ArcGIS Online
ArcGIS Online is a cloud-based geographic information system (GIS) platform developed by Esri that allows users to create, share, and analyze maps and spatial data. It provides tools for mapping, data visualization, spatial analysis, and collaboration without requiring on-premises infrastructure. Users can access it through web browsers and mobile apps, making it a versatile solution for organizations of all sizes.
Developers should learn ArcGIS Online when building applications that require mapping, geospatial data visualization, or location-based services, such as environmental monitoring, urban planning, logistics, or real estate platforms. It's particularly useful for integrating GIS capabilities into web and mobile apps without deep GIS expertise, as it offers APIs, SDKs, and pre-built tools for embedding maps and spatial analysis. Use cases include creating interactive dashboards, performing spatial queries, and managing field data collection.
