Geospatial engineering utilizes geographic information systems $($GIS$)$ and remote sensing technologies to analyze and manage spatial data. Explain the principles of geospatial engineering, including GIS data collection, data analysis, and data visualization. Discuss the applications of geospatial engineering in civil engineering, such as land surveying, infrastructure planning, and environmental monitoring, highlighting the benefits of using spatial data for decision$-$making. Additionally, describe the emerging trends in geospatial engineering, such as $3$D modeling, LiDAR technology, and UAVs, emphasizing their potential to revolutionize the field.
