VibeAgent blends Map mashups, social networking and travel

November 24, 2007 by gisuser

I read about this one in the USA Today… a new travel mashup that incorporates a little social networking enabling users to setup a more web20-ish profile, save trips, search for travel related info, join groups etc… I’m still fumbling around but so far it’s quite clever. See www.vibeagent.com

I wish I could save past trips and include handy info about the trip.. hotel details, restaurant info etc… for example, I wish I could recall the name of that great Thai place in San Fran I ate at or the Indian join in San Jose… maybe that will come next. I do like the reviews and the ask an agent feature is cool!

USGS land/sea mask dataset

November 24, 2007 by gisuser

An excellent free, Global data resource… The land/sea mask has been improved and now includes ocean boundaries from the World Vector Shoreline (WVS) data set. The boundaries for U.S. Great Lakes and St. Lawrence seaway come from the Political/Ocean (ponet) layer of the Digital Chart of the World (DCW). The boundaries of inland water bodies come from the perennial water bodies and polygon features (double line rivers) of the Drainage Network (dnnet) layer of the DCW. The land/sea mask has been generalized during the process of rasterizing the vector data to 1-km grid cells. A 1-km cell is assigned to land or water based on the dominant area of a cell. World Vector Shoreline boundaries have precedence over DCW. Grab it at http://edc2.usgs.gov/1KM/land_sea_mask.php
