Electromagnetic Transfer Function File Conversion Utilities (EMTF FCU) Electromagnetic Transfer Function File Conversion Utilities (EMTF FCU)

Magnetotelluric impedances and other similar transfer functions are important for geophysical interpretation and for space weather hazards. I helped develop and continue to curate a database known as IRIS EMTF, http://ds.iris.edu/spud/emtf which uses something called EMTF XML format for storing the data. EMTF FCU v4.1 software consists of a set of freely available format conversion tools...

Floodplain and Channel Evaluation Tool (FACET) Floodplain and Channel Evaluation Tool (FACET)

The Floodplain and Evaluation Tool (FACET) is an open-source python tool that maps the floodplain extent and derives reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs).

Floodplain and Channel Evaluation Tool: FACET Floodplain and Channel Evaluation Tool: FACET

FACET is a Python tool that uses open source modules to map the floodplain extent and derive reach-scale summaries of stream and floodplain geomorphic measurements from high-resolution digital elevation models (DEMs). Geomorphic measurements include channel width, stream bank height, floodplain width, and stream slope. FACET allows the user to hydrologically condition the DEM, generate...

Wild horse aerial double observer survey analysis R script Wild horse aerial double observer survey analysis R script

This R file estimates horse abundance by analyzing data from simultaneous double-observer aerial surveys. The code follows analytical procedures established by Dr. Bruce Lubow, the statistician contracted for many years by Bureau of Land Management (BLM). Field data collection techniques are described in the Standard Operating Procedures (SOPs), which is a separate document. Download the...
