Challenges of Traditional Earthwork Surveying
Difficult Access to Complex Terrain
Steep slopes and soft ground make it hard for personnel to access, leading to data gaps and estimation errors.
Time-Consuming Fieldwork
Traditional GNSS-RTK takes 2-3 days per square kilometer, with high labor intensity and inevitable human errors.
Inconsistent Records
Multi-phase data comparison is difficult, dynamic construction monitoring is lacking, causing cost overruns and delays.
