We just had a new beta release for PlanIt! The main enhancement in this beta release is to bring different modes to the viewfinder. In the previous beta release, we used the elevation service to draw the ground contour. While it works, the display is not very attractive. In this release, we improved it using two approachs – use the phone camera to create an augmented reality, and use an existing picture to replace the ground contour. We called the existing ground contour mode – the ViewFinder (VR) mode, the camera AR – ViewFinder (AR) mode, and the picture one – ViewFinder (Picture) mode. All three modes can be selected by clicking on the map icons on the action bar.

Take a look at the three pictures below. You can see the camera location and the scene location in case you would like to try it yourself. I also attached the jpg file I used in this example as well as the .xmd file which is the metadata file used by PlanIt! along with the picture.

The left one is the ViewFinder (VR) mode. As you can see, it shows a contour of the Half Dome but without any other details. The right one is the ViewFinder (Picture) mode. Because it is a real photo, you can see exactly what it would look like at this particular location. Most importantly, you can adjust the time to see the position of celestial objects in the future or in the past using this real photo as background.

If you are at the location, you can also turn on the phone camera to take a picture or use the augmented reality.

You can download the Half Dome photo I used in this post below. The corresponding data associated with this photo is also included below. I strongly encourage you give your own photo a try. Even with the same scene, you can compose it with Sun, Moon, star-trails, or milky way, and to give it a different feeling.

Picture file used by in this post

You also need a .xmd file. Just copy the text below and save it at the same folder as the picture file using the same file name except with “.xmd” at the end. If you save the picture file above as “pic1.jpg”, then save this xml file as “pic1.jpg.xmd”.
