ABOUT GEOCUE
GeoCue was founded in 2003 by a group of engineers with extensive experience in developing hardware
and software solutions for primary remote-sensed data acquisition. Our initial products were aimed at
reducing schedule and cost risk in geospatial production workflows by providing organizational,
productivity and data management tools for base geospatial data production. These tools have been
realized as the GeoCue product family. Today GeoCue workflow management tools are used by a
majority of North American geospatial production shops. In 2005, GeoCue began selling and supporting
Terrasolid tools for kinematic LiDAR data production. This was followed in 2009 by our acquisition of
QCoherent Software LLC, the creator of the point cloud exploitation toolset, LP360. Today GeoCue is
the largest supplier of kinematic LiDAR processing tools in North America and LP360 is the world’s
most widely used tool for exploiting point cloud data. In 2014, GeoCue started a division focused on
using small Unmanned Aerial Systems for high accuracy mapping. Leveraging our expertise in
production, risk reduction, and point cloud processing tools, we are continuing to bring new services
and products to market to provide surveyors and other geomatics professionals exciting tools for
geospatial data extraction using low-cost drones including Loki, our plug-and-play PPK direct
positioning system, and now our TrueView LiDAR/Imagery fusion (3DIS) sensors. To learn more, visit

ABOUT LP360 DRONE
LP360 is a 64-bit Windows® desktop application used for many years by the LP360 Geospatial
community for processing traditional aerial, mobile, and terrestrial tripod laser scanner data. The LP360
Drone community is the focus of this Users Guide containing the LP360 workflows for processing and
exploiting TrueView, microdrones® and guest sensor drone data. Formerly called TrueView EVO, LP360
Drone, is GeoCue’s LP360 point cloud exploitation product with the addition of a collection of tools and
workflows for processing drone data. LP360 Drone is the software used to post-process your raw flight
data to generate a 3D LiDAR point cloud in LAS format, colorize the point cloud, and geotag the images
collected. LP360 also has many tools for assessing and processing point cloud data, such as accuracy
assessment, automatic and manual ground classification, and contour/ surface generation. LP360
Drone is available in the following licensing levels:
•LPViewer – A free viewer level of LP360 for viewing a point cloud.
•TrueView EVO/LP360 Drone Explorer – A low-cost inspector license equivalent to LP360
Viewer, with Image Explorer enabled for viewing True Pose® photos, and Import TrueView
Cycle for field QC checks. This is also the license that should be purchased for delivery with
LP360 Explorer Packages provided to end users so they can make full use of the TrueView 3DIS
point cloud and photos, plus any derivative products you generate for them.
•LP360 Drone – Enables PPK processing for guest systems, such as the DJI P4RTK plus
TrueView 2DIS and 3DIS. This is the next generation ASPSuite Advanced and is equivalent to
LP360 Standard with the addition of the TrueView workflow tools and tools for ground
classification and volumetric computations. It is limited to product areas of no more than 10
km2of LAS data. Available as an annual subscription or a perpetual license.
•LP360 Drone+Fast Photo – Enables local Fast Orthomapping at a lower resolution, local
Orthomapping processing if you have your own Metashape license, and Cloud based
Orthomapping (using TrueView points). Available as an annual subscription or a perpetual
license.
•LP360 Drone+Cloud Photo 3000 – Enables local Fast Orthomapping, local Orthomapping
processing if you have your own Metashape license, and Cloud based Orthomapping (includes
3000 photos per month, additional photos may be processed using TrueView points). Available
as an annual subscription or a perpetual license.
•LP360 Drone+Strip Align – Enables Strip Align tools for adjusting for dynamic trajectory errors
in the dataset. Available as an annual subscription or a perpetual license.
•LP360 Drone+Business Intelligence Tools – Enables specific point cloud tasks designed for
extraction of non-ground features, such as rail, power lines, buildings, trees. Available as an
annual subscription or a perpetual license.
•LP360 Drone+Unlimited – this is the same functionally as LP360 Drone with the size limit
removed. Available as an annual subscription or a perpetual license.
The legacy TrueView EVO license levels are:
•TrueView EVO, formerly named TrueView EVO Lite – Enables PPK processing for guest
systems, such as the DJI P4RTK. This is the next generation ASPSuite Advanced and is
equivalent to LP360 Advanced with the addition of the TrueView workflow tools. It is limited to
product areas of no more than 10 km2of LAS data.

•TrueView EVO 3DIS, formerly named TrueView EVO – This is equivalent to LP360 Advanced
with the addition of the TrueView workflow tools. It is limited to product areas of no more than
10 km2of LAS data.
•TrueView EVO Unlimited – this is the same functionally as TrueView EVO with the size limit
removed. Available as an annual subscription.
ABOUT TRUEVIEW RECKON
TrueView Reckon is an Amazon Web Services (AWS) hosted platform that is used for a variety of
purposes in TrueView (and other) workflows. It provides services such as (items marked with a $T are
extra cost, paid in TrueView Points):
•Project data hosting and visualization ($T)
•Data archival ($T)
•Management and automatic delivery of sensor calibration files
•Automatic sensor health check
•Transfer of sensor Cycle data to GeoCue for technical support
•Management of TrueView Points for services that are paid via a metering scheme (marked in
this list with $T)
•Transaction history of sensor usage
•other related services
TrueView Reckon is accessed from within LP360 Drone in various workflows. These workflows might
require an LP360 Drone user to provide their Reckon login credentials. TrueView Reckon also has a web
interface for data visualization and account monitoring.
Every customer with a TrueView or guest sensor (whether purchased or a rental) is provided a Reckon
account.
A TRUEVIEW CYCLE
All TrueView sensors running the latest firmware, write their various data streams to a standard file
folder structure called a “Cycle” on the UMS (UMS Mass Storage). The original meaning of cycle was an
on/off cycle of the sensor. It is possible to have multiple collections (flights, in the case of a drone) in a
single Cycle, so it is not necessarily correct to think of Cycle as being synonymous with flight, though it
is typically.

UMS drive
The TrueView 655/660 Series includes one approved UMS drive with the capacity of 32GB or 64GB flash
storage that is proven to have a maximum transfer speed of the USB 3 technology. It is important to
only use GeoCue approved UMS drives to make sure the transfer speed is correct, and the data is
collected.
FAT32 and NTFS are supported formats for the UMS. GeoCue recommends using NTFS to avoid issues
with data transfer of files exceeding 4GB. If formatting is needed, please use the native Windows tool
and select NTFS as the format.

WARNING
Back up your data after every flight. Always use a clean UMS drive for every flight to make sure
sufficient space is available and the UMS drive is not corrupted.

Multifunction button
The multifunction button can be used to start/stop data collection or to abort an operation following
the combinations below:
Button Press Type Payload Reaction LED Readout
Short press
Start data collection if payload is
initialized (SYS LED is solid green).
SYS LED will switch to a slow
blink green to indicate data
collection started.
Long press
(5 seconds)
Terminate and delete current
data including log files.
Note: This can be triggered at any
state of the payload initialization.
SYS LED will fast blink yellow
followed by solid white.
Note: Once SYS is solid white
payload can be turned OFF.
Short press
(after collecting
data started)
Switch to stop collecting phase and
start downloading data to UMS.
SYS LED will switch to slow
blink white followed by solid
white or red error state.
Note: Payload can be turned
OFF once either solid white or
error state SYS LED is on.
