In many fields today, it is necessary that a team has to do operational planning for a precise geographical location. Examples for this are staff work, the preparation of surveillance tasks at major events or state visits and sensor deployment planning for military and civil reconnaissance. For these purposes, Fraunhofer IOSB is developing the Digital Map Table (DigLT). When making important decisions, it is often helpful or even necessary to assess a situation on site. An augmented reality (AR) solution could be useful for this assessment. For the visualization of markers at specific geographical coordinates in augmented reality, a smartphone has to be aware of its position relative to the world. It is using the sensor data of the camera and inertial measurement unit (IMU) for AR while determining its absolute location and direction with the Global Navigation Satellite System (GNSS) and its magnetic compass. To validate the positional accuracy of AR markers, we investigated the current state of the art and existing solutions. A prototype application has been developed and connected to the DigLT. With this application, it is possible to place markers at geographical coordinates that will show up at the correct location in augmented reality at anyplace in the world. Additionally, a function was implemented that lets the user select a point from the environment in augmented reality, whose geographical coordinates are sent to the DigLT. The accuracy and practicality of the placement of markers were examined using geodetic reference points. As a result, we can conclude that it is possible to mark larger objects like a car or a house, but the accuracy mainly depends on the internal compass, which causes a rotational error that increases with the distance to the target.

One of historical learning goal in Indonesia is to instill knowledge of historical facts and insights concerning past events, and character attitudes and values. It will produce quality outputs that include understanding the historical event, imitating the wisdom, and the wisdom of the historical offender. Therefore, the improving of the cognitive ability requires easy, cheap, interesting and interactive learning media is needed to improve the ability of historical explanation in accordance to the development of Information Communication and Technology (ICT). Learning media in accordance to historical material is needed to be applied in the historical learning digital-based. This research was conducted in SMA Negeri 5 Surakarta with the research subject of class XI MIPA 1 research which 32 people. This research is an experimental research. The data collection used a digital assessment questionnaire and an instrument with 10 questions to measure the increase in historical explanations. This study aims to see the application of digital-based maps to improve the ability of historical explanation. The research result shows that there is an increase in the ability of historical explanation by using digital maps.

How we elicit rich reflections from people about their feelings and experiences is a central consideration of qualitative research. Creative techniques of elicitation can open reflective dialogic spaces between participants and researchers, bridging memory and meaning. In this article we discuss participant-led explorations of a digital story-mapping platform as an elicitation technique in qualitative interviews. This platform is Queering the Map, a community-generated counter-mapping project that digitally archives queer moments in place. An atemporal cartographic representation of queer life, visitors to the site zoom, drag and click to reveal the anonymous contributions of others: micro-stories of experience, poems, messages and yearnings, claiming a global landscape of queer feeling. Here we offer reflections from our experience of asking participants to explore and guide us around the map within an interview. We chart how this method of live digital discovery was generative of elicitation and evocation, of insights on affective roots (where have I come from?) and affective routes (where can I take you?). This article contributes to scholarship on elicitation and live methods, including digital and spatial approaches, and to conceptualisations of orientation and mapping.

Purpose: The purpose of this paper is to analyse the potential of literary tourism in Portugal and explore the advantages of creating a digital literary map about the places associated with the widely renowned Portuguese author Fernando Pessoa (hereafter Pessoa), as well as the places that he suggests in one of his works, a tourist guide of Lisbon: What the Tourist Should See (1925).

Methods: Firstly, a study of the state of art of the key concepts was made in order to apply them in the second part, the methodology, in the case of studying Lisbon from Pessoa's perspective. Then, allying personal taste for the writer/author with interest in cultural promotion gave rise to a digital literary map of Pessoa's Lisbon. Methodologically, a questionnaire was applied covering a sample of 173 valid literary tourists.

Results: literary tourism should be an object of in-depth studies, as it tends to be beneficial for cultural promotion of tourist destinations and products, specifically for literary tourists. Further limitations, implications and future suggestions of this study are provided.

Implications: This paper is the first to empirically test literary tourism, proposing a digital literary tourism map. Regarding the main findings, there is high interest from literary tourists in exploring the literary places associated with Pessoa, physically or digitally.

This paper reports a study into the formalization of algorithms for solving problems, the generation of data for digital maps, as well as their implementation, through a set of simple operations that would be intuitively clear to a user who is not a specialist in the field of geoinformation technologies. The approach that has been proposed is based on the construction of typical scenarios for model execution. Such scenarios are edited and adapted to the use of alternative electronic terrain maps. The result of scenario operation is a set of data ‒ layers of a digital map based on the input parameters for the model and the problem-solving algorithms, compiled by an expert. That makes it possible to construct libraries of typical scenarios, to store them centralized, as well as provide a common access to the scenarios, and to exchange data among applications. The result of running a scenario is that the user is provided with a possibility, without writing a programming code, to perform complex operations on processing geographical data and to simulate various processes at an electronic terrain map. A geospatial analysis expert system has been developed, containing both the basic functions for geographical data processing and the high-level specialized models. A tree of decisions is built under a mode of visual construction of a problem-solving algorithm. We have implemented a conveyor of operations at which the data sources in an expert system derived when performing any operation are sent to the input of the next operation. The results of this research could be used in simulation models of military activities, the tasks on photogrammetry in designing the optimal routes to fly over a territory, and as an additional tool for analysis of terrain in geoinformation systems. There is a possibility to expand the functionality of an expert system and to add new types of operations. Thus, there is reason to assert that the process of automatic construction of data for digital maps requires specialized software and highly ...

POVOAR is a not-for-profit association whose main goal is to explore, improve and decentralize the artistic and cultural sector in countries where the latter is underestimated, unequal and underdeveloped. POVOAR came to light with the concern of the centralized and neglective systems that rule many countries and limit the flourishing and diversification of the cultural and artistic fields. As a response to such issues, a pilot project was created based on the mapping of artistic and cultural expressions over the regions of Portugal. The country was chosen to initiate the project as it represents a good example of a culturally rich but poorly invested territory. The first steps of the project rely on an on-site campaign of data gathering of the cultural and artistic expressions of one of the poorest regions of the country: Beja. The findings of the research then become available on an online platform, through a digital map accessible to anyone. In the long-term, the association intends to expand its research to other countries by pairing projects and relating people and activities from different communities, based on their similarities, with the aim of creating a worldwide cultural network. At the core of POVOAR there is a quest for connections: human, artistic, heritage, and geographical relations drive us towards the future, and have been driving us to where we are today. The project was born from a shared interest in human encounters, a passion for tales of tradition, and a need for preserving what is getting forgotten in every community. POVOAR has the power to bring visibility and opportunities to the people of the cultural sector, raise awareness of the importance of arts and culture, encourage an alternative form of tourism - more committed and sustainable - and provide the governments with a database of diversified useful information to develop truly effective cultural policies. ; info:eu-repo/semantics/publishedVersion

The field of cartography, as the study of the history and meaning of maps is in decline. It is being ingested into what might, on the surface, seem like a continuation of the discipline but in fact is not. I'm referring here to the practices of digital modelling. I'm not by any means bemoaning this loss. Contrary to what one might imagine, the map is a relatively recent practice dating back only to the 1500. Its lineage coincides with the emergence of the disciplinary sovereignty and state power, what Archille Mbembe might call necro-political power. The map in that sense is a descriptive performance of state territory. Without a map, the state would not be conceived of as a thing, a map-able object with borders and edges. State borders are brought into being through mapping. The map becomes the icon or as Benedict Anderson claims the logo of the nation state and this icon with its definite borders erases the lineage of its construction. What I'm proposing here is that it is not that the map was transformed into a digital map but rather that digital modelling as a practice cannibalised the remnants of a dying tradition for its own gains. It saw how effective mapping had been to extend sovereign power, its territory and sought to utilise it. It is cartography that gets subsumed into the emergent field of spatial analysis. However, with modelling the extension of power is no longer bound to the land. Therefore, the trajectory of the move from mapping to global information systems (hereafter GIS) is not a linear progression but rather a disruption and displacement of the map by the model. In fact, most applications that later become the digital map didn't have a map to begin with. They were created in order to forecast population information for the user by city officials, planners and businesses. The so-called maps, such as the OXAV and SYMAP were complex and had their own symbols with an accompanied user manual that explains how they were to be interpreted. None had a drawing of the terrain or land. I want to question the role of digital modelling more generally. Digital Modelling is pervasive in most of what might be defined as the digital, from CGI, 3D modelling, models of high frequency speculative trading algorithms, Google's Baysian search term suggestions all the way to machine learning and neural networks. But just like the map the model erases traces of its lineage so it's important to unearth them.
