Subject [jira] [Commented] (SIS-351) Create metadata, CRS and tabular data editors in JavaFX
Date Sun, 12 Mar 2017 00:38:04 GMT


Martin Desruisseaux commented on SIS-351:

Hello Siddhesh, and welcome!

No JavaFX work started as far as I know, so we are starting from scratch. SIS-43 did not provided
much details about its scope; for a GSoC I think we need to be more specific. This SIS-351
task suggests to focus on metadata and referencing by coordinates because they are the most
mature functionalities currently available in Apache SIS, but the student is of course free
to make his/her own proposal.

> Creates the foundation of a GUI application for Apache SIS based on JavaFX. This application
should leverage the functionalities available in Apache SIS 0.8. In particular:
> * Read metadata from files in various formats (currently ISO 19139, GeoTIFF, NetCDF,
LANDSAT, GPX, Moving Features)
> * Get Coordinate Reference System from a registry or from GML or WKT definitions and
apply coordinate transformations.
> * Show vector data in a tabular format.
> Since SIS does not yet have a renderer engine, we can not yet show maps in the application.
However the application should be designed with this goal in mind.
> This project should create a metadata editor showing the ISO 19115 metadata. We should
provide a simplified view with only the essential information, and an advanced view showing
all information. The information to shown should be customizable. The user should be able
to edit the metadata and save them in ISO 19139 format.
> The project should also create the necessary widgets for showing a Coordinate Reference
System (CRS) definition and allow the user to edit it. Another widget should use the CRS definitions
for applying coordinate operations (map projections) using the existing Apache SIS referencing
engine, and show the result in a table with information about accuracy and domain of validity.
