It contains twenty prints with "plans des chateaux de Naples et des villes de Gaette, Pescare, Longone, Talamone et Orbitelle", and local cartography. It is a magnificent example of the way in which territory was represented prior to the developments made as a result of Geodesy and Cartography. Firstly, we place the manuscript in its historical context: the reign of Philip V, at the outbreak of the War of Spanish Succession (1702-1714). Next, we refer to the cartography practised by then and, finally, we analyse the graphical procedures that the cartographer used to represent the terrain, topography, the architecture, and the fortifications and the city.

Para ello se han caracterizado los diferentes símbolos cartográficos que aparecen en los mapas, que constituyen los parámetros de referencia del análisis y transmiten información fidedigna de la forma y significado de lo representado. Para esas tipologías se han encontrado ciento trece símbolos diferentes, lo que da idea de la minuciosidad y riqueza de la información contenida en los mapas. Dieciocho de ellos, son equivalentes con otros tantos símbolos cartográficos de Chevalier, maestro de D'Anville, de quien Tomás López fue discípulo en París. También hay una similitud entre cuatro símbolos del AGE con sus correspondientes signos de las Ordenanzas del Real Cuerpo de Ingenieros de 1803.

The demonstrated property consists of which the logarithmic spiral is a autoisoptic curve, that is to say that if from a point P anyone of the spiral tangent straight lines draw up to the previous arc, these form a constant angle α. This demonstration is novel and in addition we get to contribute a method to calculate the angle α given the equation of the spiral.

Historical cartography should be evaluated in terms of precision and uncertainty prior to their use in any application. In the last decade, the majority of papers that address multi-objective optimization employed the concept of Pareto optimality. The goal of Pareto-based multi-objective strategies is to generate a front (set) of nondominated solutions as an approximation to the true Pareto-optimal front. This article proposes a solution for the problems of multi-objective accuracy and uncertainty analysis of pre-geodetic maps using four Pareto-based multi-objective evolutionary algorithms: HVSEA, NSGAII, SPEAII and msPESA. ''The Geographic Atlas of Spain (AGE)'' by Tomas Lopez in 1804 provides the cartography for this study. The results obtained from the data collected from the kingdoms of Extremadura and Aragon, sheets of maps (54-55-56-57) and (70-71-72-73), respectively, demonstrate the advantages of these multi-objective approaches compared with classical methods. The results show that the removal of 8% of the towns it is possible to obtain improvements of approximately 30% for HVSEA, msPESA and NSGAII. The comparison of these algorithms indicates that the majority of nondominated solutions obtained by NSGAII dominate the solutions obtained by msPESA and HVSEA; however, msPESA and HVSEA obtain acceptable extreme solutions in some instances. The Pareto fronts based on multiobjective evolutionary algorithms (MOEAs) are a better alternative when the uncertainty of map analyzed is high or unknown. Consequently, Pareto-based multi-objective evolutionary algorithms establish new perspectives for analyzing the positional accuracy and uncertainty of maps.

However, historical data often exhibit heterogeneous quality. In calculating the transformation parameters between the historical and modern maps, it is often necessary to discard highly uncertain data. An optimal balance between the objectives of minimising the transformation error and eliminating as few points as possible can be achieved by generating a Pareto front of solutions using evolutionary genetic algorithms. The aim of this paper is to assess the performance of evolutionary algorithms in determining the accuracy of historical maps in regard to modern cartography. When applied to the 1787 Tomas Lopez map, the use of evolutionary algorithms reduces the linear error by 40% while eliminating only 2% of the data points. The main conclusion of this paper is that evolutionary algorithms provide a promising alternative for the transformation of historical map coordinates and determining the accuracy of historical maps in regard to modern cartography, particularly when the positional quality of the data points used cannot be assured.
