Satellite Imagery
The rapid growth of the field of remote sensing has greatly contributed to our understanding of earth processes and the technology required to monitor them.
As many of you may remember, the distribution of IKONOS imagery was subsequently supressed during the Afghanistan war when the United States government bought up all of the IKONOS overflight capacity for the duration.
imagery - A graphical representation of an object produced by an optical or electronic device (photograph).
imagery Visible representation of objects and (or) phenomena as sensed or detected by cameras, infrared and multispectral scanners, radar, and photometers.
Imagery - A two dimensional digital representation of the earth's surface. Examples are a digital aerial photograph, a satellite scene, or an airborne radar scan.

NMEA
National Marine Electronics Association; The NMEA 0183 protocol is a means by which marine instruments and also most GPS receivers can communicate with each other.
Satellite imagery is always in raster format, where each pixel has its own signature. While ArcGIS can manipulate raster data, it is better to use a dedicated raster program such as Erdas Imagine.
Geometric imagery is not just something that you are either born with or you are not. Like any other skill, it develops with practice.

I ordered the Imagery from NASA, and it came in about 2 weeks. The CD comes with a README.PDF and there is also a Data Descriptor file for IMG70.dda and a image metadata file, IMG70_1.TXT of the images.
Satellite Imagery: Digital data obtained from sensors carried in satellites. It includes collecting data both in the visible and non-visible portions of the electromagnetic spectrum.
remotely sensed imagery data can be interpreted to yield many layers

[edit] Uses of imagery
Aerial photography is used in cartography (particularly in photogrammetric surveys, which are often the basis for topographic maps), land-use planning, archaeology, movie production, environmental studies, surveillance, ...
The National Imagery and Mapping Agency's (NIMA's) geodetic survey division maintains US Army topographic surveyors as part of their survey force structure.
Landsat satellite imagery and BIL information are used in RS Landsat. In one format, using BIL, pixel values from each band are pulled out and combined. Programs that use this kind of information include IDRISI, GRASS, and MapFactory.
NIMA, The National Imagery and Mapping Agency
has been incorporated the Defense Mapping Agency as of October 1, 1996 and is also a source of considerable cartographic software and information.
Panchromatic - Imagery Single-band or monochrome imagery (TWS).
Pixel- Pixel element. The smallest resolution unit (NCRST).
Platform - Where a sensor is based, i.e., a satellite, aircraft, or other flying object (NCRST).

Satellite imagery such as Landsat TM and SPOT provide multispectral images of the earth, some containing seven or more bands.
Photogrammetry The science of using aerial photographs and other remote sensing imagery to obtain measurements of natural and human-made features on the Earth. Photoperiod The duration of the daylight period.
imagery A common way of collecting information associated with a coverage, by which the value of a continuous phenomenon is usually sampled at regular but discrete locations, i.e. pixels.
For raster imagery, a layer can represent one sensor in a multispectral array. In some cases, a layer may contain a coverage, hence provide an attribute value at all locations.

It was anticipated that analysis of Landsat satellite imagery would be a key ingredient for identifying detailed impacts from the disturbed, abandoned lands. However, an interesting turn of events made the project much more difficult than expected.
Colour management is a major concern in the distribution of digital imagery, on the Internet and in the graphic arts industry, right up to and including the printing stage.

On the desktop, ESRI's ArcView allows the integration of aerial imagery in a manner similar to workstation- based ArcInfo.
The first was created by the NIMA (National Imagery and Mapping Agency - USA), and the other was made by the Hungarian Military Mapping Agency (MH TATI).
Most often, image data is used to store remotely sensed imagery, e.g. satellite scenes or orthophotos, or ancillary graphics such as photographs, scanned plan documents, etc.
When high resolution satellite imagery become more affordable and easily accessible, we will be seeing more use of them to create GIS data layers and update existing map data.
With the wide availability of ortho-rectified imagery (both from satellite and aerial sources), heads-up digitizing is becoming the main avenue through which geographic data is extracted.
