"Is
anyone out there using Global Mapper to process GIS data before sending
it into Illustrator for final map design? I've been trying to do this
but have had little success so far and I'm becoming quite discouraged.
Global Mapper does not export in .ai format so I've tried to get my
data into Illustrator by exporting dxf files for the vectors and
GeoTiff files for the rasters. I have TIGER data superimposed over a
DTM to which I have applied hypsometric tinting and hill shading. I
would like to include an aerial photo on some projects but not all.

When
I use Global Mapper's vector export function, I get a dxf that imports
into Illustrator with feature classes on separate layers and editable
tedxt labels. This is fine except that it comes into Illustrator
absolutely HUGE, way bigger than the art board. At this point I should
probably mention that I am fairly new to Illustrator and haven't worked
with it too much yet, so I might be doing something wrong on the
import. I should also mention that I do not have MAPublisher and that I
am trying to get by on these first few projects without it. It's way
too expensive for someone just getting started in cartography.

I
use Global Mapper's raster export function to get the background image
of my shaded and tinted DEM output as a GeoTiff. When I use the ""place""
command in Illustrator this comes in right in the middle of my dxf, in
a tiny little box that I have to resize to fit the rest of my project.
There is also no way to register the tiff with the dxf, so I have to
eyeball it and I am sure that is not accurate enough for producing
maps. Also, the GeoTiff that comes in is at very low resolution (looks
like 72 dpi to me) even though I specify 300 dpi when sending it out of
Global Mapper. And to add insult to injury, the hill shading comes
through but I lose the hypsometrically tinted colors.

I am at my wit's end with this. Does anybody have any suggestions or am I just using the wrong software for the job?

I don't know much about Global Mapper (hardly anything really...), but I do know a bit about Illustrator...

Your
2 major problems (DXF data coming in huge and the raster graphic coming
in seemingly random) could actually be solved by using MAPublisher. If
you don't have access to it, there's one thing you could probabely do
to make it work out.

Make sure both your DXF and your raster
image have a reference in common. Having some helper objects in the DXF
that correspond to the raster extent would be a big help already. You
can use those to fit them together.

"Liz,
I
have no experience with GM either, but I'll try to help where I can.
Like Hans said, the first thing to do is to make sure your all of your
data shares a common reference in GM. Second, you can always resize
your vector file in Illustrator by selecting the layer, grouping it,
and then resizing it to fit your image and artboard. Just make sure and
hold down the (shift) key while resizing. You can also change the
artboard size at any time in the Document Setup (File menu).

As
far as the raster file goes, have you tried exporting a jpg or png
along with the Tiff and compared the results? Without access to GM at
home, I really don't know what to try here....

I do have Global
Mapper on my computer at work (never used it!). On Monday I can setup a
project similar to yours and export it into Illy and let you know what
I find out.

In the meantime, you may want to check out [url="http://"http://www.cartotalk.com/index.php?showtopic=10"]Manifold GIS[/url] "

I
was in the same boat as you are with Global Mapper. I bought GM 7.0 to
do most of my GIS and bring it all into AI. When it comes to DEM
shading, nothing will beat Global Mapper. It will open and render 2 GB
file in few seconds and making changes in coloration or shading is a
snap. This can take a long, long, long time in any other GIS package.
But that's where the Global Mapper shines and not much else. The only
way to bring geometry into AI is thru DXF. This however is less then
perfect and creates huge file size in AI. I use to bring the terrain
into AI as Bump file and then bring my geo as DXF. I would then scale
the dxf to the background and move it into the right location where the
rivers and roads would line up perfect with the DEM background. This
was somewhat working for me till I had to produce contour lines with
labels. After struggling for few weeks I bought Manifold for $250 and
never looked back. The Manifold has AI export that places everything on
it's own layer and requires very little of editing.

