Temporal and spatial trends in air quality in Beijing
Landscape and Urban Planning, 2019Air quality is one of the most critical environmental issues in Beijing, China. In this study, temporal and spatial variations in air quality in Beijing are characterised by two aggregate indexes, the air pollution index (API) and air quality index (AQI).

The Professional Geographer, 2011
With many leading spatial analysts nearing retirement, reflection on the discipline becomes beneficial. To capture some of their collective perspective, fifty-eight researchers were surveyed on key spatial analysis developments, future challenges, and essential readings for newcomers.

Recent Trends in Urban Spatial Structure
Growth and Change, 1980Results of an investigation of the existence and significance of employment concentrations outside the central business districts of large metropolitan areas are presented. Trends in the intrametropolitan location of employment during te 1960s and early 1970s are examined by using small-area data for two points in time.

AntTrend: Stigmergetic Discovery of Spatial Trends
2006Large amounts of spatially referenced data have been aggregated in various application domains such as Geographic Information Systems (GIS), banking and retailing that motivate the highly demanding field of spatial data mining. So far many beneficial optimization solutions have been introduced inspired by the foraging behavior of ant colonies.

Spatial Patterns of Globalization Trends
2011In the first part of this book, close attention has been paid to the importance of a regional analysis of globalization trends since these are expected to be spatially differentiated, and to have diverse impacts not only at the national, but especially at the regional level.

Hyperspectral images (HSIs) have a cube form containing spatial information in two dimensions and rich spectral information in the third one. The high volume of spectral bands allows discrimination between various materials with high details.

Spatial trajectories segmentation
Proceedings of the 5th ACM SIGSPATIAL International Workshop on Mobile Geographic Information Systems, 2016Given a sequence S of temporally ordered observations, non necessarily of spatial nature, the segmentation task partitions S in a set of disjoint sub-sequences si, .., sn - the segments - such that ∪i∈[1, n]si = S. Typically, segments represents sub-sequences that are somehow homogeneous with respect to some criteria.

Spatial trend concept is very useful in order to depict the systematic variations of the phenomenon concerned over a region based on geographical locations or as in this book based on two independent variables that may be any other two event records.
