Abstract :
Despite the hazards, the population within
active volcanic areas has been increasing. Urbanization
in these areas result to changes in land cover and
increase of communities at risk. Thus, an accurate
understanding of land cover in volcanic areas is
necessary. Satellite remote sensing and geographic
information systems have been used for land cover
mapping for resources and land use planning. However,
there are not so much studies concentrating on volcanic
areas, especially in the developing countries. High
quality reference data also contribute to better
classification. This study seeks to map the land cover of
Taal volcanic area in Batangas province, Philippines. It
is one of the Twelve Decade Volcanoes of the world
having a reputation for being dangerous and worthy of
study, and where the tourism industry has been
progressing. LANDSAT 8 Operational Land
Imager/Thermal Infrared Sensor 2016 satellite image
and ground truth photos were utilized for the analysis.
The International Geosphere-Biosphere Programme
system was used to categorize the land cover types. The
Maximum Likelihood Classification algorithm was
facilitated for the classification and accuracies were also
calculated. The percentage of land cover classes will be
presented, focusing on the urban or built up areas and
its proximity to the hazard zones of the volcano.
