Extract POIs from Google Earth could be hard to accomplish due to the information which is dynamic. It means that the further you zoom, the more information pops up but it can be achieved manually. Please follow the steps below in order to save POIs as the KML format.
. First select the area of interest (restaurants, cinemas, pubs, etc).
. Then Save it in My Place
. Perform the next search and repeat until you have enough POIs saved in My Place.
. Go to each saved place and save it as KML format.
. Use a tool like GPS Converter and add the contents until you are done (Open > Copy > Paste and repeat)
. Save the big file as KML
. Use a text editor and open the file and remove unnecessary data.
