I am going to build a website either in Angular 5-6 or in something similar to Drupal. I have experience building websites, but I am going to need to show massive amounts of data in a globe similar to google earth.

For example, this globe will need to show up to three million points where certain types of rocks have been found. I have all of the data, I'm just not familiar with any newer technologies to visualize this data in a web page.

My requirements are that the technology be something fairly new/cutting edge, and be able to render hundreds of thousands, or possibly a few million data points on a map in a reasonable amount of time (feel free to use your own definition of reasonable).


You could create one or sevaral "heatmap" layers from your processed data. This layer then gets shown when the user has a birds-eye view (focuses on, say, the entire earth), but the "heatmap" eventually gets replaced with specific markers for the point data only when the user zoomed in and has chosen a smaller region of interest.

You could also use "MarkerClusters" for smaller patches of close-by points.

In sum there exist common GIS techniques for visualizing such type of data. So maybe ask this on the gis.stackexchange website (do not cross-post the same question, modify it a bit), maybe try these tags: "webmapping", "simplify", "smoothing", "kriging" ...

    The heatmap when zoomed out, then individual points when zoomed in sounds exactly like what I want. Thanks for the link to the gis stack exchange, I didn't know that existed. – trueCamelType Oct 16 '18 at 13:24

    There are many, many ways to interpolate such a layer from point-data, which best to use depends on user requirements and data characteristics. I don't think there is a single "best way". – knb Oct 16 '18 at 14:05
