3.1. Data use
Our study aims to test and use remote sensing to study the evolution and
the state of vegetation in the forest of Tenira. Completion of this work
will necessitate the availability of the series of satellite data dating
from August or September (data 1: 1987, data 2: 1992, data 3: 2002, data
4: 2007, data 5: 2010, data 6: 2013, data 7: 2015, data 8: 2018),
details on exploited landsat images are reported in table 1. Data were
downloaded from the USGS global visualization viewer glovis on-demand
interface (http://glovis.usgs.gov/). They allow us to appreciate the
vegetation cover perennials, constituted plant stability element of
landscape.
