What is the definition of measured?

Description

​https://trac.osgeo.org/gdal/wiki/rfc61_support_for_measured_geometries does not define measured geometries.

This is weak: ​http://stackoverflow.com/questions/16750968/what-is-a-shapefiles-mesure-value

This has no definition: ​http://www.esri.com/library/whitepapers/pdfs/shapefile.pdf 

PointM
{
  double X; // X coordinate
  double Y; // Y coordinate
  double M; // Measure
}

Can we get a definition added in the RFC and somewhere in the code base? Maybe in ogr_geometry.h, ogrgeometry.h, and/or drv_shapefile.html?

This seems quite good: ​https://www-304.ibm.com/support/docview.wss?uid=swg21054384

Do you think a link would be enough for the RFC?

ajolma, I think that link should be enough.
