| description | Technology for photogrammetric data processing, especially aerial
photograph has evolved towards digital era. One of the products is DEM (Digital
Elevation Model). DEM from aerial photo can be produced using computers and
supporting software. It can be done by automatic stereoplotting or interactive
stereoplotting. The purpose of this research is to know the DEM accuraccy obtained
from interactive stereoplotting of medium format aerial photo through Relative
Orientation stage.
The location of research is Lembah Universitas Gadjah Mada area with
varying tophography. Data needed to conduct this study were medium format aerial
photo, DEM data resulted from LiDAR classification and data orthophoto. The
stages in data processing are all orientation process (IO, RO and AO) for producing
EOP value. Analysis of DEM accuracy was calculated by comparing the Z
coordinate of sample points of DEM data resulted from interactive stereoplotting
with DEM resulted from LiDAR data clasification. Than interactive stereoplotting
process was executed to produce a DEM data. The accuracy level of DEM resulted
from interactive stereoplotting can be determined by calculating the standard
deviation of the sample data in the form of a sample points. The data samples were
selected such that the chosen sample could represent the overall data population.
The number of samples used in this research were 203 sample points. From
the calculation, it was obtained that in the average height difference is 0.38 meter
and the standard deviation is 0.43 meter. The higest height difference is 2.68 meters
while the smallest height difference is 0 meters. Of the 203 sample data, there are
144 sample data have smaller height difference than the value of maximum accuracy.
DEM accuracy was previsiously determined based on operator ability to do
interactive stereoplotting on aerial photo. |
