Image Services

An image service provides read-only access to a mosaicked collection of images or a raster dataset.   

Use an image service to:

• Query image service information, including its native spatial reference, extent, pixel size, pixel type, number of bands, and band statistics

• Fetch pixels for a given image description, containing cellsize, spatial reference, extent, band selection, mosaic method, and view point properties

• Generate a dynamic image (view)

Image pixels are returned in a byte array and arranged in a band interleaved by pixel format plus a NoData mask. The byte array can be optionally compressed using JPEG (plus transparency), and LZ77 compression. Create a dynamic image by exporting into a well-known format and returning it as MIME data, or a URL. The supported well-known image format includes JPEG (plus transparency mask), PNG, BMP, and TIFF.
