Heritage landmarks and historical values often coexist with places and regions of remarkable environmental and landscape wealth. This article studies their capacity to generate global understanding of their territory through the creation of cultural routes. The proposed methodology is verified through the study of the defensive features of the ancient Nasrid Kingdom, the last Islamic territory in the Iberian Peninsula from the thirteenth to the fifteenth century, which shaped the Spanish region known as the Kingdom of Granada until the nineteenth century.

To assist in the proposal of new routes, a precise collection of physical data (topography, landmarks, resources, population centres …), existing public paths and protected natural sites was carried out. Those cultural routes relevant to the area of study were also selected and mapped through GIS. A set of indicators prioritised through an analytic hierarchy process (AHP) have evaluated the proposed itineraries.

The methodology enables the integral evaluation of parameters such as natural heritage, existing paths networks, defensive architectural heritage (watchtowers), existing cultural routes or proximity to basic services. The methodology's application allows an index to be obtained that quantifies the global implications of these parameters in the design of new itineraries. This leads to the development of a network with its own narrative that provides a historical, environmental and cultural meaning.

Watchtowers in this region have previously been studied as isolated and locally relevant architectural features. This work studies them from an overall perspective, considering each tower as a piece of a complex defensive and territorial system. Cultural routes arise from this joint interpretation as tools to restore and highlight the interrelationship between architectural heritage and territory and people.

Growing awareness of the importance of preserving the built environment has created an increasing demand for experts capable of performing building inspections to ensure a high level of preservation. Technical surveys include a set of procedures and tests that have become essential tools providing the necessary knowledge required for maintenance, preservation and improvement of buildings. The paper aims to discuss these issues.

Within this set of inspection techniques, this paper presents a method developed to produce vertical deformation plans from the levelling data obtained from different floors of a building. It also explains how to perform accurate levelling and an outcome analysis to provide displacement maps. Thus, based upon obtained measurements, it is possible to achieve 2D contour maps and three-dimensional (3D) surface mapping by means of specialized software that is typically used for cartographic and territorial analysis.

The developed methodology provides easier analysis of the deformation of buildings and structures. Consequently, the method produces relatively accurate outcomes that are sufficient to make a proper assessment that facilitates the diagnostic and decision-making process. The case studies analysed show the applicability and usefulness of the procedure.

This sustainable and non-destructive system is an essential instrument for providing valuable and useful information to the specialist. The 2D/3D graphical data displays enable easier analysis of survey results, also aiding comprehension of these results in the context of liability claims.
