The photo survey service system of the invention comprises an image information receiving meansfor receiving image information from customer's terminal equipmentvia a telecommunication circuit network, which image information is obtained by taking photographs of an areaunder survey having a plurality of stations-n from a plurality of points using a digital cameraat a fixed focal length, an analysis processing meanswhich uses computation processing to calculate a three-dimensional vector relation of each station from the received image information on the basis of a difference in parallax between both images of adjacent photographing points, and an analytical result transmitting meansfor transmitting information on the calculated three-dimensional vector relation of each station to the customer's terminal equipmentvia the telecommunication circuit network
