Paul,

>Thanks for helping with the mcidas upgrade.

No worries.

>I understand that there are

Perhaps the best help would be some examples that you can use and build
on.

Here goes:

1) draw a map of the continental US in CONformal projection and overlay
   it with US Interstate Highways

   a) two step method

   SF 1
   ERASE
   MAP USACONF 1
   MAP SAT 7 FILE=OUTUSINT

   b) single step method

   SF 1
   ERASE
   MAP USACONF FILE=OUTLUSAM OUTUSINT MCOLOR=1 7

2) draw a map of IL in magenta and overlay it with interstates, US highways,
   and state roads all in different colors

   a) multistep method

   SF 2
   ERASE
   MAP IL PRO=CONF
   MAP SAT 7 FILE=OUTUSINT
   MAP SAT 4 FILE=OUTUSHIW
   MAP SAT 5 FILE=OUTSTRD

   b) single step method

   SF 2
   ERASE
   MAP IL PRO=CONF FILE=OUTLUSAM OUTUSINT OUTUSHIW OUTSTRD MCOLOR=1 7 4 5

3) much like the other examples, put up a map of FL counties and overlay
   it with a map of state outlines, but have the line width of the
   state outlines be 2

   SF 3
   ERASE
   MAP FL PRO=CONF FILE=OUTLCNTY MCOLOR=5
   MAP SAT 1 ST=FL WIDTH=2

4) Also try:

   SF 3
   ERASE
   MAP FL PRO=CONF ST=FL COU=ALL MCOLOR=5

   And:

   SF 3
   ERASE
   MAP FL PRO=CONF ST=FL COU=ALL MCOLOR=5 DOMAIN=YES
   MAP SAT FILE=OUTUSINT MCOLOR=7

Now, any map you can generate can be put into your MAP.USER file and
assigned a mnemonic so you can easily plot it.  Add the following to
your MAP.USER file:

ROADS  OUTLINEFILE=OUTUSHIW OUTUSINT OUTSTRD \
       PROJECTION=SAT \
       MCOLOR = 5 3 2

And then plot ROADS on top of another map:

SF 1
ERASE
MAP IL 1 PRO=CONF
MAP ROADS

Notice that you have to have some navigation in the frame before you can
plot the ROADS.  To illustrate the point, try putting up a satellite
image and plotting ROADS on top of it.

The new MAP outline files in the distribution go well beyond roads.
Here is the list:
