    All,

    Based on USGS's latest updates to the 3DHP Specifications documents Sue described above, and the additional of the new 3DHP Guideline Resources documents Silvia presented to the 3DHP Info Forum earlier this week, I've updated/added all of these resources to the NSGIC 3DHP Information HUB page [HERE].
