This is a really unfortunate title that seems like it might be interesting to general math-inclined people, but instead is only interesting to a very small group of engineers working in a very specific domain.
- dmahr 6y agoYou’re totally right, I made it for GIS people, not general math people. No idea why it’s on HN tbh
- ecommerceguy 6y agoLots of GIS people on HN it seems. My favorite projects were always raster based model projections for various infrastructure and demographics.
- iudqnolq 6y agoAs someone who isn't a GIS person but is trying to make a map-centric app (hiking/backpacking, with activity tracking and route planning), any suggestions for resources? I just finished implementing enough of the WMTS spec interact with the one provider I'm using so far (UK ordinance survey). The only library I could find to help that works on Android was proj4j, which I'm using to handle converting points to different CRSs. I'm making incredibly rookie mistakes like just realizing I need to project vector data into the same crs as the raster base map. I want to be able to transparently support changing the base map to one with a different crs and lines and points recorded in the previous crs show up in the "right places", but I can't figure out how that's possible. I think I've seen other apps do it.
- ajdlinux 6y agoI don't work anywhere near geospatial stuff, but this would have been helpful to me a few years ago when I did some hackathon projects that involved Google Maps, frantically trying to integrate a number of different data sources that used coordinate systems I'd never heard of. It's worth having at least a vague awareness of this stuff if you might ever touch anything map-related.
