Maximising GIS Performance: Harnessing the Power of Parallel Processing

By Shahabuddin Amerudin

Introduction

Geographic Information System (GIS) projects often involve complex spatial analyses, large datasets, and computationally intensive tasks. To tackle these challenges efficiently, the use of parallel processing techniques has gained significant attention. This article explores the benefits of parallel processing in GIS projects, comparing commercial software offerings and referencing studies and reports to support the findings.

Background

Parallel processing refers to the simultaneous execution of multiple tasks or computations to speed up the processing time of a GIS project. In the context of GIS, parallel processing involves dividing a task into smaller subtasks that can be executed concurrently by multiple processor cores or threads, thereby increasing overall efficiency and reducing the time required to complete the project.

GIS projects often involve computationally intensive operations such as data processing, spatial analysis, and geoprocessing, which can benefit from parallel processing. By distributing these tasks across multiple cores or threads, parallel processing enables faster execution and improved performance.

How parallel processing works in a GIS project

  1. Task Decomposition: The GIS task is divided into smaller, independent subtasks. For example, if you are performing a spatial analysis on a large dataset, you can divide the dataset into smaller spatial units or regions.
  2. Task Assignment: Each subtask is assigned to a separate processor core or thread for execution. Modern processors with multiple cores or threads can handle several tasks simultaneously.
  3. Concurrent Execution: The assigned subtasks are processed concurrently, with each core or thread working on its allocated subtask independently. This allows multiple computations to be performed simultaneously.
  4. Communication and Synchronization: In some cases, subtasks may need to communicate and share intermediate results. Synchronization mechanisms are employed to ensure that dependencies between subtasks are properly managed.
  5. Aggregation of Results: Once all subtasks are completed, the results are combined or aggregated to obtain the final output or solution for the GIS project.

Parallel processing can significantly improve the performance of GIS projects, especially when dealing with large datasets or complex analyses. By leveraging the power of multiple cores or threads, parallel processing allows for faster execution and more efficient resource utilization.

It’s worth noting that not all GIS tasks can be parallelized effectively. Some operations inherently rely on sequential processing or have dependencies that limit the extent of parallelization. Additionally, the degree of speedup achieved through parallel processing depends on factors such as the number of cores/threads, task granularity, and the efficiency of the parallelisation algorithm.

Some examples of GIS tasks that can benefit from parallel processing

  1. Spatial Analysis: Tasks such as overlay analysis, proximity analysis, and raster operations can be parallelized. For example, if you are performing a buffer analysis on a large dataset with multiple buffer zones, each buffer zone can be processed independently in parallel.
  2. Geoprocessing: GIS projects often involve extensive geoprocessing operations, such as feature extraction, data conversion, or terrain analysis. These tasks can be divided into smaller units and processed in parallel to expedite the overall processing time.
  3. Image Processing: GIS often involves working with large satellite imagery or aerial photographs. Image processing tasks like image classification, image enhancement, or image mosaicking can be parallelized to handle the high computational demands efficiently.
  4. Network Analysis: When dealing with network datasets, parallel processing can be beneficial for tasks such as route optimization, service area calculations, or network tracing. Each route or service area can be computed independently in parallel, leading to faster results.
  5. Big Data Analysis: With the increasing availability of big geospatial data, parallel processing becomes crucial. Tasks such as clustering, pattern recognition, or anomaly detection can leverage parallel processing to handle large volumes of data effectively.
  6. Parallel Rendering: Generating visualizations or maps from large datasets can be computationally intensive. Parallel rendering techniques distribute the rendering workload across multiple processors or threads to speed up the visualization generation process.

Free and Open Source Software: Empowering the Geospatial and GIS Industries

Free and open source software (FOSS) refers to software that is released under a license that grants the user the freedom to use, modify, and redistribute the software. FOSS emerged as a response to proprietary software that restricted users’ rights and access to the source code. The establishment of FOSS has had a profound impact on the software industry and has created a community of developers, users, and advocates who support its ideals.

