Step 1: Concept
GIS software platforms are designed differently based on where and how the user needs to operate them.
Step 2: Meaning
Professionals actively collecting or analyzing data outdoors (in the field) require portable hardware and specialized software capable of real-time spatial processing.
Step 3: Analysis
• Desktop GIS is confined to office computers for heavy processing.
• Web GIS allows browser-based map viewing and sharing over the internet.
• Mobile GIS brings core spatial functionalities (like on-site measuring, buffering, and live data collection) directly to portable devices like smartphones and rugged tablets used during active field surveys.
Step 4: Conclusion
The deployment of GIS used during active field surveying is Mobile GIS.
Final Answer: Mobile
