In this monthly feature, we span the globe to examine Our Changing Landscape with time series of medium resolution RapidEye satellite imagery. The RapidEye archive dates back to late 2008 and already contains more than 10 billion square kilometers of data. Last month we explored a North Korean tourist destination for this Our Changing Landscape, and in July we check out the California 2017 super bloom in the southern part of this American state.
The RapidEye Constellation
RapidEye is a constellation of five 5-meter medium resolution satellites each offering five spectral bands of information. The RapidEye constellation offers daily revisits to every location on the planet with a huge footprint that is 77-km wide. The data is priced competitively with a starting cost of $1.28 per square kilometer for all five spectral bands – academics do receive discounts. RapidEye adds a fifth band, the red edge, to the ‘traditional’ multispectral set of blue, green, red and near-infrared (NIR). The additional spectral data in the red edge band allows users to extract more useful land ‘information’ than can be from traditional 4-band imagery sources. When RapidEye imagery is ordered as a Level 3A Orthorectified product, images from multiple dates are extremely well registered, making it the ideal data source for Our Changing Landscape.
2017 California Super Bloom
After years and years of one of the most extreme droughts in recorded history, southern California was pounded with rain in early 2017, with some areas seeing as much moisture in just six months as they would see in an entire year. And with these very welcomed and much-needed rains, came one of the most intense and gorgeous flower blooms in recent years – in fact, it was so intense that the flowering event has been dubbed the 2017 California super bloom.
According to many reports, one of the most colorful areas was Carrizo Plain National Monument in southern California. It appears that the super bloom reached peak colors in mid to late April depending on the exact location in the park. Carrizo Plain National Monument covers about 391 square miles (1,103 square kilometers) of some of the most pristine land left in southern California. The park is home to a wide array of animals, such as the bald eagle, the giant kangaroo rat and the Townsend’s big-eared bat, and then a number of flowering plants, such as the grass blazingstar, the Byron larkspur and the forked fiddleneck. Now without further ado, it is time to check out the amazing colors in the 5-meter RapidEye archive – can’t wait to see them!
