KETEPATAN KOORDINAT BUJUR LINTANG DAN UTM PADA GOOGLE-EARTH SKALA 1 : 1000

Abstract

ABSTRACT
This paper intends to test and find out the accuracy or the deviation information
latitude longitude coordinates (λ, φ) or UTM which is informed on the Google-Earth
image. The research is started by conducting registry longitude-latitude coordinates
and UTM at some points in the Google-Earth, then it is overlaid with visual map
coordinates of the earth scale 1: 25 000 Bakosurtanal publish. Both coordinates are
plotted in the ArcView program in the form of theme-point. Subsequently both these
themes in overlay can be seen visually for deviations from these coordinates and
distance can be measured as well as its deviation from the second point with a
magnification of up to show the level of detail scale 1: 1000. Conclusions can be
drawn that the longitude-latitude coordinates or UTM on Google-Earth can not be used
for technical maps in large scale, but it was enough for making the planning maps in
scale 1: 25.000.
