Google Earth
Definition
Google Earth is a globe‑based visualization platform that streams multi‑resolution imagery, terrain, and 3D buildings, enabling intuitive exploration of places and time. Users can draw annotations, import KML/GeoJSON, and capture tours. While not a full GIS, it excels at storytelling, outreach, and quick visual checks against high‑quality basemaps.
Application
Educators build place‑based lessons, NGOs showcase conservation projects, journalists illustrate investigations, and planners conduct informal site reviews. The time slider and historical imagery help show change to non‑technical audiences.
FAQ
When should I use Earth versus a GIS desktop?
Use Earth for visualization, narrative, and quick context; use GIS for heavy analysis, data engineering, and precise cartography.
How do I share work from Earth?
Package placemarks and overlays as KML/KMZ, or capture guided tours. Host large overlays as network links so updates stream to viewers.
Is Earth imagery authoritative?
It’s a composite from many providers with varying dates and resolutions. Treat it as context; verify details with official data when accuracy is critical.
Can Earth support fieldwork?
Yes—pre‑plan with placemarks, then collect GPS in the field and import tracks later for QA and storytelling.