The concept of FOSS originated in the 1980s with the Free Software Foundation (FSF), which was founded by Richard Stallman. The FSF advocated for the creation of software that could be freely shared and modified, and Stallman created the GNU Project, which aimed to create a complete free and open source operating system. The GNU Project produced many of the tools and utilities that are commonly used in FOSS today, such as the GNU Compiler Collection (GCC) and the GNU C Library.

In the 1990s, the rise of the internet and the World Wide Web enabled the spread of FOSS and the development of new FOSS projects. One of the most significant of these projects was the Linux kernel, which was created by Linus Torvalds in 1991. The Linux kernel, combined with GNU tools and utilities, created a free and open source operating system that was capable of running on a wide range of hardware.

The establishment of FOSS has created a community of developers, users, and advocates who support its ideals. FOSS developers contribute code to projects, fix bugs, and help support users. FOSS users can download and use software for free, and they also have the freedom to modify and redistribute the software. FOSS advocates promote the use of FOSS and its ideals of openness, collaboration, and community.

FOSS has had a significant impact on the geospatial and GIS industries. Geospatial data and GIS software are critical components of many industries, including environmental management, urban planning, transportation, and emergency management.

Introduction

Geographic Information Systems (GIS) are powerful computer-based tools that allow users to collect, store, analyze, and manipulate geographic data. The proliferation and advancement of GIS have been instrumental in resolving complex spatial problems across various disciplines (Heywood, Cornelius & Carver, 2011). To cater to the diverse needs of different domains, numerous approaches to GIS software development have been devised. The following sections delve into four prominent approaches: (1) writing code without help from existing GIS software; (2) customizing existing GIS software; (3) creating new functions using GIS macros/scripts; (4) loosely and tightly coupled integration.

Approach 1 – Write Your Own Code Without Help From Existing GIS Software

Developing GIS software from scratch entails a significant amount of time, effort, and technical expertise (Burrough & McDonnell, 1998). However, this approach allows developers to create tailor-made solutions specific to a particular problem or user group, thereby ensuring optimal performance and seamless compatibility with other systems (Longley et al., 2015). Furthermore, designing GIS software from the ground up facilitates the incorporation of novel algorithms, techniques, and data structures that may not be present in pre-existing software (Worboys & Duckham, 2004).

Despite its advantages, writing code without utilizing existing GIS software presents several challenges. First, it requires a deep understanding of geospatial concepts, data formats, and programming languages (Chang, 2016). Second, the development process can be time-consuming and resource-intensive, particularly for small organizations or individual developers. Finally, this approach may result in a lack of standardization and interoperability with other GIS software, potentially limiting its usability across different platforms (Goodchild, 1992).

Approach 2 – Customizing Existing GIS Software

Customizing existing GIS software involves modifying and extending the functionality of commercial or open-source GIS platforms to suit specific requirements (Steiniger & Bocher, 2009). This approach benefits from the extensive features, documentation, and user communities associated with popular GIS platforms, such as ArcGIS, QGIS, and GRASS GIS. Consequently, customization reduces development time and costs compared to building software from scratch.

Examples of customization include developing plugins or extensions that add new tools or capabilities to the core software or creating custom scripts that automate routine tasks (Tomlinson, 2013). Although customization generally offers greater flexibility than using off-the-shelf software, it is inevitably constrained by the underlying architecture and design of the original platform (Heywood et al., 2011).

Approach 3 – Creating New Functions Using GIS Macro/Scripts

This approach enables developers to create new functionalities for existing GIS software by leveraging macros or scripting languages (e.g., Python, R, or JavaScript) (Chang, 2016). Macros/scripts are relatively easy to learn and implement, making them an attractive option for developers with limited programming experience (Longley et al., 2015). In addition, macros/scripts facilitate rapid prototyping and testing of new functions, thereby expediting the development process.

