Currently,there are many problems in water conservancy surveying,such as high costs,long data acquisition cycles,and difficulty in real-time monitoring.This article first analyzes the key points of water conservancy engineering and hydrogeological exploration,and then combines remote sensing technology and geographic information system to survey and analyze the rock layers and terrain of dam foundation engineering.Finally,it applies the water conservancy engineering in county A as an example.The results showed that the study took approximately 3.8 seconds to draw 2 500 dynamic engineering geological and hydrogeological elements,and the drawing speed was relatively fast.And it can accurately draw engineering rock and terrain information,providing reference for the smooth development of engineering construction.
