ColorBrewer is a web tool for selecting color schemes for thematic maps, most usually for choropleth maps. It includes 35 basic schemes with different numbers of classes for over 250 possible versions. Each scheme has CMYK, RGB, Hex, Lab, and AV3 (HSV) specs for the colors. The software is designed simply to list color specs for a scheme you find useful so you are able to create these colors in the mapping software you are using.


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.