However, relying solely on macros/scripts may restrict access to lower-level system functions and data structures, potentially limiting the performance and sophistication of newly developed tools (Worboys & Duckham, 2004). Furthermore, compatibility issues may arise when attempting to share macros/scripts across different software platforms or versions (Steiniger & Bocher, 2009).

Approach 4 – Loosely and Tightly Coupled Integration

Loose coupling and tight coupling are two distinct methods for integrating GIS functions with other software systems. Loose coupling facilitates modularity and flexibility by connecting separate software components through well-defined interfaces such as web services or APIs (Goodchild, Fu & Rich, 2007), thereby allowing developers to interchange components without affecting overall system function (Chang, 2016). This approach is particularly advantageous for projects necessitating interoperability between multiple systems, as it enables data and functionality exchange via standardized interfaces (Bian, 2012). However, loose coupling may not always yield optimal performance and seamless integration, potentially leading to slower execution times and user interface inconsistencies (Xiao et al., 2008).

Conversely, tight coupling involves embedding GIS functions directly within another software application, creating a close interdependence between the systems (Longley et al., 2015). While this method may result in improved performance and tighter integration, it also introduces complexity and potential maintenance issues, especially when upgrading or modifying individual components (Heywood et al., 2011). Tight coupling is well-suited for projects demanding a customized and highly performant solution where GIS functionality plays a central role in the software’s purpose (Tomlinson, 2013). Nevertheless, the increased complexity and maintenance challenges that come with tight coupling require careful consideration of component interdependencies during system upgrades or modifications (Worboys & Duckham, 2004).

Discussion

The four approaches to GIS software development discussed in this article offer different levels of flexibility, complexity, and customization. Each approach has distinct advantages and disadvantages that must be carefully weighed according to the specific needs and resources of the project at hand.

Approach 1 (writing code without existing GIS software) offers the highest degree of customization but also entails a substantial investment of time, expertise, and resources. This approach may be suitable for projects requiring highly specialized solutions or those seeking to incorporate novel algorithms or techniques not available in existing software.

Approach 2 (customizing existing GIS software) provides a more efficient and cost-effective method for tailoring GIS platforms to specific requirements. This approach benefits from the existing features, documentation, and user communities of popular GIS software. However, it is inherently constrained by the design and architecture of the underlying platform, limiting customization potential compared to Approach 1.

Approach 3 (creating new functions using macros/scripts) offers a rapid and accessible means for extending GIS functionality with limited programming experience required. While this approach is well-suited for prototyping and testing new functions, it may restrict access to lower-level system functions and data structures, thus limiting performance and sophistication.

Approach 4 (loosely and tightly coupled integration) focuses on integrating GIS functions with other software systems. Loose coupling emphasizes modularity and interoperability, making it ideal for projects involving multiple systems. On the other hand, tight coupling provides closer integration and improved performance at the expense of increased complexity and maintenance challenges.

Conclusion

In conclusion, the choice of GIS software development approach largely depends on the objectives, resources, and constraints of the project. Developers must carefully assess the desired level of customization, integration, and performance against the required time, expertise, and resource commitments. As the demand for GIS continues to expand across numerous fields, understanding these various approaches can help ensure the successful development and implementation of innovative GIS software tailored to address the diverse and evolving needs of different domains. Future research in this area would benefit from case studies and comparative analyses of these approaches to further elucidate their relative strengths and weaknesses, as well as exploring emerging trends and techniques in GIS software development.

The Evolution of GIS Software Vendors: From Early Beginnings to Modern Advancements

By Shahabuddin Amerudin

GIS (Geographic Information System) software has come a long way since the first systems were developed in the 1960s. From humble beginnings as experimental research tools, GIS software applications have become essential components of numerous industries, including urban planning, environmental management, and disaster response. In this article, we will take a look at the progress of GIS software vendors from the earliest days of GIS to the present day.

