Coast View

We have initiated a project (Summer 2012-2013) to photograph parts of the coast of Tauranga Harbour as a baseline of "before" pictures?. This is intended to create a permanent record of the Tauranga Harbour coastline. The permanent record approach requires that nothing be missed. The view that we have chosen varies from area to area, depending on the level of development and the contour of the terrain. In some areas, we will cover them more than once at different altitudes and distances.

This imagery will be incorporated into a web based tool as well as be integrated into the 3DPM table for Tauranga Harbour. We would like to capture the rivers of the Tauranga catchment. We also hope to re-photograph portions of the coastline every few years, so that historical data is available for research purposes.

Privacy

Your privacy and security are important to us. The CoastView team takes a number of steps to help protect the privacy and anonymity of individuals when images are collected for Coastview, including blurring faces and license plates. You can easily contact the Coastview team if you see an image that should be protected or if you see a concerning image.

Coast view Images are not real time

Our images show only what we were able to see on the day. Afterward, it takes at least a few months to process the collected images before they appear online. This means that images you look at on Coast view could be anywhere from a few months to a few years old.

Individuals and license plates are blurred

This means that if one of our images contains an identifiable face (for example that of a passer-by on the sidewalk) or an identifiable license plate, we intend to blur it out, meaning that the individual or the vehicle cannot be identified. If our detectors missed something, you can easily let us know.

You can request further blurring of a specific image

We provide easily accessible tools allowing users to request further blurring of any image that features the user, their family, their car or their home. In addition to the automatic blurring of faces and license plates, we will blur the entire car, house, or person when a user makes this request for additional blurring. Users can also request the removal of images that feature inappropriate content (for example: nudity or violence).

How to report a concern

If you've found an image that you would like further blurred, or an image that you believe contains objectionable content, just follow these steps:

  1. 1.Locate the image in Coast view.
  2. 2.Click "Report a problem" in the bottom-left of the image window.
  3. 3.Complete the form and click "Submit."

Turning Photos into Coastview

Collecting imagery

First off we need to actually go around and photograph the locations to show in Coastview. We pay close attention to the sun when planning our driving, and need the sun to be high enough that shadows don't obscure structures.

Aligning imagery with Maps

We need to figure out exactly where each image was taken so you can see an image of the right place when you’re looking in Coastview. To do this, we use a (GPS) device to ground truth the photo and geotag it.The GPS device shows us the car’s exact location most of the time, Since we know exactly when along the line and in which direction each picture was taken, we can then match each image to a specific location, and even tilt and align the images.

Turning photos into a 360-degree panorama

When we photograph for Coastview, to create a continuous 360-degree image, we “stitch” the images together. We know the geometry of all of the different cameras in the system, and from that we determine where in the images we should “stitch” to create a unified panorama. We then apply special image processing algorithms to lessen “seams” where the images meet and create a smooth transition.
