I am still old fashioned, using my field book to take notes and sketch outcrop figures, then use MapInfo with the Discover add-in as a GIS program, exporting it to CorelDraw for the final figures. But that is not what I am getting at. Recently (Jan 2010), Cees Passchier and Ulrike Exner published a paper in the Journal of the Geological Society of India (vol. 75, issue 1) where they discuss all digital field notes and map-making using a Trimble field computer. The following is an excerpt from the paper where they talk about the software: "The software we use to monitor data in the process of normal mapping with a standard GPS with a resolution of 5-10m is Discover Mobile™ from the company Encom™, a program that is cloned on Pitney Bowes-MapInfo™. Discover Mobile™ is actually a simplified, pocket PC version of MapInfo, but adapted for geologists with added features such as geological symbols, and the possibility to enter measurement data of geological structures, well data, cross-sections etc." Though I am not yet as digital as the authors, I found it quite interesting to read, and it has its merits: Field notes, sketches (albeit digital), measurements and photographs are all cross-connected with a geological map. As I am currently leaving through 10 years old field notes, I have to admit, much to my shame, that not all data of every entry is unequivocal, e.g. some information got lost in time and space.... I recommend to have a look at the paper, it can be downloaded from the journal's website, if not, send me a message. http://www.springerlink.com/content/0016-7622/75/1/ All the best, Jochen *************************************************************************** Dr. Jochen Mezger Lehrbeauftragter - Lecturer Allgemeine Geologie Martin-Luther-Universität Halle-Wittenberg Tel.: 49-0-345-5526120 Institut für Geowissenschaften Fax: 49-0-345-5527220 Von-Seckendorff-Platz 3 06120 Halle Email: [log in to unmask] GERMANY http://www.geologie.uni-halle.de/igw/allgeo/staff/mez.html http://allgeo.geologie.uni-halle.de/mitarbeiter/jmezger/ ============================================================
