The scanned maps are provided by USDOI - GLO at their website glorecords.blm.gov. They were downloaded as GeoPDFs or JPEG2000, depending on what was available. The maps were then convereted to GeoTIFF using GDAL_TRANSLATE. The TIFFs were then georectified using ArcGIS 10.3, using the public land survey as the reference data. The resulting TIFFs had a cell size of 6.6 feet, which was resampled to 5ft. and had the collars removed. Finally, the maps were mosaicked in ArcGIS.
2015-03-04T00:00:00
Overall completion was reviewed by looking at the mosaic tiles in ArcGIS, reviewing the seams for gaps or errors.
