Create a Drillhole

A drillhole represents a single borehole — a name, collar coordinates, and whatever other metadata you’ve defined in your drillhole template. Once a hole exists, you can log interval data against it; see Enter Interval Data.

This page covers creating one hole at a time through the UI. To create many holes from a CSV or Excel file, see Import Drillholes.

Open the New Drillhole form

From the Dashboard, click + New Drillhole in the header. A form opens. The fields you see come from your project’s drillhole template — every project’s form looks different.

Fill in the fields

The form always includes a name field at the top — this is the drillhole identifier (e.g., DDH-001). Below that, your custom template fields appear in the order you set in Drillhole Template.

Each field uses the input type defined for it in the template:

  • text / textarea — type freely
  • number / decimal — numeric input
  • date — date picker
  • dropdown — select from your predefined options
  • checkbox — true/false toggle
  • formula — auto-calculated, read-only

Required fields are marked. The Save button is disabled until every required field is filled and every validation rule passes.

Validation while typing

Validation runs as you fill the form. Cells that fail a rule are highlighted:

  • Red — error. Save is blocked.
  • Yellow — warning. Save is allowed but a toast surfaces the issue.

For the full rule reference and how to set rules up, see Validation Rules.

Save the drillhole

Click Save. The new drillhole is created locally and queued for sync to the cloud (a green Synced badge replaces the orange Pending badge once the upload succeeds). You’re returned to the Dashboard with the new card visible.

If you’d like to start logging data immediately, click the new card to open the Drillhole Data page.

Edit collar data later

Collar data isn’t locked in. From any drillhole page, click the pencil (✏) Edit button in the header to reopen the same fields and update them. The same template, the same validation rules — just with the existing values pre-filled.

Delete a drillhole

From the drillhole page, click the 🗑 button in the header. A confirmation dialog appears. Deleting a drillhole removes it and all its interval data permanently.

Tips

  • Pick names that sort. DDH-001 sorts before DDH-002 and so on. DDH-1 and DDH-10 will sort lexically and put the latter before DDH-2 — annoying when you have a hundred holes.
  • Use defaults aggressively. Set sensible defaults for fields like geologist, coordinate_system, or drilling_method in your drillhole template so you don’t retype them.
  • For bulk hole creation, use Import. If you’re starting a project with a known hole list, Import Drillholes is faster than the manual form.
