FAQs

• Page:
  What do I do if my 3D or AI export fails? —

  If your export fails in your downloads page you should see a red “Failed” status next to your download.

  As the download has not been processed you have not been charged at this point. Our developers will be automatically notified about the error and will investigate what went wrong.

  Please do not request a new export for the same location until we have had a chance to investigate and resolve the error.

• Page:
  When you do new 3D captures, will I still be able to view the old ones in MapBrowser? —

  Yes, over time we will add to our catalog of 3D content and historical captured will be made via the date menu in the same way that 2D images are viewed.

  What geoid models are used with Nearmap's 3D imagery? —

  AU: AHD (AusGeoid09)
  US: EGM2008 
  Canada: CGVD2013

• Page:
  When should a I use offline 3D as opposed to online export? —

  Offline 3D is preferable in the following cases:

  • For single exports that are bigger than 50 km²
  • For exports of formats that are not currently supported by online MapBrowser Export.
    Refer to 3D PRODUCTS for a list of Nearmap 3D products that are available via MapBrowser and offline.

  Nothing Happens When I Press Export —

  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 corporate firewall or proxy server may be blocking these addresses:

  • All regions - api.nearmap.com
  • Australia - kepler-exports-prod-ap-southeast-2.s3.ap-southeast-2.amazonaws.com
• Page:
  What is the maximum allowed 3D export size?  —

  Any single export is limited to 50km2/20mi2. This could be any where between 25GB and 75GB in size depending on the format you have chosen.

• Page:
  Does your 3D work in all applications? —

  Nearmap's 3D content can be imported into many popular CAD and GIS applications. In general our different export formats should work with an application that supports that format.

  Demo samples are available to validate that a format works as expected in an application. Contact your Account Manager for demo content.

• Page:
  Can I get a small free export so I can test if the 3D export works in my application? —

  This is not possible, but you can get demo samples for testing application support of formats. These are available from your Nearmap account manager.

• Page:
  How can I export all the 3D you have for certain city? —

  Single 3D exports are limited to 50 sq km or 19.3 sq mi.

  If your city area is larger than this, you'll need to obtain your content via an offline 3D export process. Please contact your Nearmap account manager for this.

• Page:
  Will there be other measurement tools for 3D imagery? —

  The 3D tool set will be expanded over time. We would love to hear what tools you would like included in the future. Contact your Customer Service Manager.

• Page:
  What is the capture date for the 3D that I am viewing? —

  Many photos and surveys are required for recreating a 3D region. Multiple surveys must be processed together in order to get a good 3D reconstruction. The date shown for a scene represents the first month of that capture but the entire scene could be made up of photos taken over one to three months.

• Page:
  Can I remove the trees and just display the buildings? —

  No, the 3D mesh displayed is a continuous surface. No classification or feature extraction has been performed on this layer.

• Page:
  Why is the resolution of your 3D lower than the resolution of your 2D imagery? —

  Processing of textures during the construction of the 3D scene may result in some loss of resolution, detail and colour compared to the original textures used as source images.

• Page:
  Why do the dates for 2D and 3D imagery look different? —

  While the 3D content date of capture will correspond with some 2D images, not every 2D capture is processed into 3D, so switching from 2D to 3D may result in viewing a scene older than the current 2D image being viewed. 3D scenes are processed over a large area and may also be made of images taken over one to three months.

• Page:
  Can I use your 3D in MapBrowser to do BIM? —

  Maybe, it depends on what information you would like to obtain. 3D in MapBrowser is largely about visualisation, so if this helps you understand and manage your buildings then it may be helpful, but a lot of building information is managed as assets and for this you would need a third-party application.
