Mobile mapping refers to the collection of geospatial data using mapping sensors mounted on moving platforms such as cars, marine vessels or airplanes. Mobile mapping systems utilize GNSS technology combined with Inertial Navigation Systems (INS) to enable the rapid and accurate calculation of continuous 3D position, velocity and attitude (roll, pitch and yaw). The time synchronized navigation sensors integrate with digital imaging sensors to enable the direct and precise mapping of landscapes, objects or features.
The recent advances in GNSS, INS and digital camera technology are driving the explosion in mobile mapping applications all around the world. The use of Internet and wireless communication networks facilitates this growth by allowing quick and efficient transfer and processing of data. Online digital maps, geo-reference images, videos and GIS data are all examples of mapping products that rely on the precision geospatial data collected from mobile mapping systems.
Additional examples of mapping applications include:
- Accurate assessment of road or highway conditions for emergency response planning
- Internet mapping applications incorporate aerial photographs and satellite images to develop online mapping systems and street level views
- Location aware PDA systems (think applications that alert you when you are approaching your favorite coffee chain)
- Road mapping and highway facilities management by local and federal governments
- Military and defense applications that survey changes in landscapes or movement of assets or troops
- Corporate asset and infrastructure management
NovAtel's tightly coupled SPAN® GNSS/INS technology is utilized by many in the mobile mapping industry for reliable, highly accurate 3D position, attitude and velocity measurements at data rates up to 200 Hz.
