Global Mapper is a geographic information system (GIS) software package currently developed by Blue Marble Geographics [1] that runs on Microsoft Windows. The GIS software competes with ESRI , GeoMedia , Manifold System , and MapInfo GIS products.
Blue Marble's first software product, the Geographic Calculator, [2] was developed in 1992 and released in 1993. The Geographic Calculator is a coordinate conversion library with a database of coordinate mathematical objects including projections, coordinate systems, datums, ellipsoids, linear and angular units.
MAPPER Systems, now known as Business Information Server, BIS, is a fourth-generation programming language originally from Sperry Univac. Now owned by Unisys Corporation. Mapper originated in the 1970s [1] based on some work in the 1960s, [2] It has been functionally enhanced and kept current. It was also given an extension named ICE - Internet ...
Both 32-bit and 64-bit versions of these operating systems are supported, except for Windows IA-64 (not supported) and Mac OS X 10.6 Snow Leopard (runs as a 32-bit process). [24] The version for Windows 7, Windows Vista, and Windows XP can encrypt the boot partition or entire boot drive.
The Global Positioning System (GPS) broadcasts a date, including a week number counter that is stored in only ten binary digits, whose range is therefore 0–1,023. After 1,023, an integer overflow causes the internal value to roll over, changing to zero again. Software that is not coded to anticipate the rollover to zero may stop working or ...
Citymapper is a public transit app and mapping service [4] [5] which displays transport options, usually with live timing, between any two locations in a supported city. It integrates data for all urban modes of transport, including walking, cycling and driving, in addition to public transport. [6]
A Data Mapper is a Data Access Layer that performs bidirectional transfer of data between a persistent data store (often a relational database) and an in-memory data representation (the domain layer). The goal of the pattern is to keep the in-memory representation and the persistent data store independent of each other and the data mapper itself.
The upper photo on the right is a 50 times magnification of the combined photomasks used to fabricate the Hughes H4040, the linear silicon photodiode array used in the Thematic Mapper to image the visible bands. Each of the 16 photodiodes is 100 microns square and their separation is 100 microns. There are two rows because it is scanned ...
