LitoSite Android application was created to accommodate the needs of geologists in research in the field. In this application there is an online-offline system to anticipate an unstable internet network when conducting research in the field. There is a geological map along with filters for rock types and formations, strike and dip measurements, and local data logging that can be accessed by users without having to login to the application. With this application, it is hoped that LitoSite can be used for research in the field and help more geologists in research activities in the field.
