The data for the **site plan (sketch)** is derived from the **coordinates of the individual boreholes** within a drilling site.

This information is entered in the master data for the respective borehole under **Location / Coordinates**.

The information is maintained as follows:

- **Borehole coordinates**: Geographical coordinates are stored for each borehole. These form the basis for the display on the site plan.
- **Supported coordinate systems**: Data can be entered in various formats, e.g. GPS or UTM. The data is standardised internally and displayed correctly on the map.
- **Multiple boreholes**: All boreholes at a drilling site are displayed together on the site plan, so that their relative spatial positions are visible.
- **Automatic zoom**: The map section is automatically selected to ensure that all boreholes are displayed optimally.
- **Overview and detailed view**: If boreholes are very close together – for example, in the case of multiple geothermal boreholes – an overview map with an enlarged detailed view can also be generated.

The site plan is based on map data and shows the positions of the boreholes schematically.
