WIFI indoor positioning for mobile devices, an application for the UJI Smart Campus
Dissertation submitted in partial fulfillment of the requirements for the Degree of Master of Science in Geospatial Technologies.Smart Campus has emerged as a study platform of a Smart City. There are some
similarities between the Campus and a City. Due to this, is possible use a Smart
Campus as attesting bench and then apply these investigations to implement in a
Smart City. One of this potential technologies is the Indoor Positioning System
using the Wi-Fi network. The aim of this work is research and implement a
mobile application to carry out the indoor positioning in the context of the UJI
Smart Campus. The prototype developed allows to perform the first part of the
Wi-Fi Indoor Positioning, the mapping phase. This application implements a
system to display and all UJI cartography (campus basemap, UJI buildings and
UJI buildings interiors). When whole system will be developed, it will allow
implement the indoor positioning in a future applications for the Smart Campus
UJI Smart Venues: Gestión de eventos en la Universitat Jaume I de Castelló
Ponènica presentada a les V Jornadas Ibéricas de Infraestructura de Datos Espaciales (JIIDE 2014), celebrat a Lisboa els dies 5-7 de novembre de 2014UJI SmartVenue es una aplicación móvil que se benef
icia de los servicios de la
implantación de una IDE (Infraestructura de Datos E
spaciales) sectorial
basada en la plataforma ArcGIS y los aplica a la ge
stión de un evento. A partir
de la base de datos espacial, y los servicios de ma
pas, datos y
geoprocesamiento asociados que proporcionan informa
ción relativa a la
universidad, se permite al organizador del evento a
sí como a los asistentes
situar cada actividad en su ubicación y horario det
erminados para facilitar el
acceso a las salas o valorar la asistencia entre ot
ros. La información se
presenta en mapas 2D o por realidad aumentada a tra
vés de la cámara del
dispositivo móvil.
Los usuarios pueden realizar acciones como: buscar
y guardar sus actividades
favoritas, planificar su agenda, calcular el trayec

beneficiarse del sistema de posicionamiento en inte
riores implantado en la
Universitat Jaume I para calcular la ruta desde su
posición real sin necesidad
de conocer el edificio, y recibir alertas o publica
r comentarios (en redes
sociales) basados en su agenda y ubicación.
Además, este servicio permite a la organización con

Airborne light detection and ranging (LiDAR) point density analysis
The point density is a preeminent parameter on airborne laser scanner surveys. It is not only related to accuracy but costs and savings. The lack of uniformity of the point density across the survey is well-known in the scientific community. This paper analyzes the behaviour of the point density derived by an oscillating mirror laser scanner on different single strips on flat bare ground in order to estimate a meaningful mean density value. The variation of the point density at both extreme ends of the oscillating mirror scan is meaningful. It will be demonstrated that excluding the extreme sectors across the strip corresponding to 1/8 of the swath width (12.5% of the sampling area, half in each side) for the computation of the mean density value is enough to satisfy light detection and ranging (LiDAR) specifications for national level surveys.Balsa Barreiro, J.; Avariento Vicent, JP.; Lerma García, JL.

Enhancing integrated indoor/outdoor mobility in a smart campus
A Smart City relies on six key factors: Smart Governance, Smart People, Smart Economy, Smart Environment, Smart Living and Smart Mobility. This paper focuses on Smart Mobility by improving one of its key components: positioning. We developed and deployed a novel indoor positioning system (IPS) that is combined with an outdoor positioning system to support seamless indoor and outdoor navigation and wayfinding. The positioning system is implemented as a service in our broader cartography-based smart university platform, called SmartUJI, which centralizes access to a diverse collection of campus information and provides basic and complex services for the Universitat Jaume I (Spain), which serves as surrogate of a small city. Using our IPS and based on the SmartUJI services, we developed, deployed and evaluated two end-user mobile applications: the SmartUJI APP that allows users to obtain map-based information about the different facilities of the campus, and the SmartUJI AR that allows users to interact with the campus through an augmented reality interface. Students, university staff and visitors who tested the applications reported their usefulness in locating university facilities and generally improving spatial orientation
