Is PNG a raster format?
A PNG is a raster — that is, pixel-based — image format. If you scale up a raster image too far, it becomes grainy and pixelated. Similarly, if the image is too small, it can become indistinct. While PNGs are capable of handling very high resolutions, they're not infinitely expandable.

Its features include indexed color images of up to 256 colors and effective 100 percent lossless images of up to 16 bits per pixel.#N#Single file—extension *.png#N#Joint Photographic Experts Group (JPEG2000)#N#Open-source raster format. A compressed format, allows both lossy and lossless compression. JPEG 2000 is a non-proprietary image compression format based on ISO standards, and typically uses .jp2 as the file extension. It’s advantages are that it offers lossy and lossless compression, and world files (.j2w) can be used to georeference an image in GIS software.

A compressed wavelet format, allows both lossy and lossless compression. MrSID is a proprietary format of LizardTech’s GeoExpress software for imagery compression, and is commonly used on orthoimages. The MrSID file extension is .sid. A companion file with a .sdw extension and the same prefix name as the .sid is used as a world file for georeferencing a MrSID image.#N#Most greyscale TIFF images are compressed with MrSID to 10:1 or 15:1. Color images are usually compressed to 30:1 or 40:1. GeoExpress is also commonly used to create image mosaics.#N#Most recent GIS software, including ArcGIS, are able to read MrSID compressed images without any additional extensions.

What is an arcinfo grid?
An ArcInfo Grid does not have an individual file extension. Instead it is composed of two folders within a “workspace” which each contain multiple files. One of the two folders carries the name of the grid, and contains a number of various .adf files. The other folder is an “info” folder, which typically contains .dat and .nit files for all the coverages and grids in the workspace. The best way to manage (copy, move, delete, rename) ArcInfo Grids is with ArcCatalog or ArcInfo Workstation (command line).

Digital Raster Graphic is a raster file format. From scanning a paper USGS topographic map for use on a computer a digital image is created called DRGs. The DRGs which are created by USGS are typically scanned at 250 dpi and then the DRGs are saved as a TIFF file in the server. The Raster data image usually includes the original border information, referred to as the “map collar”. The raster map file is projected by UTM and georeferenced to the surface of the earth.

What is raster image?
Raster, or bitmap, images consist of tiny squares called pixels. These pixels contain bits of color and when combined, they build images. The more pixels in an image the higher the quality, and vice versa. When you zoom in on an image the pixels become more apparent while the details of the image become blurry.
