A 'data structure' is the logical view, and a 'file structure' is the actual physical arrangement of the data. Spatial data, as used in geographic information systems, gives rise to particular problems in deriv
1.3 Geographic Information System Data Models The basic data models in GIS are: 1.3.1 spatial data; 1.3.2 attribute data. 1.3.1 Spatial Data Spatial data comprise the relative geographic information about the earth and its features. A pair of latitude and longitude coordinates defines a specific...
Spatial clustering, which shares an analogy with single-cell clustering, has expanded the scope of tissue physiology studies from cell-centroid to structure-centroid with spatially resolved transcriptomics (SRT) data. Computational methods have undergone

This chapter provides a survey of the specification and estimation of spatial panel data models. Five panel data models commonly used in applied research are considered: the fixed effects model, the random effects model, the fixed coefficients model, the random coefficients model, and the multilevel...
"The first half of this book certainly convinced me that some extra effort in organizing my data into certain spatial class structures makes the analysis easier and less subject to mistakes. I also admit that I found it very interesting and I learned a lot. Several years ago, I struggled on...
As outlined in theearlier Spatial Subdivisions post, not all spatial data structures are equal. But how well do our tweaks to the classic quadtree/octree algorithm hold up in practice? In the case of 3D Tiles for streaming to Cesium, we evaluate tilesets using a couple of questions including...
Public health professionals who collect such data are charged not only with surveillance, but also statistical inference tasks, such as modeling of trends and correlation structures estimation of underlying model parameters hypothesis testing (or comparison of competing models) prediction of observations at...
Annotating tissue structures provides an important layer of biological interpretation from spatial molecular data. Uniform and consistent identification of structures across different batches, experiments, and diverse disease conditions remains a challenging task, often requiring manual intervention. The generaliza...
