April 2017

Touching Spatio-Temporal Data Through Haptic Robots. Adding More ‘Sense’ to GIS

April 06, 2017
2:00 pm - 3:00 pm
Eller O&M Bldg., Room 807

This presentation will introduce the use of haptic robots to ‘touch’ spatially distributed data of complex mulit-variate systems. The technology to dive into these systems has been developed by the Haptic group at the Stochastic Geomechanics Laboratory (SGL).

October 2017

Advanced Geomorphometric Approaches for Understanding Mountain Environments

October 05, 2017
3:00 pm - 4:00 pm
Eller O&M Bldg. Rm 807

The relationship between topographic form and surface process, though qualitatively well-­understood, is numerically poorly characterized. Identifying, mapping, and characterizing surface processes using machine visualization and automation demands that topographic forms be formalized in mathematical language and that relationships to the polygenetic heritage of geomorphic form be evaluated in a hierarchical, context-­sensitive manner.

Ground Penetrating Radar: Uncovering the ‘Hidden Half’

October 19, 2017
3:00 pm - 4:00 pm
Eller O&M Bldg. Rm 807

Alfredo Delgado Deparment of Soil and Crop Sciences, Texas A&M University Graduate Student Abstract GPR is an existing and rapidly evolving technology that can be used as a high throughput, non-­destructive-­3­‐dimensional imaging method – for quantifying root mass. With the ability to detect subtle differences in the soil media, GPR has often been utilized as a small cross-­section near-­surface object detection tool. GPR technology has been utilized to nondestructively image…

November 2017

Advances in LiDAR Data Processing: From Waveform to Photon Counting LiDAR

November 02, 2017
3:00 pm - 4:00 pm
Eller O&M Bldg. Rm 807

the overall goal of the research is to develop algorithms for FW and PCL data processing to explore their potential in real-world applications such as tree species identification and to quantify the uncertainty of model building, data processing, and applications steps.

Z-Curve: A Geographical Projection of GNSS (Global Navigation Satellites Systems) Signal, Time, and Position

November 16, 2017
3:00 pm - 4:00 pm
Eller O&M Bldg. Rm 807

This talk presents a novel geometric model to characterize the zero-­crossing curve (or z-­curve) for the signals emitted by a pair of GNSS satellites, which is the intersection of the Earth surface and the z‐surface that has zero difference in its pseudoranges to the two satellites.

Applications: Environment
Science: Education, Engineering
