PROJ/data/sql, branch 6.1

Database: update to EPSG v9.6.3

2019-05-25T12:43:17+00:00

Database: update to EPSG 9.6.2

2019-05-08T20:02:00+00:00

Database: add bd72lb72_etrs89lb08.gsb grid in grid_alternatives (added in proj-datumgrid-europe package per https://github.com/OSGeo/proj-datumgrid/pull/50)

2019-05-08T16:04:29+00:00

Database: register URLs for naptrans2008.gtx and rdtrans2008.gsb (non-free) grids

2019-05-07T09:21:55+00:00

createOperations(): for 'Amersfoort / RD New + NAP height' (EPSG:7415) to ETRS89 (EPSG:4937), make sure that the vgridshift is applied first (ie on Amersfoort datum) before the hgridshift

2019-05-06T18:21:27+00:00

Database: add checks to verify consistency of deprecated flag

2019-04-22T13:49:32+00:00

Database / ESRI: use EPSG ellipsoid when possible

2019-04-22T13:49:32+00:00

Database: use non-deprecated code for SWEREF99 for 'RH2000 height to SWEREF99' transformation

2019-04-22T13:49:31+00:00

Database: import common projections from ESRI projected CRS in structured form

2019-04-22T13:49:31+00:00

That is Transverse_Mercator/Gauss_Kruger, Lambert_Conformal_Conic and
Hotine_Oblique_Mercator_Azimuth_Natural_Origin

Decreases proj.db from 5 853 184 bytes to 5 189 632 bytes.

Database: make conversion & helmert_transformation updatable views

2019-04-22T13:49:31+00:00

- Transform conversion as a view, and when inserting into it, actually
  insert into 3 tables: conversion_table, conversion_method and conversion_param,
  so that method and parameter names are not repeated each time.
- Similarly for helmert_tranformation, insert into helmert_transformation_tabl
  and coordinate_operation_method.

This reduces the db size from 6 344 704 bytes to 5 853 184 bytes, without
significant slowdown for queries.
