Este trabajo se ha traducido utilizando IA. Agradecemos tus opiniones y comentarios: translation-feedback@oreilly.com
En este capítulo, seguiremos centrándonos en QGIS a medida que avances en tus conocimientos de Python y QGIS. Se trata de conceptos fundacionales, y aprenderlos será fundamental para tus futuras habilidades de análisis geoespacial, incluidos los algoritmos espaciales, la ingeniería de datos, el modelado y la predicción, y el aprendizaje automático.
La integración de QGIS en Python se llama PyQGIS, una API de Python que utiliza protocolos definidos y personalización para automatizar los flujos de trabajo. La automatización es importante cuando se ejecutan grandes scripts o se crean aplicaciones. La integración con una API te permite acceder a una gran variedad de conjuntos de datos para su exploración y análisis. Puedes crear, modificar y consultar objetos digitales de interés que representen características del mundo real.
PyQGIS es una envoltura de la biblioteca C++ subyacente. Todos los métodos y variables de clase implementados por la versión C++ de QgisInterface están disponibles a través de la envoltura Python. Las clases PyQGIS apuntan a funcionalidades dentro de QGIS. No necesitas una instalación separada de Python porque se instala con QGIS directamente en tu sistema.
Python es un lenguaje de programación orientado a objetos. Puedes pensar en los objetos como trozos de ...
