These images were converted from GeoPDF into two GeoTIFF formats (GeoTIFF topographic maps with a collar containing scale and other information, and collarless GeoTIFF topographic maps) by the University of Rhode Island Environmental Data Center. Purpose: These topographic maps were completed by the USGS to update base map data for the state of Rhode Island.

Two formats created with the use of Global Mapper version 16 scripting environment, topographic maps with a collar, and topographic maps without a collar. The following steps detail how this was accomplished. First, the following script was modified from a USGS Topo GeoPDF Layers to GeoTIFF workflow. This was then run in Global Mapper version 16. This created collarless GeoTIFFs from the GeoPDFs that were downloaded from The USGS US Topo and Historical Topographic Map Collection. GLOBAL_MAPPER_SCRIPT VERSION=1.00 UNLOAD_ALL // Loop over all GeoPDF files in the directory and convert them to GeoTIFF DIR_LOOP_START DIRECTORY="."

The residual collar results from TIFF6 transparency not being recognized by ArcMap (this is recognized in Global Mapper v16). The removal of the residual collar was accomplished by using the following procedure. 1) The Draw toolbar was used to create a polygon graphic that covered the extent of one topographic map - excluding the residual white borders. 2) This was converted to a shapefile using the "Convert Graphic to Feature" option from the Draw toolbar menu. It was necessary to open an Edit session to adjust the verticies of the polygon so that the first quad could successfully be clipped using the Clip (Raster) tool. 3) The Clip (Raster) tool was then used to clip each quad by the converted graphics. This was run for each of the 40 quads making up the Rhode Island. In each instance it was necessary to move the converted polygon graphics to a new location, and to adjust the verticies. This was all accomplished while an Edit session was in progress.
