hey chris!
here is a basic "moving ontop of matrix and camera follow" program:
(its an exerpt from my rpg)

`Chapter 1-Create world |
`--------------------------
`Setup
sync on
sync rate 0
color backdrop rgb(0,0,0)
make matrix 1,10000,10000,100,100
randomize matrix 1,75
position matrix 1,500,5,500
update matrix 1

`Chapter 2-Load all media |
`----------------------------
rem Activate and distance fogging
fog on
fog distance 3000
fog color RGB(0,0,0)
rem make character
make object sphere 1,50
`place player near the center of the matrix
position object 1,500,5,500

`Chapter 4-Main loop |
`-----------------------
do
`player movement and turning
if keystate (17)=1 then move object 1, .50
if keystate (31)=1 then move object 1, -.3
if keystate (30)=1 then yrotate object 1, object angle y(1) - .3
if keystate (32)=1 then yrotate object 1, object angle y(1) +.3
`make it so that the character stays above the matrix
x# = object position x(1)
y# = get ground height(1,x#,z#)
z# = object position z(1)
`render all of above X# Y# and Z#
position object 1,x#,y#,z#
`place the camera at the players position and face it the same angles it faces
position camera x#, y#, z#
`set camera to object orientation 1
rotate camera object angle x(1), object angle y(1), object angle z(1)
`move camera straight up
xrotate camera 90
move camera -70
`set camera back to players angles and move it behind him
`set camera to object orientation 1
rotate camera object angle x(1), object angle y(1), object angle z(1)
move camera -200
`draw changes
sync
`end loop
loop
and what i do for my rpg in loading maps is:
load_map:
M=2
if matrix exist(1) then delete matrix 1
load bitmap "LVLHM3.bmp",1
set current bitmap 1
bw=bitmap width(1)-1
bh=bitmap height(1)-1
masix=(bw*100)*M
masiz=(bh*100)*M
make matrix 1,masix,masiz,bw,bh
smx#=((bw*-500)*m)/2
smz#=((bh*-500)*m)/2
if image exist(1) then delete image 1
load image "LVLHM3.bmp",1
prepare matrix texture 1,1,bw,bh
in=0
`bw-1
for x=bh to 1 step -1
for z=1 to bw
in=in+1
set matrix tile 1,z-1,x-1,in
next z
next x
for x=0 to bw
iz=bh+1
for z=0 to bh
iz=iz-1
h=point(x,iz)
h=(rgbr(h)+rgbg(h)+rgbb(h))/3
set matrix height 1,x,z,h*(m+1)
next z
next x
update matrix 1
delete bitmap 1
return
all its doing is calling an image and making a mesh out of it. and turning it into a matrix.
replace the images that are there with yours. (i found this in codebase it helps a ton!)
also.
right before your main loop put
hope this helps,

(on more thing chris, your heightmap needs to be in bitmap form for this to work. Go into photo shop and make a simple 50x50 thing and make it a bitmap. (remember. when using this the lighter the color the heigher the point goes))
