Representing coastal land use in the island of Gran Canaria

Abstract

This map displays a geographic information system-based spatial analysis representing coastal land use in the island of Gran Canaria. It presents a method of summarizing coastal patterns of land use/cover into arc/sectors of a graph, setting up spatial units of analysis based on compass directions suitable to organize, analyse and depict spatial data. The method allows the easy detection of patterns and visualization of similarities between two or more sets of coastal land use/cover data. This paper outlines the methods used in designing the map.

The Land-Use Change Dynamics Based on the CORINE Data in the Period 1990–2018 in the European Archipelagos of the Macaronesia Region: Azores, Canary Islands, and Madeira

“…On the contrary, and as in 1990, there were several land-uses whose ENN values are the lowest and equal. The value is as before- 60 Each of the soil-uses previously classified according to the CLC nomenclature for level 3 are quantified in class metrics. In the case of the shape index, the arithmetic mean was determined.…”

“…For example, the Laurisilva of Madeira is the largest surviving relict of a virtually extinct laurel forest type, once widespread in Europe. It is still 90% primary forest and is a center of plant diversity, containing a unique suite of rare and relict plants and animals, especially endemic bryophytes, ferns, vascular plants, and animals, the Madeiran long-toed pigeon, and a vibrant invertebrate fauna [59,60].…”

The laurisilva habitat has been reduced to small disconnected pockets.…”

“…The multiple-static-maps strategy suits particularly well LULC assessments, because each graphic presents a snapshot for a discrete period. Thus, if two or more graphics are juxtaposed, the reader can visually compare LULC data (Rodrigues, 2016). As shown in Figure 1, this method allows inferring trends over time, including LULC gains and losses.…”

“…As researchers have an increasing amount of LULC data, there is a continuous need for tools and methods to synthesize information (Rodrigues, 2016). On this matter, a dominant approach relies in coupling geographic information science (GIS) techniques, with the use of geo-visualization, to accelerate the process of visual geospatial exploration (Gugl, 2009).…”
