Assessment and Predictive Maps

Thematic mapping traditionally distinguishes two main areas for practical application - assessment and predictive mapping.

In creating the assessment maps, experts in satellite imagery interpretation expand the characteristics of the phenomena mapped and translate them into the applied aspect. Spatial information obtained in thematic assessment classification describes the territory in terms of its economic importance and practical benefits. For example, a forest block can have both a thematic map showing the stand species composition, and the thematic map of forest available for wood supply, which will take into account not only the diversity of species, but also the age of forests, logging criteria, terrain tilt angles and other factors.

Thus, the assessment mapping is multivariable. With this approach, in accordance with the task set, SCANEX experts first determine a set of assessment criteria for mapping, and then perform a detailed interpretation, based on which the final assessment map is drafted.

Sample assessment maps:

The creation of predictive maps is based on the principles of expert mathematical and cartographic modelling. In predictive mapping, the principle of space-time certainty is retained. For predictive mapping, SCANEX experts study the historical data, on the basis of which it is possible to build predictive models.

Sample predictive maps:

In assessment and predictive mapping, SCANEX experts apply multiparameter classification methods and algorithms implemented on the basis of ScanEx Image Processor software, as well as conducting the visual interpretation of multispectral satellite imagery. These types of expert mapping are implemented after the detailed study of the problems and the peculiarities of the phenomenon are mapped.
