I’m trying to define a project entering the free data of the NGA topo maps of Central America (only Nicaragua, Honduras, Guatemala & El Salvador) into OSM. Highest priority have water layers and mountains, less important would be names of settlements.

The NGA maps were all published between 1965 and 2003, most of them in the sixties and seventies. A lot of settlements are inaccurate, because they became bigger or even changed their names. Peaks and water entities are more reliable.

My idea is to get some funding and work with local universities and student to enter the data. At the moment, I’m running tests to figure out how much work in hours needs to be done. After serveral checks, I think, we have to calculate about 2 days (15 hours) per 1:50k map for mountains and water bodies.

If anybody would like to be included in this project, contact me at miluethi@rucksackradar.net.

Cheers

I’m entering all Municipalities going from North-West to South-East. This requires often adjustments to the existing state boundaries, many of them are completely wrong.

The new borders were published by Instituto Nacional de Información de Desarrollo (www.inide.gob.ni) 2013. We have a written permit to use publish them by the URACCAN University.

Today’s Goal:

Preparation work for the entering the border of the municipality of Paiwas (RAAS)

I did:

• all rivers which are the borderline between the municipality of Paiwas and neighboring municipalities
• all peaks on the border of the municipality of Paiwas
