Hi!

We have a couple of maps of the coast of Guinea to make and we are looking for an alternative to VMap0.

1:1,000,000 is too small. We are looking for a greater scale (1:250,000... 1:100,000?) but I can't find anything.

For now, we are digitizing almost anything from aerial photography and satellite imagery but it takes to long :(

Any ideas?

Thanks a million times!

VMAP1 seems to have 2 tiles that cover Guinea: 138 and 159, but some small parts are not covered by them:

Have you looked into that? Perhaps it helps a bit.

We've looked at it in the past, but the georeference is off by a good 500m. It's a good start, but... ;) I should have mentioned it.

Thanks! :)

If you are digitizing anyway, the Joint Operations Graphic (JOG) 1:250000 maps are useful.
Buying vector data for them is expensive: over $500 a sheet, but the paper is about $24 each.

That could be good! :)

I'll look into it. Thanks!

You could also check out World Vector Shoreline (WVS). It is at about 1:250k as well.
