Spatial data is used in geographical information systems (GIS) and other geolocation or positioning services. Spatial data consists of points, lines, polygons and other geographic and geometric data primitives, which can be mapped by location, stored with an object as metadata or used by a commun...
Spatial data science is a subset of data science. It’s wheredata science intersects with GISwith a key focus on geospatial data and new computing techniques. Location matters in data science using statistical computing to access, manipulate, explore, and visualize data. Having latitude and longitu...
Thegeographydata type methods that require the input of twogeographyinstances, such asSTIntersection(),STUnion(),STDifference(), andSTSymDifference(), will return null if the results from the methods do not fit inside a single hemisphere.STBuffer()will also return null if the output exceeds a...
Nonnegative matrix factorization (NMF) is widely used to analyze high-dimensional count data because, in contrast to real-valued alternatives such as factor analysis, it produces an interpretable parts-based representation. However, in applications such

Spatial data is one of the most common data types in our everyday life, and it refers to all types of data objects or elements that are present in a geographical space or horizon. It enables the global finding and locating of individuals or devices anywhere in the world. Spatial data is...
Spatial data are different from nonspatial data due to the complexity of spatial data (e.g., multidimension and autocorrelation) and spatial relationships (e.g., adjacency, connectivity, direction, and inclusion). There are several major knowledge constructions for spatial data mining: spatial cluste...
To address these limitations, we present SpatialScope, a unified approach integrating scRNA-seq reference data and ST data using deep generative models. With innovation in model and algorithm designs, SpatialScope not only enhances seq-based ST data to achieve single-cell resolution, but also ...
