See community licencing and commercial licencing below. Also how to buy a licence. Note that some base layers require an account/payment/password (Google) while other base layers are community layers where they are not officially for general use (just testing and lite use only and may go offline).

Overlayer Viewport (User-Hosted)

Overlayer is Javascript code to show a slippy map (like on the home page of this website). A slippy map (where you pan/slip the map with your finger or mouse) is the name for Google Maps, Bing Maps, Castlemap, etc. and almost all maps are controlled with JavaScript code. Another popular JavaScript slippy map is Leaflet (however it doesn't work well with overlayers/filters). Here is a simple map* for builders (using Overlayer JavaScript) promoting floor plans of granny flats they can build. * copy source HTML code from the above page to your web site. Files required; - HTML is the base code ("save page" or right click and "view page source"). - overlayer-user-options.js which is what button/tiles you want displayed (plus default map options). - overlayer-before.js which is placed at the start of your html page (inside <head>). - overlayer-after.js which is placed at the end of your html page (before the closing </body> tag). - overlayer-style.css for some simple CSS styling. - overlayer-log-script.php (optional file) to log partial IP addresses (e.g. 127.10.**.**) for the past 15 minutes. The log will delay community tiles when your server is under heavy load. Save the file with a .php extension. - overlayer-password-tiles.php (optional file) is to get a tile with a API key/password (Google roads and/or satelite imagery). Save the file with a .php extension.
