Resumen

FLOREZ-YEPES, Gloria Yaneth; RINCON-SANTAMARIA, Alejandro; CARDONA, Pablo Santiago  y  ALZATE-ALVAREZ, Angela María. Multitemporal analysis of the vegetation cover in the area of influence of the mines located in the high part of Maltería in Manizales, Colombia. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.201, pp.95-101. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n201.55759.

One of the methods used to analyze environmental impacts occurred over time, is to know the evolution of ecosystems using Geographic Information Systems-GIS; so in this article, it is presented a multitemporal analysis of an area with influence of two production systems mainly: livestock and mining, and on which there are significant environmental impacts. The methodology was based on the use and digitalization of aerial photographs of the years 1998 and 2010 and an image taken of Google Earth of the year 2015 properly georeferenced, was worked with a scale 1: 25000; Also, the ArcGIS program was used for information processing. The analysis established the variations in plant cover over time, the influence of productive systems on forested areas, areas that have had recovery processes and others that have disappeared over time.

Palabras clave : Multitemporal analysis; mining zone; livestock production system; environmental impact.
