Maps on Google map can easily be embedded in blogs etc.
Actual usage is as follows.
Google Japan Blog: Paste Google Maps on my site
The following is an actual example. You can move by dragging.
Show enlarged map
First, display the map you want to embed and click "Link of this page" in the upper right
Since there is HTML code, click it and copy it if it is completed. Then paste it on your blog or page OK.
If you click "Customize and preview embedded map", a separate window opens and you can change the size like this.
It is a fairly useful function, is not it. It might be quite good. It is strange that we have not been implemented until now.
