Overview of this book

GeoServer is an opensource server written in Java that allows users to share, process, and edit geospatial data. This book will guide you through the new features and improvements of GeoServer and will help you get started with it. GeoServer Beginner's Guide gives you the impetus to build custom maps using your data without the need for costly commercial software licenses and restrictions. Even if you do not have prior GIS knowledge, you will be able to make interactive maps after reading this book. You will install GeoServer, access your data from a database, and apply style points, lines, polygons, and labels to impress site visitors with real-time maps. Then you follow a step-by-step guide that installs GeoServer in minutes. You will explore the web-based administrative interface to connect to backend data stores such as PostGIS, and Oracle. Going ahead, you can display your data on web-based interactive maps, use style lines, points, polygons, and embed images to visualize this data for your web visitors. You will walk away from this book with a working application ready for production. After reading GeoServer Beginner's Guide, you will be able to build beautiful custom maps on your website using your geospatial data.

Here, ws stands for the workspace to which the data store is linked.

Managing data stores

Did you enjoy using cURL and Python? We hope so, as we are going to use cURL and Python again, since you are now so skilled! So, let's get information about data stores:

  1. The GET operation lets you know which data stores are available in the configuration. Retrieve the information in Python using the following code:
      import requests 
      myUrl = 
       'http://localhost:8080/geoserver/rest/
        workspaces/Packt/datastores' 
      headers = {'Accept': 'text/xml'} 
      resp = requests.get(myUrl,auth=('admin','pwd'),headers=headers) 
      if resp.status_code == 200: 
        file = open...
