Publishing remote sensing images
Let's look at how to publish a three-band remote sensing image.
The difference between image, image and picture concept
Visual products that are commonly referred to as satellite or other sensor devices are referred to as "RS-Image" rather than "image". The concept of "RS-Image" has a broader meaning, and "image" is a kind of "picture". The RS-Image and the image together form the image world.“Image” mainly refers to the world of reproducible images formed by photography, television, film, digital imaging, computer painting, and network imaging, and of course includes remote sensing.
"Picture" refers to a flat media composed of graphics, images, and the like. Note that the definition here is that "image" is not a kind of "picture".The picture is first of all a medium (or medium) that actually exists (can be electronic); in addition, it is still flat. "Picture" is a form of expression of "image".
Adding remote sensing images
Similar to the Mapfile structure used earlier, but need to define the remote sensing image data source:
01 MAP 02 EXTENT -180 -90 180 90 03 SIZE 600 300 04 SHAPEPATH "/gdata" 05 LAYER 06 NAME "modis" 07 DATA "land_shallow_topo_8192.tif" 08 STATUS OFF 09 TYPE RASTER 10 END 11 END
Here's the effect:
