GPS technology considers the essential tool for establishing geodetic networks.
Static method of GPS is used often in observing geodetic network points. Establishing
geodetic networks using GPS requires accuracy, consistency and economency.
This p
aper discusses influence of observation mode and number of GPS receivers in
accuracy of calculating of coordinates of points. Coordinates of network points are
clculated using tow and three GPS receivers and with diferent methods like radial, traverse,
network.
Comparison between coordinates for network points obtained by several cases is
performed. The differences between coordinates indicate accuracy of network method in
calculating coordinates when three or more receivers are avlible. When tow receivers are
avilable the radial method is the best in accuracy and consistency.
Marine sources are of the important sources of coastal States, where a significant
portion of its economy is tied to people who earn their living from these sources [4]. After
the discovery of mineral and hydrocarbons ores at the seabed, and also b
ecause of the
disputes between States on fishing regions, it became necessary for some States to
reconsider their idea regarding maritime boundaries and open the disputed files with
neighboring States even it is over a small area, to demand re-delimitation of their maritime
boundaries, even if it required the intervention of the International Court of Justice. In this
research a way is purposed to draw he coast line by using Google Earth detailed photos for
the derivation of Lattakia coast baseline and studying its various special issues. The search
has found good results in identifying those lines allowing full generalization on the Syrian
coast, and also allowing for subsequent research linked to those lines.
