Project Design for
Geomatics Engineers
and Surveyors
Project Design for Geomatics Engineers and Surveyors, Second Edition, continues
to focus on the key components and aspects of project design for geomatics and land
surveying projects with the goal of helping readers navigate the priority issues when
planning new projects. The second edition includes new materials on surveying and
UAV, and it is thoroughly updated to keep current with the recent technology and ter-
minology. The two new chapters capture new developments in the rapidly emerging
use of remote sensing and GIS in aerial surveys, mapping, and imaging for small-to-
medium-scale projects, as well as modern practices and experiences in engineering
surveying.
• Provides a simple guide for geomatics engineering projects using recent and
advanced technologies.
• Includes new content on spatial data collection using GIS, drones, and 3D
digital modeling.
• Covers professional standards; professional and ethical responsibilities; and
policy, social, and environmental issues related.
• Discusses project planning including scheduling and budgeting.
• Features practical examples with solutions and explains new methods for
planning, implementing, and monitoring engineering and mining surveying
projects.
Undergraduate and graduate students, professors, practicing professionals, and sur-
veyors will find this new edition useful, as well as geospatial/geomatics engineers,
civil engineers, mining engineers, GIS professionals, planners, land developers, and
project managers.
