WE NEED A LITTLE HELP TO FINISH THIS PROJECT AND VALIDATE - PLEASE USE THE IMAGERY LINKED IN THE INSTRUCTIONS TAB (should load automatically) - DO NOT USE BING

Disaster Assessment is one of the five essential tasks that the Red Cross is required to perform during a disaster. A timely and accurate preliminary damage assessment will assist in helping leadership to appropriately budget, supply, and staff a disaster operation. To help build our capacity to do disaster assessment in American Samoa we will be mapping all of the buildings and roads on the main islands. This will give us a better understanding of what buildings and infrastructure were in place before a disaster to compare against the damage after a disaster.

This task focuses on tracing buildings and creating a complete transportation network.

Buildings: please label all buildings as general buildings, unless they clearly appear to be residential homes (house). Square the corners of all buildings by pressing “S” on your keyboard after labeling the building. Note: Some buildings may have already been traced from previous imagery - if you notice that they have changed or need to be shifted please adjust them according to the current imagery.

Roads: most roads have already been mapped, but please check their completeness and add any missing ones. Road classification should be based on the actual functional role and not on the surface or the visual appearance.

Note: if you see other map features that can be easily recognized from the imagery such as water storage tanks, drains, piers, athletic fields, etc, please feel free to map them and then apply the corresponding tag (from the search box).

DO NOT edit the coastline (light green) or any administrative boundaries (blue and white dashed).

Tracing tips: Save often when editing long linear features such as roads. These features are continuous and appear in multiple cells across the project area which can cause errors when edited by multiple users.
