QGIS Python Project

How to use Python scripting in QGIS to extract data from a shapefile and save it to a text file, as well as how to create a shapefile from a text file.

How to Use (Extracting Data from Shapefile to Text File)

1. Download the airports shapefile: Download the airports shapefile from Natural Earth.

2. Load the shapefile in QGIS: Open QGIS and load the airports shapefile.

3. Execute the Python script: Open the Python console (Plugins -> Python Console) and execute the provided Python script readData.py.

4. Check the output file: Check the root directory for the generated airports.txt file containing airport data.

How to Use (Creating Shapefile from Text File)

1. Prepare the input text file: Create a text file named airports.txt with each line containing airport data in the format name,iata_code,latitude,longitude. For example:

2. Execute the Python script: Open new python file in the console and run writeData.py. This script will read data from the airports.txt file and create a new shapefile containing airport points.

3. Check the output shapefile: Check the root directory for the generated shapefile named airports.shp.
