A scoping review on the use, processing and fusion of geographic data in virtual assistants
(2021) Achig Balarezo, Rosario
Virtual assistants are a growing area of research in academia and industry, with an impact on people’s daily lives. Many disciplines in science are moving towards the incorporation of intelligent virtual assistants in multiple scenarios and application domains, and GIScience is not external to this trend since they may be connected to intelligent spatial decision support systems. This article presents a scoping review to indicate relevant literature pertinent to intelligent virtual assistants and their usage of geospatial information and technologies. In particular, the study was designed to find critical aspects of GIScience and how to contribute to the development of virtual assistants. Moreover, this work explores the most prominent research lines as well as relevant technologies/platforms to determine the main challenges and current limitations regarding the use and implementation of virtual assistants in geospatial-related fields. As a result, this review shows the current state of geospatial applications regarding the use of intelligent virtual assistants, as well as revealing gaps and limitations in the use of spatial methods, standards, and resources available in spatial data infrastructures to develop intelligent decision systems based on virtual assistants for a wide array of application domains.

(IEEE, 2023) Pacurucu Cáceres, Natalia Elizabeth; Bustamante Ávila, Juan Francisco; Morocho Zurita, Carlos Villie; Achig Balarezo, Rosario; Vivanco Cruz, Lorena Regina
Territorial planning plans are the result of the search for primary and secondary information sources with the knowledge of the technical team in charge of preparing or updating them, and ideally using the citizen's knowledge of the territory. To this end, various forms of citizen participation have been explored without much success. In the case study of this article, the Territorial Plan of the Cuenca Municipality, updated until 2022, has been analyzed, where the main result has been the lack of citizen participation. This article proposes a framework that describes the steps of organization, systematization and analysis of geographic information sources for Cuenca, where the large amount of existing but little used information is identified and that motivates the creation of a Virtual Assistant (VA) with specialized training according to the territorial planning axes defined for this municipality. This assistant must work on a platform for the integration and interoperability of geospatial information and existing geoservices, which is the SDI UCuenca.
Implantación de una aplicación móvil para PPGIS destinada a deslizamientos e integrada a una IDE
(2018) Santander Jaramillo, Darwin Fabián; Pacurucu Cáceres, Natalia Elizabeth; Achig Balarezo, Rosario; Morocho Zurita, Carlos Villie
A mobile application for citizen participation applied to Geographic Information Systems –GIS- has been created so that population can provide specific data on areas with landslides or susceptible to this phenomenon. With this information, researchers or decision makers can have updated and geo-located data from these areas. Based on information provided by the Secretariat of Risk Management -SGR- and the experience of the project staff, the profiles and contents of the survey implemented through the mobile application were defined. Later this application was used to get information in certain areas of the city of Cuenca in which studies of landslides were performed. The results of the information obtained can be visualized in the Spatial Data Infrastructure platform of the University of Cuenca –Ucuenca SDI-, in different formats. Additionally, the content of the mobile application was validated by the staff of the SGR.
Implementation of a basic risk guide for interactive digital terrestrial television using learning objects
(Springer Nature, 2021) Morocho Zurita, Carlos Villie; Cárdenas, Paola; Illescas Peña, Lourdes Eugenia; Maza Cordova, Jorge; Achig Balarezo, Rosario
The application “Disaster Risk Management Guide” for interactive Digital Terrestrial Television (iDTT), has been implemented based on the design that considers Learning Objects (LO) adapted to iDTT, where the receiving medium is the television and the main element of interaction is the remote control. The contents were worked on in coordination with the National Service for Risk and Emergency Management (SNGRE by its acronym in Spanish) of Ecuador, an organization that was also in charge of the validation. The implementation process, tests and improvements of the application are detailed, which includes three Learning Objects (LO) and a section with geographic information on emergency alerts in real time, obtained from a map server. Each LO addresses informational and educational topics, as well as a self-assessment for the viewer. The methodology for software development has been incremental, based on constant deliveries and progressive advances. The application has been developed in the Ginga NCL (Nested Context Language)-LUA programming language, and the tests have been carried out in two environments: 1) simulation with Ginga-NCL emulators and 2) using the Set Top Box (STB) EiTV Smartbox receiver equipment. The tests mainly detail the processes carried out to identify the audio and video formats supported in the two environments, the most appropriate options for integrating text in the interfaces, and the solution of problems encountered during the process. Finally, a usability analysis of the application is included with tests carried out in different age groups
Mass movements detection from UAV images analysus
(International Society for Photogrammetry and Remote Sensing, 2019) Achig Balarezo, Rosario; España Medina, Daniel Andres; Morocho Zurita, Carlos Villie; Crompvoets, Joep; Serrano Tapia, Ana Carolina
Biophysical conditions, the lack of governance and the weak applications of planning and territorial planning policies are aggravating factors of affections caused by natural disasters in Latin America. In Ecuador, landslides have caused not only material but also human losses, which shows the lack of immediate actions to avoid human settlements in risk areas or more controlled evacuations protocols, in case of early detection of risk areas due to this type of events. This article is part of an applied research project for the City of Cuenca allowing to take advantage of the information provided by citizens with a PPGIS. Furthermore, remote sensor images are analyzed, in order to identify in a semi-automated way, risk areas due to mass movements problems. Two approaches for semi-automated detecting areas where mass movements happen have been explored, i) Temporal images obtained by a LiDAR; and ii) Temporary images obtained by flights of an unmanned aerial vehicle, UAV. This paper present the procedure followed by comparison of image outcomes. The resulting analysis clearly presents the applicability of the two techniques thus allowing the determination of maps and early detection of landslides.
