Plane-table surveying is still taught by a few schools. Several camps prepare students for specific occupations by teaching hydrologic, engineering, mining, or geophysical techniques. Fieldwork incorporating GPS and GIS technology has become more common in the past few years. The choice of camp often depends upon time and money . Be sure that shorter camps satisfy your department's graduation requirement.
Cost is important but difficult to judge sometimes.
A few camps are cheaper because they are subsidized while several are more expensive because of high tuition costs. The academic intensity at field camp ranges from mild to pretty strong. At ISU we are in the field six days a week, mapping on five of these days and looking at regional geology on the sixth. Completed assignments are due every second or third day, so students do office work 2-4 hours each evening. This appears to be a bit more intense than most camps.
