Database / ESRI: use EPSG ellipsoid when possible

2019-04-22T13:49:32+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: update ESRI to ArcMap 10.7.0

2019-03-25T16:31:15+00:00

Database: add operation_version column to coordinate operation tables

2019-03-25T16:00:04+00:00

Database: fix import of deprecated ellipsoid and geodetic_datum from ESRI database

2019-03-18T11:16:00+00:00

Take into account supersession information to filter out irrelevant transformations

2018-12-06T12:45:24+00:00

Database: fix ingestion from ESRI of alias names for deprecated objects

2018-12-04T16:05:32+00:00

Redirect epsg:XXXX and IGNF:XXXX CRS expansions to the database, and remove the data/epsg and data/IGNF files

2018-11-28T23:35:25+00:00

Implement RFC 2: Initial integration of "GDAL SRS barn" work

2018-11-14T21:48:29+00:00

This work mostly consists of:
- a C++ implementation of the ISO-19111:2018 / OGC Topic 2
  "Referencing by coordinates" classes to represent Datums,
  Coordinate systems, CRSs (Coordinate Reference Systems) and
  Coordinate Operations.
- methods to convert between this C++ modeling and WKT1, WKT2
  and PROJ string representations of those objects
- management and query of a SQLite3 database of CRS and Coordinate Operation definition
- a C API binding part of those capabilities

This is all-in-one squashed commit of the work of
