- ArcGIS Mobile —ArcGIS Mobile is a task-driven mobile application for Windows Mobile devices that uses a web services architecture to synchronize information between the field and office. Field maps and field workflows are configurable using a web application called Manager that ships with the ArcGIS Server product. ArcGIS Mobile includes tasks for field map viewing, field inspection and field data collection. ArcGIS Mobile also includes an SDK for building very focused applications that run on Windows Mobile devices, Windows CE .NET devices, and Windows Tablet PC devices.
- ArcPad—A mobile GIS application for taking GIS to the field. ArcPad is map-centric and focuses on field tasks that require relatively simple geographic tools. These tasks are typically performed on handheld computers (running Microsoft Windows CE or Pocket PC).
- ArcGIS Desktop and ArcGIS Engine—These products provide tools for high-end mobile GIS with sophisticated mapping, display, and editing tools. These solutions focus on field tasks that require more sophisticated geographic tools, typically running on high-end Tablet PCs. Often, the map displays used in the field on Tablet PCs must contain detailed information in high-resolution.
ESRI 提供三種開發Mobile GIS的方法，分別為ArcGIS Mobile ADF、ArcPad、ArcGIS Desktop或ArcGIS Engine。
目前先把重心擺在ArcGIS Mobile ADF上，好好研究。