Thank
you all for your help so far. In my attempts to get the data from
Global Mapper to Illustrator I have imported the dxf file first then
placed the raster file and tried to scale it up to match the dxf. I
think this is what is causing the raster file to look so jagged; I've
had to resize it to about 3 times bigger than the size it comes in.
Tomorrow I will try Erin's suggestion of grouping the layers in the dxf
and scaling them down to match the raster layer. The registration
shouldn't be too much of a problem because it's a really small area
that I know very well.

I have changed my hypsometric tinting
scheme to something a little more dramatic. I have discovered that the
tinting DOES come through when I export the raster data from Global
Mapper. My previous tinting scheme was a little too subtle and it just
didn't show up very well when I was enlarging the raster layer to match
the incredibly huge vector layers. Now that I'm going to do things the
other way around it should look just fine.

BEAVER, how would you
rate the ease of use of Manifold for someone who is just a beginner
with GIS? I find Global Mapper incredibly easy to use; that's one of
the reasons I chose it. I never even heard of Manifold until I started
visiting this forum a few weeks ago. I checked their website and am
disappointed to find that they don't offer a free trial version as
Global Mapper and MAPublisher do. I'm a bit hesitant about shelling out
$250 for a program that I can't even try.

Liz,
If
your going to increase the size of the DEM, you should increase the
resolution on import. If any thing, you want the image to be larger
than you actually need not smaller. You can decrease the size without
degrading the quality as long as the resoltion is high....but you can't
go the other way. Import the vector work next and resize it to the DEM.
You can resize the vector work all you want without losing any quality.
Like I said before, just be sure and hold down the (shift) key when you
are resizing the vector work to the DEM.

You should seriously
consider buying Manifold. Don't worry about it being complicated to
use. It's not. Believe me. Plus, I would bet there are at least 10
forum members who use Manifold and are more than happy to help out.
It's the best deal going.

Global
Mapper is much easier to use than Manifold. I remember learning GM in
couple hours just by playing with it. Not something you can do in
Manifold. It took me at least two weeks to get things going in
Manifold. But you can't relly compare those two. Manifold is much more
powerfull with at lest 10 times more tools and functions.

Going
back to you project, I would not scale the image to DXF as that will
pixelize the image. Always try to scale the DXF which is vector based.
You can use Capture Screen Contents to Image in Global mapper and type
in the image resolution that you're looking for.

"Though I haven't used Global Mapper much for export purposes, I have a couple suggestions from my pre-ArcGIS/MapPublisher days.

1)
Create a reference guide that exports with all your layers. I tend to
always use a file called ""study_area"". Typically I make a polygon that
I know the dimensions of. This can be used in Global Mapper to export
only specified areas. Say your polygon is 5 miles square. You can
export the files out of Global Mapper then scale it appropriately in
Illustrator, i.e. 1 inch equals a mile you would scale your data to a 5
inch square. You can also do this with a line. Then all subsequent data
sets can be scaled to that original layer. I tend to import/place data
layers one at a time. This would for both raster and vector data.

2) Try exporting also to SVG. I find this creates smaller, cleaner files than DXF from Global Mapper.

3)
As mentioned earlier, scale your vector data to the appropriate scale
first, then scale your raster data to the vector data. Watch Global
Mapper on the pixel size when exporting, it doesn't always default to
the maximum resolution of the imagery.

Actually Global Mapper has a better SVG export than any Adobe product!
BUT:
Illy will gulp and spit out nothing visible if you just export real
world coordinates most of the time, as he tries to put them on the
canvas (I´m using CS, any CS2 user might know more about it; with
MAPublisher it shouldn´t be any problem). You will have to scale,
which is an option in the svg dialogue box. "

GM
is one the best user-friendly GIS out there. I always use GM to mosaic,
reproject, and export to a number of different formats, and I'm talking
some big 500 -600 mb rasters!

I really couldn't live without it.

Now,
since I use ARCView and Autocad Map and Global Mapper, I wanna get in
on Manifold. Everyone in these forums raves about it, so I got to take
the plunge and see what that puppy can do! Will prolly order next week.
