GPS Collection and Data Requirements

The City of Joliet uses GIS (Geographical Information System) technologies to store, manage, and maintain geographic/spatially related data. Likewise, most of the civil engineering community has evolved to the point where the predominating design environment is computer aided design and drafting (CAD). It is the goal of the City to use GIS and CAD technologies to acquire as-built data for all infrastructure installed. It is the responsibility of the contractor to deliver complete and accurate GIS data prior to acceptance of any improvements. The standards below will guide integration of digital engineering CAD drawings into the GIS environment, while maintaining the integrity and positional accuracy of the data.

Blank attribute tables in geodatabase format will be provided by the City for storm, water, sanitary, electric, and dry utility systems. The fields are already formatted and are to be used for providing attribute information that corresponds to the infrastructure.

Requirements for Digital CAD and GIS As-Built Submittals:

· All data shall be in coordinate system: NAD_1983_StatePlane_Illinois_East_FIPS_1201 Feet.

· The scope of mapped infrastructure is to include water main, sanitary sewer, storm sewer, storm sewer outflows, electrical, streetlights, and all other appurtenances required by the City of Joliet.

· Do not rename any of the attribute tables.

· Do not alter the original formatting and structure of the attribute tables or replace them with similar tables.

· Use the correct table for each sewer line, structure type, or other feature.

· All required fields filled in with appropriate data. Additional information entered in the non-required fields is also helpful.

· Correct units and precision used for pipe diameter, pipe length, upstream elevation, etc.

· Correct code from the lookup tables used when required. The lookup tables can be found in in the metadata associated with the geodatabases. Whenever possible use the code that most accurately describes the item.

· Removed or abandoned features need to be denoted as such within the attribute table.

· All sanitary and storm sewer shall be drawn in the direction of flow.

· Collect GPS points of structures prior to burying.

General Notes:

· The lookup tables are not linked to the attribute tables, so they are used as a reference.

· Adhere to the requirements in any “type” column in the Attribute Table Requirements.

· This formatting must be adhered to for the attribute information to be used properly.

· Excel (.xls) files can be accepted for the attribute tables if the formatting is kept the same and none of the field names are changed or deleted, however the original geodatabase file format is preferred.

· If it is unclear which attribute tables should be used or how to code any of the required fields, please consult with the City prior to delivering your digital data submission.

· Data shall be submitted in full GIS geodatabase format or AutoCAD drawings with Civil 3D Models.

· Refer to external City documents regarding more detailed CAD and GIS standards and guidelines.
