Hi.
Am I understand you:
- you have text address, may be stored in an article title or somewhere
- you want to have ability to get this stored value, geocode it (to get location), and show the map to this place
- you don't want to create 1500 placemarks
The answer
#1
- if you have 1500 addresses, you can easy to create placemarks based on its address
wiki.zhuk.cc/index.php?title=Zh_GoogleMap_LoadPlacemarks
in this example - you can save your address into text address field
- in this case you can easy get this placemarks in database, and change it as you wish
- you don't need to create this count of maps, only one placemark to one place
#2
What you expect to get for this case, what properties of map do you want to control, because it is a lot of. I can create plugin ooptions to get text address as parameter and show simple map, but I think you want more than that
#3
google restrict geocoding in one time, ie you can't get more than 10-12 placemarks (defined by text address in one time). Look at
wiki.zhuk.cc/index.php?title=Zh_GoogleMa..._when_displaying_map
#4 you have different ways to process your street address to show something. But you really will create at least one article for one street
(using my map, or not)
