Subject: [PATCH] Update overview.md

Fixed a broken link to an external PDF.

Perhaps there is a more canonical location.

-The H3 geospatial indexing system is a discrete global grid system (see [Sahr et al., 2003](http://webpages.sou.edu/~sahrk/sqspc/pubs/gdggs03.pdf)) consisting of a multi-precision hexagonal tiling of the sphere with hierarchical indexes.
+The H3 geospatial indexing system is a discrete global grid system (see [Sahr et al., 2003](https://www.discreteglobalgrids.org/wp-content/uploads/2016/01/gdggs03.pdf)) consisting of a multi-precision hexagonal tiling of the sphere with hierarchical indexes.
 
 The hexagonal grid system is created on the planar faces of a sphere-circumscribed icosahedron, and the grid cells are then projected to the surface of the sphere using an inverse face-centered polyhedral gnomonic projection. The coordinate reference system (CRS) is spherical coordinates with the [WGS84](https://en.wikipedia.org/wiki/WGS84)/[EPSG:4326](https://epsg.io/4326) authalic radius. It is common to use WGS84 CRS data with the H3 library.
