COMPARISON OF QGIS INTERPOLATION MODULES CAPABILITIES FOR MARINE CLIMATE RESEARCH ON DUTY WITH AN ARRAY OF LOW-SECURITY DATA

Abstract

In the article the urgency of modern methods’ active use in oceanographic data spatial analysis from the perspective of geo-information and geostatistical approaches is approved. There are analyzed the possibilities of some open GIS QGIS statistical modules for practical problems of data quality rapid assessment solution. The quality of QGIS interpolation modules is estimated representing methods of kriging and radial basis functions (splines) by using an array of low-security data.
