While tablet devices are becoming commonplace in archaeological research, the transfer of data for analysis is a matter of critical concern. As geographic information systems (GIS) are increasingly incorporated into our archaeological research, there is a need not only to streamline data acquisition, but also to collect data that can be used in conjunction with high-level spatial analytical tools, such as those available in ESRI’s ArcGIS. During a short lab season, various methods of paper-free data collection and cross-platform transfer using these user-friendly devices were tested. It was found that both iPad and Android-based systems present great advantages in terms of portability and electronic data acquisition. However, file compatibility and transfer of data across multiple platforms present a number of important drawbacks. The present case study focuses on the development of a data collection protocol implemented by the Proyecto de Investigación Arqueológica Zaña Valley (PIAZ), Peru, that moves beyond these limitations. The ultimate incorporation of data collected using tablet devices demonstrates the potential for this tool in archaeological research, along with the pitfalls for projects that rely heavily on GIS. Significant findings regarding the advantages, as well as the limitations, of e-data collection, transfer, and storage are discussed.
