Short course on Cartometric Analysis and Numerical Modelling (Feb 16 - Apr 27) by Joaquim Alves Gaspar

February 2, 2018

The aim of this short course is to introduce the cartometric methods of geometrical analysis and numerical modelling applicable to the study of old charts and maps. Although it is primarily meant for the MEDEA-CHART research team, all professors, researchers and students are welcome to attend. Lectures will be in English.


Six sessions of 90 minutes are initially scheduled for February 16 and 23 February, and March 2, 9, 16 and 23, at 10.30h, room 6.2.52 ( except the dates 6, 13, 20, 27 April - room 8.2.14) of the Faculty of Sciences, University of Lisbon. Additional sessions may be scheduled in the future. The main objective of project Medea-Chart (financed by the European Research Council) is to solve a series of crucial questions related to the origin, technical evolution and use of nautical charts during the Middle Ages and Early modern period.
