   How does the projection coordinate relate to the scanning angle?

   • The projection coordinate relate to the scanning angle by the following simple relation: The viewing instrument on-board geostationary satellites described by this projection have a two-axis gimbal viewing geometry. This means that the different scanning positions are obtained by rotating the gimbal along a N/S axis (or y ) and a E/W axis (or x ).

   How do I use a GEOS projection?

   • The geos projection pictures how a geostationary satellite scans the earth at regular scanning angle intervals. proj-string: +proj=geos +h=35785831.0 +lon_0=-60 +sweep=y In order to project using the geos projection you can do the following: The required argument h is the viewing point (satellite position) height above the earth.

   What is the default meridian / longitude of natural origin?

   • Central meridian/longitude of natural origin, longitude of origin or longitude of false origin (naming and meaning depend on the projection method). Defaults to 0.0. The default convention is to interpret this value as decimal degrees. To specify radians instead, follow the value with the "r" character. Example: +lon_0=1.570796r

   5 days ago · To convert coordinates from WGS84 to UTM, you can enter the WGS84 coordinates into a conversion tool or software that supports the transformation. The conversion process will convert the coordinates to the corresponding UTM coordinates based on the specific zone. Is WGS84 geocentric? Yes, WGS84 is considered a geocentric coordinate system.

   3 days ago · Projected coordinates. proj-string: +proj=eqearth. The Equal Earth projection is intended for making world maps. Equal Earth is a projection inspired by the Robinson projection, but unlike the Robinson projection retains the relative size of areas. The projection was designed in 2018 by Bojan Savric, Tom Patterson and Bernhard Jenny [ Savric2018].
