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.

Approaches in Developing GIS Software

By Shahabuddin Amerudin

Abstract

Geographic Information Systems (GIS) have become indispensable tools to a wide array of fields, including environmental management, urban planning, and public health. As the demand for GIS continues to grow, so does the need for innovative GIS software. This article examines four distinct approaches to GIS software development, ranging from writing code without help from existing GIS software to integrating GIS functions through loose and tight coupling methods.

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.

Mapping Flood Risk Around the World: Which Countries and Populations are Most Vulnerable?

By Shahabuddin Amerudin

The above figure shows the risk of flooding mapped around the world (Conte, 2022). The study uses data from Nature to map flood risks around the world and identifies countries and populations vulnerable to the risk of flooding (Rentschler et. al, 2022). The methodology includes both inland and coastal flooding risks. The Netherlands and Bangladesh have more than half of their population at risk due to flooding, followed by Vietnam, Egypt, and Myanmar. The Southeast Asia region makes up more than two-thirds of the global population exposed to flooding risk. China and India account for the highest absolute number of people at risk of rising water levels. Pakistan is particularly vulnerable to floods, with 31% of its population (72 million people) at risk of flooding. Flooding is already affecting countries like Pakistan, and the rising human toll is a major concern. Floods also bring with them massive economic costs, and the forecasted water risk caused by floods, droughts, and storms could eat up $5.6 trillion of global GDP by 2050.

Rentschler et. al (2022) reveals that coastal and riverine countries with flatlands are the most vulnerable to the risk of flooding. It highlights the need for these countries to prepare and develop effective flood management plans to mitigate the impact of flooding. Countries like Bangladesh have already been developing innovative solutions like floating hospitals, schools, and homes, to cope with the increased risk of flooding. Such solutions could be adopted by other countries to deal with the risks associated with flooding.

Conte (2022) emphasizes the need for urgent action to address the increasing risk of flooding. The rising human toll and the massive economic costs caused by flooding highlight the urgency of developing effective flood management plans. Governments and policymakers need to prioritize climate action and allocate sufficient resources to manage the risks associated with flooding. Such measures would require international cooperation, particularly in developing countries that lack the necessary resources and technology to deal with the impact of flooding.

In conclusion, Conte (2022) presents an analysis of the risk of flooding mapped around the world. It highlights the countries and populations most vulnerable to flooding, the impact of flooding on human life and the economy, and the urgent need for action to address the issue. The study calls for innovative solutions, international cooperation, and sufficient resources to develop effective flood management plans to mitigate the risks associated with flooding.
