Undet project creation with Undet Indexer

First, to import point cloud data into Ares Commander you need to create an Undet project with Undet Indexer.

Undet Indexer is standalone software to create an Undet project file from a wide range of scanners or scan data files. An Undet project database is created to handle massive point clouds and allow efficient management.

Supported formats *.E57, *.FLS, *.RCP, *.PTX,  *.ZFS,*.LAS, *.LAZ, *.PTS, *.DP, *.FPR, *.LSPROJ, *.FWS, *.CL3, *.CLR, *.RSP, ASCII / NEZ (X,Y,Z/i/RGB).

To open Undet Indexer in Undet Project Management toolbar click

.

The indexer window will appear before importing scan data, first you must select the project type based on your scan data set:

  • LiDAR data management and analysis (The most common choice for large airborne LiDAR projects)
  • Topography, Corridor mapping, 3D city modeling (The most common choice for infrastructure projects)
  • Buildings, Infrastructure objects, Plants (The most common choice for terrestrial scanners)
  • Detailed scanned objects (The most common choice for small detailed objects such as monuments, parts of buildings or areas with a footprint up to 100m2)


The Undet database has a double-file structure – Preview points and Full points. Selecting the right project type speeds up the indexing process, without losing full point cloud points and affects only the preview view. Preview points are created from all imported scan data by using GRID, its size depends on the selected project type. The default GRID size for each project is chosen for optimal indexing speed and faster preview navigation to find a place to load all points using the “clipping box”.


Undet loads all points in the “clipping box” when the point count is less than the maximum point count. The maximum point count can be set manually in the Undet Density settings according to your system hardware parameters. If your clipping box is too big to load all points you will only see the preview points.

Default “max point count” settings:

Undet for Ares Commander Interval from 8 – 24 million points [can be tuned with performance slider]

LiDAR data management and analysis (The most common choice for large airborne LiDAR projects)

Preview points grid – 100 x 100 cm

Topography, corridor mapping, 3D city modeling (The most common choice for infrastructure projects)

Preview points grid – 30 x 30 cm

Buildings, Infrastructure objects, Plants (The most common choice for terrestrial scanners)

Preview points grid – 3 x 3 cm

Detailed scanned objects (The most common choice for small detailed objects such as monuments, parts of buildings or areas with a footprint up to 100m2)

Preview points grid – 1 x 1 cm

Note regarding Undet project creation:

Selecting the right project type speeds up the indexing process, without losing full point cloud points and affects only the preview view.
