The study of urban growth has been important to the field of economics, and sociology for decades. At SpaceKnow, we use our AI based analysis of satellite image data to bring a vast array of earth observation data to the multiple uses cases of what could broadly be labeled urban growth studies. The growth of urban areas is generally important to understanding the economic development of regions, but can also be studied for more specific city planning issues, or wide ranging applications for political event monitoring. Indeed, clients have been using our urban growth analytics to study refugee crisis or displacement issues, military or other official land use, and modern studies of urban sprawl.
Technically, we do basic earth observation analysis of urban areas by pulling in historical low-resolution multispectral imagery and then using our algorithms to track the percentage of urban land cover
in selected geographic region(s). This is essentially a measure of the change from vegetative land cover to man made land cover. We make a simple version of this toolkit available on our website as a client driven, on demand first study. Examples of this follow:
Location: Cox Bazar, Bangladesh
Topic: Urban growth study
Context: Refugee camp growth – Due to the ethnic cleansing in Myanmar, the Bangladesh government has built one of the largest refugee camps for displaced persons in Cox Bazar. Analytics display both the visuals and data behind the camp’s growth over time.
