Taking Technology in the Field: Data Collection and Mapping on a Tablet PC discusses using tablet computers for data collection in archaeology, ecology, and geoscience fieldwork. Tablet PCs allow archaeologists to directly document excavation sites and map grid squares. Ecologists use tablets to teach long-term ecological research and study the effects of invasive plants. Geoscientists employ tablets to teach geomorphological concepts, have students use new technology, and measure stream changes over time. Overall, the document examines how tablet computers facilitate field-based data collection and mapping across multiple scientific disciplines.
