Perspecta Labs would like to announce public availability of the Height
Map Reference Node Group Mobility (HM-RNGM) model for the BonnMotion
mobility generator.
The HM-RNGM model is based on the Reference Point Group Mobility Model
(RPGM). HM-RNGM enhances RPGM by adding support for limited 3D mobility
by calculating the height of the node at its new location on the terrain
and calculating node speed based on the 3D Euclidean distance to that
point. In addition, HM-RNGM allows node groups to be statically defined
in a configuration file. Finally, HM-RNGM allows the statically defined
group to follow a node as its reference point rather than creating an
abstract point that the nodes follow.
HM-RNGM works with a terrain file that defines the height of the terrain
at each location. The file must be readable by the GDAL library (e.g.,
GeoTIFF) and must define a spatial reference system that is convertible
to WGS84. The file must report height (values) in meters. HM-RNGM will
create mobility files whose x and y coordinates are meter offsets from
the origin of the terrain file in the direction of the terrain file's
projection.
HM-RNGM is currently maintained in a BonnMotion fork at:
https://github.com/perspectalabs/BonnMotion
Documentation is provided in:
doc/HeightMapRNGM/README.txt

(DARPA) under Contract No. HR0011-17-C-0047. Any opinions, findings,

DISTRIBUTION STATEMENT A. Approved for public release.
