Unified GIS database on cycle tourism infrastructure

Bicycles are used in the Czech Republic for commuting to work and for leisure time activities. This is reflected in the cycle trail administrators' offer to make the existing network denser, design new routes, mark their courses and install a complementary cycle infrastructure. However, extensive growth of these activities in the last years has led to the loss of overview information on the overall cycle trail network. That is the reason for producing a methodology of capturing and representing the information. A unified GIS database on the cycle infrastructure (UDCI) was created and includes a data collection system with the use of GPS, the coding of descriptive information on cycle trail segments and the administration of GIS layers in a topologic data model. The methodology of the UDCI application is demonstrated with a specific example of a cycle trail network in the South Bohemian region. (C) 2012 Elsevier Ltd. All rights reserved.
