Description of Methods for Identifying Charcoal Hearths along the Blue Mountain of Pennsylvania.

This is a pdf document (created with LibreOffice- version  6.0.2.1 (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.
