What can GEOPAK do for you?

• Process surveys
• Create digital terrain models
• Store horizontal alignments
• Store vertical alignments
• Process cross sections
• Plan production
• Calculate quantities
• Etc. Etc. Etc.

3
Introduction - File Names

• Job.gpk
• Binary file created from COGO
• Multiple users can access at same time
• All geometry elements are stored here
• Name must be up to 3 alphanumeric characters
• Usually only have one file per project
• Fname.ioc and Fname.ooc
• .ioc - ASCII input file for loading data into
  COGO
• .ooc - ASCII output file created with COGO
• Fname limited to 5 characters
• - job number
• oc operator code (users initials)

4
Introduction - File Names

• Fname.inp
• ASCII file for running GEOPAK processes
• Fname.dat
• Binary file containing string and point
  information to be used for creating a digital
  terrain model (DTM)
• Fname.tin
• Binary file containing triangular surfaces, also
  known as the DTM
• Project-name.prj
• Binary file for each project
• Stores information for Project Manager

User Preferences
6
User Preferences

• Working Directory
• Identifies where data files for a particular
  project can be found
• If field is left blank, GEOPAK uses the directory
  where the open MicroStation file is located
• Feature Preferences
• Defines how visualized COGO elements will be
  displayed
• COGO Preferences
• Job Directory identifies where GPK file is
  located
• Superelevation Preferences

7
Project Manager

• Associates project with COGO job , users,
  working directory and project files
• Leads user through work flow
• Remembers things so you dont have to

Horizontal Geometry Tools

• Coordinate Geometry (COGO)
• Graphical COGO
• Horizontal Alignment Generator
• Store Graphics

Store points, lines, curves, spirals, chains,
parcels and profiles
11
COGO

• Stored within Job.gpk
• Visualizes computations on screen (if desired)
• Records commands to file (if desired)
• Able to calculate new elements based on existing
  COGO elements
• COGO information is referenced by many other tools

12
COGO
Navigator
13
COGO Navigator

• Easily view and edit COGO data

14
Graphical COGO

• COGO must be open to use tools
• MicroStation look and feel
• Graphically stored and identified
• Double precision solutions
• Stored within same Job.gpk as COGO
• Visualizes commands on screen (if desired)
• Shows commands in COGO dialog
• Automatic element name generation, but user can
  modify

15
Horizontal Alignment Generator

• COGO must be open to use tools
• MicroStation look and feel
• Stored within same Job.gpk as COGO (if
  desired)
• Visualizes commands on screen (if desired)
• Shows commands in COGO dialog
• Automatic element name generation from
  preferences
• Extensive alignment design options

16
Vertical Geometry Tools

• Ground Profiles
• VPI Based Vertical Alignment Design Tools
• Component Based Vertical Alignment Design Tools

Store profiles
17
Existing Ground Profile

• Determines existing ground elevation from TIN at
  user defined intervals along chain
• Stores profile in COGO
• Able to store offset profiles
• Option 1 - Pre-2001 tool Ground Profile
• Option 2 - 2001 tool Draw Profile
• Must have chain stored already to use either tool

18
Existing Ground Profile
19
VPI Based Vertical Alignment

• Must reference previously stored chain
• Able to distort horizontal/vertical scale
• Profile cell used for reference
• User can define Grade, design speed, K-value,
  elevation and station values
• Dynamically manipulate VPIs and curves

20
Component Based Vertical Alignment

• Requires Active Chain Control tool activated,
  COGO session open, and Profile Cell identified
• Able to place lines and curves individually
• Able to manipulate previously placed elements
• Stores profile into COGO
• Can import profile from COGO also
• Profile Cell Control enables user to define size
  of cell unlike VPI Based tool or Design Comp.
  Manager

21
Pattern Lines

• Placed along horizontal alignments
• Designates location of cross sections

22
Existing Ground Cross Sections

• Able to read pattern lines by station, design
  file or existing cells
• User defines symbology

23
Existing Ground Cross Sections

• Multiple surfaces allowed
• User defines symbology

24
Proposed Cross Sections

• Uses information already set up horizontal and
  vertical alignments, pattern lines, shapes and
  existing ground
• Reads criteria files to create proposed elements

25
Earthwork

• Draws graphical shapes on cross sections
  representing end areas
• Calculates volumes by end-area method
• User defines type of material by symbology
• Quantity text file can also be created and then
  used to place cut/fill areas and volumes on cross
  section sheets

26
Labeling Tools

• Plan view, profile or cross section labelers
• Intelligent labels XYZ coordinates, chain name,
  profile name, station, offset, direction, length,
  radius, elevation, grade, etc.
• Able to customize user inserts list
• Using styles can help with consistency
• Able to edit and move previously placed labels

27
Design Computation Manager

• Allows user to standardize graphical elements for
  drafting and pay item quantities
• Uses hierarchical database (Filename.ddb)
• Seven modes display, design, set, compute,
  shape, pavement marking and preferences
