Lecture

Isovalues: Applications and Creation

Description

This lecture covers the common use of isovalue curves in various applications, such as relief visualization with contour lines and meteorology with isobars, isohyets, and isotherms. The creation of isolines through linear interpolation on grids of measured or interpolated values is explained, with a practical demonstration using the 'contour creation' function in the 'raster' menu of QGIS software. The lecture concludes the discussion on continuous spatial phenomena, paving the way for the exploration of numerical altitude models in the upcoming week.
