The ‘Data Source Manager’ window that pops up, browse for the ScrapeHero CSV file as File name. Go to the Layers tab from the main toolbar, select Add layer > Add Delimited Text Layer We will add a new ‘Delimited text layer’ and assign Longitude as the X coordinate and Latitude as the Y coordinate Latitude and Longitude fields are the coordinates, and each record in the table will get added as a point vector. Each record in the table has the fields Latitude and Longitude, based on which we can plot the points on the map. The CSV file from ScrapeHero appears as shown when opened in Excel.

Once we add the base map, we need to import the store location data as a point vector layer. You can see OSM added as a layer in the QGIS layers tab and seen in the map canvas area. Go to the Layers tab from main toolbar, select Add Layer > Add XYZ Layer > Select OpenStreetMap > Add: You can use many other similar base maps like Google Maps, Mapbox, Bing Maps, etc. We will use OpenStreetMaps (OSM) as our base map as it the default in QGIS. The Base map layer provides background details like roads, points of interest (POI), building footprints, rivers, etc.

Export the map from QGIS to an image or a PDF.

Edit the symbology and label appropriately.

Import the CSV file downloaded from the ScrapeHero store as a point vector.

The steps to place the point data over the base map of a region/country are: You can know in which city the stores are located, the nearby towns, roads, lakes or similar geographical features adjacent to the store, and many more. Furthermore, when we plot points above a base map, we can attain more information about the data points by simple visual interpretation. When we plot locations on a 2D surface, the points’ spatial relationships, such as their proximity to each other or aggregation, are easily understood. The easiest way to understand the store location data better is to plot it as a map.

You can download a sample CSV file or buy the full data from the link below. This data contains each store’s latitude and longitude coordinates, which you can plot as points over a map. For this tutorial, we will use the complete list of Subway store locations in the United States. We will use one of the store location datasets from the ScrapeHero Data Store. It also enables a wide range of different spatial data analyses using different tools and plugins available with QGIS (for more QGIS tutorials, click here ). QGIS helps create, edit and visualize geospatial data.
