The water area surveying and mapping device comprises a floating bearing body, a distance measuring device and a positioning device, the distance measuring device and the positioning device are both arranged on the top face of the floating bearing body, the distance measuring device comprises a direction adjusting part and a distance measuring part, the direction adjusting part is arranged on the top face of the floating bearing body, and the distance measuring part is arranged on the top face of the floating bearing body. The distance measuring part is arranged at the adjusting end of the direction adjusting part, the positioning device comprises a height adjusting part and GNSS equipment, the GNSS equipment is arranged at the center of the top face of the positioning device through the height adjusting part, coordinates of a floating bearing body are determined through the GNSS equipment, then the distance between the floating bearing body and a water bank is measured through a laser distance measuring instrument, and the distance between the floating bearing body and the water bank is obtained. The coordinates of the water bank points can be collected, and the contour of the water bank can be drawn according to the coordinates of the multiple points. The water area surveying and mapping device and the surveying and mapping method provided by the invention have the effect of surveying and mapping without approaching the shoreside.
