Charlestown Nevis Road Network 2019

VerticalGeo spent time this past summer creating road networks for most of the islands in the Caribbean. The screenshots below came from our St Kitts and Nevis Road Network Update Map.  You can view our work there on the simple webmap we have posted online. Every year the islands in the Caribbean get slammed with hurricanes and need humanitarian aid to help overcome the disaster. The people of the Caribbean are very resourceful and resilient, and we decided that we could help them by providing updated road network maps. We started with satellite imagery and began with Open Street Map files of the entire Caribbean. We then took these Open Street Map files and used them to show us where the existing road networks were at. When we came across Open Street Map files that weren't accurate we updated them. When we came across areas where we saw road networks on the satellite imagery, but no roads documented in Open Street Map, we added the roads. When we came across roads documented in Open Street Map that we did not find on satellite imagery we deleted them from our Open Street Map files. In the screenshot below the purple roads are the road network we created for the country of Nevis. Here is a close up of the road network of the town of Charlestown in Nevis. We have completed road network mapping for the following countries:

  • Anguilla

  • Antigua

  • Barbados

  • Barbuda

  • Bolivia

  • British Virgin Islands

  • Cayman Islands

  • Colombia

  • Cuba

  • Dominica

  • Ecuador

  • French Guiana

  • Grenada

  • Guyana

  • Malawi

  • Mozambique

  • Paraguay

  • Saint Barthelemy

  • Saint Martin

  • St Kitts and Nevis

  • St Lucia

  • St Vincent and the Grenadines

  • Trinidad and Tobago

  • US Virgin Islands

We see this as an opportunity to help out the international disaster relief organizations that need data like this to help plan relief efforts around the world.
