1. Introduction

Geodetic data processing plays a pivotal role in our ability to understand, manage, and preserve the Earth’s resources. As the foundation of modern geospatial applications, it allows us to accurately represent and analyze the Earth’s surface and the objects and features that exist on it. The data collected through satellite imagery, aerial photography, and surveying instruments is vital for various applications, including land surveying, mapping, navigation, environmental monitoring, and disaster management. The need for efficient and reliable geodetic data processing methods has grown significantly due to the increasing global population, rapid urbanization, and the urgency to address climate change. Accurate geodetic data is essential for informed decision-making as it helps in planning sustainable urban growth, assessing the impacts of climate change, and mitigating the effects of natural disasters.

Processing geodetic data presents several challenges, arising from the vast amounts of data collected from various sources, the inherent uncertainties and complexities associated with geospatial data, and the need for timely and accurate analysis. Traditional geodetic data processing methods rely on deterministic mathematical models and rigorous computational techniques to make sense of the data. In contrast, these methods have been effective in many cases, and they often struggle to handle the uncertainties and complexities in geodetic data. Some of the critical challenges in processing geodetic data include the following [1, 2]:

1. Data volume: The increasing availability of high-resolution satellite imagery and other geospatial data sources has led to significant growth in the volume of data that must be processed, stored, and analyzed.

2. Data quality: Geodetic data can be affected by various sources of error, including measurement errors, sensor limitations, and atmospheric disturbances. These errors introduce uncertainty and imprecision in the data, making it challenging to obtain accurate and reliable results.

3. Data integration: Geodetic data is often collected from multiple sources and in various formats, requiring effective data integration and fusion techniques to combine information and generate a coherent representation of the Earth’s surface.

4. Scalability: With the growing demand for geospatial information, there is a need for scalable processing methods that can efficiently handle large-scale datasets and provide timely results.

In response to these challenges, researchers have begun to explore alternative approaches to geodetic data processing, with soft computing techniques emerging as a promising option. Soft computing is an interdisciplinary field that encompasses several computational methodologies, including artificial neural networks (ANNs) [3, 4, 5], fuzzy logic, and evolutionary algorithms (EAs). These techniques are characterized by their ability to handle imprecise, uncertain, and incomplete information, making them well-suited for addressing the challenges associated with geodetic data processing. Soft computing techniques have demonstrated their potential in various geodetic data processing tasks such as satellite image classification [6], terrain modeling [7], and geoid determination [8, 9]. They are particularly effective in pattern recognition, learning from data, and optimizing complex problems. The flexibility and adaptability of soft computing techniques have made them an attractive alternative to traditional geodetic data processing methods, often leading to improved performance and more accurate results [10, 11]. In addition, soft computing techniques are often employed in conjunction with traditional geodetic data processing methods, resulting in hybrid approaches that leverage the strengths of both paradigms [12]. This combination allows for more robust and versatile solutions capable of tackling diverse challenges in the geodetic data processing.

Accordingly, the emergence of soft computing techniques in geodetic data processing offers a promising avenue for addressing the complexities and uncertainties inherent in geospatial data [13]. As researchers continue to explore and refine these techniques, it is expected to see significant advancements in understanding and managing the planet’s resources and addressing pressing global challenges such as climate change, natural disasters, and urbanization.

Figure 4.

Satellite and terrestrial geodetic data collection methods

Satellite imagery is a primary source of geodetic data and involves capturing images of the Earth’s surface using remote sensing satellites. These images provide valuable information about the Earth’s topography, land use, and vegetation patterns. Satellite imagery can be categorized based on spatial, spectral, and temporal resolutions. High-resolution satellite images, such as those provided by the Landsat and Sentinel programs, allow for identifying small features and more detailed analysis. In contrast, lower-resolution images, such as those from MODIS, are helpful for large-scale environmental monitoring and global change studies.

Aerial photography involves capturing images of the Earth’s surface from aircraft, balloons, or drones. Aerial photographs have been used for decades to collect geodetic data and can provide higher-resolution imagery compared to satellite imagery, allowing for a more detailed analysis of local features. Aerial photography can be either vertical, where the camera is oriented directly towards the ground, or oblique, where the camera is angled, providing a perspective view of the landscape. Advances in technology have led to the development of digital aerial cameras and photogrammetric techniques, which enable the extraction of accurate 3D information from overlapping aerial photographs.

