Laser scanners are being deployed on many engineering projects to produce accurate and complete as-built point clouds.
Multispectral scanners (MSS) are sensors that detect emitted and reflected energy electrically, rather than photographically, with the electric signal being converted to digital form for image processing and interpretation.
Multispectral scanners can image from UV through the thermal IR band. The Near Infrared portion of the EM (.7 1.3 micrometers) is sensitive to leaf structure. The greatest amount of EM energy reflected the plants is in the Near IR.
Three types of scanners are available. Flat-bed scanners have a flat scanning surface on which a map or a photograph is placed. Small flat-bed scanners (20 X 30 cm.) cost

Smaller-format scanners can also be used to create raster files of documents such as permit forms, service cards, site photographs, etc. These documents can be indexed in a relational database by number, type, date, engineering drawings, etc.
The Multi-Spectral-Scanner had a 9" fused silica dinner-plate mirror epoxy bonded to three invar tangent bars mounted to base of a Ni/ Au brazed Invar frame in a serreuire truss that was arranged with four "Hobbs-Links" (conceived by Dr. Gregg Hobbs) ...

Electronic scanners record blemishes on a map just as faithfully as they record the map features. For example, a fleck of dirt might connect two lines that should not be connected.
Landsat uses two types of sensors to monitor the Earth: Thematic Mapper and Multispectral Scanner. See the following website for more information - Landsat Program.
Satellite images may be produced photographically or by on-board scanners (e.g., MSS). scale See map scale. scale bar A map element that shows the map scale graphically.
(DPI is used to express printer and scanner resolution). A pixel is the basic unit of measurement in computer screen resolution and is also, the smallest unit constituting a bitmap (raster) image.
Scanning the raster data: High resolution scanners give very accurate raster images from the hard copies, which can be georeferenced, and digitized to get the vector output.
Mobile software for Pocket PC and can be upgraded to include a high-speed linear image scanner to read bar codes. The 750 be model runs on a Lithium-Ion, 3.6V (1 x 2400 mAh cell) battery.
Tools such as these can manipulate output from high (over 3000 pixels per inch) resolution drum scanners, as well as the output from a desktop flatbed scanner.

Actually, it is a complex technology beginning with the digital representation of landscapes ca ptured by cameras, digitizers, or scanners, in some cases transmitted by satellite, and, with the help of computer systems, stored, checked, manipulated, ...
Sensors include cameras, digital scanners and LIDAR, while platforms usually consist of aircraft and satellites.
Document scanning involves using scanners to capture a digital image of a map, manuscript, or other document. Once the image is stored, a variety of processes can be applied, depending on the image's intended use.
Hardware vendors continued to improve digitizing equipment, with manual digitizing tablets giving way to automated scanners at many GIS facilities.
This can be accomplished either manually or by use of a scanner. To encode map features as x,y coordinates in digital form. Lines are traced to define their shapes. This can be accomplished either manually or by use of a scanner.
Peripherals are items of computer equipment such as plotters, printers, scanners, digitizers, and graphics displays.

Satellite Image - a picture of the earth taken from an earth-orbital satellite. Satellite images may be produced photographically or by on-board scanners (e.g., MSS).
digitize: To encode map features as x,y coordinates in digital form. Lines are traced to define their shapes. This can be accomplished either manually or by use of a scanner.
Maps can be digitized by hand-tracing with a computer mouse on the screen or on a digitizing tablet to collect the coordinates of features. Electronic scanners can also convert maps to digits (fig. 7).

mapping services using the latest in airborne technology. TopoBird provides high-resolution multispectral imagery and extremely accurate elevation data using an aircraft-mounted multi-spectral image sensor working in tandem with a LIDAR scanner.
These five inputs are used to register the image file to the scanner and to the sensor platform, to determine the orientation and location of the sensor platform with respect to the ground, and to remove the relief displacement from the image data.
Data dictionaries can be created for ease of use and flexibility. Data dictionaries can use text that can either be typed in or selected as menu choices. Certain GPS data loggers can also use bar-code scanners for data entry.
