| Algorithm |
| Default |
A
cell-based algorithm. It is faster than the Follow method,
but does not allow contour labelling. |
| Follow |
A
contour-line based algorithm. This method is slower, but looks better
with dashed line styles. Also, it allows contour labelling which
the default method does not. |
|
| Fill |
Toggle
specifying whether or not to color fill the contour levels. List
the fill colors to be used in the field Graphics palette.
Separate each with a comma. |
| Data
source |
Specify
whether to contour the raw or geophysical data. |
| Data
ignored (Geo or Raw unit) |
| Equal
or above |
Pixel
values (in Geo or Raw units) equal to or above this value are ignored (treated
as missing data) when contouring. |
| Less
than |
Pixel
values (in Geo or Raw units) less than this value are ignored (treated
as missing data) when contouring. |
|
| Option
of contour level |
| Equally
spaced |
Equally
space the contour levels, based on
Number of equally spaced contour
levels. |
| User-specified |
Provide
a customized list of contour levels in field User specified contour
levels. Separate each entry with a comma. |
|
| Number
of equally spaced contour level |
Enter
the number of contour levels desired. |
| User
specified contour level |
Enter
a customized list of contour levels. Separate with commas. |
| Parameters
for each contour level |
| Annotation |
Enter
a list of annotations for each level. Separate values with commas.
Annotation capability is only provided with the Follow algorithm. |
| Graphics
palette |
Enter
a list of graphics palette colors (1 to 7) for each contour level.
These colors will apply to either the contour lines or the contour fill
colors. Separate with commas. |
| Line
thickness |
Enter
a list of line thicknesses for each contour level. Separate with
commas. |
| Line
style |
Enter
