The focus area is the Mississippi River floodplain along the western edges of Jackson, Union and Alexander counties in Illinois. This a rural, impoverished area that has been severely impacted by flooding. The communities between the river and the high, wooded bluffs of the Shawnee National Forest need help with basic map data to represent their area in the discussions about their future existence. The area is a mix of agricultural land and wooded wetland swamps with a few very small towns. It's a small task; the total population of the whole area is approximately 2,000 people in an area of about 300 square kilometers.

- Mississippi River floodplain community basemap When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".
Communities to focus on are Grand Tower, Wolf Lake, Ware, Reynoldsville, McClure and East Cape Girardeau. The structures on the surrounding farmland are equally important. The map is also missing many pieces of publicly-owned land (mostly US Forest Service parcels) and representations of land use.
High resolution imagery of the area was captured during the early days of the flood event for this area. It is the highest resolution imagery of the area available and it is suitable for identifying building but PLEASE DO NOT USE THE IMAGERY TO MAP FLOOD EXTENT or LAND COVER. The water continued to rise another 50cm after the imagery was collected. Using that imagery to portray the extent of the flood would significantly under-represent the event for this area. Also many areas that are normally agricultural fields were too wet to plant this year should not be used to map land cover.
