For 3D export to be available, it is required that your organisation have a 3D Export licence and that export credits are still available for your license. You also need to have 3D export permissions, which your account administrator can provide you.
Using MapBrowser you can export (download) all four Nearmap 3D Products, and then use the content in third-party applications.
The following table lists the formats that can be exported from MapBrowser, and the typical download size for each format.
Check the 3D PRODUCTS page for more discussion about these formats:
Note: the typical download size per square km and square mile varies a lot, depending on the complexity of the scene.
|Format||Typical download size per km2 / mi2|
|3D Textured Mesh|
|OBJ||1.4 GB / 3.58 GB|
|SLPK||0.8 GB / 2.05 GB|
|Cesium 3D Tiles||0.6 GB / 0.23 GB|
|3MX||0.5 GB / 1.28 GB|
|FBX||0.375 GB / 1 GB|
|3D Point Cloud|
|LAS||1.1 GB / 2.8 GB|
|TIF (GeoTIFF 32-bit floating point)||150 MB / 358 MB|
900 MB / 2.3 GB

Click the Export tool and select 3D from the drop-down menu:
Note that each 3D capture is made up of multiple surveys, flown at different dates, so the
This means that there may be several capture dates included in the export. These are listed in the ReadMe file that is included in the export.
A range of projections is available relative to the geographical area currently visible in MapBrowser.
A default projection will be pre-chosen that is relevant for the area being viewed and which reflects country standards.
Country defaults are as follows:
If you are not sure which projection to use, stick to the default.
In August 2020 we moved from default exports being based on the WGS84/UTM projection to those above in the list. This aligns with country standards and realises the accuracy of our content when used with existing standard country datasets. You can still set one of these projections by selecting it from Projection dropdown:
There are some projections which are specific and limited to one content type and format. These are:
|ECEF||Textured Mesh||Cesium 3D Tiles|
|WGS84/Geodetic + EGM96||Textured Mesh||SLPK|
Similarly, when you select a projection other than ECEF or WGS84/Geodetic + EGM96, and you select Cesium or SLPK as one of the formats, they will be exported in ECEF and WGS84/Geodetic + EGM96 projections. This is reflected in the Export panel, as shown in the screenshot below:
You can find your UTM zone using this tool:
There are two ways to define your export area:
a. Draw the area you wish to export.
The area can be any shape of polygon, it
If your GeoJSON file is has more than 1000 vertices, you will see a warning dialog like the one shown below. You won't be able to upload that GeoJSON file. Close the dialog and either draw around your area for export, or use a simpler GeoJSON file.
Refer to Valid GeoJSON and Polygon Formats for Content Export for a detailed explanation of other possible GeoJSON errors and what you can do about them.
The Downloads screen will open, showing your downloads list and the status of each download, including the current one.
When the download is ready, you can expand the row to see what files are included in the export. The 3D File Contents guide provides a detailed explanation of each file included in each content type.
Click on the each content block to download the files.
Once downloaded, you can use the files in one of the third-party applications.
NOTE: You can access your downloads at any time by clicking the Downloads button on MapBrowser.
The download status can be any one of the following:
If you want to export a single building, select an area slightly bigger than the building you want to export, to avoid getting an incomplete 3D image.
When you click the EXPORT button the export process is supposed to start, as you will be able to see in the Downloads screen. If you clicked the EXPORT button and nothing happened, your firewall or proxy server may be blocking these addresses:
