Hi Nate and everybody,
I am using gzbuilder and DEMs (got them from internet) to create an outdoor
map. Everything works fine, now I need to be able to pre-load this map into
the robot so i need a clear ascii file that will hold (x,y,z) coordinates
for each point on the map.
So far I tried modifying gzbuilder so beside creating a *.gzb file (which is
in network byte order) I am also creating a file that is readable. So I am
getting Easting, Northing, X,Y,Z-offsets, Vertex/Index counts, etc.
This is a small output of the file:
############
Gazebo Version : 0.700
Easting: 68079.718750 Northing 4161663.500000
X offset: 0.000000 Y offset: 0.000000 Z offset: 0.000000
Vertex Count: 207249
Index Count: 464255
ODE Index Count: 1238016

My question is what these Vertex, Index and ODE Index counts represent?? (I
read some documentation but I still fully dont understand it) And how (if
possible) from them I can construct (X,Y,Z) coordinates for each point on
the map?
Also, I am using SDTS format of DEM so if anyone knows any other way of
converting this format to something that would be easy to represent as
(X,Y,Z) please let me know.
(I dont need to use gazebo/gzbuilder to extract this map so if anyone knows
any software that can convert SDTS to (x,y,z) also would help)
Any suggestion is very appreciated !
