Panorama-ttnn

Visualize a collection of panoramic photos.

Panorama-ttnn allows you to upload/share/visualize panoramic photos. It has been created for evaluating lines-of-sight for radio networks, like the one of tetaneutral.net.

Features

• Upload panoramas to web server (i.e: made with Hugin);
• visualize, pan and zoom panoramas, as if you were on site;
• georeference panoramas : set GPS coordinates and elevation by hand and set orientation by pointing at known points;
• visualize a point by lat/lon/elevation on your panorama ;
• see other panoramas locations to evaluate the lines-of-sight;
• view on map for a given LOS between two points/panoramas.

Getting started : upload a panorama

1. Go to the index and click "Ajouter un panorama", let upload process
2. Just click on the image in the subsequent list, and wait for it to be processed (split into tiles) ;
3. Choose "accéder directement au panorama" to view it and use the red up-right box to enter coordinates and altitudes from where the photos have beenn taken. bouclage means that left and right borders are matching exactly (360° panorama).
4. Reference some known points by right clicking (see relevant section), the others will get interpolated and presented to you on the view.

Viewing reference points

You'll see big colored bubbles :

• Blue points : reference points you referenced and pointed by hand
• Red points : other panorama (click and fly to it !)
• Green points : reference points automatically placed (estimated according to the blue ones)

Setting up reference points

Reference points are known points you are likely to see from your panoramas, they are a visual reference and a way to orientate your panoramas.

By default, there are no ref_points, you can create your own ref_points list or use one of the provided lists.

To get started, copy one of the files from ref_points folder in the root folder, remane it to ref_points.local.php and customize it.

Hint: prefer to register the altitudes of the topmost point of a building: they are the easire parts to aim from other panoramas.

Panorama view

This is the main view, you can pan and scroll a panorama.

From this view you can use the Reference points menu. The reference points menu allows you to set the orientation of your panorama by pointing at a known location you visualize on the panorama.
