One of the first major events to utilize crisis mapping was the 2010 Haiti earthquake , which killed and injured hundreds of thousands of people and left homes and infrastructure badly damaged . People who wanted to help started mapping the basic infrastructure , especially in OpenStreetMap , and were then able to do more detailed mapping as better resources became available . Crisis mapping in one form or another has been used in many crises since then . Many volunteers have also joined to help with data responses to crises and to build new information-handling tools for both crisis mappers and crisis responders in the field
