Data logger Cube storing technical and sensor data. A data logger (also datalogger or data recorder) is an electronic device that records data over time or about location either with a built-in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer), and ...
An image retrieval system is a computer system used for browsing, searching and retrieving images from a large database of digital images. Most traditional and common methods of image retrieval utilize some method of adding metadata such as captioning, keywords, title or descriptions to the images so that retrieval can be performed over the annotation words.
Each image tile covers a 3.75 x 3.75 minute quarter quadrangle plus a 300-meter buffer on all four sides. CCMs are generated by compressing DOQQ image tiles into a single mosaic. All individual tile images and the resulting mosaic are rectified in the UTM coordinate system , NAD 83 , and cast into a single predetermined UTM zone.
Multiple replicate shipments of data loggers are also used to compare modes of shipment (routes, vendors) and to develop composite data to be used in package testing protocols. [9] There are many brands and models of data loggers. Most are a connectable device that must be plugged into a computer to extract the data that the logger has logged.
The software mainly consists of a number of command-line interface utilities for manipulating images. ImageMagick does not have a robust graphical user interface to edit images as do Adobe Photoshop and GIMP, but does include – for Unix-like operating systems – a basic native X Window GUI (called IMDisplay) for rendering and manipulating images and API libraries for many programming languages.
A data storage tag (DST), also sometimes known as an archival tag, is a combination of a data logger and multiple sensors that record data at predetermined intervals. DSTs usually have a large memory size and a long lifetime: most are supported by batteries that allow the tag to record positions for several years.
There are occasional edge cases where only one of the FSF or the OSI accept a license, but the popular free software licenses are open source, including the GPL. [72] Mitchell Baker drafted the Mozilla Public License while on Netscape's legal team. [73] Practical benefits to copyleft licenses have attracted commercial developers.
Many of the techniques of digital image processing, or digital picture processing as it often was called, were developed in the 1960s, at Bell Laboratories, the Jet Propulsion Laboratory, Massachusetts Institute of Technology, University of Maryland, and a few other research facilities, with application to satellite imagery, wire-photo standards conversion, medical imaging, videophone ...
