Data manipulation and storage
There are public workstations in the Geospatial Centre that provide access to ArcGIS and software programs, program extensions and data manipulation utilities. Patrons may use the Geographic Information System (GIS) and image processing software in the library to view and manipulate the data. UWaterloo faculty, students and staff may copy these data to other media for use elsewhere.
These images may be exported from ArcGIS in a choice of bitmapped formats (also known as raster graphics) including JPG, TIFF, GIF, and BMP or in a choice of vector graphics formats including Adobe Illustrator (AI), Encapsulated Postscript (EPS), and Scalable Vector Graphics (SVG). Yet another option is PDF. The user defines the output resolution.
