How or Can I convert POIs from other formats to QMapShack supported type?

I wanted to import English Heritage site list I've downloaded into QMapShack but it requires a specific SQLite format.

These are the downloads available at the EH website and I wondered if there's a way to convert any of these into a format QMapShack can understand:

Link to the map and data site here: https://opendata-historicengland.hub.arcgis.com/datasets/historicengland::national-heritage-list-for-england-nhle/explore

I'm on Arch Linux and comfortable with the terminal but still getting familiar with mapping in general.

So far QMapShack only supports Mapsforge POI format version 2. This is a Sqlite database file. Open and easy to investigate. That said it should be possible to convert any other database format into that. If it's open and kind of documented.

I would recommend to ask AI to do it (if you have a plan/subscription) or use one of the free AI chats to create a python script.

Yes. You can convert POIs to QMapShack-supported formats using tools like:

GPSBabel → convert many formats (CSV, GPX, KML, WPT, etc.) to GPX (recommended).
QGIS → import/export POI layers to GPX.
Garmin BaseCamp → export Garmin POIs as GPX.

QMapShack works best with GPX files (.gpx) for waypoints, tracks, and routes.

QMapShack works best with GPX files (.gpx) for waypoints, tracks, and routes.

This statement does not hold 100% true 😉

For large quantities of waypoints (or any other GIS element) GPX, and the way it is handled in the workspace, is getting pretty inefficient aka slow. This is why there is a POI dock widget that takes a database.

But for a fairly small number of wapoints (a few hundred to thousand) GPX should be well enough.

There is yet another approach to use such type of data relatively easily: MapServer. MapServer as a proxy can handle many input formats like geojson, shapefile, geopackage, ... and transform this data into WMS or other output formats. WMS can be used as input for QMapShack.

I downloaded some data of the above mentioned source from https://opendata-historicengland.hub.arcgis.com/datasets/historicengland::national-heritage-list-for-england-nhle/explore?layer=0&location=53.296899%2C-1.882220%2C14.00 in geojson format and tried MapServer on Windows with QMS. Here is a snapshot (blue circles & red labels) of the QMS map:

Thanks guys, much appreciated! Lots to try here but I've settled for the MapServer option as it seems to handle it best. Never would have expected that tbh!

I started mapping stuff a few weeks ago never expecting it all to be so complicated!
