Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The httpd file includes some conditional directives for loading modules."

A block of code is set as follows:

<wps:Data>
  <wps:LiteralData>Min</wps:LiteralData>
</wps:Data>

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

projection: new ol.proj.Projection({
  code: 'EPSG:4326',
  units: 'degrees',
  axisOrientation: 'neu',
  global: true
})

Any command-line input or output is written as follows:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout C:\Apache24\conf\ssl\geoserver-demo.key -out C:\Apache24\conf\ssl\geoserver-demo.crt

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select the Execute process button, and you can see a successful output."