Surveying instruments are essential tools for collecting geodetic data on the ground. Traditional instruments, such as total stations, measure angles and distances between points on the Earth’s surface, allowing for the accurate determination of positions, elevations, and other spatial information. The global positioning system (GPS) and other global navigation satellite systems (GNSS) have revolutionized geodetic data collection by providing precise positioning information using signals from orbiting satellites. Other surveying instruments, such as LiDAR (Light Detection and Ranging) and ground-penetrating radar (GPR), enable the collection of high-resolution topographic and subsurface data.

3.2 Applications of geodetic data processing

Geodetic data processing techniques are employed to determine precise positions and velocities, compute distances and directions, and generate land, air, and sea navigation routes. The development of real-time kinematic (RTK) GPS and other high-precision positioning techniques has greatly improved the accuracy and reliability of navigation systems, with wide-ranging applications in transportation, agriculture, and other industries.

Environmental monitoring is a crucial application of geodetic data processing that involves observing and analyzing changes in the Earth’s environment over time. Geodetic data processing techniques are employed to process satellite imagery, aerial photographs, and other geospatial data to assess land cover changes, deforestation, desertification, urbanization, and other environmental phenomena. Remote sensing and GIS technologies enable large-scale monitoring and analysis of environmental parameters, such as vegetation health, soil moisture, and water quality, essential for understanding the impacts of climate change and human activities on the Earth’s ecosystems and resources.

Disaster management is a critical application of geodetic data processing, which plays a vital role in the assessment, mitigation, and recovery phases of natural and human-induced disasters. Geodetic data processing techniques can be utilized to analyze and model hazard scenarios, such as earthquakes, landslides, floods, and wildfires, and to generate risk and vulnerability maps that inform emergency planning and response efforts. In the aftermath of disasters, satellite imagery, aerial photography, and other geospatial data can be rapidly processed to assess the extent of damage, prioritize recovery efforts, and monitor the progress of reconstruction activities.

However, geodetic data processing is essential for various applications, from land surveying and mapping to navigation, environmental monitoring, and disaster management. The various data collection methods, including satellite imagery, aerial photography, and surveying instruments, provide diverse and complementary sources of geospatial information that can be processed and analyzed using advanced techniques and technologies. As the field of geodetic data processing continues to evolve, the development and application of innovative approaches, such as soft computing techniques, will be crucial for addressing the complex challenges associated with collecting, analyzing, and interpreting geodetic data.

5. Advantages and limitations of soft computing techniques

Hard and soft computing techniques (Figure 7) are two distinct approaches to problem-solving in computer science and artificial intelligence. Both methods have advantages and applications, and often, a combination of the two is employed to find optimal solutions [55, 56, 57]. Hard or conventional computing is rooted in mathematical logic, precise algorithms, and deterministic models. This approach is characterized by its rigidity and strict adherence to predefined rules and instructions. It requires a well-defined problem, and its solutions are exact and reliable. In contrast, soft computing is a more flexible and adaptive approach that focuses on imprecision and uncertainty in problem-solving. Unlike hard computing, soft computing tolerates imprecise data and partial truth, making it suitable for handling complex, real-world problems [58].

Figure 7.

Hard and soft computing techniques.

The emergence of soft computing techniques has brought a new dimension to geodetic data processing, allowing for handling complex, imprecise, and uncertain data. These techniques have demonstrated their effectiveness in various geodetic data processing tasks. However, despite their potential, advantages and limitations are associated with using soft computing techniques. This section explores the benefits and challenges of using soft computing techniques in geodetic data processing, providing insight into the strengths and weaknesses of each approach [59, 60, 61, 62, 63]. By understanding these advantages and limitations, researchers can make informed decisions when selecting and applying soft computing techniques to geodetic data processing tasks if they comprehend these advantages and limitations.

5.1 Advantages

One of the primary advantages of soft computing techniques is their ability to handle imprecise, uncertain, and incomplete data. This is particularly important in geodetic data processing, as geospatial data often contains errors, uncertainties, and gaps due to sensor noise, measurement inaccuracies, and data loss during transmission. Soft computing techniques, such as artificial neural networks, fuzzy logic, and evolutionary algorithms, can effectively deal with these challenges by modeling and processing data flexibly and tolerantly. For example, fuzzy logic allows for representing and manipulating uncertain and imprecise data by extending traditional binary logic to incorporate the concept of partial truth. This enables the development of models and algorithms to better account for the inherent ambiguities and uncertainties in geodetic data. Similarly, artificial neural networks can learn and adapt to noisy or incomplete data by adjusting their internal weights and biases through iterative training, resulting in more robust and accurate models.

