In John Snow determined the source of a cholera outbreak in London by marking points on Thesis reverse logistics map depicting where the cholera victims lived, and connecting the cluster that he found with a nearby water source. This was one of the earliest successful uses of a geographic methodology in epidemiology.

While the basic elements of topography and theme existed previously in cartographythe John Snow map was unique, using cartographic methods not only to depict but also to analyze clusters of geographically dependent phenomena.

This work was originally drawn on glass plates but later plastic film was introduced, with the advantages of being lighter, using less storage space and being less brittle, among others. When all the layers were finished, they were combined into one image using a large process camera.

Once color printing came in, the layers idea was also used for creating separate printing plates for each color. Computer hardware development spurred by nuclear weapon research led to general-purpose computer "mapping" applications by the early s.

A rating classification factor was also added to permit analysis. It supported a national coordinate system that spanned Thesis reverse logistics continent, coded lines as arcs having a true embedded topology and it stored the attribute and locational information in separate files.

As a result of this, Tomlinson has become known as the "father of GIS", particularly for his use of overlays in promoting the spatial analysis of convergent geographic data. It was developed as a mainframe -based system in support of federal and provincial resource planning and management.

Its strength was continent-wide analysis of complex datasets. The CGIS was never available commercially. This was renamed in to MapInfo for Windows when it was ported to the Microsoft Windows platform.

This began the process of moving GIS from the research department into the business environment. More recently, a growing number of free, open-source GIS packages run on a range of operating systems and can be customized to perform specific tasks. The most common method of data creation is digitizationwhere a hard copy map or survey plan is transferred into a digital medium through the use of a CAD program, and geo-referencing capabilities.

With the wide availability of ortho-rectified imagery from satellites, aircraft, Helikites and UAVsheads-up digitizing is becoming the main avenue through which geographic data is extracted. Heads-up digitizing involves the tracing of geographic data directly on top of the aerial imagery instead of by the traditional method of tracing the geographic form on a separate digitizing tablet heads-down digitizing.

Just as a relational database containing text or numbers can relate many different tables using common key index variables, GIS can relate otherwise unrelated information by using location as the key index variable. Any variable that can be located spatially, and increasingly also temporally, can be referenced using a GIS.

Units applied to recorded temporal-spatial data can vary widely even when using exactly the same data, see map projectionsbut all Earth-based spatial—temporal location and extent references should, ideally, be relatable to one another and ultimately to a "real" physical location or extent in space—time.

Related by accurate spatial information, an incredible variety of real-world and projected past or future data can be analyzed, interpreted and represented. GIS uncertainties[ edit ] GIS accuracy depends upon source data, and how it is encoded to be data referenced.

Land surveyors have been able to provide a high level of positional accuracy utilizing the GPS -derived positions. In developing a digital topographic database for a GIS, topographical maps are the main source, and aerial photography and satellite imagery are extra sources for collecting data and identifying attributes which can be mapped in layers over a location facsimile of scale.

A quantitative analysis of maps brings accuracy issues into focus. The electronic and other equipment used to make measurements for GIS is far more precise than the machines of conventional map analysis.

GIS file formats GIS data represents real objects such as roads, land use, elevation, trees, waterways, etc. Real objects can be divided into two abstractions: Traditionally, there are two broad methods used to store data in a GIS for both kinds of abstractions mapping references: Points, lines, and polygons are the stuff of mapped location attribute references.

A new hybrid method of storing data is that of identifying point clouds, which combine three-dimensional points with RGB information at each point, returning a " 3D color image ".

GIS thematic maps then are becoming more and more realistically visually descriptive of what they set out to show or determine. Data capture[ edit ] Example of hardware for mapping GPS and laser rangefinder and data collection rugged computer.

The current trend for geographical information system GIS is that accurate mapping and data analysis are completed while in the field. Depicted hardware field-map technology is used mainly for forest inventoriesmonitoring and mapping. There are a variety of methods used to enter data into a GIS where it is stored in a digital format.

A digitizer produces vector data as an operator traces points, lines, and polygon boundaries from a map. Scanning a map results in raster data that could be further processed to produce vector data.

Survey data can be directly entered into a GIS from digital data collection systems on survey instruments using a technique called coordinate geometry COGO. A current trend in data collection gives users the ability to utilize field computers with the ability to edit live data using wireless connections or disconnected editing sessions.

But now it's time to decide between merely managing returns more effectively and rethinking reverse logistics' role as a supply chain strategy.
