In each parking spot the standard deviation, range, and variance is calculated for 3 color bands and one near-infrared band of a commercial Pleiades satellite image. Besides that, the NDVI mean and max of each parking spot is also included. Additionally a classification of the images is provided in the matrix column, where it was determined using Triangle thresholding if a car is parked in the parking spot. 1 - marks a parked car, 0 - marks no car, and -1 means that the NDVI value was too high to classify the parking spot. Finally the occupied column represents ground truth. It was determined based on video footage taken two minutes before and after the satellite image was taken, 1 - represents an occupied parking spot, 0 - an empty parking spot and NULL means no data was recorded for that parking spot."}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Earth and Environmental Sciences"]},{"typeName":"notesText","multiple":false,"typeClass":"primitive","value":"This research was supported by the NWO-funded Urban Mobility Observatory (UMO) project that aims to collect, store and share traffic, transport and mobility related data.
