Abstract
Geographic Information System (GIS) software is an essential tool that enables the processing, analysis, and visualization of geographic data. This article aims to provide a thorough review of various types of GIS software systems, which include desktop GIS, server GIS, developer GIS, mobile GIS, raster-based GIS software system, computer-aided design (CAD)-based GIS, GIS middleware, and open-source and free software.
Introduction
The ubiquity of spatial data has propelled the importance of Geographic Information Systems (GIS) in recent years. GIS allows users to capture, store, analyze, manage, and present spatial or geographic information across various domains, such as urban planning, natural resource management, and disaster response (Longley, Goodchild, Maguire, & Rhind, 2015). There are several types of GIS software systems, each with unique characteristics and applications. This article provides a comprehensive overview of these different types, highlighting their features and relevance in modern GIS practice.
Desktop GIS
Desktop GIS refers to standalone software that runs on personal computers and is primarily used for data creation, editing, and visualization purposes (Heywood, Cornelius, & Carver, 2011). Some popular desktop GIS software includes ArcGIS, QGIS, and MapInfo Professional. Desktop GIS software generally offers a user-friendly interface, allowing users to perform spatial analysis, query data, create maps, and generate reports. These tools can handle small to medium-sized datasets and are ideal for individual researchers or small organizations (Longley et al., 2015).
Server GIS
Server GIS software allows multiple users to access, manipulate, and share spatial data in real-time through web services or cloud-based platforms (Peng & Tsou, 2003). This type of software is designed for organizations that need to manage large volumes of data and require collaboration between multiple users simultaneously. Examples of server GIS include ArcGIS Server, GeoServer, and MapServer. By centralizing data storage and processing, server GIS reduces redundancy and ensures that users have access to the most up-to-date information (Heywood et al., 2011).
Developer GIS
Developer GIS comprises libraries, tools, and Application Programming Interfaces (APIs) that enable software developers to create custom GIS applications for diverse user groups (Longley et al., 2015). These tools can integrate GIS functionality into existing applications or develop entirely new ones tailored to specific needs. Popular developer GIS software includes ESRI’s ArcObjects, Google Maps API, and Leaflet.js. By leveraging these tools, developers can create specialized solutions for unique spatial problems across various industries.
Mobile GIS
Mobile GIS refers to GIS software designed for mobile devices such as smartphones and tablets (Tsou, 2004). This category of GIS software allows users to collect, edit, and analyze geographic data in real-time while in the field. Examples of mobile GIS applications include ArcGIS Collector, QField, and Locus Map. Mobile GIS software takes advantage of GPS technology to provide location-based services, enabling users to track assets, navigate using digital maps, and conduct field surveys efficiently (Tsou, 2004).
Other Types of GIS Software Systems
Raster-Based GIS Software System: Raster-based GIS focuses on representing continuous geographic features through grid cells or pixels, with each cell assigned a particular value (Foody, 2002). This type of GIS software is particularly useful for analyzing and modeling environmental data, such as elevation, land use, and vegetation. Examples include ERDAS IMAGINE, IDRISI, and GRASS GIS.
Computer-Aided Design (CAD) – Based GIS: CAD-based GIS integrates GIS functionality with traditional CAD systems, allowing users to create and manipulate spatial data in a familiar design environment (Karimi & Akinci, 1997). Examples of CAD-based GIS software include AutoCAD Map 3D, Bentley Map, and MicroStation GeoGraphics.
GIS Middleware (Middle Tier): GIS middleware serves as an intermediary between GIS applications and databases, facilitating communication and data exchange between different systems (Plewe, 1997). This type of software includes Esri’s ArcSDE, Oracle Spatial, and PostGIS.
Open-Source and Free Software: Open-source GIS software is developed by communities of developers who collaborate to create free, publicly available tools (Steiniger & Bocher, 2009). These solutions offer an affordable alternative to proprietary software, with popular examples including QGIS, GRASS GIS, and gvSIG.
Discussion
The diverse array of GIS software systems reflects the growing demand for sophisticated spatial analysis tools across various sectors. Each type of GIS software serves specific purposes, catering to the unique requirements of different user groups. Desktop GIS remains a popular choice for individual researchers and small organizations due to its ease of use and relatively low cost. In contrast, server GIS offers robust data management capabilities that support large-scale collaborative efforts, making it an ideal choice for organizations handling vast amounts of spatial data.
Meanwhile, developer GIS empowers software developers to build custom applications tailored to specific industry needs, fostering innovation in the field of GIS. Mobile GIS enhances fieldwork efficiency by enabling real-time data collection and analysis on-site, streamlining workflows and improving decision-making processes. Specialized GIS software systems, such as raster-based GIS and CAD-based GIS, address particular spatial problem domains by offering specialized tools and techniques tailored to those contexts.
Open-source and free software options provide accessible alternatives to commercial GIS solutions, encouraging the democratization of spatial data analysis and promoting knowledge sharing within the GIS community. The availability of various types of GIS software ensures that users can select the most appropriate tools for their specific needs, maximizing the potential benefits of incorporating GIS into their workflows.
Conclusion
In conclusion, the landscape of GIS software systems is vast and varied, with each type catering to distinct user needs and requirements. Understanding the differences between these various systems is crucial for selecting the most suitable tools for a given context. The ongoing development and evolution of GIS software will undoubtedly continue to shape the way we approach spatial data analysis and visualization, empowering users to make informed decisions and derive valuable insights from geographic information.
