Witryna5.1 Introduction. So far the book has explained the structure of geographic datasets (Chapter 2), and how to manipulate them based on their non-geographic attributes (Chapter 3) and spatial relations (Chapter 4).This chapter focuses on manipulating the geographic elements of geographic objects, for example by simplifying and converting … Witryna11.2.2 Local density. A point pattern’s density can be measured at different locations within the study area. Such an approach helps us assess if the density–and, by extension, the underlying process’ local (modeled) intensity \(\widehat{\lambda}_i\) –is constant across the study area. This can be an important property of the data since it …

WitrynaRaster functions. Raster functions are operations that apply processing directly to the pixels of imagery and raster datasets, as opposed to geoprocessing tools, which write out a new raster to disk. Calculations are applied to the pixels of the original data as … WitrynaThe Local functions allow you to perform bitwise, conditional, logical, mathematical, and statistical operations on a pixel-by-pixel basis. Depending on the operation type, it may require 1, 2, 3 or n input rasters. You may need to stack a few Local functions together in order to achieve some of the conditional and logical functions. WitrynaRaster operations performed on multiple input raster datasets generally output cell values that are the result of computations on a cell-by-cell basis. The value of the output for one cell is usually independent of the value or location of other input or output cells. ... Local functions.

The very back end of the pipeline, raster operations (often called the ROP), is responsible for reading and writing depth and stencil, doing the depth and stencil comparisons, reading and writing color, and doing alpha blending and testing.

Local space is the coordinate space that is local to your object, i.e. where your object begins in. Imagine that you've created your cube in a modeling software package (like Blender). The origin of your cube is probably at (0,0,0) even though your cube may end up at a different location in your final application.
