| Sumario: | During the last 25 years. significant geomorphological changes have been detected in the coastiline of Punta
Zacatal and the western region of isla del Carmen, Campeche, as consequence of the current littoral dynamics and
the influence of urban and industrial development.
In order to detect such changes, a color overlay and composition image analysis was carried out using three Landsat
MSS satellite images dated 1974, 1986 and 1992. A near-infrared band (0.8-I.l!~m) was applied to each primary
color; assigning color ta high-reflectance values showing changes in land distribution. And absence of color to water
bodies and land that remained unchanged. The color presence/absence relationship for each mage allowed to detect
coastal accretion, erosion and stable areas in a false-color composite. Aflerwards a supervised classification was
canducted to obtain areas and percentages, which were verified by means of multi-temporal photointerpretation and
GPS fielidwork validation. |
