January 18, 2013 305 GEOPAK Digital Terrain Models 305.1 General The naming of GEOPAK Digital Terrain Models (DTM) is defined as shown in the table below: Digital Terrain Models (DTM) - .tin Aerial Mapping Existing - nnnnnXAE## Bridge Deck/Surface Existing - nnnnnXBR## Bridge Deck/Surface - Proposed nnnnnPBR## Combined Aerial and Ground - nnnnnXCB## Survey Existing Ground Survey Existing - nnnnnXGR## Proposed - nnnnnP## where: nnnnn = 5 digit PID number ## = 2 digit number 01, 02, 03, . . . 306 GEOPAK Coordinate Geometry Databases 306.1 General When coordinate geometry calculations are processed in GEOPAK, the resulting geometric elements are stored in a separate binary file. This Coordinate Geometry (COGO) database is then used by other GEOPAK processes for a variety of tasks. Each project, regardless of its size, shall have one COGO database (.gpk file) containing all project data processed through GEOPAK Survey or GEOPAK COGO commands. For projects involving multiple locations or multiple design alternatives, it is permissible to use separate GPK files for each location or alternative. The naming of the GEOPAK Coordinate Geometry Database files submitted to ODOT shall be as follows: GPK Files - .gpk GEOPAK Coordinate Geometry - Database Job###.gpk where: job = GEOPAK Naming Convention ### = 3 digit route number or first three characters of street name 82 ODOT CADD Engineering Standards
306.2 GEOPAK COGO Element Names January 18, 2013 To facilitate the efficient sharing and transfer of COGO information between consultants, ODOT, and contractors, the GEOPAK COGO Element Names detailed below have been established. COGO Points Bridge aBR## Centerline Station or Station Equation aCS## Construction Limits aCN## Curve PC aPC## Curve PT aPT## Design aDN## Drainage aDR## GPS GP## Miscellaneous / Junk aJK## Monument MN## Property PP## Right of Way Existing RE## Right of Way Proposed aRP## Roadway Point of Intersection (PI) aPI## Survey SV## Utility Location UT## where: a = Alternate A, B, C, . . . (if applicable) ## = Two or more digit number 01, 42, 541, 2235, etc. Notes: GEOPAK supports alphanumeric point numbers to a maximum of nine characters. Alphanumeric point numbers must have an alpha prefix and a numeric suffix. For example, 123abc is not acceptable, while abc123 is supported. The number portion must be greater than zero, i.e., abc0 or abc000 are not acceptable. Also, do not use special characters, such as %,*,
