Fibre Cable
Greg's Cable Map is an attempt to consolidate all the available information about the undersea communications infrastructure. The initial data was harvested from Wikipedia, and further information was gathered by simply googling and transcribing as much data as possible into a useful format, namely a rich geocoded format. I hope you find the resource useful and any constructive criticism is welcome.A mate of mine did an article on it on his South African Tech site, Check it out if you want more background info.

Measurements recorded
Unit harmonisation applied to this dataset
Every number in Atlas is stored in one canonical unit; the original value and unit are always kept
| Source field | Measure | Source unit | Atlas unit | Factor | Treatment |
|---|---|---|---|---|---|
| Shape_Length | area/length | unknown (often degrees) | — | — | excluded unit not stated; geodesic area/length computed from geometry instead |
| geometry | area / length | EPSG:4326 degrees | ha / m | — | geodesic area (ha), perimeter (m) and length (km) computed on the WGS 84 ellipsoid with PostGIS |
Attributes stored per feature
How many features carry each attribute (first 20,000)
| Attribute | Features |