Prototype of a Centralized Alert and Emergency System for Digital Terrestrial Television in Ecuador
(Spriger Nature, 2021) Achig Balarezo, Rosario
Latin America is living the migration towards the digital terrestrial television (DTT) with the ISDB-Tb standard. Some countries have even had the analog blackout. In relation to the Emergency Warning Broadcast System (EWBS), the process of transmission and reception is defined. In recent years, tests have been coordinated for the process of implementing EWBS for DTT. The Common Alert Protocol (CAP) allows emergency alerts to be exchanged between different communication systems. This article presents the implementation of a CAP module in a Spatial Data Infrastructure for risk management and integration of the EWBS for DTT in a single platform for emergency alerts. A web service that contains the codes representing the cantons of Ecuador was obtained, selected through the use of a map viewer and integrated with an application that processes this information and generates the alert to be transmitted via DTT. The main objective is the storage of the information in a database, and a WEB RSS service that contains the information in conformance with CAP format. A series of experiments show successful outcomes.
Spatial data infrastructure as the core for activating early alerts using EWBS and interactive applications in digital terrestrial television
(Springer Verlag, 2019) Morocho Zurita, Carlos Villie; Achig Balarezo, Rosario; Santander Jaramillo, Darwin Fabian; Bautista Llivisaca, Mateo Sebastian; Achig Balarezo, Rosario
Integrated Services Digital Broadcasting Terrestrial (ISDB-T) is the standard adopted in Ecuador since 2010. There is a lack of proposals for taking advantage of communication alternatives with citizens, which the new digital technology will bring. The speed for alerting the community about dangers associated with natural hazards is an essential issue. There are many devices to alert population but none of them has the level of dissemination within households as the television does. This paper presents a software solution for early alert using the UCuenca-SDI (Spatial Data Infrastructure) core to activate an Emergency Warning Broadcasting System (EWBS) protocol in a Digital TV. The solution has two components (a) A schema to integrate the trigger module into the SDI, where the activation code is generated for EWBS. (b) An interactive app software developed over GINGA, where citizens can access …
Virtual Assistants to bring geospatial information closer to a smart citizen
(Institute of Electrical and Electronics Engineers, 2022) Bustamante Ávila, Juan Francisco; Mendieta Zumba, Juan Felipe; Achig Balarezo, Rosario; Morocho Zurita, Carlos Villie
This article presents a proposal for the use of virtual assistants integrated into a Spatial Data Infrastructure (SDI), which will facilitate citizen's access to available resources in creating geospatial information scenarios, without the need for increased knowledge or technical training. The chatbot would also allow access to SDI technology to be transparent to the citizen, allowing access to different map servers at the same time. The scenarios created refer to the main events registered in the National Risk and Emergency Management Service (SNGRE) of the country. The existing information is very data rich insomuch that the ordinary citizen does not know how to access its source. This project takes the initial steps for the integration of various sources of geospatial information with the goal to archive a core of geospatial information for services of City Intelligent. Ideally, this new form of access to geospatial information will also allow decision makers, using natural language, to have additional information to improve territorial planning and land use processes
