Issues in geographic data quality assessment by remote sensing techniques

The aim of this paper is to give considerations and suggestions that are relevant for the development of methods for the detection, updating, and evaluation of road extractors. This is done by presenting an example in which the quality of an existing road network is measured against image data. The focus of this paper is on practical issues, creating a link to fields that perhaps are not of direct importance to the image analysis community. This can help people to understand better the context in which the remote sensing image analysis takes place and hope it can be improved through the development of technologies and tools for mainstreaming the use of geographic information also for info-mobility services, including large-scale heterogeneous and distributed collection of geo-spatial data and for creating a sustainable landscape for geographic data creation, use, management and publishing.
