Description of the projects

Example: software XYZ - title of my GSoC project

Student1

• Mentors: Mentor1; Mentor2; OtherMentors?
• Brief description of the idea. e.g. "My project focused on xxx".
• The state of the project as it was BEFORE your GSoC. For example, if you made a GUI, you can say: "In the software XYZ, when I wanted to use the tool xxx, I had to manually edit the file yyy. "
• The addition that your project brought to the software. In the same example: "With the GUI that I created, now it is possible to use the tool xxx via graphical user interface".
• Add all the links (hopefully permanent) to access the relevant code and documentation for the user to get started with testing your application. "Please test my code following instructions here".
• Slide The slide / image should serve to show the main elements of your project. It could be a flow chart, a screenshot, both, or whatever you think could serve for the scope. Remember: the aim is to showcase your project to people that are not necessarily familiar with the software.

Improved Metadata for GRASS GIS

Matej Krejci (picture: http://tinyurl.com/pp69bwd)

• Mentors: ​Martin Landa, Angelos Tzotsos, Luca Delucchi
• Description: The first aim was to improve current package by adding a new functionality for extend metadata handling. The second goal was to implement module for interaction with metadata catalogue services (CSW).
• State of the project before GSoC: In 2014 during GSoC I have developed new GRASS GIS metadata management support based on ISO-INSPIRE. This package needed extension to meet the users requirements. In addition package for CSW searching was missing.
• Addition to the project: New module g.gui.cswbrowser based on graphical interface allows managing csw connections, setting filter and searching, browsing results and adding services to GRASS GIS have been implemented. For g.gui.metadata have been added support: exporting metadata reports to pdf, storing themes of metadata in SQL backend, publishing metadata to CSW and metadata support for Temporal datasets.

ScribeUI - Add productivity tools to MapServer's ScribeUI

Samuel Lapointe (picture: https://goo.gl/photos/LbSwPeMrCG5V2K9t8)

• Mentors: Daniel Morissette; Jessica Lapointe
• Description: The goal of the project was to improve the error detection system, add the ability to export and import maps and add a way to generate a set of classes from data.
• State of the project before GSoC: When I wanted to debug a map that didn’t work, I had to check the generated Mapserver file to find the error. To create classes from a set of data, I had to analyse the data and create the classes using bounds I had manually calculated, and the only way to export a map was to use Git.
• Addition to the project: Now, I can see most syntax errors directly in the editor’s interface, I can use a menu to generate classes for a layer and I can export or import maps to share them with other users.

QGIS - Multithread Support on Processing Toolboxt

Marcus Santos (https://media.licdn.com/media/AAEAAQAAAAAAAATOAAAAJDA1Y2M0MWQ0LTMyYjMtNDlhMi05OWM3LWIxMDQ5YWM1ZTk2MA.jpg)

• Mentors: Victor Olaya, Alexander Bruy
• Description: This project consisted on making the QGIS Processing toolbox multi-threaded, allowing to have non blocking analysis/geoprocessing jobs, prevent crashes (when a QGIS module crashes for some reason) and also improve the user experience.
• The state of the project GSoC: Before the multithreading support, the user was only able to run one analysis at a time and there was no option to cancel the algorithm execution.
• The addition to the project: With multithreading support the user is allowed to cancel long geoprocessing jobs and also run several algorithms at the same time.
