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.

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.
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.
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.
