To enable greater flexibility and a more interactive map experience, a college and I have developed a Dash Leaflet map component. It is a light wrapper around React-Leaflet, with syntax similar to other Dash components and naming conventions following the React-Leaflet API. Not all React-Leaflet com…

Hi everyone, Just thought I would share the project I’ve been working on using the Dash-Leaflet app in Python that plots rocket and drone flight data (GPS, accelerometer, and barometer) from a CSV file. So far I only have the GPS and altitude data plotting nicely there’s a fair bit still to be done…

If you use a Circle, it will stay the same size in meters, i.e. it’s rendered size in pixels will change on zoom (on the other hand, a CircleMarker will stay the same size in pixels, i.e. it’s size remains fixed on zoom) It sounds like you are looking for the maxZoom property of the Map component Y…

Thanks Emil for so many pieces of advice! I will get to work trying them! Really love this Dash-leaflet project! You’re a legend!

First of all, thank you so much Emil for your dedication regarding Dash-Leaflet and your responsiveness here in the Forum! I have two issues that might be related somehow to rendering, though I do not think they are directly linked. One is the exact same one as user inisamuel posted some time ago…

Thank you for the kind words :slight_smile: When you re-render the map, the EditControl state is reset. I haven’t worked persistence myself , but it looks like it might be the proper way to address this issue. However, it would require changes to the dash-leaflet source code. Another solution wou…

Thanks again for your response. Would you want me to write two issues on Github to keep track? Also, do you think it is realistic that the issue with filtering and clustering could be solved sometime in the not too distant future?

Thanks for the prompt response. Excerpt from documentation. Leaflet Zoom Fractional zoom A feature introduced in Leaflet 1.0.0 was the concept of fractional zoom. Before this, the zoom level of the map could be only an integer number (0, 1, 2, and so on); but now you can use fractional numbers lik…

Ah, yes, now I understand. You should be able to pass that property (i.e. zoomSnap) directly to the Map component, thedirtyfew/dash-leaflet/blob/4cd75c7b0304cf34072f44969a35a8c8e2c84023/src/lib/components/Map.react.js#L214-L221 /** * Forces the map's zoom…
