Key Features

  • Learn how you can use PostGIS for spatial data analysis and manipulation
  • Optimize your queries and build custom functionalities for your GIS application
  • A comprehensive guide with hands-on examples to help you master PostGIS with ease

Book Description

PostGIS is open source extension onf PostgreSQL object-relational database system that allows GIS objects to be stored and allows querying for information and location services. The aim of this book is to help you master the functionalities offered by PostGIS- from data creation, analysis and output, to ETL and live edits.

The book begins with an overview of the key concepts related to spatial database systems and how it applies to Spatial RMDS. You will learn to load different formats into your Postgres instance, investigate the spatial nature of your raster data, and finally export it using built-in functionalities or 3th party tools for backup or representational purposes.

Through the course of this book, you will be presented with many examples on how to interact with the database using JavaScript and Node.js. Sample web-based applications interacting with backend PostGIS will also be presented throughout the book, so you can get comfortable with the modern ways of consuming and modifying your spatial data.

What you will learn

  • Refresh your knowledge of the PostGIS concepts and spatial databases
  • Solve spatial problems with the use of SQL in real-world scenarios
  • Practical walkthroughs of application development examples using Postgis, GeoServer and OpenLayers.
  • Extract, transform and load your spatial data
  • Expose data directly or through web services.

  • 優化查詢並為GIS應用程序構建自定義功能

  • 一本全面的指南，通過實例幫助您輕松掌握PostGIS

書籍描述

PostGIS是一個開源擴展，用於PostgreSQL對象關係數據庫系統，它允許存儲GIS對象並允許查詢信息和位置服務。本書的目的是幫助您掌握PostGIS提供的功能-從數據創建、分析和輸出到ETL和實時編輯。

本書首先概述了與空間數據庫系統相關的關鍵概念，以及它如何應用於空間RMDS。您將學習將不同格式加載到Postgres實例中，調查光柵數據的空間性質，最後使用內置功能或第三方工具導出數據以進行備份或表示目的。

在本書的過程中，您將看到許多示例，介紹如何使用JavaScript和Node.js與數據庫進行交互。本書還將展示與後端PostGIS交互的基於Web的應用程序示例，以便您可以熟悉使用現代方式消費和修改空間數據。
