The OS OpenSpace API is a piece of software code you can embed in your web application that provides all the necessary functionality to interact with a map, like panning, zooming in and out, and adding markers and polygons.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
Web-map builder designs your map, as you want it, then prepares and writes the web page for you. When you’ve finished adding markers and routes, just collect the final script and copy it into your web site editor for an instant customised web map.
