[GRASS-dev] [PROJ] Announcing PROJ 6.0.0

#
PROJ 6 has undergone extensive changes to increase its functional scope from
a
cartographic projection engine with so-called "early-binding" geodetic datum
transformation capabilities to a more complete library supporting coordinate
transformations and coordinate reference systems.

As a foundation for other enhancements, PROJ now includes a C++
implementation
of the modelisation propopsed by the ISO-19111:2019 standard / OGC Abstract
Specification Topic 2: "Referencing By Coordinates", for geodetic reference
frames (datums), coordinate reference systems and coordinate operations.
Construction and query of those geodetic objects is available through a new
C++
API, and also accessible for the most part from bindings in the C API.

Those geodetic objects can be imported and exported from and into the OGC
Well-Known Text format (WKT) in its different variants: ESRI WKT, GDAL WKT
1,
WKT2:2015 (ISO 19162:2015) and WKT2:2018 (ISO 19162:2018). Import and export
of
CRS objects from and into PROJ strings is also supported. This functionality
was previously available in the GDAL software library (except WKT2 support
which is a new feature), and is now an integral part of PROJ.

A unified database of geodetic objects, coordinate reference systems and
their
metadata, and coordinate operations between those CRS is now available in a
SQLite3 database file, proj.db. This includes definitions imported from the
IOGP EPSG dataset (v9.6.0 release), the IGNF (French national mapping
agency)
geodetic registry and the ESRI projection engine database. PROJ is now the
reference software in the "OSGeo C stack" for this CRS and coordinate
operation
database, whereas previously this functionality was spread over PROJ, GDAL
and
libgeotiff, and used CSV or other adhoc text-based formats.

Late-binding coordinate operation capabilities, that takes  metadata such as
area of use and accuracy into account, has been added. This can avoid in a
number of situations the past requirement of using WGS84 as a pivot system,
which could cause unneeded accuracy loss, or was not doable at all sometimes
when transformation to WGS84 was not available. Those late-binding
capabilities
are now used by the proj_create_crs_to_crs() function and the cs2cs utility.

A new command line utility, projinfo, has been added to query information
about
a geodetic object of the database, import and export geodetic objects
from/into
WKT and PROJ strings, and display coordinate operations available between
two
CRSs.

In addition to the new version of PROJ we are also releasing new datum grid
packages:

proj-datumgrid-europe 1.2:

  https://download.osgeo.org/proj/proj-datumgrid-europe-1.2.tar.gz
  https://download.osgeo.org/proj/proj-datumgrid-europe-1.2.zip

  Changes include: Grids covering the UK, France and Sweden.

proj-datumgrid-north-america 1.2:

  https://download.osgeo.org/proj/proj-datumgrid-north-america-1.2.tar.gz
  https://download.osgeo.org/proj/proj-datumgrid-north-america-1.2.zip

  Changes include: NAD83 -> NAD83(HPGN) grids, GEOIDB12 grids and the
  Canadian ntv2_0.gsb grid

proj-datumgrid-world 1.0

  https://download.osgeo.org/proj/proj-datumgrid-world-1.0.tar.gz
  https://download.osgeo.org/proj/proj-datumgrid-world-1.0.zip

  This is the first version of the world wide package. Currently it only
holds
  the EGM2008 geoid grid.

[GRASS-dev] Introduction and Idea ( GSOC 2019 )

[Soumya kanta Das]

Hello,
Myself Soumya Kanta Das, studying Geo-informatics. Currently i work on
automating geospatial workflow and Machine learning applications. I have
previously worked on automated identification of buildings in Satellite
imagery using Deep learning. I have language proficiency in python.

I would like to develop a Deep learning module for grass using tensorflow
library and python 3. Which would be very helpful for end-users.

Thank you.

Comment (by neteler):

 I have updated the grasswiki Mediawiki settings (hopefully right), please
 try again.

something already exists in GRASS GIS addons using tensorflow [0], you
can have look there..
