Is your feature request related to a problem? Please describe.
I'm always frustrated when I need to manually convert and save position data from our navigation software into different data formats for sharing and visualization. Currently, our application does not support exporting position data in common geographic data formats like GeoJSON, which limits the ease of integration with other geospatial tools and platforms.

Describe the solution you'd like
I would like an export function implemented in our codebase that can automatically convert a list of Pos objects to different formats, starting with GeoJSON. This function should also support saving the output directly to a file. The function should handle multiple position entries and include relevant metadata (like descriptions and unique position IDs) in the output.

Describe alternatives you've considered
An alternative could be to use external tools or libraries to perform the conversion outside our application. However, this requires additional steps for the users and might not seamlessly integrate with our internal data structures.

Additional context
Integrating this function would streamline workflows for users who need to export positional data for use in GIS software, web mapping services, or for data sharing with other platforms that accept GeoJSON or similar formats. This could significantly enhance the usability of our software in geospatial analysis and collaborative environments.

Anonymous position matching. Its easy to implement but I'm not sure if it is useful, so I leave it here for future reference.

Basic idea, two entities submit their encrypted position. The receiver can match entities by proximity but will never know their position.

Describe the solution you'd like

1. Choose matching area/precision, e.g. by rounding coordinates (see table below)
2. Use hash algorithm to encrypt position.
3. Match entities by hash

Some useful discussion on accuracy and precision: https://gis.stackexchange.com/questions/8650/measuring-accuracy-of-latitude-and-longitude

Additional context
Possible use cases:

• Collision avoidance without revealing positions
• Social distancing applications (however GPS is probably not precise enough)

There exists a number of formats for geo coordinates, including:

It would be useful to have a function that recognizes alternative formats and returns the ISO 6709 standard for GPS coordinates, i.e.:

• Latitude: ±DD.D (e.g. +50.12257)
• Longitude: ±DDD.D (e.g. +8.66370)

This function could also include the possibility to convert from ISO 6709 to the desired output string format.
