3D developmental atlases are used in research for capture, collation and analysis of spatio‐ temporal data such as in situ gene‐expression. The most advanced systems are based on a temporal series of 3D models. Examples are the EADHB human embryo atlas in Newcastle and the e‐MouseAtlas in Edinburgh. In this project, we use the 3D spatio‐temporal frameworks in conjunction with a repository to deliver research and educational materials directly in the context of the developing embryo. The interface of the prototype NG‐Embryo portal is similar to that of Google Maps, while the functionality it provides is similar to that of Wikimapia. In this talk, I will be giving a brief demonstration of the portal.
