In the Optical Online Dissemination Service and catalogue the data is collection based and allows data browse and download through the treeview as well as via geographical search using a static map.

PROBA-1 products can also be discovered through ESA's EO Catalogue (EO CAT), which allows users to browse and download products among the available datasets from ESA and Third Party Missions and instruments, using various criteria (spatial, temporal).

A project proposal with the 'PROBA/CHRIS request for acquisitions' table in attachment has to be submitted to ask for the addition of a new site to the acquisition plan: the request outcome shall be provided after project proposal evaluation and feasibility analysis.

All Proba-1 passes are systematically acquired according to the current acquisition plan, CHRIS data are processed every day to Level 1A and made available to ESA users. Valuable indication whether the acquisition was successfully, cloudy, failed or programmed is reported in the Proba-CHRIS Actual Acquisitions.

Observation over a new specific area can be performed by submitting the request to add a new site to the acquisition plan.

ESA internal users can use their ESAAD account.

Description

CHRIS acquired a set of up to five images of each target during each acquisition sequence, these images were acquired when Proba-1 was pointing at distinct angles with respect to the target.

CHRIS Level 1A products (supplied in HDF data files, version 4.1r3) include five formal CHRIS imaging modes, classified as modes 1 to 5:

ModeNameSwathSpectral BandsNadir ground sampling distance
MODE 1 Full swath width62 (773nm / 1036nm)34m @ 556km
MODE 2WATER BANDSFull swath width1817m @ 556km
