The default map type view in the MapBrowser is Vertical view, which lets you see Nearmap vertical aerial photography.
Our vertical imagery has been orthorectified; that is, it has been transformed in such a way that each point on the map looks like it was photographed from directly above it. Orthorectification makes vertical aerial imagery suitable for use as a map and allows georeferencing.
If you have switched to another map type, this is how you can get back to Vertical view:
- New MapBrowser, select Vertical in the Compass list.
- Classic MapBrowser:
- US: in the Toolbar, click View -> Map, and then click PhotoMaps.
- AU: Click Vertical in the view mode located in top right hand corner.
This document includes the following sections:
There are five/six available view modes, depending on the MapBrowser you are using:
Vertical - This is the standard, fully orthorectified overhead aerial map.
Panorama - Panorama imagery offers a 45-degree angle view of a location, when available.
Terrain - This map type lets you view the terrain. It can be very helpful to switch Street Maps or Properties on while viewing the terrain map to make navigating the map easier.
Roads - The Roads shows a view of the street maps only, with no aerial imagery visible.
3D - The 3D shows you the imagery.
The most current survey we have captured will be the default map shown whenever you connect to the MapBrowser, so make sure you revisit the site regularly to view the latest imagery.
First Imagery Dates
We have captured imagery of Perth since November 2007. Sydney, Melbourne, Adelaide, and Brisbane images go back to late 2009. United States image captures began in 2014. No prior imagery is available.
You can scroll back and forth between dates on which we have flown surveys using the timeline.
How Much Area does a Pixel Cover?
It varies. It is affected by how far you are zoomed in, but even at a single zoom level, the area covered by a pixel will vary.
The MapBrowser displays maps in the same projection as most other web maps, EPSG:3857 (basically the same as EPSG:3875 and EPSG:900913). While this allows the world to be projected onto a rectangular map, it means that individual pixels will vary in the amount of actual Earth area they cover, depending heavily on distance from the Equator. The pixels themselves do not each represent a perfect square of the Earth's surface either.
Using the Export and Save Imagery tool, you can request image downloads in projections in datums such as GDA94 and NAD83, which apply only to specific locations and more accurately match the real world. When you select one of these projections using the tool, the pixel size for the saved image will be shown in the Save PhotoMaps panel.
