PVGeo

An open-source python package for geoscientific visualization in VTK and ParaView.

I am the creator of PVGeo, an open-source python package for geoscientific visualization in VTK and ParaView. This library is tailored to integrating post-processed data and models to create more intuitive visualizations of spatially referenced data in the geosciences, especially geophysics.

ESPAtools

Python package for simple loading of Landsat imagery as NumPy arrays

Mobirise

I have created ESPAtools, a lightweight Python package for simple loading of Landsat imagery to provide a convenient and intuitive means of accessing the metadata along side the raw data in a Python environment.

This package is built for use in any Python environment and I have Jupyter notebook examples like the notebook here. I have also incorporated an interface for ESPAtools in PVGeo to make a user-friendly and fast way of inspecting Landsat imagery.

Geophysics in VR

An ongoing project to explore how technologies like Virtual Reality can help scientists make spatial decisions

This is currently an ongoing project to explore how technologies like Virtual Reality can help scientists make spatial decisions. This project leverages ParaView's Virtual Reality capabilities and the PVGeo code library for visualizating geophysical data. We hope to visualize geophysical data and models in VR to: 

  • Develop value of information methodologies in VR for de-risking decision making.
  • Develop a protocol for how VR can be a tool for geoscientists.
  • Address how technologies like VR can help scientists complete their work.
  • Explore what kinds of additional discoveries are made possible by technologies like VR.
  • Statistically analyze interpretations differences for VR vs. traditional visualization techniques.
  • Identify use cases for VR in geophysics.

Tree Roots & GPR

This is a project in which I assessed the feasability of various survey designs using Ground Penetrating Radar (GPR) to image tree root structures in the Critical Zone. Through finding a feasible survey, I hoped to contribute a viable tool for scientists to use in developing an understanding of where tree roots are and how trees are contributing to Critical Zone processes.

Below are a few snippets describing the various survey designs.

Radial Survey Pattern
As we move the GPR along each radial transect, the antennas would theoretically be perpendicular to the direction of the root growth at all times.

The GeoBot
This robot system is designed to be fairly robust to navigate uneven terrains and avoid obstacles, it has a potential for relatively fast GPR acquisition, and the GeoBot has a Differential GPS (DGPS) on board for accurate spatial reference.

The Push Cart
This design uses a SmartCart from Sensors and Software coupled with a Trimble R10 DGPS. The differential GPS continually records the cart's location at every GPR trace. I have maintained under 3cm lateral accuracy with this set up.

Push Cart with Guide Rails
This guide rail system helps a cart operator achieve their assumed path for a rectilinear grid while also allowing the cart to be used with its onboard DGPS. This provides two frames of reference and ensures high spatial accuracy.
