Hurricane Harvey Imagery Viewer

Welcome. This application displays before-and-after aerial imagery of locations affected by Hurricane Harvey.

Instructions
  • Use the search box in the upper-right corner to find an address or look up a business, neighborhood, or other place by name. The map will automatically zoom to and place a marker at that location.
  • "Before" imagery appears on the left side of the map divider, and "after" imagery appears on the right. Drag the divider left and right to compare the before and after views.
  • On touchscreen devices, pinch the screen to zoom the map. Otherwise, zoom the map by scrolling your mouse wheel or by clicking the +/- buttons in the upper-left corner.

Click the checkbox next to an individual layer to turn it on and off, or click the switch next to a provider's name to toggle all layers from that source.
