Leica GSI - Format
The required format of a GSI file containing DTM triangles is described below.
Header of the DTM file
The header is the first line in the GSI file. There must be one header line per
file in the follwing form:
DXF-Format, continued
• LISCAD generated DXF File
An AutoCAD DXF file containing
3DFACE may be generated by users
of Leica’s LISCAD in the following
manner:
1) In Terrain Modeling/Display/
Features…Select the Model tab –
Turn on only the triangles.
2) In Terrain Modeling/Display/
Groups… - Turn off all Groups but
DEFAULT.
3) In CAD Output/Settings/CAD
System – Choose AutoCAD DXF.
4) In CAD Output/Settings/Codes… -
Deselect all the options on all the
tabs.
5) In CAD Output/Settings/Models…-
Set Labels to none, Contours to none,
and activate the Triangles check box.
6) In CAD Output/Output! – Select the
Options button – In the General tab
turn off all option check boxes except
Model and use Default for All, in the
AutoCAD tab deselect all check
boxes except 3Dimensional. Then
click OK.
7) Click OK and create the DXF file
that contains only the 3DFACE’s.
41....+000JOBID 42....+DTMNTWRK 43....+DTMCOORD 44....+00001000 45....+00001000
WI41 Job identification, maximum 8 characters, may be defined by
user.
WI42 Identification of DTM file, may not be changed by user. This
entry must be +DTMNTWRK.
WI43 Identification of principal point type, may not be changed by user.
This entry must be +DTMCOORD.
WI44 Optional easting offset. May be defined by user.
WI45 Optional northing offset. May be defined by user.
If used, easting and northing offsets are added to the
coordinates of the triangle vertices. These values have no digits
to the right of the decimal place.
For example if units are set to (m), "44….+00001000" means
that 1000m will be added each Easting coordinate.
