This document contains two tables summarizing information about land resource surveys and naming conventions for coarse rock fragments. The first table describes different types of land resource surveys based on their scale and typical mapping unit sizes used for various planning purposes. The second table provides names and size groupings for coarse rock fragments over 0.2 cm in diameter. The document was compiled by Helmut Todotuasimamora from materials studied during his major in Natural Resource Management at Padjadjaran University in Bandung, Indonesia.
