Abstract: The effective forest fire monitor and localization system is one way of preventing and reducing forest fire. Based on the secondary development components, ArcEngine and Geodatabase, the function of fire monitor and fire localization was completed in this system. The functions of monitor site selection, fire localization by one monitor, coordinated control between the digital cradle head and the 3-D map and aided analysis were implemented in this system. The stability and the basic functions of the system were tested in the Bailang Forestry Center in Inner Mongolia. The system showed stable operation performances, and could realize the expected functions.

Key words: ArcEngine, forest fire monitor, site selection, one-monitor localization
