Create observer points

This is the first step for the visibility analysis. The result will be written as a shapefile with standardised field name.

Input

All input parameters are stored in the accompanying table and can be changed manually. Field names need to remain as assigned.

Observer/target height and radius of analisis can be read from shapefile’s data table for each view-point (a valid table field has to be chosen in the dropdown list). In case of error (eg. an empty field) the value specified in the text box will be applied.

Output

View-points will be saved as a point shapefile with chosen parameters in the accompanying table. The points can, then, be used with any elevation model provided their coordinate systems match.
