  • 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...

  • Unit Testing for Esri Developers - GIS Mapping Software

    Designing Arcobjects Applications and Complex Testing ScenariosUnit Testing Geometry Operations: A Test Case For ArcunitUsing ArcunitConclusionAbout The AuthorsSimple methods with simple arguments mean simple unit test fixtures. Nearly everyone reading this article will understand that testing a summing function, a user authentication routine, or a method to fetch data is a relatively straightforward process. At the same time, testing complex methods that accept complex inputs results in complex test fixtures with results that are frequently difficult to reduce to a Boolean good or bad result. While the authors work primarily in the Web realm on a daily basis, we have written literally hundreds of thousands of lines of ArcObjects code over the years and recognize the integral role such applications will continue to play in the GIS enterprise for the foreseeable future. Unit testing these applications is critical. Most ArcObjects code falls into the second, more complex, testing category. For example, how does the developer test that a custom edit sketch task returned a valid geometry or that the resulting geometry intersected with a target...

  • Spatial Analysis - GIS Wiki | The GIS Encyclopedia

    The History of Spatial AnalysisFundamental Issues in Spatial AnalysisTypes of Spatial AnalysisGeographic Information Science and Spatial AnalysisSee AlsoFurther ReadingExternal LinksSpatial analysis could be considered to have arisen with the early attempts at cartography and surveying but many fields have contributed to its rise in modern form. For example, biology contributed through botanical studies of global plant distributions and local plant locations, ethological studies of animal movement, ecological studies of vegetation blocks, ecological studies of spatial population dynamics, and the study of biogeography. Epidemiology contributed with early work on disease mapping, notably John Snowwork mapping an outbreak of cholera, with research on mapping the spread of disease and with locational studies for health care delivery. Statistics has contributed greatly through work in spatial statistics. Economics has contributed notably through spatial econometrics. Modern spatial analysis focuses on computer based techniques. Because of the large amount of data, the power of modern statistical and geographic information science (GIS) software, and the complexi...

  • Modifiable areal unit problem - GIS Wiki | The GIS Encyclopedia

    BackgroundSuggested SolutionsMaup Sensitivity AnalysisExamplesReferencesThe issue was discovered in 1934, but the term MAUP was first coined and described in detail by Openshaw, who lamented that "the areal units (zonal objects) used in many geographical studies are arbitrary, modifiable, and subject to the whims and fancies of whoever is doing, or did, the aggregating". The problem is especially apparent when the aggregate data are used for cluster analysis for spatial epidemiology, spatial statistics or choropleth mapping, in which misinterpretations can easily be made without realizing it. Many fields of science, especially human geography are prone to disregard the MAUP when drawing inferences from statistics based on aggregated data. MAUP is closely related to the topic of ecological fallacyand ecological bias. Ecological bias caused by MAUP has been documented as two separate effects that usually occur simultaneously during the analysis of aggregated data. The scale effect causes variation in statistical results between different levels of aggrega...
