2020-10-23merc.rst: change "origins from 15th cent" to 16th cent.Charles Karney
2020-10-22merc.rst: revert to ln instead of log.Charles Karney
Also define merc (resp. tmerc) as the conformal projection in which the equator (resp. a chosen meridan} projects to a straight line at constant scale.
2020-10-22Flesh out the documentation for MercatorCharles Karney
This addresses item 1 in issue #2387 Things to note: * I made "editorial" changes to the text. The virtues and vices of Mercator are a hot topic. So check these out. (I judged that the text I replaced to be pretty misleading.) * I include the radius of the sphere/ellipsoid in the formulas (and I did this also for my mods for tmerc documentation). Surely this is better than leaving the reader to figure out how this is introduced. * I include the "old-style" (ca 18th century) formulas and the newer ones in terms of hyperbolic functions. The former may be the familiar ones, but the latter are better for computation (more succinct, more accurate, faster, preserve parity). * For the inverse ellipsoidal transformation, I just say that the formula for psi is inverted iteratively. This is probably sufficient, but it could be expanded later.

2020-10-18Document the default poder_engsager algorithm for tmerc. (#2379)Charles Karney
* Document the default poder_engsager algorithm for tmerc. * Give exact expression for phi' in terms of phi * Aadd another datapoint on range of applicability + explanation for complex numbers. * Update tmerc figure with one reflecting poder/engsager algo.

2020-04-24Doc: fixes for Sphinx 3.0 compat [skip appveyor] (#2191)Even Rouault
Those changes are also compatible with Sphinx 2.x The use of .. cpp:enumerator:: for a C enum is questionable, but .. c:member:: no longer works in Sphinx 3 for the value of a C enum, but .. c:enumerator:: is Sphinx 3 only ( https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#directive-c-enumerator ) Sphinx 3 is also more strict with the use of cross-reference to C types. It rejects cross-references to things like `` :c:type:`int` `` since this isn't a type we actually define.
