GIS analysis, terrain modeling and analysis

Within geographic information systems (GIS), analysis corresponds to the set of methodologies or processes for the extraction or creation of new information leading from a query, modeling exercise, or interpretation of existing information.

SIG

The principal objectives can be a better understanding of the information, the establishment of certain relationships and modeling between georeferenced variables, and aid in evaluating and predicting new scenarios. 

GIS analysis 
  • Map algebra procedures 
  • Layer superposition 
  • Multicriteria analysis
  • Proximity relationships
  • Attribute transfer
  • Spatial interpolation
  • Correlations and autocorrelations
  • Error propagation

Terrain analysis

Terrain analysis specifically means a study derived from altimetric information, be it directly (using relief, slope, or orientation information) or with interaction with other variables such as climate models. 
CREAF has hosted the development of its own models in some of these areas, initially as very specialized tools in the context of an academic thesis or R+D project, such as a model for radiometric correction for remote sensing images or a hybrid methodology of multiple regression and spatial interpolation, for later completion and integration into the MiraMon GIS. It is also worth noting that the study of imprecisions in measurements of area and distance in certain cartographic projections have given way to contributions of solutions of a higher geodesic rigor which have also been implemented in the corresponding MiraMon GIS tools.
