# Validation

> Run quality checks across your project data and work through the issues.

Manage checks your project data against a library of **validation rules** -
catching depth, spatial, date, completeness and other problems before they reach a
client. Validation is a **Pro** feature.

<Callout type="note" title="A Pro feature">
  The validation indicator and results are available on the **Pro** plan; on **Go**
  they are not shown.
</Callout>

## Run validation

The **validation indicator** sits at the foot of the table panel in the
[table editor](/manage/table-editor). Click **Validate** to run the checks against
the project. The indicator shows the last run - **All clear**, or counts of issues
to look at - and marks results as **stale** when the data changes after a run.

## The results

Open the results to see issues grouped and filtered by **category**:

| Category | Checks |
| --- | --- |
| **Depth** | Depth values and ranges. |
| **Spatial** | Coordinates and positions. |
| **Date** | Dates and date ranges. |
| **Completeness** | Required or expected values that are missing. |
| **Relationship** | Links between records that do not line up. |
| **Quality** | General data-quality checks. |
| **Soil** | BS 5930 soil description checks. |
| **Made ground** | Anthropogenic material description checks, based on AGS 2018 guidance. |

Each issue carries a **severity** - **error**, **warning** or **info** - and a
count of the records it affects. Expand a rule to see each affected record, with
its location, depth and table, so you can jump straight to the fix.

<Callout type="tip" title="Which rules run">
  The rules that run, and whether each is active, come from your **configuration**,
  managed in [Product OS](https://os.gimlabs.io). Validation is also surfaced on
  the [map](/manage/map) as **map advisors**.
</Callout>

<Callout type="note" title="Made ground checks">
  The **Made ground** checks can be turned on or off per configuration in
  [Product OS](https://os.gimlabs.io). Most apply only where the stratum is made
  ground - by legend code or description - though the two terminology checks
  (vague odours, and the term "cinders") apply to any description, since neither
  issue is confined to made ground. Like all validation, they are advisory -
  engineering judgment takes priority.
