project took 4-5 years to complete. Owing to the reasons |
mapping projects are very important for Saudi Arabia. The
project presented in this article is very significant for high
precision mapping, facility management and automating
mapping. In the office work we got some problems by
converting the Microstation Geographics *.dgn file into
Geomedia. The problem was with the Mslink numbers which
were created by Microstation Geographics as a primary index
field for graphic features and database. We tranfered the file to KEY W
Arc View shape format to solve this problem and then we add
the shape files as a new feature class in Geomedia. As a result ABSTR.
for RTK survey in Riyadh, our crews had very efficiency Saddled
product between 7.00 AM and 12.00 PM in the work performed PAN
variables
in Riyadh according the position of the satellites. After 12.00 use GIS
PM even some reduce in the quantity of the satellites detected vm
