Global map of the Coastal Points Database (CPD). Blue coastlines represent locations included in the CPD, where tide and wave conditions were extracted and where the local indicative meaning can be calculated. Points where no data could be extracted is also shown here (red coastlines), but are not included in the CPD. Points above 60°N or below 60°S were removed from the CPD, in order to exclude polar regions. Additionally, locations of the K09 database ([8], yellow pentagons) are displayed
