Hi,

i have to create a map for university (I'm not a professional) that will be published, so the data has to be freely available with no publishing restrictions. i guess the license i need for this is "public domain".

while SRTM data is public domain and i can use this data, i got some problems with the vector data of mainly the rivers.

So vmap 0 is in public domain:

http://gis-lab.info/qa/vmap0-eng.html (in shapefiles)

what about vmap 1 ? is the data published here in shp format: http://gis-lab.info/qa/vmap1-eng.html also in the public domain? does anybody know this?

i found another ressource of free geodata on the diva GIS homepage: http://www.diva-gis.org/gdata

most of the data belongs to the digital chart of the world project. do you know if the data also is public domain, so that I can publish it on a map without indicating the source?

so in fact, these are the two big ressources i found until now. do you know other geodata ressources like that, which may be published as a map without indicating the ressource?

another problem: even the data of digital chart of the world are quite detailed. if I need data only on a scale of 1:3.000.000 or even higher, some data (as rivers of rhine, danube, rhône) are just too much detailed. I know that the generic mapping tools also got data in those scales, but i can't handle this programm. of course I can create a new shapefile on basis of the more detailed vmap0 data, but isn't there a possibility to get those geodata out of generic mapping tools or isn't it published anywhere online for download? unfortunately the vmap0 and 1 geodata doesn't have a suitable hierarchy for that and those big rivers aren't "idealized" for serving those big scales.
to summarzie: do you know any freely available (best is public domain data) for scales of >1:3.000.000 to 10:000.000 ? those must have some "idealized" data of e.g. big rivers.

sry for the broken english. i'd be really happy for some tipps.

greetings dav

Why not? GMT is a bit intimidating at first, but it is very powerful. You should give it a try.

I can send you the river data from GMT in ASCII format if you wish.

hi,

thank you. unfortunately the private message function isn't working for me...i'd be really thankful if you could send me those data. in fact I need the big rivers around the ural mountains and the caspian sea. (ural, tobol, yrtisch, karna, wolga, etc..) If GMT has the data with those rivers in this area, it would be great if you can send them to me. the data of GMT is public domain, no? (i simply can make a shapefile out of the ASCII data by: ASCII to CSV in excel and CSV to .shp in a GIS like gvSIG or Mapwindow, no? unfortunately for this moment i can't use arcmap. )

thank you, dav

Could you try again? We've got that switched off for "new members" (spammers were abusing it), but I've just validated you so it should work now.

As a general note to anybody looking for geodata, we do have a resources section (up there, 2nd blue button from the right) that includes links to various datasets. If you have any links you want add to that, please fill out the form and then ping one of us moderators so we can approve it.
