Geopak File
1.0Geopak File
1.1Geopak Extensions
GEOPAK file(s) are named for content recognition through filename. The file names consist of eight, or less, alpha-numeric characters with the appropriate extension.
Common file extensions:
xxxxxxxx.gpkRoadway Database File
xxxxxxxx.tinSurface file
xxxxxxxx.prjProject Manager file
1.2Geopak Database File Names
Using the eight-character, or less, alpha-numeric designation, the project file(s) utilize the following naming convention:
JOB {Project Designator}File Extension} where;
JOB35.gpk
would be recognized as:
35……..Project Designator
.gpk……..File Extension
1.3Horizontal Alignment Naming Conventions
Each alignment in GEOPAK has a different letter designator to aid in content recognition. GEOPAK provides one to nine alphanumeric characters for naming alignments. All horizontal alignments, including main lanes, ramp, frontage roads and cross streets follow the following format
ML*…….Main Lanes
CD*………..Collector Distributor
CONN*…….Direct Connector
FRTG*………..Frontage Roads
RMP*………….Ramps
ISCT*………..Intersecting Cross Streets
1.4Vertical Alignment Naming Conventions
Each Profile in GEOPAK will continue the same naming convention as all the Geopak horizontal alignments
Note: Any alignment carried over from IH 30 Pegasus Phase I will utilize their naming convention and is described in Table 1 below:
The following table identifies the names and descriptions of all Geopak horizontal and vertical alignments.

1.5Geopak Horizontal Alignment Stationing
Baseline/Centerline stationing was provided by TxDOT. Stationing was only applied to the baseline.
Alignments designed parallel to the baseline are stationed with a format similar to the baseline/centerline. The new alignment stations are closely correlated with the baseline stations.

The proposed digital terrain model file(s) utilize the following naming convention:
