Detection of potential updates of authoritative spatial databases by fusion of volunteered geographical information from different sources
نویسندگان
چکیده
A continuous update of authoritative spatial databases is highly demanding task in both aspects, technical and financial. In the same time, alternative modalities to collect content, in particular spatial content, have achieved a certain maturity and must be considered as they may leverage the cost of updating authoritative spatial databases (Al-Bakri, 2010). This alternative data known as Volunteered Geographical Information – VGI (Goodchild, 2007) is easy available and is being collected in almost every moment somewhere in the world.

With volunteered geographic information (VGI) platforms such as OpenStreetMap (OSM) becoming increasingly popular, we are faced with the challenge of assessing the quality of their content, in order to better understand its place relative to the authoritative content of more traditional sources. Until now, studies have focused primarily on developed countries, showing that VGI content can match...
متن کاملA geographic approach for combining social media and authoritative data towards identifying useful information for disaster management
In recent years, social media emerged as a potential resource to improve the management of crisis situations such as disasters triggered by natural hazards. Although there is a growing research body concerned with the analysis of the usage of social media during disasters, most previous work has concentrated on using social media as a standalone information source, whereas its combination with ...

Due to the differences between the visible and thermal infrared images, the combination of these two types of images leads to better understanding of the characteristics of targets and the environment. Thermal infrared images are really in distinguishing targets from the background based on the radiation differences and land surface temperature (LST) calculation. However, their spatial resolu...

Geotagged tweets to inform a spatial interaction model: a case study of museums This paper explores the potential of volunteered geographical information from social media for informing geographical models of behavior, based on a case study of museums in Yorkshire, UK. A spatial interaction model of visitors to 15 museums from 179 administrative zones is constructed to test this potential. The ...
متن کاملEvaluation of Updating Methods in Building Blocks Dataset
With the increasing use of spatial data in daily life, the production of this data from diverse information sources with different precision and scales has grown widely. Generating new data requires a great deal of time and money. Therefore, one solution is to reduce costs is to update the old data at different scales using new data (produced on a similar scale). One approach to updating data i...
