resolution: the number of distinct pixels that can be displayed in a measured space.raster: datasets defined as an array of pixels.pixel: a portmanteau of ‘picture element’, the smallest unit of a raster.lossy: compression that results in data loss.lossless: compression that does not result in the loss of data.LIDAR: Light Detection and Ranging, a technology for collecting data using laser reflectance.gamut: a subset of colors in a color model representable in a color space.dithering: a technique for minimizing content loss during reduction of color depth by inserting pixel noise.color space: a definition of colors in a color model which allows for repeatable reproduction of color.color model: a mathematical model for representing colors such as RGB or CMYK.bit depth: the number of bits storable for a given data type.bit: a portmanteau of binary digit, the smallest unit of storable information.
bands: a defined channel or subset of a raster dataset, for instance, the red channel of an RGB image.anti-aliasing: an approach to minimizing visual artifacts caused by fitting vector graphics into a grid of pixels.alpha channel: a raster band used for transparency compositing that allows for blending of pixel content with digital content conceptually beneath the raster dataset.