The earliest GIS software systems were developed in the 1960s and 1970s by researchers at universities and government agencies. These systems were experimental and primarily used for research purposes, but they laid the foundation for the development of more sophisticated GIS software applications in the following decades. One notable early system was the Canada Geographic Information System (CGIS), which was developed by the Canadian government in the early 1960s (Foresman, 1998).

The 1970s and 1980s saw the birth of a number of companies that specialised in the production of commercial GIS software. These companies included Environmental Systems Research Institute (ESRI), Intergraph, and AutoDesk.These systems were still rather complicated and expensive, but they were getting easier to operate and more accessible to those who were not specialists in the field. They embarked on the process of creating and distributing GIS software solutions for a variety of business sectors. These companies built software applications that were both more user-friendly and more affordably priced than the systems that came before them, which made GIS available to a larger variety of customers (Longley et al., 2015).

The 1990s saw a significant expansion in the availability and use of GIS software. The introduction of Windows-based operating systems and the development of user-friendly interfaces made GIS software more accessible to a wider range of users. This, in turn, led to an increase in demand for GIS software, particularly in industries such as urban planning, transportation, and environmental management. GIS software vendors began to focus on integrating GIS with other software systems, such as enterprise resource planning (ERP) and customer relationship management (CRM) software. This integration helped to further expand the use of GIS beyond traditional mapping and spatial analysis applications (Batty, 2013). One of the major advancements in GIS software occurred in the 1990s with the introduction of web-based GIS. This allowed users to access GIS data and applications through a web browser, making GIS more accessible to a wider range of users. 

The 2000s saw the emergence of cloud-based GIS software, which allowed users to access GIS applications from anywhere with an Internet connection. This technology has helped to democratize GIS, making it more accessible to smaller organizations and individuals (Goodchild, 2010). This has made GIS more flexible and scalable, and has allowed organizations to more easily share and collaborate on GIS data. This led to an explosion in the availability and diversity of GIS software applications, as well as the emergence of new business models based on software-as-a-service (SaaS) and cloud computing.

In the 2010s, the GIS industry saw significant developments, including the emergence of cloud-based GIS software, which provided users with access to GIS software and data from any location. The use of mobile GIS also increased during this period, enabling GIS professionals to collect and analyze data in the field. GIS software vendors, such as TerraGo and Trimble, developed mobile software solutions for real-time data collection and analysis. Additionally, companies such as Tableau and QGIS improved the visualization of spatial data, allowing users to create sophisticated data visualizations, including maps, charts, and graphs. These advancements made GIS more accessible, affordable, and easy to use for smaller organizations and individuals. (ESRI, 2010; Trimble, 2013; Tableau, 2013).

The 2020s have seen several significant advancements in the GIS industry, including the integration of AI and machine learning into GIS software solutions. GIS software vendors such as ESRI and Google have developed AI and ML tools that allow users to automate tasks and gain new insights into spatial data (Google, 2021).. Additionally, the use of open source GIS software has become increasingly popular, with vendors like QGIS and GeoServer offering solutions that are comparable or even better than proprietary GIS software (GeoServer, 2021). With the increasing amount of spatial data being collected, GIS software vendors are also placing greater emphasis on data privacy and security. Trimble and ESRI are among the companies that have developed software solutions that provide users with greater control over their data and help them comply with data privacy regulations (Trimble, 2021).. These advancements are paving the way for new possibilities in the GIS industry and are helping to make spatial data analysis more accessible and secure than ever before.

As the use of GIS continues to expand across industries and sectors, GIS software vendors are also facing new challenges. One of the biggest challenges is ensuring the security of GIS data, particularly as more organizations move to cloud-based GIS solutions. GIS software vendors must implement robust security measures, such as encryption and access controls, to protect GIS data from unauthorized access and cyberattacks.

Overall, the progress of GIS software vendors over the past several decades has been impressive, and the future looks bright for the continued development and application of GIS technology. As GIS software becomes increasingly accessible and user-friendly, it is likely that we will see even more widespread adoption of GIS technology across industries and fields, leading to new insights and innovations that can help us better understand and manage our world.
