Abstract
In this work a study has been carried out in order to estimate population on a strip of land of 100 km length and 50 km width, placed in the Eastern part of Spain. We have made use of a SIR‐A image obtained from the Columbia shuttle on November 1981 and referred to the mentioned area.
It is shown the difficulty of estimating population in coast nuclei due to the large number of touristic buildings which deceive the population census. Nuclei with less than 2000 people may be identified in many cases but it is hardly difficult to estimate their surface.
With the remaining nuclei we have carried out a twofold classification according to the number of people. The surface of semi‐urban nuclei, of less than 10,000 people show a dependency with the number of people between three and four times below to that of urban nuclei of more than 20,000 people.
