This is a pdf document (created with LibreOffice- version 22.214.171.124 (x64) ) that describes the methods for identifying charcoal hearths from the 19th century along the Blue Mountain in eastern Pennsylvania. The area is identified in a GeoJSON polygon (http://doi.org/10.5281/zenodo.1252418)
The methods herein were used to produce:
a digital elevation model (DEM)- http://doi.org/10.5281/zenodo.1252441
a hillshade model- http://doi.org/10.5281/zenodo.1252520
a slope analysis- http://doi.org/10.5281/zenodo.1252977
These were used to identify charcoal hearths that are recorded in this GeoJSON vector file- http://doi.org/10.5281/zenodo.1252985
Please use this document to understand how these files were created and how to reconstruct this data.
