Digital processing of satellite imagery for search and classification of craters in the South Zone of Honduras

Abstract

This research aims to contribute to the creation and implementation of a methodology with remote sensing techniques to identify geomorphological features of craters, their study area was the south of Honduras as a method using the digital image analysis with the LandSat satellite TM and spectral signature capture in the field, with an ASD radiometer visible-infrared range. In the first phase, results collection consisted of rocky material, firm land cover spectral calibration of the images. In the second phase, we analyzed the spectral signatures, finding that the materials from the proposed sites as craters correspond to volcanic material, so the formations correspond to volcanic craters, ruling out the possibility of finding in this area specific meteoric origin thereof. Both filters as main components generated to find hydrothermal alterations were to determine priority areas of craters and radiometry to establish the type of material present and characteristic of either Crater (volcanic or meteoric).
