Analisa Perbandingan Akurasi Dan Efisiensi Pengambilan Titik Elevasi Muka Tanah Menggunakan Google Earth dan GPS (Studi Kasus Jalan Citandui Sta 3+ 00-4 + 250)

Abstract

In this modern age the elevation point can be made easily, for example taking elevation points can use GPS
(Global Positioning System) or can also use google earth applications available on the internet. In civil
engineering the ground elavation data must be accurate and detailed data. for that whether the above two tool
can be used for accurate and detailed ground elevation point capture.
This study aims to determine the accuracy and efficiency of land elevation point taking with google earth and
GPS, by comparing the elevation results between the to devices againts theodolite measurement results (T.0)
and how the elevation is derived. Beginning with measurement using GPS, google earth done in Citandui street
Urban Village Muara Dua District Kampung Melayu Kota Bengkulu and compare the results of both tools to the
results of theodilite measurement (T.O) the results are closer then it is considered more accurate.
From the comparison, it can be concfuded: (I) that the measurement using google carth application is more
accurate with the average accuracy value of the whole point of the station is 84.82% while the GPS with the
percentage of accuracy is 83.41% 2) based on google earth time more efficient than GPS measuring
istrument with efficient percentage value of 74,8%. Based on google carth cost more efficient 89.1% 3) How
to get elevation data using google earth and GPS is quite easy. Using google earth, done in PC or laptop using
poogle earth application by entering coordinaes of location which have been taken using GPS measuring
instrument, using GP? only need GPS measuring instrument and done location direct research by marking
stations (STA) points.
