Import of catchment basins from SRTM

The SRTM application allows creating the digital model of the ground in an area of interest identifiable through a selection box made up 4 pointes (the vertices of a rectangle).

The ASCII file generated by SRTM contains the coordinates x, y and z, separated by “;”, relevant to the pints included in the area under examination.

The ASCII file can be worked out using specially dedicated programmes, such as TRISPACE, in order to obtain relief maps, contour lines, sections, etc.

TRISPACE allows importing the file worked out by SRTM, with Importa file dati/Import data file control from the Dati/Data menu.

The imported file only contains the coordinates of the points: the identification of the basin must consequently be carried out manually.
