Montana, Wyoming, and Idaho Historical Imagery

As a research associate, I helped to generate a continuous historical imagery product for Montana, Wyoming, and Idaho using imagery from the USGS single frame archive. I supported the final product by creating workflows and data pipelines using software listed below.

Project Description

The final products for this project were a single orthorectified historical imagery using the earliest high-resolution images from the USGS single frame archive, a DEM derived from the rendered image, and the 3D model used to produce the image. I supported the project, led by Scott Morford, PhD, by developing scripts, pipelines, and workflows using Agisoft Metashape, ArcGIS Pro, QGIS, MATLAB, R to georeference and process more than 30,000 individual images for multiple projects. Specifically, I performed georeferencing in QGIS and ArcGIS Pro and maintained ground control points and performed quality control analysis in R. In Agisoft Metashape I generated point clouds, 3D models, DEMs, and orthorectified images using 18,000+ images selected for the final imagery product for for Montana, Wyoming, and Idaho.

About the Web Application

This web application was developed by project lead Scott Morford to highlight the final imagery product in the context of tree conifer expansion between the 1940s and 1950s and present day.
