Supplement
Global Map data of National/Regional version were developed with consistent specifications by NGIAs of respective countries and regions for fundamental geospatial information of their respective coverage by using geospatial information owned by them, and they were provided. The data have been authorized by NGIAs of respective countries and regions. Therefore, the contents of respective data are based on the views of respective data developers. For some countries and regions, there may be parts where data have not been developed.
National/Regional version of Global Map data was to be updated in about five-year cycle on the basis of resolutions of an ISCGM meeting. To know about the year data were updated and about data developers, please refer to metadata attached to each data.
Depending on the period the data were prepared, they were developed in line with two different specifications, namely, version 1 in VPF and BIL formats, and version 2 in GML and BIL formats.
National/Regional version of Global Map data were provided from this website or websites of respective countries and regions and they are available for download. For non-commercial use, in principle, anyone can use the data free or charge. In using the data, please check respective data policies because different countries and regions have different data policies.
