  • 3 specific features of GIS software testing you need to be

    Testing Vast Amounts of Diverse DataTesting with Real Or Pre-Modified DataTesting The Variety of GIS SoftwareWhat Makes Proper GIS App Testing?GIS applications allow visualizing data through mapping, which means there are both data itself and a map that presents it. In other words, GIS databases store both spatial coordinates and attribute data such as roads, buildings, businesses, and other objects. This is probably the major peculiarity of GIS software testing: a QA engineer should be attentive to the accuracy of figures and the right object positioning alike. Regarding the spatial data accuracy, it’s crucial to debug all the controversies between the encoded location of the map items and their actual positioning. Moreover, certain GIS software may be compiled from multiple map sources, so there can be conflicts between them, too: a few overlapping layers is a typical example. Attribute data such as street names or any statistics to be displayed is another aspect requiring a testing engineer’s thorough consideration. If a GIS app contains erroneous attribute data, bugs might appear in its visualization—for instance, stre...

    The Importance of Error, Accuracy, and PrecisionSome Basic DefinitionsTypes of ErrorSources of Inaccuracy and ImprecisionThe Problems of Propagation and CascadingBeware of False Precision and False Accuracy!The Dangers of Undocumented DataUntil quite recently, people involved in developing and using GIS paid little attention to the problems caused by error, inaccuracy, and imprecision in spatial datasets. Certainly, there was an awareness that all data suffers from inaccuracy and imprecision, but the effects on GIS problems and solutions was not considered in great detail. Major introductions to the field such as C. Dana TomlinGeographic Information Systems and Cartographic Modeling (1990), Jeffrey Star and John EstesGeographic Information Systems: An Introduction (1990), and Keith ClarkeAnalytical and Computer Cartography(1990) barely mention the issue. This situation has changed substantially in recent years. It is now generally recognized that error, inaccuracy, and imprecision can "make or break" many types of GIS projects. That is, errors left unchecked can make the results of a GIS analysis almost worthless. The irony is that the problem of error is it devolves from one of the greatest strengths of GIS...

Fuel EfficiencyUpdate Aug. 18, 2018Air pollution and carbon emissions in China have mainly been attributable to coal burning and industrial production during the early stage of economic development. In urban areas, especially megacities such as Beijing and Shanghai, emissions from vehicles have become an increasing problem.In recent years, it has been observed that the emissions of long-regulated sulfur dioxide (SO2) and total suspended particulates (TSP, including particulate matter [PM10]), have passed their peak and are diminishing. The situation of fine particulate matter (PM2.5) and ground-level ozone (O3) concentration, however, is worsening. Regional air pollution problems are becoming significant. Sometimes vast regions, such as all of eastern and central China, are under very high concentrations of PM2.5 and O3.
