This job is part of USAID/OFDA and USGS/VDAP’s continued efforts in DRR mapping of volcanic hazards in Indonesia pre-disaster.
Gamalama is an active stratovolcano that constitutes the entire island of Ternate in the Maluku Islands. Roughly 310,000 people live within a 50 kilometer radius of Gamalama.
Volunteers will create and improve existing infrastructure data, with a focus on tracing buildings, roads, and inland water features. Existing data consists of road features 2-4 years old--please take care to edit the roads as needed.
The main priority city is Ternate City, directly adjacent to Mt. Gamalama. Other coastal cities to map are Tahua, Dojado, Mareko, and Soasiu.
Through the MapGive project, the Humanitarian Information Unit (HIU) of the U.S. Department of State is providing the OpenStreetMap community access to updated satellite imagery services to help assist with humanitarian mapping.

You need to review and acknowledge the agreement.
Volunteers are asked to map buildings, roads, and inland water. Existing data was added before quality imagery was available. There may be instances where editing existing road data is appropriate. If there are too many features to map in a selected tile, please split the tile as necessary.

Imagery Details This imagery is from Digital Globe’s WorldView-3 and WorldView-2 satellites, and composed of images that were taken on August 18, 2015 and January 03, 2015. The images are orthorectified for terrain corrected geographic precision. Additionally, the images have been contrast stretched using a custom stretch and processed into a Tiled Map Service (TMS) for performance.
