+ <h1>CassiniSoldner history</h1>
+ <p>
+ This projection did not existed in GeoTools 2, which was the version at the time
the code has been forked.
+ The Cassini-Soldner projection has been added in a later GeoTools version and ported
to Geotk project,
+ but not to Apache SIS. For Apache SIS the projection has been rewritten from scratch
using:
+ </p>
+
+ <blockquote>
+ IOGP Publication 373-7-2. Geomatics Guidance Note number 7, part 2.<br/>
+ <u>Coordinate Conversions and Transformations including Formulas.</u><br/>
+ Revised September 2019.<br/>
+ §3.2.2 <u>Cassini-Soldner</u>
+ </blockquote>
+
+ <p>
+ Initial implementation in Apache SIS is a direct, non-optimized implementation with
almost verbatim
+ copy of above formulas (those formulas are themselves copy of other publications,
the oldest ones
+ taking their origin two centuries ago). This initial implementation can be seen at
commit
+ <a href="https://github.com/apache/sis/commit/b44873a08fd4c02c8092d97c9ab9d8d9964218c4"><code>b44873a08fd4c02c8092d97c9ab9d8d9964218c4</code></a>.
