OBJECTID                        Identifier automatically generated by ArcSDE
FK_PROJECT                      Foreign Key from projects table that uniquely
                                identifies the project throughout the ETDM process 
SHAPE                           Field automatically generated in ArcSDE to store
                                information about the feature shape

This data set is intended for planning purposes only. Line work locations represent the general vicinity of the proposed project and are not intended for design or construction. Information describing the projects is stored in a separate Oracle table, T_PROJECT. This table can be related to the project lines by the FK_PROJECT field. Basic information about the projects and segments has already been joined to the line work in the SV_SEGMENT data layer.

Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the multi-county or regional level.

1:250000 scale datasets are recommended for projects that are at the regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.

DATA LINEAGE SUMMARY:

Project segments are incorporated into the ETDM project database from information provided by FDOT districts and MPOs. Three mechanisms are available for updating the ETDM project database:

1. On-line Project Input – Enables users to identify the location of the needed/planned project on an aerial photograph and enter information about the project into the database by using on-line forms. This application uses USGS Digitial Orthoquarter Quads as the base for digitizing.
2. On-line State Project Identification – Transfers existing information from the FDOT digital base map to the ETDM database. The application allows users to identify existing segments in the existing roadway network, describe the proposed project, and automatically extract information from the digital base map to the ETDM project database. The FDOT digital base map is developed from 1:24,000-scale map sources
3. Batch Upload Utility – This application transfers existing digital data electronically from the MPO databases to the ETDM project database. Source scales vary depending on the specific MPO.

The project lines are created by merging segments together based on the FK_PROJECT id.
