Code Explained
- We declare the application as HTML5 using the <!DOCTYPE html> declaration.
- We include the Maps API JavaScript using a script tag.
- We create a div element named "map_canvas" to hold the Map.
- We create a JavaScript object literal to hold a number of map properties.
We also set the initial zoom level and mapTypeId to google.maps.MapTypeId.ROADMAP. The following types are supported:
- ROADMAP displays the normal, default 2D tiles of Google Maps.
- SATELLITE displays photographic tiles.
- HYBRID displays a mix of photographic tiles and a tile layer for prominent features (roads, city names).
- TERRAIN displays physical relief tiles for displaying elevation and water features (mountains, rivers, etc.).
- We write a JavaScript function to create a "map" object.
- We initialize the map object from the body tag's onload event.
Note: Zoom = 0 Earth Level
Zoom = higher number More zoomed in
