Isle de Jean Charles (known locally in Louisiana French as Isle à Jean Charles) is a narrow ridge of land situated in Terrebonne Parish, Louisiana. For over 170 years it has been the historical homeland and burial ground of the state-recognized tribe of the Isle de Jean Charles Band of Biloxi-Chitimacha-Choctaw Indians. Residents of the Island have long been threatened by Louisiana's coastal erosion (coastal Louisiana loses a landmass the size of Manhattan every year). The Island, which consisted of over 22,000 acres of land in 1955, has lost about 98% of its land since due to saltwater intrusion, subsidence, and sea level rise. In January 2016, the state of Louisiana received substantial funding from the United States Department of Housing and Urban Development to fund the tribe's resettlement to safer ground.

INSTRUCTIONS: Please trace all the buildings and roads that you can see on the imagery. Tag each building as simply "building" - as we cannot always be sure of the building use from aerial imagery.
Tag the roads according to perceived type and usage. Please consult the OSM tagging dictionary for roads: http://wiki.openstreetmap.org/wiki/Map_Features#Highway
When saving your work, please leave the default comment and add what you actually mapped. For example "added buildings and a residential road".
ADVANCED TIPS: * Toggle between Bing imagery and Mapbox imagery to help identify features. One set of imagery may offer sharper image, easier recognition of objects on the ground.
Add TIGER streets to your background imagery for reference and comparison with OpenStreetMap data: - In iD, open the Background preferences, and tick the box for 'New & Misaligned TIGER Roads' - In JOSM, open the Imagery menu, and select TIGER 2012 Roads Overlay
Re-align OpenStreetMap data to the imagery. If the TIGER is acceptably correct, use it for naming. - Tag roads according to usage. In most cases, this will be 'unclassified' or 'unknown'. Refer to the wiki section on tagging road features.
