The CADC website is undergoing major changes to improve appearance, web content accessibility and functionality in both official languages. The goal is to provide simpler and more effective ways to access CADC services. Many older CADC web pages will no longer be accessible after April 2014. If you require assistance with this transition please email us here .

Le site du CCDA subit une transformation majeure pour améliorer l'apparence, l'accessibilité aux contenus Web et la fonctionnalité dans les deux langues officielles. L'objectif est de fournir des moyens simples et plus efficaces pour accéder aux services du CCDA. De nombreuses pages Web anciennes du CCDA ne seront plus accessibles après avril 2014. Si vous avez besoin d'aide avec cette transition, s'il vous plaît, communiquez avec nous ici

The image above is the CFHTLS D4 field. You can zoom in and out and scroll around the image the using your mouse and the controls much like Google Maps. Click on the buttons on the right hand side to view the field at different wavelengths.

You can also get a science image in FITS format (for the CFHTLS images only). Pan and zoom to the position and resolution you want, pick the filter, then click on the "Get FITS image" button.

The non-CFHTLS images were produced by taking publicly available images (the list of data sources is here) and resampling them to the scale of the CFHTLS images. In some cases, this causes the images to be drastically over-sampled (the Spitzer MIPS data, for example) or under-sampled (the HST images). The colour images for the CFHTLS data are produced from the gri images.
