Forestry Survey Equipment in Sarawak Compass, Total Station or GNSS? Malaysia
Forestry Survey Equipment in Sarawak 鈥 Compass, Total Station or GNSS? Malaysia
What surveying equipment should you use for forestry work in Sarawak?
Should you choose a:
Surveying Compass?
Total Station?
GNSS / RTK?
or
Auto Level?
There is no single instrument that is best for every forestry survey.
The correct choice depends on one question:
What do you need to measure?
For preliminary direction and terrain observations, a professional surveying compass such as the Ushikata LS-25 may be suitable.
For coordinates, electronic distance, detailed topographic work or precise elevation, other surveying technologies become more appropriate.

Understanding this distinction prevents a common purchasing mistake:
Buying the instrument first and defining the measurement later.
1. Surveying Compass for Forestry
A professional surveying compass can be useful when a forestry team needs:
Direction
Magnetic bearing
Field orientation
Preliminary route investigation
Terrain reconnaissance
Portable field observations
A simple compass may be sufficient if only basic direction is required.
However, when the job requires more advanced field observations, a specialised surveying compass becomes relevant.
Ushikata LS-25 for Forestry Survey
The Ushikata LS-25 is a Japanese surveying compass / Level Tracon combining several field-survey functions.
Key capabilities include:
鉁 Magnetic direction & bearing
鉁 12脳 erect-image telescope
鉁 Horizontal angle measurement
鉁 Vertical angle measurement
鉁 Levelling capability
鉁 Stadia measurement
This places the LS-25 between a simple compass and more complex electronic surveying systems in terms of field functionality.
Why the 12脳 Telescope Matters in Forestry
Dense vegetation can make target identification difficult.
With an ordinary handheld compass, the operator primarily observes direction.
With the LS-25, the 12脳 telescope allows a defined target to be sighted.
Examples include:
Survey markers
Ranging poles
Selected trees
Reference points
Terrain features
Temporary survey targets
Correct target identification is essential.
A precise reading taken to the wrong target is still the wrong observation.
2. Total Station for Forestry Survey
A Total Station should be considered when the forestry project requires more precise and structured survey data.
Typical requirements include:
Electronic Distance Measurement
Precise angle measurement
Coordinates
Topographic survey
Traverse work
Detailed site measurement
Setting-out
A Total Station provides capabilities that the LS-25 does not.
When Should You Choose a Total Station Instead of LS-25?
Choose a Total Station when the question is:
鈥淲hat is the exact distance?鈥
鈥淲hat are the coordinates?鈥
鈥淲here should this point be set out?鈥
鈥淲e need detailed topographic data.鈥
Consider the LS-25 when the requirement is closer to:
鈥淲hat direction is that point?鈥
鈥淲hat is the bearing?鈥
鈥淲hat is the angle between these directions?鈥
鈥淲e need portable preliminary field observations.鈥
They solve different problems.
3. GNSS / RTK for Forestry Survey
GNSS / RTK technology is relevant when the forestry team needs coordinate-based positioning.
Potential applications include:
Coordinate collection
Georeferenced field points
Large-area positioning
Digital mapping
GIS workflows
Control-point work
Boundary-related field data where appropriate professional procedures are followed
For large areas, coordinate-based systems can dramatically improve digital data workflows.
Can GNSS Completely Replace a Surveying Compass?
Not necessarily.
The technologies provide different information.
A GNSS receiver answers:
鈥淲here am I?鈥
or
鈥淲hat are the coordinates of this point?鈥
A surveying compass can help answer:
鈥淲hat direction am I observing?鈥
A Total Station can help answer:
鈥淲hat is the precise angle and distance between survey points?鈥
In real projects, different instruments may be used during different phases.
4. Auto Level for Forestry & Infrastructure Work
An Auto Level is the correct category when the main requirement is elevation difference.
Examples include:
Forest-road level
Drainage level
Culvert work
Platform level
Infrastructure construction
Benchmark transfer
For these jobs, use an appropriate Auto Level + Levelling Staff.
MTM Precision supplies options including:
Myzox CL-28
Myzox CL-36
Topcon Auto Levels
5 m Levelling Staffs
Example 1: Preliminary Forest Route
A forestry team needs to walk through a proposed route and understand:
Direction
Terrain
Slope conditions
Relationship between field features
At this preliminary stage, a portable surveying compass such as the Ushikata LS-25 may be useful.
Once the route is selected, more detailed surveying may follow.
Example 2: Detailed Road Survey
The route has now been approved.
Engineers require:
Coordinates
Distances
Topography
Elevation
Construction information
The equipment requirement has changed.
The project may now require:
GNSS / RTK
Total Station
Auto Level
depending on the survey methodology.
This demonstrates an important principle:
One project can require several surveying instruments at different stages.
Example 3: Forest Research Team
A research team may need:
Direction observations
Terrain observations
Reference-target sighting
Vertical-angle information
but may not require construction-grade coordinate setting-out.
In this case, the LS-25 may provide a useful combination of functions without requiring a complete Total Station workflow.
Example 4: Coordinate Mapping
If the objective is to build a digital map with georeferenced field points, a surveying compass alone is insufficient.
The project requires a coordinate-positioning solution such as GNSS / RTK, potentially combined with other surveying equipment.
Do not buy an LS-25 expecting it to generate GPS coordinates.

Important: Magnetic Interference in Forestry Operations
The LS-25 uses magnetic direction measurement.
Do not take important compass observations immediately beside:
4WD vehicles
Logging trucks
Excavators
Steel equipment
Metal fencing
Heavy machinery
Large electrical equipment
These can potentially influence magnetic observations.
Move to a suitable observation location and repeat questionable readings.
Which Instrument Is More Accurate?
This question needs context.
Accuracy cannot be compared meaningfully without specifying what is being measured.
For example:
A GNSS system is designed for coordinate positioning.
A Total Station is designed for precise angle and distance survey.
An Auto Level is designed for levelling.
A surveying compass is designed around directional and relevant angular field observations.
Therefore, instead of asking:
鈥淲hich instrument is most accurate?鈥
ask:
鈥淲hich instrument provides the measurement and accuracy required for this project?鈥
Forestry Survey Equipment Buying Guide
Before buying equipment, define these requirements:
1. Direction / Bearing
Do you only need field orientation?
2. Horizontal Angle
Do you need the angle between selected directions?
3. Vertical Angle
Do you need slope-related observations?
4. Distance
Do you need approximate stadia information or precise electronic distance?
5. Coordinates
Do you need Easting, Northing or other coordinate data?
6. Elevation
Do you need accurate height differences?
7. Data Recording
Does the project require digital survey data?
8. Portability
How far must the equipment be carried into the field?
These answers determine the instrument category.
