Why Use Glance?

|
|
Glance does all the work involved in providing you with complex, carefully controlled comparisons. In can give you a report proving whether your data sets are as similar as you need them to be for validation. If there are differences between your data sets, Glance makes them simple to spot and easy for you to analyze.

Glance has many features which make comparing two dissimilar data files painless for you. It can take different file types, different corresponding variable names from each file, arbitrary data filters that can be used to correct for differing data types (such as int vs. float) or pixel-wise shifted data. Glance also handles any standard data scaling recorded in the source files automatically, so that differences in scale constants between files won't get in the way of your comparison. Wherever possible Glance insures that you will not need to pre-process your data manually before comparing it.

When you ask Glance to create reports or plots with your data navigated on the Earth, it will also automatically detect dissimilarities in longitude and latitude and alert you if there are possible problems in the spatial placement of your two data sets relative to each other. This can catch positional differences that might otherwise be attributed to an algorithm problem if the data was compared pixel-wise.
