Project Summery

When a pipeline route meets a river or a canal, the real story isn’t only on land—it’s under the water surface.
For the Cikampek–Plumpang BBM (fuel) pipeline corridor in West Java, Karta Bhumi carried out a bathymetric survey to capture what can’t be seen by the naked eye: the underwater terrain (riverbed/canal bed), depth variations, and channel geometry at key crossing points. This underwater “map” becomes a practical foundation for safer, smarter, and more efficient engineering design.
Survey Coverage
This work focused on four key waterway crossings in West Java:
-KP 11+200 – Walahar River
-KP 41+500 – West Tarum Main Canal (Saluran Induk Tarum Barat)
-KP 71+100 – CBL Canal (Cikarang Bekasi Laut)
-KP 81+400 – East Flood Canal (Banjir Kanal Timur / BKT) 
How We Collected the Data
To keep the results accurate and engineering-ready, the survey combined:
-Static GNSS control points for a strong reference system (UTM 48S / SRGI 2013 / EGM2008)
-RTK GNSS topography to map canal/river banks and nearby features
-USV + Single Beam Echo Sounder (SBES) to measure depths efficiently and safely, including calibration and corrections (barcheck, draft, and water level adjustment).
What We Delivered (Engineering-Ready Outputs)
Instead of just “depth numbers,” the survey outputs were prepared for practical design use:
-DTM (Digital Terrain Model) combining topography + bathymetry
-Contour maps at 1:1,000 scale with 0.5 m contour interval
-Long section (longitudinal profile)
-Cross sections every 5 meters across the channel 
These deliverables help engineering teams visualize the crossing clearly—almost like “seeing” the riverbed without diving.
With accurate bathymetric data, pipeline crossing design becomes more than an assumption—it becomes a decision backed by real measurements. Karta Bhumi is ready to support your infrastructure and industrial projects with reliable GNSS, topographic, and bathymetric surveys, delivering outputs that are clear, engineering-ready, and easy to use.

Topographic Survey for the Kali Bekasi River Boundaries, Bekasi
Who would have thought that beneath the bustling traffic of Bekasi City lies a large river that serves as the lifeblood of the city's flood control system? This river not only channels rainwater and surface runoff, but also plays a vital role in the ecological system, maintaining environmental balance.
Unfortunately, the increasing density of development along the riverbanks has blurred the boundaries of the Bekasi River. Many buildings are standing too close, green spaces are shrinking, and water flow capacity is decreasing. As a result, the risk of flooding increases year after year.
So, how can we re-manage river spaces to keep them safe, functional, and sustainable?
The answer: seeing rivers from the air using modern geospatial technology
 🛰️ Seeing Rivers with Centimeter Accuracy
Imagine:
- A drone flies low over the river, capturing thousands of high-resolution (5 cm/pixel) photos.
- A sonar instrument on an unmanned watercraft (USV) measures the depth of the riverbed with centimeter accuracy.
- Meanwhile, a GNSS instrument on land determines the position and elevation of each point with geodetic precision.
All this data is combined in processing software. The result? Not just a map, but a realistic picture of the current condition of the river and its banks, which can serve as a scientific basis for smarter urban spatial planning. This includes high-resolution (5 cm/pixel) orthophoto data, 0.5 m contour maps, and detailed river cross-sectional profiles, all of which serve as the basis for spatial planning of river boundaries and flood mitigation in the Bekasi area.
🌱 Data Speaks: From Images to Policy
The data generated from this survey is incredibly rich in information.Orthophoto maps with a resolution of 5 cm/pixel can clearly show buildings that are too close to the river, changes in riverbank lines, and even lost vegetation. From the DTM and cross-sections, planners can analyze the potential for flooding during the rainy season and identify critical points that need reinforcement or restoration.
💡 Why Is This Important for Cities and Residents?
- Maintaining riverbanks is not just the government's responsibility, but a matter for all of us
- When river boundaries are properly defined, flooding can be controlled because water has room to flow freely.
- Environmental quality improves because natural vegetation along the boundaries acts as a natural filter.
- Communities are safer because they no longer live in high-risk zones.
- City planning is more efficient because it is based on valid and up-to-date spatial data.
This project also demonstrates that innovative geospatial technology can help maintain a balance between development and environmental sustainability. This technology not only produces maps but also presents a new direction in environmental management based on spatial data.

