Picture elements
Picture elements are graphics files that can be added to a layout. Most common graphics file formats can be used to create picture elements.

pixel. picture element; a tiny dot in a digital image composed of a set of such dots

Pixel One picture element of a uniform raster or grid file. Often used synonymously with cell.
Pixel: One picture element. Often used synonymously with a raster or grid cell. The smallest discrete element which makes up an image.
Planimetric: In mapping, refers to spatial data that do not include topographic or relief data.
The concept of a "picture element" dates to the earliest days of television, for example as "Bildpunkt" (the German word for pixel, literally picture point) in the 1888 German patent of Paul Nipkow.
A raster display builds an image from pixels, small square picture elements of coarse or fine resolution. A raster database maintains a "picture" of reality in which each cell records some sort of information averaged over the cell`s area.
picture element-In a digitized image, the area on the ground represented by each digital number. Commonly contracted to pixel.
For example, a raster image is composed of thousands of 'pixels' (picture elements) that are analogous to the dots on a computer screen.
raster Data displayed as discrete picture elements (pixels).
relate An operation that establishes a temporary connection between corresponding records in two tables using an item common to both.
The most common use of the term resolution refers to the area on the ground represented by one cell or pixel (picture element) of a raster-based system.
as an array or grid of pixels (picture elements). Each pixel has an x,y coordinate defining its position on a display surface (computer monitor). Values describing its colour, based on the RGB colour model are also stored at each pixel.
A contraction of the words picture element. The smallest unit of information in a raster based format. A grid cell.
Point
A feature class which represents a specific x,y coordinate.
Pixel: Abbreviation for Picture Element, the smallest nondivisible image-forming unit of a plot or video display. Each cell can have assigned attributes, in addition to color.
digital image -- a two-dimensional array of regularly spaced picture elements (pixels) constituting a picture.
digital volume -- a three-dimensional array of regularly spaced volume elements (voxels) constituting a volume.
Pixel - A term derived from "picture element", which is the smallest unit of resolution in data storage and display.

The accompanying Landsat Thematic Mapper image shows a false-color infrared image of the same area in 30-meter pixels, or picture elements.
as colour and intensity. 2) In remote sensing, refers to the fundamental unit of data collection. A pixel is represented in a remotely sensed image as a rectangular cell in an array of data values. The term is an abbreviation for 'picture element'.
Contraction of picture element. planar graph p. 37 an arrangement of nodes and lines such that the lines intersect only at nodes, thus remaining embedded in a plane (or a surface topologically transformable onto a plane). point-in-polygon p.
