Overview of <a href="http://sis.apache.org">Apache SIS™ (Spatial Information System)</a>.
<h1>Requirements</h1>
<p>SIS requires Java 11 Standard Edition.</p>
<h1>Classes naming</h1>
<p>Implementations of <a href="http://www.geoapi.org/">GeoAPI interfaces</a> usually (but not always)
begin with {@code Abstract}, {@code Default}, {@code Simple} or {@code General} prefix.
The {@code Abstract} prefix is used when a class is abstract according ISO specifications -
it may or may not be be abstract in the Java sense.
The {@code General} prefix is used when an implementation is designed for use in the general case,
as opposed to other implementations specialized for a fixed number of dimensions or other conditions.
Implementations specialized for a fixed number of dimensions are suffixed with {@code 1D}, {@code 2D},
{@code 3D} or {@code 4D} rather than being prefixed.</p>
<p>Classes that are not GeoAPI implementation are usually not prefixed by any of the above.</p>
