This artical provides three methods for identifying the map-sheet number for the drawing area.The methods are returning home position,segementing slope-assessment with the same side,projection inversion-assessment of inside map neat line based on the theoretical geographic grid.The cartographic drawing corresponding to a certain projection can be mapping correctly by these methods.The methods can be used to query the map sheet number of the geographic information data within the drawing area.
【Key Words】: cartographic region projection inversion fundamental geographical information data query map-sheet number
