Control of locating equipment used by a locate technician to perform a locate and/or marking operation to detect and/or mark a presence or an absence of at least one underground facility at a work site is based at least in part on marking specifications (e.g., government-based regulations, industry-based recommended guidelines/best practices, standard operating procedures of locate companies and/or facility owners, and/or contractual obligations relating to marking operations). In various examples, control signals are generated to alert a locate technician when to start and stop dispensing of a marking material, or control signals are generated to automatically or semi-automatically control dispensing of the marking material by a marking device, so as to facilitate compliance with marking specifications.
