CompassData specializes in the creation of accurate GIS base maps for Enhanced 911 (E911) applications. Road centerlines with accurate attribute information form the core of most E911 GIS databases. CompassData provides the equipment and staff to assist your agency in map creation and maintenance.
Our proven quality control processes ensure the accuracy of both positional data and attributes. CompassData will collect GIS features in the field and combine new data with existing data to create an enhanced base map for your GIS. This “feet on the street” approach ensures that your GIS and E911 data will be accurate and reliable.
E911 (E911) Related GIS Layers and Services:
Road Centerline Mapping and Addressing
CompassData utilizes GNSS equipped vehicles and aerial imagery (if available) to quickly and accurately capture road centerlines and related attribute information. Additionally, CompassData can verify your existing GIS data for accuracy and standards adherence, and merge it with the newly collected data, to create a complete street centerline base map with addressing. A completely addressed and networked road centerline map will allow you to geocode and route vehicles accurately and quickly.
Structure Mapping and Addressing
CompassData utilizes GNSS equipped vehicles, laser rangefinders, and aerial imagery (if available) to quickly and accurately capture structures and related address attribute information. A fully addressed and attributed structure map allows users to pinpoint landline 911 calls to a specific structure.
Cell Tower Mapping
CompassData has developed methods to quickly and accurately collect the position of cellular towers and their antennas. By using trained field personnel and sophisticated location devices, CompassData can deliver a product to help wireless carriers meet current FCC requirements.
Public Safety Boundaries
In addition to our strong GNSS cellular tower mapping skills, CompassCom has the ability to develop and maintain public safety boundary layers including:
- Fire districts
- Ambulance service boundaries
- Law enforcement areas
- Emergency service boundaries
This boundary information nicely supplements cell tower/site information, helping PSAPs to quickly and effectively dispatch correct emergency service personnel to all locations.
After completing the initial data collection, CompassData can maintain and update data for you. Given the increased growth and change that occurs throughout our communities, GIS base maps require constant updating and maintenance to ensure accuracy.
CompassData staff has experience working with local governments, emergency boards, and response entities regarding GIS updates to road centerlines, addressing MSAG to map comparisons, and other E911 related information.
