Overview

GGV indicates 3D map with DEM published by USGS and other satellite image.
3D image enables you to see ups and downs which have never recognized on a plan.
It displays 3D maps instantly with changing view points, target points and sources of light.
Our fantastic "Flight simulator mode" enables you to fly over the 3D map by mouse.
(You don't need special hardware or driver software to calculate coordinates and create polygons.)
