DigitalGlobe also introduced the Crisis Event Service, which was launched in July 2009, enabling users to quickly access images before and after natural disasters around the world. These images are useful for emergency planning, risk assessment, temporary area monitoring, damage assessment, and rehabilitation programs.

International consulting firm COWI (Denmark) also introduces terrain laser technology from overhead to determine the topography to a few centimeters. In addition, COWI's thermal mapping technology helps determine the difference in temperature in a given area to provide a suitable solution.

COWI's 3D imaging technology also transforms urban planning drawings into three-dimensional models, enabling users to easily visualize real patterns. According to Nguyen Tuan Hung, director of the Department of Geodesy and Cartography, Ministry of Natural Resources and Environment, although Vietnam has not yet decided to use the technology introduced above, this is an opportunity for ministries and agencies to learn and choose.
