Lineaments - DTM Grid Generation
This module allows a Digital Terrain Model generation, using a regular grid
representation, with values proportional to the lineaments quantity and size, in
an active IL, crossing each grid element. The Information Layer selected (active IL)
has to have lineaments, lines vectorial representation. An IL of a numerical category
is created using a regular grid representation. For each element of the regular grid
the program computes a value, proportional to the size and quantity of lineaments crossing
the element.
Executing the Lineaments DTM
Generation:
- activate in the "Control Panel" the IL,
in the Thematic, Cadastral or Numerical model, that has the lineaments;
- click on Analysis - Lineaments - DTM Generation...;
- in the "DTM Generation" window,
- Select, as input, Frequency or Density.
- Next, the user has to select a Category already defined in the data base,
type a name for the IL Name which has the output numerical grid.
The category has to exist and has to belong to the numerical model. Otherwise
create a new category using the Data Model option in the File
menu.
- Next, the user has to define an involving rectangle, the X and Y resolution and the number of bits
for the DTM grid which will be generated by the program, the bits value for the grid can be 32 or 64 bits.
- Finally, the user has to press the apply button so the frequency or density
grid will be generated.
