I was wondering if this used a Gnomonic projection but the AEQD makes way more sense here (especially if defined in polar coordinates, as I imagine it must be? Then you only need to project the points you actually use?).
Any chance of writing a QGIS plugin with the algorithm?
- tombh 9mo agoThe AEQD projection radiates from the anchor right? Is that what you mean by polar coordinates? This was my first foray into optimising projections so if you have any insight I'd love to learn. If you know anything about QGIS plugins please feel free to make a brief write up in our issues https://github.com/AllTheLines/viewview/issues https://github.com/AllTheLines/viewview/issues
- cozzyd 9mo agoI just mean that you only need it evaluated at the points along the azimuths you consider, but maybe that doesn't make sense computationally and it's faster to interpolate from a grid anyway. I might create an issue after I conceptualize what it might look like more!
