telecom network spanning multiple zones

Question

Hi,

Disclaimer:

am facing a problem with telecom network in a project, this issue actually can apply to any other network, not necessary telcos, am asking in this forum since am working with a telecom network.

The problem:

am working in UAE and the country falls into UTM zone39N and UTM zone40N, the telecom network spreads covering the whole country and this means the network is covering both zones:

how can i represent the network accurately while it falls into 2 different projected areas?

Applications:

am using Ericsson Network Engineer to model telecom network, which runs ontop of ESRI ArcGIS Desktop, this application creates its own data set, to record the telecom network elements, and this data set needs to be projected, and i cant create 2 data sets, the application only accepts one data set. plus there is the geometric network issue. if successfully created 2 data sets:

is there a way to create a common geometric network between 2 different data sets?

Thanks for help.

Hi,

You could define a custom coordinate system, perhaps transverse Mercator, with the central meridian set around 54E or 55E or a Lambert conformal conic. Another possibility is to use one of the UTM zones. It looks like more of the country is in 39N, but is there's more development in 40N. If you decide to go with an existing projected coordinate system, you could choose 40N. You'll have several degrees of data 'outside' the zone, but transverse Mercator can project/unproject cleanly.

Hi Melita,

thank you for your reply, greatly appreciated.

we are exploring the solution you have provided, however we were hoping to find an answer on the application level regarding Ericsson Network Engineer, nonetheless appreciate your contribution.
