ZeeMaps

ZeeMaps quickly maps point data on Google base maps in two ways:
1) The user uploads a .csv file of data points and their locations.
2) A group of users all add their own data location points to the map, on their own time from their own devices.
Each point can include text, video, image, or audio annotations.
Basic functionality is free; larger uploads and large numbers of maps require a paid subscription.

Google Maps

Google Maps is a web mapping service application that includes street maps, satellite images, street view perspectives, as well as web functions such as routing and geocoding. The API can be used outside of the normal Google Maps interface for other projects.
