dji MATRICE 4 Series - Linear Route

◆
Flying near surfaces without clear patterns or textures.
◆
Flying near surfaces with repeating identical patterns or textures (e.g., tiles
with the same design).
◆
Flying near obstacles with small surface areas (e.g., tree branches and power
lines).
• Keep the sensors clean at all times. DO NOT tamper with the sensors. DO NOT
use the aircraft in dusty or humid environments.
DSM Follow
By importing the DSM le, the app will generate a ight route with altitude changes. The
DSM les of the mapping area can be obtained using the following two methods:
Import Local File
• Collect the 2D data of the mapping area and perform a 2D reconstruction using DJI
Terra by selecting Fruit Tree mode. A .tif le will be generated and can be imported to
the microSD card of the remote controller.
• Download the terrain mapping data from a geobrowser.
Download from Internet
DSM les can be directly obtained by downloading the open source data of the ASTER
GDEM V3 geoid database.
• Make sure the DSM le is a geographic coordinate system le, not a projected
coordinate system le. Otherwise, the imported le may not be recognized. It is
recommended that the resolution of the imported le should be no more than
10 meters.
• Make sure that the mapping area is within the range of the DSM le.
• The open-source geoid database may have errors. DJI is not responsible for
the accuracy, authenticity, or validity of the data. Pay attention to the ight
environment and y with caution.
Linear Route
Linear Route is used to collect orthophotos for strip-shaped areas such as rivers and
pipelines. The mapping area can be generated by selecting the center line of the strip and
extending outward along this line.
