We compare the Algarve maps resulting by each one of these representations when the origin of coordinates is moved from the center of mainland Portugal (that is in force) to the center of the Algarve. For the LCC map projection, the analysis takes also into account the change of the upper parallel from the North of Portugal to a latitude inside the Algarve border. The area and perimeter of the Algarve is computed and the location of its geographic center is determined in every map representation. Borders lengths that separates the Algarve from Alentejo and from Spain, and the extents of its South and West coasts, are also computed. We conclude by presenting the map, the values of area and perimeter and the location of the geographic center that should be considered for the Algarve, at different scales and for the available data.<\/jats:p>","DOI":"10.1051\/fopen\/2019022","type":"journal-article","created":{"date-parts":[[2019,7,18]],"date-time":"2019-07-18T07:51:32Z","timestamp":1563436292000},"page":"27","source":"Crossref","is-referenced-by-count":0,"title":["Map production and data analysis with local parameters"],"prefix":"10.1051","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9053-8442","authenticated-orcid":false,"given":"Hermenegildo Borges","family":"de Oliveira","sequence":"first","affiliation":[]},{"given":"Fernando","family":"Granja-Martins","sequence":"additional","affiliation":[]},{"given":"Helena Maria","family":"Fernandez","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2019,7,18]]},"reference":[{"key":"R1","unstructured":"SYA (2015), Statistical yearbook of Algarve region 2015, Ed.: Instituto Nacional de Estat\u00edstica, Lisbon, Portugal (2016).
