The datasets provided by geographers are serialized in a convenient format for ESPON HyperAtlas to a binary file named with the .hyp extension (example: Europe_2007.hyp). As a convention, these ESPON HyperAtlas dataset input files will be now called hyp files.

	A complete description of the ESPON HyperAtlas integration tool, named ESPON HyperAdmin, is available from the ESPON HyperAdmin part of this document.

ESPON HyperAtlas is designed so it can load any dataset serialized as an hyp file. From the "HyperAtlas" menu item of the HyperCarte Web Application main menu bar, once the user has accepted the terms and conditions of use (see Figure 2.1), the ESPON HyperAtlas loads a default dataset: Economy and Social Affairs.

The user can also load a dataset hyp file from his disk via the "File-Open" menu item of the application.

Customized datasets for various topics are also available from the "Datasets" page of the Web Application, see Figure 2.2.
