I think you need to work backwards from what is your intended use. 
Web, paper print?

So what size are the photographs from Google earth?

What I have done is simply scanned a road map/atlas at a fairly high 
resolution, added layers of 
routes and comments then resized to suit.

Resizing up doesn't always work real well.

Inkscape is good for making route profiles, you can stretch in both directions 
to give make the 
route look easy or hard :-)

You can try the the Wacom tablets.
They are well supported on most platforms and work nicely in GIMP.

The cheaper models like the Graphire won't break the bank (normally around the  
$100 mark) and will definitely  work a lot better than the typical computer 
mouse.

Even my old Graphire 1 has 256 levels of pressure sensitivity which is an 
extremely useful feature. i.e. The harder you press the more ink comes out 
of the selected tool. Try do that with a standard mouse ...

For that I use both. In the first Gimp is better make specific 
selections on the map (rivers...) and transform it in path. For the 
roads I prefer make paths manually over the map, stroke these paths on 
specific layers with correct line width and convert these strokes in 
paths. Remove initial paths drawn and you can export all paths in svg 
file smaller and more easy to resize than xcf file. After it is more 
easy to modify it this inkscape.


But perhaps there is best ways to make this work.

[Gimp-user] is it possible to create a fade transition .gif iwth GIMP

2007-04-06 Thread Bob Meetin
Subject says it all, mostly.  I'd like to know if it is possible to 
create a fade-in, fade-out transitional effect with a single .gif image 
using GIMP?  Preferaby where the image one fade out intersects with the 
image two fade in?  -Bob

You can save layered images to gif as animated gif. By doing so, each  
layer is used as one frame of the animation.
You might wand to have a look to the manual at page http:// 
docs.gimp.org/en/gimp-dialogs-structure.html and http://docs.gimp.org/ 
en/gimp-images-out.html#id2557519

Since you're starting with a bitmapped image anyway (a satellite
photo), GIMP is fine. Any problems you get from rescaling the trails
will also be problems when rescaling the image, so you wouldn't
get any advantage from using Inkscape.

I've used GIMP to make map overlays: for instance, a topographic map
layer, a trail map (converted from the park's online PDF), and a
geologic map layer (converted from a USGS PDF). Then I can adjust
the transparencies and colors of all the layers depending on which
combination I want to print out for a specific project. It's a lot
of work getting everything scaled just right (it would be so much
easier if this info was all available in open GIS formats that
worked in free mapping software ... maybe some day!) but the results
can be very useful.
