Introduction
What is QGIS and what I want to achieve
QGIS is a powerful Free and Open Source GIS software, you can work with everything that has some spatial characteristics. The aim of this project is to add some tool to the existing raster calculator to facilitate some workflows.
Project proposal
The proposal for GSoC 2021 that I submitted can be found here.
Abstract
QGIS already has an integrated raster calculator, where user can enter an expression that will apply raster algebra functions to one or more input rasters and produce a new raster file. This project aim is to develop a new virtual raster data provider that can help to use the raster calculator without creating a lot of files on a disk. It will be possible to perform the computation on the fly when map gets rendered. It will be therefore possible for the users to see the results of raster algebra expression that has been typed without the creation of derived raster files. For example, it should be possible to compute the NDVI index on-the-fly.

Timeline
17th May - 7th June
Community bonding period:
- Achieved tasks:'
- Setting up Development Environment for QGIS;
- Introducing myself over the channel and shared my proposal on the mailing list for suggestions and feedbacks;
- Getting in contact with mentors and start to dive in the source code and look for some small bugfix I can work on;
- Created a wiki page for the project "A new render type On the fly Raster Calculator for QGIS".
- Forking the repository of QGIS. Here: Forked Repository;
- Creating wiki User page and added my personal information. Here the page is available;
- Updating links on the wiki Google Summer of Code 2021 Accepted page
- Joining Slack channel created by mentors;

Student's Biography
I am Francesco Bursi and I’m currently enrolled at Advanced Master on "GIScience and Unmanned System for the integrated management of the territory and the natural resources - with majors" with specialization in GISCIENCE and GEOINFORMATICS (Level 8 EQF) at the University of Padua, in Italy. I took my master’s degree in civil engineering attending the Polytechnic of Turin in 2017. I'm passionate about informatics and GIS, and I really love OS environment.
