I'm looking for an online map which can show many adresses in the same time. And with many I mean nearly 1000.
At first I thought of Google Maps, but afaik this has a limit of under 100, so this is no solution. Does anybody know an alternative?
I am not sure if Google limits the number of markers, but I think first your browser will slow down to a crawl if you try this. Also 1000 markers on a map will give a terrible user experience.
A common approach to this problem is Clustering. Basically you display only a part of the markers based on their proximity and the zoom level you are using. An example would be the MarkerManager. However in larger setups with a larger number of markers it is common to query a server-side API via AJAX with the boundaries of your viewport and get the positions of the markers inside the viewport back in return.

I'm making database with movies and I don't know how to save images from Google images and sort them with certain movie.
In database I have 17000 movies and I crawl them from IMDB with import.io but images are too small. Some advice, please?
There is an advanced image search functionality in google images:
You can use that to get the images you want manually, or if you want to automate this with import.io you can append one of the following parameters to a url in a query:
&tbs=isz:l - large images
&tbs=isz:m - medium images
&tbs=isz:lt,islt:xga - images larger than 1024x768
(there are more parameters you can set, this is not a complete list)

We have developed a Droid Tablet GPS App which utilizes Google Maps. One of our users reports that sometimes the maps show partially blurry:
They are using a wireless connection. And this is an application used in a vehicle (i.e. so the maps update and pan as user moves around).
Does this happen because Google first renders low resolution images and then updates them with high res images? And in this case the connection could have been lost before the high resolution images loaded?
Is there any way to prevent this?
NOTE: please before someone tags this as "Not programming related" listen to me. I am posting here because on the relevant Google Groups the moderator is encouraging people to post to StackOver flow using this tag. (Read More).
No, AFAIK there's no way to prevent this on the client side. It's just how Google Maps works.

I want to download ALL of google maps(not satellite images just the map) at street level as lets say JPG images labelled as maybe the starting co-ords. need ideas for how to do this? what would be the best language/platform to implement this in? approximately how much space will I need to store it?
Unless Google provides an API to do this, you are on your own to scrape the page somehow and acquire the image. And i don't think its possible to store all the images unless you have a few tera bytes to spare.
if you wouldlike to do this more easily and legally - take a look at openstreetmap.org

I'm trying to find out which rules govern user-added content in google maps.
I'd like to know if I can store certain placemarks from google maps on my server and on the client(the latter for the sake of caching).
I have been reading through Google maps terms but could not find a direct answer to this question.
Is this what you're looking for?
You must not...
10.3 pre-fetch, cache, or store any Content, except that you may store
limited amounts of Content for the
purpose of improving the performance
of your Maps API Implementation if you
do so temporarily, securely, and in a
manner that does not permit use of the
Content outside of the Service;
Of course, if your own users are adding the content, it should be fine.
