Abstract
The estimation of dendrometric parameters of tree crops is crucial to decision making support for ecological and economic reasons. However, traditional methods for its measurement are time-consuming and laborious. Remote sensing data acquired from unmanned aerial vehicles (UAVs) combined with computer vision and Structure from Motion (SfM) algorithms can provide an easier and reliable solution to estimate those parameters. Nevertheless, various UAV flight settings can influence the quality of parameters derived from these data (e.g., flight height, imagery overlap). Thus, the main goal of this study is to assess the impact of different flight configurations on the detection of olive trees and on height and crown diameter estimation. The results showed that not only the configuration of the flight affects the dendrometric results, but also the topography of the terrain. Automatic tree detection revealed to be insensitive to the different flight configurations, whereas the tree height estimation was strongly affected. Among the analysed flights, the plan in double grid at 60 m of flight altitude and 90% of frontal overlap showed the best performance.

Abstract
In the last decade Unmanned Aerial Systems (UAS) have become a reference tool for agriculture applications. The integration of multispectral sensors that can capture near infrared (NIR) and red edge spectral reflectance allows the creation of vegetation indices, which are fundamental for crop monitoring process. In this study, we propose a methodology to analyze the vegetative state of almond crops using multi-temporal data acquired by a multispectral sensor accoupled to an Unmanned Aerial Vehicle (UAV). The methodology implemented allowed individual tree parameters extraction, such as number of trees, tree height, and tree crown area. This also allowed the acquisition of Normalized Difference Vegetation Index (NDVI) information for each tree. The multi-temporal data showed significant variations in the vegetative state of almond crops.

Abstract
Material heritage typically has a whole set of associated immaterial heritage, which is essential to pass on to the visitor as a cultural mission of the destinations and those who manage them. In this sense, the interpretation of material heritage is a complex process that is not a fully efficient process with the mere observation of physical artifacts. In this context, it emerges as fundamental to provide visitors with a set of tools that allow them to correctly interpret the artifacts that come to fully understand the cultural dimension of the destinations and their heritage. Accordingly, the role of virtual reality can leverage the creation of innovative and immersive solutions that allow the visitor to understand and feel part of their own heritage and its ancestral component that defines the sociocultural roots of destinations and their civilizational traditions. This article, after dissecting and substantiating the role of virtual reality in the interpretation of heritage, presents a conceptual model, based on the use of virtual reality, which was, in part, prototyped in the scenario of the Portuguese Museum in the city of Miranda do Douro. This proposal is an ongoing contribution to the creation of innovative and immersive tools for the interpretation of heritage. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Abstract
The aim of this paper is to provide an analysis that will be necessary for the development of a future digital marketing plan for CubiCasa OY with the main goal to attract new customers in the United States market. Specifically, the following topics are addressed during the analysis: external and internal examination of CubiCasa in the United States market to assess the current company’s position in the market; performing empirical research to figure out the most important aspects for real estate photographers and businesses. It was followed a qualitative research method with semi-structured surveys sent by Google forms to eight customers who use floor plan creation tools and operate in the US. The findings will help to analyze and make an appropriate decision when adapting it to a digital marketing plan and help to improve customer reach and brand awareness among the United States floor plan makers and companies specializing in real estate business.

Abstract
The tourism sector has gained increasing importance in the economy of many regions, or even countries, however, the way in which organizations and territories communicate and promote each other, to attract tourists, significantly impacts the success of the sector, and digital marketing strategies have stood out as promising. Thus, in a digital society, in which information and communication technologies are present in the daily life of the general population, especially mobile technologies, it is essential that the tourism sector seeks innovative and differentiating marketing and communication strategies. When considering the technological advances, which have been asserted lately, wireless communication networks with high bandwidth, processing capacity of mobile technologies, Internet of Things, Big Data, Virtual and Augmented Reality, Empowered Smart Cities with different technology; it can be said that the conditions are in place so that new paradigms and marketing strategies can emerge. These technologies allow to communicate with the target audience in a more impactful way and stimulating different senses, that is, immersive. It is in this context that the opportunity and motivation for the development of this research work arises. In this sense, this work highlights the technologies that we consider most relevant, combining them in a conceptual model that is proposed and that we consider enhancing an immersive and innovative digital marketing strategy, for the promotion of touristic destinations.

Abstract
Smart cities are, by nature, spaces with a richness and diversity of technologies incorporated in their physical spaces, in such a way that they can be seen as a single intelligent and collaborative space. As technological pillars, two important layers arise – the sensory layer and the actuator layer, both of which are strongly interconnected with each other, emerging as a large Internet of Things network. This scenario reveals an enormous potential for marketing science and for the creation of innovative strategies to promote territories as touristic destinations. Within the multiple opportunities, there is space for the development of an interactive marketing experience, revolutionizing, through creative rethink, the way destinations interact with their visitors, and make known all their potential. Although in the context of tourism, there are three main moments in the visit process – the before, the during and the after, this work focuses on the moment of the destination visit – the during. In order to understand how creative rethink can be carried out to create innovative strategies to promote touristic destinations, an introduction is carried out, substantiating the concepts of digital marketing, smart cities and Internet of Things. Then, the methodology that governed the creation of a collaborative model for smart cities is clearly defined, being contextualized the importance of destinations-communication, the concept of a smart city and some of the major technology that support this concept. After contextualization and methodological aspects, this article presents a conceptual model where its components are described and where it is discussed how the model can take advantage of the variety of technologies that exist in a smart city, in order to allow innovative digital marketing strategies and innovating in the interaction between the city and the visitant, and vice versa – the vision of interactive digital marketing. In the model discussion, some interaction-scenarios and their main benefits are highlighted, which serve as examples for validating the proposed model. Finally, we present the work limitations and mains conclusions.
