This blog posting presents an alternative method for transforming USGS Topographic maps from the GeoPDF format into a more GIS-friendly format - the GeoTIFF. Here, we will introduce GDAL, an open-source software program that has been specifically designed for use in reading and writing information to geospatial raster data formats.
Advancing Geospatial Solutions for Environmental Challenges
The Environmental Data Center is the center of technical expertise in GIS for the state of Rhode Island. The (EDC) is a Geographic Information System (GIS) and spatial data analysis laboratory in the University of Rhode Island's Department of Natural Resources Science, College of the Environment and Life Science. Major areas of research at the EDC are spatial data modeling, ecological mapping, and data integration for environmental applications.
The mission of the EDC is to support the use of contemporary tools of spatial data processing and electronic dissemination in the analysis and distribution of environmental data. This is achieved through collaborative research with faculty in the Department of Natural Resources Science and projects with agencies external to URI.

The Field Calculator provides GIS users with a powerful way to efficiently edit attribute table field values. It helps to eliminate tedious manual edits through the use of VBA Script Functions and Python Functions. This blog posting will explore some of the common VB Script string functions that can be used in the Field Calculator.
