QGIS2WebMap - A Plugin that exports your project into shareable web map

[Abhijay]

G'day all,

I'm one of the people behind this, so treat it as an announcement — happy to take questions or criticism on it either way.

Many GIS project hits the same wall. The analysis is done, the symbology is finally right, and then the council, the client or the community group asks to see it. Your options are a screenshot or talking someone through a 40-minute QGIS install, usually over the phone.

qgis2web has carried this community for years and it's the reason the problem is as solved as it is. We wanted to push in one specific direction: 3D, and a live preview that makes life just that little bit easier.

So we built QGIS2WebMap: a free, open-source QGIS plugin that exports your project to a single self-contained HTML file. No server, no account, no coding. You can email the file, drop it on a shared drive, or put it behind a council login, and it opens in a browser.

Two things we cared about most:

1. Extrusion and terrain survive the export. If your buildings carry a height field, your pit shells carry depth, or your flood layer carries a depth attribute, those come out as true-height geometry over real elevation rather than flattening to a choropleth.
2. The live preview is a real browser window that updates as you work, rather than a still frame you refresh by hand.

QGIS registers 3D renderers lazily, so for a while extrusions exported perfectly flat from any session that hadn't opened a 3D view first. The height was in the project the whole time — the exporter just couldn't see it.

It's on the QGIS plugin repository now (search "QGIS2WebMap by NIKA" in the Plugin Manager). There are three live demo maps you can open, tilt and download the source .qgz for:

Docs: https://nikageospatial.github.io/qgis2webmap/

Fair warning on those demos: they're Himalayan peaks, the Singapore MRT network and a volcano hazard map, nothing Australian in the set yet, which is a bit rich given where I'm posting. If there's an open Australian dataset you'd like to see put through it , do try out the plugin and post it here!

Otherwise: what's the map you'd export first, and what would it need to survive the trip?

Thanks for reading this far :)

Hey Abhijay, 

Thanks for sharing. In fact I was intrigued by the name of your plugin which is very close to mine (Qgis2OnlineMap).

But mine handles the last mile mostly and can support any web map export from QGIS (qgis2web, Qgis2threejs, etc.) and apparently yours too. 

I wanted to give it try, but the "OnlyMap runtime" got me very sceptical to be honest. Why is that necessary and not distributed with the plugin directly?

I think this may be a limit to the tool in the long term compared to the others QGIS options.

The visuals of the renderings on your website look nice though. 

Cheers,
