Satellite images captured the catastrophic floods that hit Pakistan on August 1, 2010 the worst since 80 years which have affected 14 million people. As many as 12 million people have been affected by the torrential rains and floods and about 1,300 people have died.
A total of 650,000 houses have been damaged or destroyed and up to 500,000 people are homeless in Punjab province. At least 1.4 million acres of farmland were destroyed in the province, where people rely heavily on agriculture for food.

The satellite images above were taken from the Worldview-2 and QuickBird satellite sensor and shows the pre and post flooding in northern Pakistan standing water burying farmlands and settlements.
Flooding of the Kabul River meanders over flat ground near the area, and standing water outside of the river’s banks formed large loops of water similar in shape to the river’s path. Flooding is especially severe in the northwest, although this may result partly from the absence of many high-profile features in that area.
Satellite Imagery and Mapping of Natural Disasters
Emergency managers use remote sensing and mapping tools such as satellite imagery and GIS can facilitate critical decision-making before and after a disaster impacts an area. In the early, crucial stages of a disaster or emergency and throughout the disaster process, managers use satellite imagery and GIS products because they provide important information, in quick and easy-to-understand formats.
Remote Sensing gives state and government agencies the ability to view the damage from multiple vantage points. The spatial resolution of an image determines the ability to view individual features such as buildings and bridges. It also affects the ability to monitor and assess damage conditions, and depends on the nature of the hazard itself.
