This research identifies places that concentrate a large proportion of activity in Singapore, and explores a methodology to characterize them based on features of the physical environment, demographics and arrangements of activity. The methodology utilizes a spatial-temporal algorithm of pattern detection based on cellphone data aggregated into a “SpotRank” score of hourly relative frequencies within 100×100 meter cells.  Our study shows a rich variation in the spatial and temporal scales of popular destinations, as well as their internal distribution and mix of activities. Identifying and characterizing ‘non-work destinations’ requires consideration of several dimensions and scales. However, this blend and spatial structure provide rich information about the character and location of non-work trips.
