Conclusion
A GPS unit is an economical way for libraries to collect data or lend to students to collect data
Can offer data of ‘teaching’ or ‘classroom’ qualityLower end units cannot support ‘research’ quality I have questions about libraries’ role to act as a
repository of crowd sourced data. I have a question about whether it is a Librarian’s
role to proactively create geospatial dataIt does provide access to a useful mobile
technology that will support the universities teaching mission
