GIS & Addressing

The acronym GIS stands for Geographic Information System. It is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographically referenced data. In its simplest form, GIS is a map.

The District GIS effort was started in 1992 as an effort to build an accurate map for rural address assignment, and to locate 9-1-1 callers. In cooperation with the City of Lubbock and Lubbock Central Appraisal District, LECD was able to create a unified dataset of geographic details, while eliminating duplication of work done by multiple agencies. The District's GIS department encompasses several key functions.

Mapping

The District mapping effort was originally started in order to help with rural address assignments and locate 9-1-1 callers.

In recent years, the focus has shifted away from data collection and creation to data validation and maintenance. With the advent of new mapping and analysis technology, the District has been able to hone the accuracy and precision of its map data.

The GIS department continues to work closely with local entities, exchanging data and offering assistance when needed. Map data developed by the District is routinely shared in both print and digital form.

Addressing

The District is designated as the sole addressing authority for the unincorporated areas of Lubbock County. Thorugh a project which lasted more than a decade, the District converted all rural route designations in Lubbock County to physical addresses.

An addressing scheme was created and implemented by the District, allowing for any physical structures to be addressed, including new construction, housing developments, and new businesses.

Databases

The 9-1-1 system requires many databases in order to function properly. The care and maintenance of these databases allows for accurate addressing, especially in the rural areas.

Two of the main databases administered by the GIS department are the Master Street Address Guide (MSAG) and the Automatic Location Identification (ALI). These sets of records help define the valid addresses within the District and provide information on 9-1-1 callers when they request help.

County Road Signs

In 1994, the District received a grant from the State 9-1-1 Commission for use in rural addressing projects. The District used this funding to launch a county road sign program. After receiving approval from the Board of Managers, the District and Lubbock County entered into an interlocal agreement in which the District provides the materials and Lubbock County supplies the labor necessary to install the signs.

This ongoing project ensures there is adequate signage in the rural areas of Lubbock County for first responders to be able to locate those in need of emergency help and provides benefit to the community as a whole.
