I am looking for a data source for creating shaded relief for the Rio area.
My final scale is around 1:300,000.
Any pointers?
Thanks..

Interests:I am a Cartographer with varied experience. I work primarily as a freelancer. In my freelancing career I have worked with Maps.com, Designmaps.com, 3dmaps and various other map making and cartography sites.
I have varied software experience, however I use almost all the Cartography and quite a few GIS software, Illustrator, Freehand, Adobe Photoshop and Mapinfo to be precise. I have also worked on Microstation and other Intergraph software including Stereo Photogrammetry on ZI Photo Suites. The other software that I utilize for various other tasks specially 3D realism are Global Mapper and Maprenderer 3D.
Global mapper is a versatile software for various conversion and I found Maprenderer 3D for producing stunning 3D images from height data.
I am available for freelance work, right from mundane line digitisation to Illustrator / Freehand Cartography. Just send me a mail at promapper@gmail.com -

You can easily use SRTM data, with a resolution of 3 sec, it translates to about 90m resolution for the Rio latitude and at 1:300,000 scale a point represents around 75m. If you want a better resolution data then try ASTER DEM at 1 sec resolution but you will require to clean this data.
Both the data sets are available for free download.
