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.
