Note to companies or organizations planning to do a mapping project in Thailand

The OpenStreetMap community in Thailand is very proud of the high quality map data we created. We want to keep up this high standard.

If you plan a mapping project in Thailand, please contact the community in the forum beforehand. We can discuss your mapping ideas and point to things to consider. We offer our help to make OSM even more successful.

When deriving features from imagery it is crucial to check the alignment beforehand against multiple sources. If you consider mapping building footprints, it is important to create correct geometries, like right-angled walls and align with imagery. You also have to do some quality control and mentoring when bringing in large amounts of inexperienced mappers.

Also take note of the Organised Editing Guidelines.

Thailand OSM relation is 2067731 2067731

A nice tool from geofabrik labs was used to generate an animated gif of Thailand. It shows the progress of OSM in Thailand. A big THANK YOU to the community for making that huge progress. Keep on the good work.

Data sources

Aerial imagery

In addition to a survey with GPS one may also use some aerial images if available with a suitable license.

While Bing aerial imagery is available in many parts of the world and is the default layer in ID editor, it can be very outdated in rural areas of Thailand (often +5 years).

A recommended with more recent imagery would be Maxar and ESRI.

Landsat provides low-resolution satellite imagery of the whole country and is available with different image modes.

Official sources

Legislation and other official proclamations by the Royal Thai Government are exempt from copyright protection. Maps accompanying documents published in the Royal Thai Government Gazette (available at http://mratchakitcha.soc.go.th/ ) may be useful as sources for manual tracing (e.g. of national parks).

GIS data is available from several government agencies, but are presumed to be protected by copyright and unsuitable for import.

The Department of Highways provides a publicly accessible database of national highways at http://roadnet.doh.go.th. As above, the data is considered unsuitable for systematic import, but is useful as a source for confirmation of data and quality assurance.

The Department of Rural Roads publishes indices of rural highways at http://maintenance.drr.go.th/th/DRR. They include route numbers and names (which typically describe the route's start and end points), location, length, and start and end coordinates (although the coordinates appear quite unreliable).

The local highway registry is available at http://lmp.drr.go.th/lmp/waydata/main.html.
