You can be an excellent sculptor, but without the right tools, you would find it difficult to work. Similarly, even if you are very good at programming, building GIS application is a completely different ball game! The best tool you can go for while building GIS applications is QGIS. QGIS is a standalone geographical information system. It simplifies the process of building complex geospatial applications. It comprises of the tools that reduce the time and effort you spend on a typical application. If you are looking to create complex geospatial applications within a short span of time, then this Learning Path is the way to go. Packts Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it. The main goal of this Learning Path is to make mold you into an expert GIS application developer. In PyQGIS: Conquer the Geospatial World with QGIS, you will learn how to use the QGIS system with a specific focus on the PyQGIS library. Before we begin learning, lets draw attention towards the roadmap of the course. It begins with understanding the QGIS system, the Python console, and the PyQGIS library. We then move on to learning how to create QGIS plugins and use them in external applications. We then dig deeper into QGIS Python API, concentrating on how this library can be used to display information on a map. We then look at how external applications that use the PyQGIS library can let the user select and edit geospatial features. We go on to use the knowledge we have gained to implement a sophisticated turnkey mapping system. Then, we will look to create, edit, and optimize a vector layer for faster queries, reproject a vector layer, reduce the number of vertices in a vector layer without losing critical data, and convert a raster to a vector. Following this, you will work through recipes that will help you compose static maps, create heavily customized maps, and add specialized labels and annotations. As well as this, we’ll also share a few tips and tricks based on different aspects of QGIS. By the end of this Learning Path, you will have mastery over the QGIS tool and will find yourself capable of building complex applications with ease.