Topographic Survey for the Way Garuntang and Way Balau River Boundaries, Lampung
PT Karta Bhumi Nusantara, along with its implementing team, successfully completed a topographic survey of the Way Garuntang and Way Balau River boundaries in Bandar Lampung City, Lampung Province. This survey was conducted to obtain high-precision spatial data that can be used as a basis for determining river boundaries along approximately 26.9 km. Given the river's location across an urban area with a relatively high population density, this survey plays a crucial role in the development of spatial planning policies, flood control, and the protection of protected areas along the riverbanks.
The methodology applied in this survey utilized UAV LiDAR technology for detailed elevation data acquisition and GNSS RTK for ground control point (GCP) measurements, which serve to bind and validate the LiDAR data. The combination of these two methods resulted in the acquisition of precise topographic data, both in the form of 0.5-meter interval contours and digital surface models (DSMs) and digital elevation models (DEMs). The advantage of UAV LiDAR is that it allows for dense vegetation penetration along riverbanks, allowing for a clearer understanding of the underlying morphology of the land.
The mapping scope not only focuses on the main river channel but also includes the banks on both sides of the river, which are included in the riparian area. The data obtained is used to produce detailed topographic maps, cross-sections at specific intervals, and long sections along the river alignment. This information is crucial for identifying changes in river channel geometry, potential erosion, critical landslide points, and areas prone to flooding. Thus, the survey results provide a comprehensive picture of the existing condition of the river and surrounding land.
The main problem faced in this area is the high pressure of human activities along the riverbanks, ranging from settlements and economic activities to waste disposal. This often leads to flooding, siltation, and reduced environmental quality. With this survey data, the local government and relevant technical agencies have a strong basis for establishing riparian lines in accordance with regulations and developing disaster mitigation programs based on current data.
In addition to technical and environmental aspects, the survey results also contribute to the development of regional medium-term development planning documents (RPJMD), detailed spatial planning plans (RDTR), and flood control master plans in the Bandar Lampung urban area.
With UAV LiDAR and GNSS RTK technology-based solutions, PT Karta Bhumi Nusantara is able to provide accurate, fast, and comprehensive data to support the needs of both the government and the private sector in river management. This work not only produces maps and topographic models but also serves as a crucial instrument in efforts to maintain ecological balance and sustainable development in the Lampung urban area. With valid data, it is hoped that decision-making can be more targeted, effective, and oriented towards environmental sustainability.

Topographic Survey for mining area - Muara Enim Regency
PT Karta Bhumi Nusantara has completed an integrated topographic survey using UAV LiDAR, photogrammetry, and bathymetry in the PT Manambang Muara Enim concession area in South Sumatra. This activity focused on three main rivers: the Bangke River, the Mbiung River, and the Kiahaan River, which have complex morphological characteristics, combining open land, dense vegetation, and river bodies with varying depths.
Monitoring was carried out over approximately 89 hectares of land and approximately 22.5 hectares of river bodies. To obtain accurate data, the team installed control points (CPs) using static GNSS methods, followed by UAV LiDAR and photogrammetry data acquisition. The mapping results produced high-resolution aerial orthophotos with an accuracy of 2 cm per pixel, as well as LiDAR point clouds, which were then classified into ground, vegetation, and other objects.
In addition, bathymetric surveys using a USV equipped with a Garmin 585 Plus Single Beam Echo Sounder (SBES) sensor were conducted in the Mbiung and Kiahaan Rivers, while RTK GNSS methods were used in the Bangke River. The results were a riverbed elevation model, bathymetric maps, and longitudinal and cross-sectional profiles that provide details on depth, width, and bank conditions.
The resulting outputs included orthophoto maps, 0.5 m contour maps, digital elevation models, lengths and cross-sections, and coordinate descriptions of the watershed. All of this data has been integrated into the official coordinate system, allowing for direct use to support technical planning and hydrological modeling.
The survey results also revealed significant changes in the landscape from 2013 to 2024, primarily due to open-pit mining activities around the Bangke and Mbiung Rivers. These changes affected vegetation cover, sedimentation potential, and river hydrological patterns, making this updated spatial data crucial for environmental impact planning and mitigation.
By utilizing UAV LiDAR, RTK GNSS, and USV Bathymetry technology, PT Karta Bhumi Nusantara continues to deliver modern survey solutions that are accurate, efficient, and sustainable. The resulting data serves as a critical foundation for supporting air resource management, risk mitigation, and environmentally conscious infrastructure development in the Muara Enim region.

Photogrammetric surveying is a method of measuring and mapping the Earth's surface by analyzing aerial photographs or imagery taken from aircraft, drones (UAVs), or satellites. This technique utilizes principles of geometry and optics to transform two-dimensional images into three-dimensional spatial information, such as contours, elevations, and the position of objects on the ground. 
In practice, photogrammetric surveys are conducted by taking a series of overlapping photographs, which are then processed using specialized software to produce products such as orthophotos, digital elevation models (DEM/DTM/DSM), and topographic maps. This method is highly efficient for mapping large areas with a high degree of accuracy and is widely used in the fields of construction, transportation, forestry, mining, and regional planning.
