[GRASS-dev] New GUI startup: Next steps in GSoC and beyond

GRASS GRASS developer

Dear all,

We will meet to discuss ideas for the new startup of GRASS GIS specifically using the GUI. The meeting will be a video call on Wednesday, July 15, starting at 18:00 UTC.

There are two goals for this meeting: 1) Update list of tasks for Linda for the rest of her GSoC project [1, 2] and 2) rethink the Proposal A3: Data tree and big buttons (Prague 2019 roadmap) [3, 4] in the light of what was done so far.

The best place to see what is currently being worked on is the New GUI Startup project on GitHub [5]. Testing the Location Wizard and Data tab in GRASS GIS (from master branch) is also a good way.

I will send a link to the call here right before the meeting. We will use Zoom.

Best,
Vaclav

Hi Vaclav, all,

just tested master with

GRASS Version: 7.9.dev
Code revision: e321f7589
Build date: 2020-07-11
Build platform: x86_64-w64-mingw32
GDAL: 3.0.4
PROJ: 6.3.2
GEOS: 3.8.1
SQLite: 3.29.0
Python: 3.7.0
wxPython: 4.0.7
Platform: Windows-10-10.0.19041-SP0 (OSGeo4W)

nice work!

maybe something for beyond GSoC:

EPSG is reworking their data models [1] and website/web services:

"Following the publication of the revised ISO 19111:2019 data model, IOGP is
in the process of upgrading the EPSG data model. The changes to the data
model being applied to the v10.0 EPSG Dataset and Dataset available via the
Beta Site are:

- Identification of dynamic datums and of CRSs based on these. For datums
and CRSs affected by this change, there will be no changes to existing EPSG
codes.
      
- Addition of a new construct of ‘datum ensemble’. A datum ensemble groups
together successive realizations of a datum as one. Some CRSs will be
associated with a datum ensemble rather than a single datum. These will
include the generic WGS 84 CRSs (EPSG CRS codes 4326 [geographic 2D], 4979
[geographic 3D] and 4978 [geocentric]). Existing EPSG codes will be
unchanged.

- Addition of a new CRS subtype ‘derived projected’. The term is from the
ISO model and is consistent with other terms in the model, but is a
misnomer. It is a CRS which is based upon an existing projected CRS, so
‘derived from projected’ would be a more accurate description. Many seismic
bin grids are defined relative to a projected CRS – others are defined
independently and later referenced to a projected CRS. Examples of both
approaches will be included in the upgraded dataset.

- Some CRS, datum or coordinate operation entities will be associated with
multiple ‘usages’ – scope/extent (area) pairings."

new PROJ library versions (>=7 AFAIK) will be considering partly these
changes.

a GeoRepository API [2] will be available to query the official EPSG
database.

in future it may be worth to link to the offical EPSG web services/database
instead to epsg.io.
