Chapters 1 and 2 cover Web GIS basics and real-world applications. Its various benefits are shown below. Web GIS, a mix of web technologies and geographic information systems, can reach people worldwide, is economical, works on numerous platforms, is easy to use, and is easy to manage. It transforms spatial data analysis and is employed in government, industry, science, and daily life. Users, groups, content, and information are introduced in Chapter 1 of Web GIS. It emphasizes Web GIS’s ease of data sharing and analysis across platforms. The five core online GIS materials are data, layers, tools, online maps and scenes, and apps. These components enable dynamic and interactive spatial apps. Chapter 2 of the Esri Geospatial Cloud covers hosted layer types. These include hosted features, tile, scene, and picture layers. Users may simply construct high-quality maps and graphically evaluate the data using smart mapping techniques. A powerful expression language in ArcGIS Arcade enables you to customize layer and pop-up appearances, improving the user experience and data interpretation. Let’s imagine a real-world application for these principles. Imagine interning in Columbus on a highway, road, or bridge project. Web GIS lets you create an app to manage and visualize project data. This app could display material storage yards, field offices, temporary infrastructure, and material information. You may also track oil spills, accidents, and pipe installation and removal for better management and safety. Web GIS mapping types like dot density and vector fields reveal spatial patterns and trends. This aids decision-making. The infrastructure project was completed successfully because this tool simplifies project management and lets everyone involved communicate and collaborate. The basic information from Chapter 1 and the relevant strategies from Chapter 2 provide people and groups with the tools to utilize Web GIS effectively. This affects how it comprehends, handles, and uses geographical data in numerous scenarios.
