Another treat for those bringing their devices on the trip -- there's no requirement to bring one -- will be access to a collection of GIS data sets from the Instituto Geológico y Minero de España (IGME / Geological and Mining Institute of Spain). IGME provides free access to a wide variety of geologic and thematic data, and we've selected and customized a useful subset for the trip participants. They will be able to use GPS to find themselves on geologic maps, click to identify geologic features, pan/zoom/search to view the data from different perspectives, and combine different layers with transparency. (For more details, see the geopad.org post, Electronic Reference Materials on Field Trips: ArcGIS and iGIS Apps.)
