Using satellite imagery from Planet, Bellingcat has surveyed the extensive damage to areas near Houston due to Hurricane Harvey. The majority of post-Harvey imagery available is for southwest and southern Houston and Galveston, with little imagery available for eastern and northern parts of the area.
Some of the most devastating damage can be seen along the Brazos River, southwest of central Houston.
