Analyzing and Understanding Spatial Algorithms
SQL is a powerful tool not only for data exploration but also visualization and subsequent queries. Once you begin writing SQL, you should notice a pattern to writing successful queries. In this chapter, we will begin refining and expanding how we use SQL, as well as building data questions as we join data tables and learn how to run queries in QGIS as well.
The next steps include interfacing with QGIS and running geospatial queries in a GUI that will allow advanced filtering and layer styling, across databases.
This chapter will cover importing a variety of file types into databases along with connecting to databases and executing SQL queries in both pgAdmin and QGIS. We will also cover Spatial ...
