There are various features of the Bird.i Portal. Images seen here are aggregated from the world’s leading satellite providers, so that what you see in the image finder is the most recent and highest quality image available for that location. Our Timeline feature (on the left) provides you with historic satellite images of a defined area of interest, taken at specific dates and times.
1. How to login
Once you have created your account you will have full access to Bird.i’s Portal. You can access the portal using the ‘sign in’ button in the top right-hand corner of the homepage (https://www.hibirdi.com) which will take you directly to the Portal login page. You can also access the Portal login directly at https://login.hibirdi.com.
2. Using the portal for the first time
When you first log into the Portal, you will be offered a short virtual tour to show you around each feature. If you wish to take the tour at a later stage, you can access this at any time from the profile menu (top right) under ‘Take the Tour’.
3. Image Service features
3.1 Understanding the basemap
The image you are first presented with in the Portal (before the Bird.i image viewer is activated) is known as a basemap. Bird.i’s basemap is supplied by Google and can be clicked, zoomed and dragged in the usual way to navigate to your area of interest. Browsing around the basemap does not consume any credits – this only occurs when the image viewer (top right circle) is switched on.
Once the image viewer is switched on, you are presented with the latest satellite image. The basemap remains in all areas surrounding the image viewer, to make for easy navigation and comparison to older imagery available online.
3.2 How to search for images
You can easily search for a location on earth using the search bar on the left hand side of the map. You can search for locations in the following formats:
- Type an address: e.g. Hickson Road, Sydney, NSW 2000
- Input latitude and longitude coordinates: e.g. -33.851341, 151.211379 or 33° 51′ 4.8276” S, 151° 12′ 40.9644” E
- Input simple place names: e.g. Sydney, Australia
The image viewer will default to the centre of the location.
3.3 How to use the Image Viewer
To turn the image viewer on or off, click the circle at the top right of the screen. Once this is activated, you will be charged for each new image you view.
To move the image viewer, simply click and drag to the desired location on the map.
To turn off the image viewer, you can also click the ‘X’ icon above the image viewer.
The top of the image viewer illustrates the acquisition date and time for that particular image.
The foot of the image viewer contains coordinate information which you can easily copy and paste into another application.
3.4 How to operate the zoom level
The zoom level of a satellite image determines how much of the map is visible. A zoom level of 0 (zero) means that you would be able to view the whole world. At the other end of the spectrum, a zoom level of 19 would mean that even the smallest of roads would be visible. In the Bird.i Portal, when you zoom in and out on the map, the zoom level will be between 16 and 19. This high zoom level lets you analyse even the smallest details of a satellite image.
To zoom in and out of the map click the plus and minus signs in the bottom right corner of the screen.
3.5 Understanding differences in image resolution
Satellite operators provide images with different resolutions, and because we use a variety of different satellite providers, you may come across imagery with differing resolutions. If you zoom into a satellite image in the Portal and it becomes blurry, this may be due to the number of pixels in the image. For example, if an image has a definition of 5m, this means that each pixel represents 5 meters of ground.
The satellite providers we use take images with resolutions between 30cm and 1.5m, so you may come across images at a resolution anywhere in between these levels.
3.6 How to download an image
To download the current image you see, click the centre download icon directly above the image viewer. The image will be downloaded in a rectangular format, containing what you see in the image viewer. This image will be in a .png format and will be downloaded at the current zoom level.
3.7 How can I view a map of the location in the satellite image?
To view location labels on the satellite basemap, you can use the buttons located in the top left of the Bird.i Portal. You can switch between ‘Google Satellite’ and ‘Google Streets’, which will change the basemap in the background accordingly.
3.8 How do I view historic images of my area of interest?
Our Timeline feature allows you to search and view historic satellite images of earth. You can access all of the satellite images that are available at any location. For a comprehensive view of how a location looked in the past, compare different satellite images of an area to analyse whether there may have been any changes. The timeline, on the left hand side of the map, allows you to scroll back through historic satellite images that have been taken over the location that you are viewing inside the image viewer. There can be up to 100 images available of this location, going back up to 5 years, which provides you with the ability to analyse any changes that may have occurred over this time period.
