, 2017 The concept of Volunteered Geographic Information (VGI) is often exemplified by the mapping of features in OpenStreetMap (OSM), yet there are many other sources of VGI available. Some VGI is very focused on the creation of map-based products, while in other applications location is simply one attribute that is routinely collected, due to the ...

Quality of GNSS Traces from VGI: A Data Cleaning Method Based on Activity Type and User Experience
ISPRS Int. J. Geo Inf., 2020 VGI (Volunteered Geographic Information) refers to spatial data collected, created, and shared voluntarily by users. Georeferenced tracks are one of the most common components of VGI, and, as such, are not free from errors.

Newtonian versus relativistic cosmology
, 2012 We show how the relativistic matter and velocity power spectra behave in different gauges. We construct a new gauge where both spectra coincide with Newtonian theory on all scales.

Towards Automatic Extraction and Updating of VGI-Based Road Networks Using Deep Learning
Remote Sensing, 2019 This work presents an approach to road network extraction in remote sensing images. In our earlier work, we worked on the extraction of the road network using a multi-agent approach guided by Volunteered Geographic Information (VGI).

A Guidance Tool for VGI Contributors [PDF]
, 2015 Many people are familiar with the VGI project OpenStreetMap (OSM), but there are many other projects that are not as well known to volunteers. What is needed is a tool that can help volunteers match their motivations, interests and background to ...
