The work presented aims to show which methodology has been used for the creation and representation of the uses and covers of the land in two different periods of time (1956 and 2013) in the region of Bidasoa, in País Vasco, and how we can develop an analysis related to the ecology of the landscape with the results taken from the fulfillment of this methodology. To carry out this methodology, we have had to acquire the images belonging to the American flight of the year 1956, orthorectify and position them in the space by means of the ERDAS Imagine 9.1 software. Then, we have had to digitize and photointerpret the uses and covers of the land related to the orthorectified image of 1956 and the current image of 2013. This process was performed by means of the eCognition software in order to obtain, in the end, images in raster format using the ArcGIS 10.1 software. With these final images, we were able to carry out an analysis of the ecology of the landscape through FRAGSTAT, which analyzes spatial patterns in order to quantify the landscape structure. The results obtained from the methodology are the two maps in raster format. These maps are the basis for drawing the results related to the indices of the landscape. The first results show us how the methodology used to create the maps of the uses and covers of the land is really innovative because of its speed of execution and effectiveness. It is also detected how the landscape has evolved to a greater heterogeneity nowadays and how it has become into a more fragmented landscape although with more diversity. Finally, humanized process is clearly seen in the overall structure of the landscape where the human activity has a key role ​
