Re: My first and foremost wish!

Hello Tobias. Apple’s ARM announcement makes me tired. Yes, of course, Geocart will be released for ARM. That said, there’s very little chance it will be “easy” and no chance it will be soon. Given that they will start with low-powered Macs least likely to be used for Geocart, hopefully that’s not a...

Re: Exported geocart projections

Hello Joe.

Sorry to hear you’re having trouble.

Questions:
1. What version of Geocart, and platform? (3.3.5, Mac?)
2. What projection is in use in the raster reprojection database?
3. What projection are you reprojecting to?

Regards,

Re: GEOCART software itself closed

Hello Daniel. The document you kindly provided separately has no trouble exporting to PDF in our experiments on Geocart 3.3.5. However, we do see problems when exporting via Geocart 3.3.3. You indicate that you are using Geocart 3.3.5, so we are not sure why. With apologies for the inconvenience, we...

Re: Gilbert two-world perspective doesn't make sense

And Delucia and Snyder’s bounding circle is simply wrong. It’s slightly too large, even given the one-to-many mapping near the north pole. I got a chance to look more deeply into this. I had misunderstood something in their paper: They give a value of 2.502° for a constant they call φ ₁′. I thought...

Re: Experimental projections

And the tristandard experimental projection makes this false: I don’t object to a definition of pseudocylindric that permits higher latitudes not to be strictly shorter than lower latitudes, but that’s not the definition in play in the context. The more common notion of pseudocylindric is described...

Re: Experimental projections

The ever-flexible Hufnagel gives an equal-area solution for the pseudocylindric case. A = -0.664 B = 0.376 Aspect ratio = 0.363636 φ ₀ = 52° I didn’t spend the effort to converge perfectly on to three standard parallels, but it’s very close, and it’s obvious that it’s possible. — daan Hufnagel3.jpg ...

Re: Experimental projections

Miljenko Lapaine has a presentation about an azimuthal projection with three standard parallels. It illustrates the fallacy in using projective geometry as a way to think about map projections. Of course, he does not suggest that the projection is otherwise useful.

Why do you keep saying "you know very well"
Why do you keep stating things that you know very well to be true or false already?

Re: What is Add test page items?

Which you know very well is false. Hopefully you’re finished trolling now. If not, well…
