Choosing Geological Cross-Section Drawing Software

Define the Job Before Choosing a Tool

An attractive sample drawing is not enough to evaluate geological cross-section software. Consider the data, revision frequency and intended deliverable. A two-borehole profile and a complex regional geological model are different tasks. General drafting tools offer layout flexibility; borehole-focused applications aim to reduce repetitive placement work. Test suitability against your own workflow.

1. Test Geometry with Known Values

For a vertical borehole with a +100.00 m collar and a boundary at 4.00 m depth, the boundary should be at +96.00 m. Raising the collar to +101.00 m should move that boundary to +97.00 m. Changing borehole spacing should alter horizontal placement without changing recorded depths. Check route end intervals, total length and direction labels as well.

2. Review Horizontal and Vertical Scales

Thin layers may become hard to see along a long route. Evaluate whether the display can be adjusted without altering data, and whether the exported scale remains clear. A horizontal scale of 1:500 and vertical scale of 1:100 produce fivefold vertical exaggeration. Apparent dips should not be read as true dips. Printing a PDF with fit-to-page can also alter its physical scale.

3. Examine Geological Interpretation

Try examples with an intermediate layer in only one borehole, rather than identical sequences everywhere. Similar lithology in separate boreholes does not prove continuous material between them. BGS discusses the difficulty of distinguishing local lenses from more widespread deposits. Review generated connections against the source records and geological context.

4. Test a Crowded Drawing

Combine long lithology descriptions, closely spaced boundaries, collar labels and foundation-level annotations. Can you distinguish thin layers, read the legend and determine which unit the foundation intersects? Check both PDF and PNG at the intended report size. Smaller text alone is not a sufficient remedy for poor layout.

5. Check Saving and Revision

Save a project, reopen it and compare the data and display settings. Wait for confirmation that saving completed before leaving. Examine how connection failures are reported; do not assume automatic saving or draft recovery exists. Keep issued outputs in a separate archive.

6. Evaluate JeoKesit Section with Your Own Example

Section is a browser-based workspace for route distances, boreholes, layers, geophysics and building information. A route defined with Map can be used in Section, reviewed in the preview and exported as PDF or PNG.

Start with a small dataset whose results you can check independently. Modify one value, inspect its effect and examine the output. The application supports drawing and presentation; professional geological interpretation and project-specific engineering assessment remain the user's responsibility.
