Suitability of Open Street Map (OSM) for 1:50,000 Topographic Map

Abstract

Open-source data is open for anyone and everyone for access, modification, reuse, and sharing for particular application. Open-source data is compiled from various sources using public user collaboration. Open street map is one of open-source vector provider. The suitability study of the use of open-source data for the production of topographic maps of various scales is important as a new approach. The importance of the feasibility study of the use of open-source data can help improve the efficiency of the production of mapping products. Many methods of producing topographic maps of various scales use various state -of -the -art technologies for fast and efficient map production. The objective of the study is to check the planimetric accuracy and feature geometry of open-source vector datasets. Conventional methodologies for the production of multi -scale topographic maps are time consuming and involve high costs. Therefore, open-source data is an alternative source for the production of topographic maps of various scales. This data source shows the potential use for generation of multiple data layers such as roads, points, places, waterways, railways, natural, buildings and land use. The planimetric accuracy of open-source vector data is ranging from 2-5 m. The overlay analysis between reference dataset and open-source data show the similarity geometry for 1:50,000 map scale. This method shows a high level of suitability for the efficient updating of topographic data and the production of topographic maps for 1:50,000 map scale.
