Z/I Digital Mapping Camera
Question 1
Into what general category of EOS does the instrument fall?
Multispectral and panchromatic.
Question 2
What capture technology is used?
The modular system consists of state-of-the-art components centered on frame sensor technology to enhance all aspects of the digital workflow. So it is -frame based.
Question 3
Is the sensor active or passive?
Passive
Question 4
At what wavelength(s) does the sensor function?
Multispectral Cameras: Red,Green,Blue and near infrared
Blue- 400-580nm
Green- 500-650nm
Red-590-675nm
Near infrared-675-850nm
Question 5
What resolution does the sensor have – temporal and spatial?
Temporal
N/A as the camera is only used intermittently.
Spatial
High-quality resolution at engineering-scale accuracy – supplying images with ground resolutions of less than 5 centimeters (2 inches) but dependant on flying height
Question 6
Is the sensor carried on an airborne or spaceborne platform? What is that platform – typically?
Airborne. Digital acquisition platform on-board the aircraft.
Question 7
Who developed/launched/manages the sensor?
Intergraph Corporation with Carl Zeiss
Question 8
Can data be purchased from service providers?
Yes, many mapping firms have purchased the ZI DMC. Customers can be commercial and government based. Examples of a mapping firm is Digital Mapping Inc.-west coast Huntington beach Ca.-it specialises in photgrammetric mapping and aerial photographic applications services. Source Intergraph
Question 9
What products are available?
Initially mall-scale or large-scale images. It can produce from small-scale orthophotos to large scale engineering mapping products to multispecral products for remote sensing applications.
Question 10
At which main application areas is the sensor aimed?
It is used for small scale and large scale mapping and image analysis and engineering applications, including agriculture cadastral mapping, environmental studies, natural hazard assessment, flood risk management, transportation engineering, urban planning, civil engineering, oil and gas exploration and geology. It can produce from small-scale orthophotos to large scale engineering mapping products to multispectral products for remote sensing applications.
List 2 specific projects, where they have been reported, their goals and their outcomes.
An example would be The Florida Department of transportation surveying and mapping office. Before and after images of the Eglin Air force Base NCO/Officers Beach Club, Florida, were captured using a DMC system and highlight the damage done to the facility by hurricane Ivan.
