USER NOTES:

Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling purposes. Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the county level.1:24000 data should NOT be used for high accuracy base mapping such as propertyparcel boundaries. 

1:100000 scale datasets are recommended for projects that are at the multi-county orregional level. 

1:250000 scale datasets are recommended for projects that are at the regional orstate level or larger. 

Vector datasets with no defined scale or accuracy should be considered suspect. Makesure you are familiar with your data before using it for projects or analyses. Everyeffort has been made to supply the user with data documentation. For additionalinformation, see the References section and the Data Source Contact section of thisdocumentation. For more information regarding scale and accuracy, see our web pages at:

DATA LINEAGE SUMMARY:

Original 1934 hardcopy map was scanned in quads using a UMAX Power Look 2100xl
scanner. The hardcopy map was scanned at 300dpi (dots per square inch). The
quads were recombined to form the original map in Photoshop 6 and saved as a
tiff image. The tiff image was then georeferenced using a DRG100.img image
using ERDAS Imagine. A subset of the panhandle was taken from the tiff image
and georeferenced as well using the DRG100.img. The two georeferenced images
were then mosaiced together using ERDAS Imagine. The mosaiced image was then
subsetted using an AOI of the State to remove the extra border. The final
State.img was imported into Arc GIS and a shapefile was created of the
different forest types through digitizing, at a scale of 1:100,000. Any sliver
polygons were removed using the eliminate/reselect command in arc.
