Which of the following statements best describes the difference between GPS and GIS?
GPS provides real-time spatial data, while GIS focuses on spatial data analysis.
GPS is used for collecting spatial data, while GIS is used for navigation purposes
GPS uses satellites to determine location, while GIS integrates and analyzes spatial data.
GPS and GIS are interchangeable terms for the same technology
What are some challenges associated with the integration of GPS, GIS, and remote sensing data?
Data accuracy, interoperability, and processing speed
GPS signal interference, GIS software compatibility, and sensor calibration
Satellite coverage, GIS database management, and remote sensing resolution
