Positional Accuracy Assessment of the VGI Data from OpenStreetMap: Case Study: Federal University of Bahia Campus in Brazil

摘要

Geographic information is a crucial part of the daily lives of billions of people and is constantly used in decision-making processes for geospatial problems. With the increasing dissemination of information technology in society there has been a great gain in terms of the quantity and quality of spatial information available to internet users. This paper evaluates the positional quality of data from the Open Street Map platform (OSM) and uses data from a cartographic accuracy standard from the same region for this evaluation. The methodology section presents the methodology proposed by the Brazilian PEC-PCD which divides cartographic products into accuracy classes. For the data evaluated, the vectors from the OSM obtained better accuracy in the 1:30,000 scale.
