AfTerFibre again

[Song, Stephen]

Hi all,

After a bit of a hiatus, I am having another go at mapping terrestrial fibre in Africa.  The last attempt failed to catch fire so I am trying a new approach this time.

1/  I am experimenting with a cloud-based geo-mapping platform called CartoDB.  CartoDB is a popular cloud GIS platform that simplifies a lot of complex mapping chores.  The result is better looking maps with more detail.

2/  I am going to focus on a few countries to start with rather than target the whole continent at first. 

3/  I am going to try to capture PoPs as well as routes as well as details about the underlying technology.

Here are some preliminary views of fibre in Ghana and Nigeria.

For each fibre network, the map data will be downloadable in the GIS editing format of your choice for those would like to correct any inaccuracies or upload new information.

Comments, suggestions, welcome.

Regards... Steve Song

HI Steve,

I am really interested to know how this is going. I am also having a plan to map the fiber with individual strands info along with duct, cable id etc. Is this possible with cartodb?

Thanks for your post

Hi Hari,

Thanks for your interest!  It's going well.  You can see its progress at:

https://afterfibre.cartodb.com/tables/af_fibrephase/map

If you zoom into Johannesburg or Cape Town, you can see where very detailed fibre information has been imported from Dark Fibre Africa. 

Currently the plan is to have fields that capture the following technical information

- install_type:  what kind of fibre deployment e.g. underground, OGW, etc

- fibre_cores:  number of fibre cores

- fibre_type:  what kind of optical fiber is in the installed cable (based on ITU fibre types e.g. G.652.D, G.653, G.655, etc)

- lit_technology: optical technology e.g. DWDM

You certainly could create a table that maps right down to each individual core but that is beyond the scope of AfTerFibre at the moment.  Currently, each record in the main table describes what I refer to as a "fibre phase".  Most terrestrial fibre networks are built in phases and capturing that information can help to show national fibre network growth.  

I also plan to link the fibre table to an organisation table which will allow us to capture more detailed information on:

- ownership

- operation

- parent company ownership

- who built the network

- who financed the network

Currently still somewhat under-resourced in its development though.  Sponsors welcome.  :)

Cheers... Steve
