Measuring height using a portable device Quality assurance

Based on EHES Manual, Part B. Fieldwork Procedures, 2nd edition (2016) Available at: http://urn.fi/URN:ISBN:978-952-302-701-5 These slides can be used freely, translated and adapted to national use (e.g. concerning the equipment and fieldwork organization). However, it is important to keep in mind that no changes should be made to the measurement techniques, which need to be standardized.
