What conditions must surveys be conducted under?

Favorable weather is needed for accurate measurements and safe field work. Clear weather provides good visibility, stable line-of-sight for prisms and targets, and minimizes atmospheric distortions that can skew readings from instruments like total stations or levels. When conditions are rainy, foggy, or windy, readings become less reliable, instruments can be difficult to set up and maintain, and safety risks increase. The other options don’t guarantee reliable results or safety, whereas clear weather directly supports precise surveying work, making it the best choice.
