Abstract

Applying GIS, GPS, and LiDAR for Urban Infrastructure Renewal Projects
Track: Surveying
Authors: NIJAZ KARACIC

The first decade of the twenty-first century has led many in the surveying profession to adapt to and embrace the technological applications of GIS. The progress made with GPS and mobile LiDAR now allows surveyors to accurately collect more topographic shots than ever before.

Using GIS allows surveyors to visually see and compare datasets as features change over time. This presentation focuses on large scale urban infrastructure renewal survey projects like the Dallas Levees, that protect Dallas from the flood forces caused by the Trinity River, to show how surveyors can bring GPS, LiDAR, and GIS together with the conventional methods used for years. By doing this, comparisons can quickly be made between base and current elevation models.

The audience will see that by bringing these methods together, improvements will be seen in the overall product, time schedule, and most importantly, the client's and surveyor's budgets.
