A few extra readings on PPGIS, VGI and data sharing

After some presentations this week, I have gotten requests for more information than I was able to cover.  So here are three free and online papers that I humbly offer to continue that conversation:

• Tulloch and Shapiro on Access and Participation
• Tulloch and Harvey on Data Sharing Practices
• Tulloch on PPGIS in First Monday

So far, the audiences for these talks have been incredible.  And I hope to share a little more about this over the next few days.

Stay tuned...
