intl. feet was scaled incorrectly

• Product generation JPG output for DMCIII hi-res aerial image

• Lidar Viewer blend intensity with color by take

• Data source selection memory usage reduced

• 3D Editor cut object with snapping created unneeded vertices

• 3D Editor ridge move after cut object

• Coordinate reference with parentheses in name could be assigned wrong ESPG code

Known Issues

• License checking over a VPN may take several minutes

Upgrade Notes

• HxMap 4.6 requires version 2.18.0 or higher of the Leica Client License Manager application to be installed before running. Ensure that it is installed on the license host, submitters and nodes for a distributed installation.

• Image ingest processing is commonized for all MFC150 based systems: CityMapper-2, TerrainMapper-2, DMC-4, ContentMapper, CountryMapper. Ingest parameters are estimated in a strip-wise fashion prior to full image processing.

• Lidar workflow improvements:

  • Calibration tool has been simplified, it is configured to compute Misalignment update by default. The [Hyperion Calibration] section of HxMap.ini is removed.

  • Calibration tool will add appropriate range offset and radiometric calibration values in case they are missing from the available calibration file for Hyperion sensors

  • Please compute a new misalignment update with calibration tool in HxMap 4.6 for each lidar sensor, before continuing with Ingest. Any existing flight data which was used to compute Misalignment can be selected.

  • The point cloud low noise filter has been moved from Point Cloud Classification tool to Point Cloud Filter tool and can be run separate from Ground Classification

• Export EOP tool in Product Generation perspective now takes Project as input instead of Block.

• First generation CityMapper (RCD30 with Hyperion 1) is no longer supported in Ingest.

• HxMap GeoData

  • Added German Combined Geoid 2016

  • Maroc_Zone_2 updated to match EPSG convention

  • Corrected definition of Krovak projection systems
