advantages of SF6-Air leak testing for gis

The cordless battery-operated LEAKSPY SF6 precisely measures SF 6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppm v. The device allows precise localisation of leaks by searching the highest SF 6 concentration. Thanks to the high accuracy and the low detection limit it is possible to carry out integral measurements as well as measurements for determination of leakage rates.

  • 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...
