The Map Collection GIS Service burns data CD's for patrons free
Often, GIS data sets are derived from several different sources
in different formats and projections. The GIS Service will organize,
spatialy snycronize, and in some cases create and update metadata
for patrons. This data and metadata is then burned to a CD-Recordable
disk for the patron to use at various locations where ArcView and
associated GIS software may reside.
Important things to note about GIS data on CD-R disk is that data
can be added to it later if the disk is left open. Data cannot be
deleted from a CD-R (this ensures data integrity) like a CD-RW.
The GIS Service does not distribute data on CD-RW, floppy disks,
or zip disks. Patrons have the option of transferring their data
to these media once they have their CD-R. It is recommended that
patrons do transfer data to the above-mentioned portable media or
to a local hard drive or network space to make it easier to port
project files (.mxd in ArcGIS, .apr in ArcView 3x).
