ArcGIS Online is a cloud-based Geographic Information System (GIS) platform that allows users to create, analyze, and share interactive maps and spatial data. It provides access to a rich library of basemaps and spatial datasets, and tools for performing spatial analysis (like buffering, geocoding, routing). Users can upload their own data, style it, and build web maps and applications that can be shared within an organization or publicly. As part of Esri's ArcGIS ecosystem, ArcGIS Online integrates with desktop GIS tools and supports collaboration, making geospatial analysis and map publishing accessible via the web without managing server infrastructure.
