Tentative Tests on Two Rapid Multispectral Classifiers for Classifying Point Clouds

This paper focusses on the feasibility of classifiers, developed for classifying multispectral images, for assigning classes to point clouds of urban scenes. The motivation of our research is that dense point clouds require fast classification methods to extract meaningful information within a reasonable amount of time and multispectral...

Exploring indoor movement patterns through eduroam connected wireless devices

Knowledge of people's locations and related mobility patterns are important for many decision-making processes. How to efficiently use the available space, is a common problem in many fields. Wireless Local Area Networks (WLAN) are widely used for locating mobile devices within this network. This study attempts to identify movement from Wi-Fi...

Point Cloud Based Visibility Analysis: first experimental results

Visibility computed from a LiDAR point cloud offers several advantages compared to using a gridded digital height-model. With a higher resolution and detailed information, point cloud data can provide precise analysis as well as an opportunity to avoid the process of generating a surface representation or a solid model. Also a better inclusion...

Using a generic spatial access method for caching and efficient retrieval of vario-scale data in a server-client architecture

This paper presents a methodology for using a generic data-driven spatial access method as a communication mechanism for vario-scale data in a server-client setting. As a complete data set is often quite large, it is managed at the server side and supporting different scale levels is important. We show that a generic R-tree like grouping method,...

Archiving AIS messages in a Geo-DBMS

This paper reports on the result of two studies for using a geographical database management system for archiving Automated Identification System (AIS) message data. In this paper, we analyse the storage (using MongoDB and PostgreSQL) and we give a more in-depth description of a possible data model for archiving messages based on the bit vector...

Multi-Domain Master Spatial Information Management for Open SDI in Indonesian Smart Cities

Spatial Information Infrastructure (SDI) has great potential to support smart city by providing framework dataset and real-time information services in urban informational infrastructure, the social infrastructure and citizen's participation practices. Bandung City and Jakarta City are maintaining their SDI for various kinds of decision-making...

Impact Modelling for Circular Economy: Geodesign Discussion Support Environment

Transitioning towards circular economy requires changes in the current system which yield a number of impacts on such fundamental values as human health, natural environment, exhaustible resources, social well-being and prosperity. Moreover, this process involves multiple actors and requires careful considerations of ample spatial information....
