### Oblique azimuthal stereographic projection: deriving the point-of-tangency

As a small part of a larger analysis problem, I have a set of Cartesian coordinates (x, y in meters) that define a grid of points on a projected plane. I need to convert these points to (lon, lat). ...

### Polar projection results in loss of data displayed, odd clipping near poles for MODIS (but not DEM) in GEE

I want to create visualizations (static and timelapse) of MODIS etc. with a polar projection (such as WGS 84 / EPSG Alaska Polar Stereographic, as used by ArcticDEM Explorer) in Google Earth Engine. ...

### Lunar Reconnaissance Orbiter (LRO) stereographic projection transformation equations issues

I have been trying to figure out the coordinate frames the Lunar Orbiter Laser Altimeter (LOLA) team uses for data. In their dsmap_polar.cat file they state: where λ is the longitude and X and Y are ...

### Creating Left and Right Image pair to view with 3D goggles in stereo from DEM or Hillshade?

How does one create the stereo pair for viewing in a program such as StereoPhoto Maker? I have processed lidar that I'd like to turn into hillshades and then view in this kind of software, with 3D ...
