CAiCE

CAiCE is no longer being supported or updated. It mayeventually be shelved by Autodesk.

At some point CAiCE may fail to load or run in Windows.

FDOT has no control over these triggers.

As long as CAiCE continues to work FDOT will includeupdated resource files in the state kit to support CAiCE.

What happens if CAiCE is gone tomorrow?

A greater reliance on MicroStation and GEOPAK.

Unlike Data Acquisition, GEOPAK SURVEY is aComplete Package

In FDOT Under Utilized

Can process raw field observations

- Build Control files

- Supports OBS Taping, SOE, Eccentricity

- Uses Ray Hintzs least square adjustments andapplies Geodesy.

Using GEOPAK Survey is an excellent way to importexisting CAiCE Survey Points and Survey Chains intoMicroStation and GEOPAK.

Using the CDGTOV8 Converter has limitations.

- Limited levels all text and the oint s mbol end uon the same level

- CAiCE does not support true type fonts

- file

- Does not build a dataset so surfaces are problematic

GEOPAK Survey requires a project file (PRJ).

Project files (PRJ) control all aspects of data handlingand preferences, including but not limited to:

- SMD file for Roadway or Right of Way

-

- Control file, Projections and Adjustments

- Settings for processing and reduction of raw data

- rea on o a ase s, sua za ons an ca e- Settings for DTM creation

Introducing the Survey Development Model

Was added for the purposes of developing surveyingdeliverables in Civil 3D

QC Inspector considers the SURVRD##.DGN an openfile (will always pass QC).

In the Create File/Project program, will be added to the

list of survey files under Roadway Design/Survey.

Point and Chain Editing can be done directly from the

GPK Navigator

Double Click on the point in Navigator to pull up the pointeditor

Import the Dataset into the GPK

Graphics will be visualized and the GPK file will be

populated with survey points and survey chains

Note that an OBS file, with all CAiCE chain edits, hasbeen created
