Red Bank High School worked with an international group to build maps, edit roads, bridges, housing, and crisis center locations so that first responders could use their smartphones and laptops to help those in peril during Hurricane Harvey, especially those in Houston, Texas. Local global leader in GIS and mapping, Randy Hale, indicated that OSM and other Open Source sites were receiving over 18,000 hits per minute for information on road closures and flooding, as map makers were working with responders to support those in need.

Red Bank High School students helped assist First Responders in wake of Hurricane Harvey. They spent countless days and whole class periods just to map everywhere they could in Houston to aid the first responders. Due to the sudden onset of Hurricane Harvey, students experienced a fast learning curve, teaching themselves how to map roads and houses in the affected area.

After the flooding of Hurricane Harvey in Houston, TX, two explosions at the flooded Arkema Chemical Plant in Crosby, TX (an area near Houston), occured. Black smoke spewed into the air and an intense fire burned for hours due to the explosion.
OSM HOT refused to help, so the U.S. took care of the two chemical explosions. With the help of Teach OSM, who gridded off Texas, we worked together to map the flooded state.
Crosby, TX, area of chemical plant explosions, gridded off on Teach OSM. Students had to lock and map in grid squares, then unlock them and mark them as done. This is indicated by the yellow percentage. Professional mappers (also students) than validated, or confirmed, that these sections were done (shown in the green percentage).
