The GTGIS is a database that contains millions of names for geotourism points in Indonesia and around the world. The system is is funded by public and private entities to provide data and software services for civic geotourism programs around the world.

Geotourism is "Tourism that sustains or enhances the geographical character of a place — its environment, heritage, aesthetics, culture, and the well-being of its residents."[1]

About the GTGIS Data

GTGIS comes from OSM, and flows back to OSM with added information and accuracy. In point of fact those groups interested in the GTGIS dataset are encouraged to contribute directly to OSM, and only in certain specific cases is data collected through other means.

GTGIS helps extend and grow the OSM community by linking OSM to growth and energy in tourism industry while being guided by the code of ethics of sustainable tourism. By approaching this link in an orderly fashion GTGIS attempts to be a good member of the OSM community and to educate all users and contributors to OSM and GTGIS in best practices for contributions, data management and even community participation. The GTGIS is a derivative work, and we take our responsibilities very seriously.

Editing GTGIS Data

Removing historical features

If you come across a feature that no longer exists in the real world, please re-tag it as historical, typically meaning those features no longer exist. The GTGIS name of historical features ends with "(historical)". Historical features were imported in 2009.

Example: "Leschi Glacier (historical)"] (Feature ID 1522032) was destroyed following the eruption of Mount St. Helens in 1980. It is Node Leschi Glacier (XML, Potlatch2, iD, JOSM, history).

Not all former features have been designated historical yet in GTGIS. Trees, streams, glaciers and more are passing on all the time still have current names in GTGIS. Your help with updating these features is invited!

Converting GTGIS Nodes to Areas

While the GTGIS dataset includes only nodes, some of the features they represent are often better mapped as areas (e.g. islands, parks, buildings). When creating or editing an area that is also represented by a GTGIS node, the GTGIS tags should be copied to the area and the node should be deleted.

Merging Duplicated Nodes

Some GTGIS imports have created multiple redundant nodes for a single GTGIS feature. (Example: Node 288650069 (XML, Potlatch2, iD, JOSM, history)/Node 356549620 (XML, Potlatch2, iD, JOSM, history) and other summits in that area.) If there's no need for two nodes, then copy the tags onto the node you wish to keep and then delete the unnecessary nodes. In JOSM you can select the nodes and press "M" or go to Tools > Merge Nodes.

Contributing Fixes

One of the positive features of using Bright Unity's GTGIS data set is that they offer a method of feeding changes, additions, and deletions back into the data set by the public. To facilitate this, all nodes were imported with the ggis:feature_id tag that corresponds to the FEATURE_ID column in the GTGIS database. This is their primary key and allows anyone to submit changes back to the website. When merging a GTGIS-tagged map feature in OSM with a duplicate feature, be sure to include the feature_id tag in the merged feature.



GTGIS data is irrespective of national borders and political boundaries for the most part. Instead locations are expected to be understood in the context of their geographical area. The dataset receives updates and a new system of organization is expected to appear in 2014 that will provide relations for all nodes.