Soft computing techniques are known for their adaptability and flexibility, making them well-suited for addressing the diverse and dynamic challenges associated with geodetic data processing. Adjusting their parameters, architectures, and training strategies can easily be tailored to specific tasks and applications. In addition, soft computing techniques can often learn and adapt to new data and changing conditions, enabling them to maintain their performance even in the face of evolving problems and requirements. This adaptability and flexibility can be particularly valuable in geodetic data processing, where data volume, variety, and complexity are continuously increasing due to advancements in sensor technology and data collection methods.

5.2 Limitations

One of the main limitations of soft computing techniques is the computational cost associated with their implementation and execution. Many soft computing techniques, such as artificial neural networks and evolutionary algorithms, can be computationally intensive, mainly when dealing with large-scale datasets and complex models. This can lead to long training times, high memory requirements, and slow query response times, which can be prohibitive in some geodetic data processing scenarios, especially when real-time or near-real-time processing is required. To address this challenge, researchers have explored various strategies to improve the efficiency of soft computing techniques such as parallelization, algorithmic optimization, and hardware acceleration. However, further research and development are needed to ensure that soft computing techniques can be effectively applied to large-scale geodetic data processing tasks without compromising computational efficiency and performance.

Another limitation of soft computing techniques, particularly artificial neural networks, is their “black-box” nature, making it difficult to interpret and explain the underlying processes and decision-making. This lack of interpretability and explainability can be problematic in geodetic data processing applications, where understanding the rationale behind model predictions and decisions is crucial for validation, trust, and regulatory compliance.

Researchers have proposed various approaches to enhance the interpretability and explainability of soft computing techniques such as visualizing the internal states and activations of artificial neural networks, extracting rules from trained models, and developing hybrid models that combine soft computing techniques with more interpretable and explainable methods. Despite these efforts, further research is needed to develop more transparent and interpretable soft computing solutions for geodetic data processing, ensuring that they can be effectively integrated into decision-making processes and workflows.

6. Future directions and challenges

As geodetic data grows in volume and complexity, the need for more efficient algorithms becomes increasingly essential. Developing algorithms that can process large-scale datasets without compromising accuracy is crucial.

This can be achieved by incorporating expert knowledge into the design of model structures, objective functions, or constraints. For example, geodetic data processing constraints can be integrated into the optimization process of an evolutionary algorithm to ensure the generation of feasible solutions. Future research should explore methods for effectively incorporating domain-specific knowledge into soft computing techniques and assess the impact of such integration on the performance of geodetic data processing tasks. With the increasing availability of high-resolution satellite imagery and the proliferation of geospatial data sources, there is a growing need for improved data fusion and integration techniques. With their ability to handle imprecise and uncertain data, soft computing techniques are well-positioned to address this challenge. Future research should develop novel data fusion and integration techniques that effectively combine information from diverse sources, account for uncertainties and inconsistencies, and provide a comprehensive understanding of the geospatial phenomena under investigation. Integrating soft computing techniques with big data analytics can enable the processing and analysis of massive geodetic datasets, uncovering hidden patterns and relationships that were previously unattainable. Researchers should explore methods for efficiently integrating soft computing techniques into big data analytics frameworks and assess their effectiveness in handling large-scale geodetic data processing tasks. Cloud computing offers scalable computing resources, making it an ideal platform for processing geodetic data using soft computing techniques.

Developing and adopting standard protocols and benchmark datasets can help evaluate and compare different soft computing techniques in the geodetic data processing. Standardization can improve the reproducibility of research and promote the dissemination of best practices within the scientific community. Future studies should focus on establishing standardized evaluation metrics, protocols, and benchmark datasets for various geodetic data processing tasks, enabling researchers and practitioners to objectively assess the performance of different soft computing methods and identify areas for improvement. As soft computing techniques become increasingly crucial in geodetic data processing, there is a need for specialized education and training programs that equip geodesy professionals with the necessary skills and knowledge to apply these techniques in their work effectively. Universities and other educational institutions should consider developing curricula and training programs that combine geodesy, remote sensing, and geospatial sciences with artificial intelligence, machine learning, and soft computing. Additionally, short-term workshops and training courses can be organized to update existing professionals on the latest developments in the field.

With the increasing adoption of soft computing techniques in geodetic data processing, it is essential to consider the ethical implications of using these technologies. Ensuring transparency, fairness, and accountability in developing and applying soft computing models is crucial. Researchers should adhere to responsible AI principles and consider the potential societal impacts of their work, including potential biases in the data, the explainability of their models, and the environmental footprint of the computational resources required. Future studies should also explore methods for incorporating ethical considerations into designing and evaluating soft computing techniques in geodetic data processing.
