Surveying involves exploring the area you wish to map, hunting down survey points and collecting data to increase the quality of your survey, which will increase the quality of the map you eventually create. This is main way to gain cartography XP, and is how you improve a map's quality. Each successful survey adds to the quality a little bit, depending on the quality of your dioptra and your skill level. You need at least four successful surveys to convert your incomplete survey to a complete survey that can be used to paint a map.
