Data Conversion: Submodels

The data conversion project, completed in the fall of 2001, includes data from 13 different data areas or submodels.  These submodels include:

Landbase

A key effort concluding in the spring of 2001 was the processing and creation of the digital orthophotography, which allows the access of aerial photography as a "backdrop" behind any other GIS data features.  In addition, the Landbase submodel holds data features like Hydrography, Contours, Geodetic Monumentation Points, Soils, Digital Terrain Model, and the Public Land Survey System.

Cadastral

Cadastral is defined as the showing or recording property boundaries, subdivision lines, buildings, and related details.   As such, within REGIS, the Cadastral Submodel contains much of the data features associated with the parcel fabric. It also includes Easement data layers.  Many of the data layers found within this submodel are maintained by the REGIS Land Base Administrator, the Property Description & Mapping Division found within the Equalization Department of Kent County.

Transportation

The Transportation Submodel contains features like Center of Pavement, Railroads, Bridge data, Parking Lots and Ramps, and also the ITP's (Interurban Transit Partnership) Bus Route data.  Participants and partners contributing to the data found within this submodel include the ITP, GVMC Transportation Division, Kent County Road Commission, and the Michigan Information Center.

Storm water

The Stormwater submodel is designed to manage the data associated with Public Stormwater Management.  Those contributing to this submodel include many local Stormwater Management Divisions or Engineering Departments, but also the Kent County Drain Commission and the Kent County Road Commission.  This submodel modeled to hold both natural and enclosed drainage features.

Sanitary Sewer

The Sanitary Sewer submodel is designed to manage data associated with Public Sanitary Sewer Systems.  Again many local Engineering and Environmental Protection Departments are contributing to this submodel.

Water Utilities

The Water Utilities submodel is designed to manage data associated with Public Water Systems.  Again many local Engineering and Water Departments are contributing to this submodel.

Electrical Utilities

The electric submodel was designed to hold features associated with Street Lighting networks.  This submodel was designed for the City of Grand Rapids, but has been populated for other participants too.

Steam

This submodel was designed to hold the features associated with the Kent County Steam System that feeds the Downtown Grand Rapids area.

Planning

The Planning Submodel focuses on features associated with Public Planning Divisions.  Examples of data layers include Planned Land Use, Land Use and Cover, Zoning, Parks and Recreational Sites, and Trails.

Political Boundaries

Within the Public Sector, there are many boundaries or districts that are critical to a public sector GIS. These features and this submodel include features such as Government Unit Boundaries, School Districts, DDA districts, Renaissance Zones, Wards and Precincts, and Commission Districts.

Public Safety

Although much of the data layers associated with this submodel will remain confidential to Public Safety officials, data has been collected for both Law Enforcement Departments and Fire Protection Departments.
