Getting to the bottom of web map performance

Offtopic, but while I may have nerdy GISers gathering here I&#x27;ll shoot my shot.<p>Someone knows what is a common&#x2F;standard way of displaying vector information (points in this case) without having that information scrape-able? Is that even possible? I have a project where I want to sell some georeferenced data and be able to show said data (without all attributes, but showing all points) to potential customers in a map, but IIRC I&#x27;ve never failed to scrape vector web map data so I&#x27;m not sure it&#x27;s even possible. I could imprint them in the tile rasters but then they wouldn&#x27;t be interactable. Thanks<p>(if offtopic ain&#x27;t permitted on HN just delete this, sorry)<p>Edit: So many insightful answers, thank you so much for the pointers HN, love y&#x27;all... and sorry OP for piggybacking.

Interesting article. It&#x27;s been a few years since I&#x27;ve had a play with this kind of stuff; what&#x27;s the best option available for someone to host custom styled vector maps and display them in a performant way? preferably on an open source stack. I haven&#x27;t used MapBox before as I was worried about costs and being locked in. I&#x27;m interested in experimenting with map interaction&#x2F;UX.

Rendering 100K-10M lines quickly is interesting!<p>Now that WebGL2 is (almost) universal, any sense of which techniques make more sense now? Still no geometry shaders afaict, but maybe there is something else in there. We currently tessellate ahead of time - even streaming in from GPUs on our server - but that&#x27;s not how we&#x27;d do it with say raw OpenGL. Maybe there&#x27;s something else close enough now?<p>(If you&#x27;re into that kind of thing, plz email build@graphistry :D )
