Digital Elevation Models (DEMs) are important datasets for modelling line-of-sight phenomena such as radio signals, sound waves and human vision. These are commonly analysed using rotational sweep algorithms. However, ...

Due to the global COVID19 pandemic, in the last few months there has been a dramatic change in the educational context where lecturers around the world has forced to solve academic problems that immediately before this ...

In recent years, approaches that seek to extract valuable information from large datasets have become particularly relevant in today's society. In this category, we can highlight those problems that comprise data analysis ...

Es muy frecuente, en los sistemas de información geográfica que trabajan con modelos digitales del terreno, el uso de algoritmos de barrido radial para el estudio de variables asociadas a parámetros cuya magnitud decrece ...

En apenas unos meses, y debido a la pandemia mundial del COVID19, se ha producido un cambio dramático en el contexto educativo que ha obligado a los docentes de todo el mundo a resolver problemas académicos que inmediatamente ...

In various applications such as hyperspectral data manipulation, MRI data exploration, or viewshed identification in digital elevation models, performing arithmetic operations on each point of a data mesh that involves ...

The 3D perception of the human eye is more impressive in irregular land surfaces than in flat land surfaces. The quantification of this perception would be very useful in many applications. This article presents the first ...
