#PointCloud on the world map – now live with #MapComponents!

Our new demo shows how a point cloud can be placed on a map and dynamically adjusted. With the GPU-powered https://deck.gl PointCloudLayer and seamless MapComponents integration, analyzing large data sets is effortless.

Dynamic PointCloud customization
Connecting #deckgl with MapLibre
Full compatibility with MapComponents

Try it now: https://catalogue.mapcomponents.org/de/component-detail/PointCloud
Learn more: https://github.com/mapcomponents/react-map-components-apps/tree/main/pointcloud

The point cloud component of MapComponents is now able to adjust the view on the fly.

Do you have some point clouds of a factory console with pipes and valves overlapping each other? Now you can control the size of the points or the colour of the elements to make the 3D visualisation more workable for you.

The following example of our office was achived with a mobile phone recording. easily and quickly done in real position on the map with #MapComponents.

So much has happened in the last 3 months :) We have released many exciting tools for 3D on web maps or multi-screen working - like the "PointCloud on World Map" or the "3D Tiles Layer Demo". And quite impressive (at least technically, if not visually) is the "Multi-Tab Demo".

#30DayMapChallenge Day 4 - Hexagons

#LiDAR #pointcloud data is usually interpolated to raster DEMs. Today, I used hexagons instead! Hexagons are great for representing densities.

I've used #AHN4 point cloud #OpenData from GeoTiles (https://geotiles.citg.tudelft.nl/), created a 0.5 m hexagon layer and calculated mean elevation & point count per hexagon in #QGIS.

Today, I'm giving a workshop on #pointcloud processing with #qgis at #foss4gbenl in Baarle Hertog/Nassau. The event is great cooperation between @osgeonl and @osgeobe!

Follow the workshop for free at @gisocw.
