The R-package scapesClassification is designed to translate users’ mental models of seascapes, landscapes and, more generally, of geo-spaces into computer representations (classifications). Spaces and geographic objects are classified with user-defined rules taking into account spatial data as well as the spatial relationships existing among different classes and objects.
Raster surfaces and objects
- scapesClassifications are performed on raster surfaces. The suit of available functions can be used to segment the raster space and to identify and manipulate distinct raster objects (i.e., groups of raster cells identified by a unique ID).
Key ideas
Landscapes and seascapes tend to have prominent features easy to identify. These features can be considered as anchor locations, locations around which a classification process can start and evolve.
A classification process can take into account the spatial relationships that are expected to exist among different classes, i.e., where a segment of space or an object is expected to be in relation to other segments and objects.
Based on such relationships, it is possible to estimate where a certain class is expected to exist and to perform focal evaluations of classification rules: rules are only evaluated at suitable locations, thus, limiting possible misclassification cases.
A classification process is seen as multi-step: as new portions of a raster are classified they can be used to define new focal areas over which classification rules are evaluated.
