Unit 5 - Raster Data Analysis And Data Display | PDF | Map | Contour Line

Unit 5 - Raster Data Analysis And Data Display | PDF | Map | Contour Line In computer graphics and digital photography, a raster graphic, raster image, or simply raster is a digital image made up of a rectangular grid of tiny colored (usually square) so called pixels. 由于光栅化将矢量图形转换为位图图形，因此它也被称为栅格化。 栅格化是德语raster的音译，意思是栅栏。 在光栅化过程中，像素就像栅栏上的格子，将图像分割成一个个小块。 claude：光栅化之所以叫光栅 (rasterization)，是因为它是基于光栅扫描原理实现的。.

Lecture 6 Raster Analysis | PDF | Mathematical Analysis | Mathematics Raster是英语名词，音标为英式/ˈræstə/、美式/ˈræstɚ/，在电子技术领域特指由规则排列的横纵线条组成的成像结构。 该词广泛应用于电视显像、计算机图形处理和光学测量领域，构成如raster display（光栅显示器）、raster scan（光栅扫描）等专业术语。. 栅格（raster）和影像（images/imagery）在gis应用中经常被相互指代。 如果非要区别一下呢，影像是指通过各种遥感设备，传感器，或者照相机得到的电子的或者纸质的图片，栅格则是一种数据模型，用来特指影像存储方式的。. Typically, the pixels are stored in computer memory as a raster image or raster map, a two dimensional array of small integers. A raster graphic is made up of a collection of tiny, uniformly sized pixels, which are arranged in a two dimensional grid made up of columns and rows. each pixel contains one or more bits of information, depending on the degree of detail in the image.

Also known as bitmap, raster files work best when you need to store and display high quality photographs. most photos come in the raster file format, whether they’re print or digital. 其中三角形就是最常用的 geometric primitive 1. raster images 了解光栅化之前，我们先来了解一下什么是像素点。 我们日常用的显示器，就是将一幅图以 像素矩阵 来显示的，我们在屏幕上见到的物体实际上都是由一块块像素模拟出来的（大家都玩过我的世界吧）。. In its simplest form, a raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature.
