iMOD User Manual version 4.4 (html)


9.22SPF-files

A SPF-file describes the variation in the top and bottom elevation along a cross-sectional line. Each SPF-file can be alternated individually within iMOD or within regular text editors, such as NotePad. The latter is not recommended however.

NCRD

Number of coordinates that describe the cross-sectional line.

X{i},Y{i}

Enter NCRD number of coordinates X and Y.

TotLength

Total length of the cross-section. This is used (and updated whenever the coordinates X and Y are adjusted inside and/or outside iMOD) to avoid any adjustments of the elevations outside the outer limit of the cross-sectional line.

NP{i},Clr{i},Lt{i}

Number of alternations of the top (i =uneven) or bottom (i =even) elevations. Clr{i} and Lt{i} are the linecolour (colour number for a colourdisplay of 16 million colours; 255=red) and linethickness (between 1 and 10) of the i\({}^{th}\) top or bottom IDF as mentioned in the SOL-file that directs to this SPF-file.

x{i},z{i}

The distance from the first coordinate (X1,Y1) of the cross-sectional line, followed by the vertical position of the elevation (top or bottom).

x\(_1\),y\(_1\),x\(_2\),y\(_2\),bitmap

On the last line of the SPF file it is possible to add a bitmap (*.jpg, *.bmp or *.png) that need to be attached to the cross-section. Specify the position of the bitmap by the x\(_1\),y\(_1\),x\(_2\),y\(_2\) variables. Note: Be aware that iMOD uses the upper-left corner as \(x_1,y_1\) and the lower-right corner as \(x_2,y_2\).
