Hi Dan,<br>
<br>
first of all you have to make the decision to use either local or
global reference system. You can not mix them. <br>
<br>
As you are planning to use GIS data I would recommend to use global
coordinate systems. The advantages are:<br>
- you can mix coordinates in different coordinate systems<br>
- you can choose the output coordinate system in therion<br>
- therion can calculate the magnetic declination (if you specify the
date whem the readings were done) <br>
<br>
What you need to do is:<br>
- you need a rectangular coordinate system (ie UTM,...) (not good is
for instance lat-long) <br>
<br>
- in your measurement data you have to specify the coordinate system
(command "cs"):<br>
survey Fahrstuhlschachthoehle<br>
centreline<br>
date 2009.11.07<br>
cs UTM33<br>
fix 2.20 0275873 5287674 1833<br>
...<br>
<br>
<br>
- you have also to specify the coordinate system in your surface
definition:<br>
surface # Deklaration des Geländemodells<br>
# coordinate system<br>
cs EPSG:31468<br>
grid 4500500 5284700 10 10 100 100 # grid x_Minimum y_Minimum
x_res y_res n_col n_row<br>
# calibrated surface texture<br>
bitmap ./dop.jpg [0 0 4500500 5284700 5000 5000 4501500 5285700] <br>
#<br>
# Height matrix<br>
1255.32 1259.45 1262.32 <br>
...<br>
<br>
<br>
you can also find some more information on how to build 3D models

<br>
Best regards<br>

<br>
PS: you can also use "cs" in your thconfig file (in case to produce
output in different coordinate systems)<br>

Bruce, when authors of Therion created it nobody nor MartinB
and Stacho could imagine what they did. Therion means in
ancient Greek something as big wild beast and they did not
suspect what they runned out. ;o)<br>
<br>
The users as you just explore another unexplored parts of
therion's den for rest of us. Thanks!<br>
