The Spatial PL/SQL application programming interface (API) includes several operators and many procedures and functions. Spatial operators, such as SDO_FILTER and SDO_RELATE , …

Table 20-1 lists the main operators. Specifies which geometries may interact with a given geometry. Performs a spatial join based on one or more topological relationships. Determines …

Spatial analysis is a fundamental component of a GIS that allows for an in-depth study of the topological and geometric properties of a dataset or datasets. In this chapter, we discuss the …

In the previous chapter we have seen a number of basic spatial analysis operations used for the retrieval, (re)classification and measurement of point, segment, polygon, and raster maps.

Set algebra consists of four basic operators: less than (<), greater than (>), equal to (=) not equal to (<>). In some programming environments (such as R and Python), the equality condition is …

In the context of spatial analysis, the analysis focuses on the statistical analysis of patterns and underlying processes or more generally, spatial analysis addresses the question “what could …

Spatial operations, including spatial joins between vector datasets and local and focal operations on raster datasets, are a vital part of geocomputation. This chapter shows how spatial objects …

where A and B are linear operators with respect to U. For example, operator A may represent a time convolution, time integration or a multiplication operator with a given kernel. Similarly, the …

Spatial query is a query method that selects map features based on their spatial relationships to other feature. Currently, 8 spatial query operators are supported. They are: Cross, Contain, …
