AI Layers are available to view in the MapBrowser.
To view AI Layers you need a subscription to Nearmap AI, and the relevant AI Packs. Contact your Nearmap Account manager to enable AI Layers.
If you have a Nearmap AI subscription, you can view AI Layers in the New MapBrowser from the Workspace. From here you can visualise the attributes covered by your subscription, and optionally overlay the AI Layers and imagery with property or cadastre boundaries.
Viewing parcel boundaries overlaid on AI Layers gives you an indication of what will be present in the export. What you see won't be exactly the same as what is exported, because we use post-processing algorithms to assign objects to parcels, filter out objects (that are too small or too low in confidence), and in some instances work with multiple AI Layers to produce a compound result (such as dominant roof material).
Note that the relative transparency of the AI Layer reflects the confidence level of the particular attribute. The more transparent it is, the less confident we are that it actually is that particular attribute. Refer to the discussion about Confidence on the AI Packs page. The example below shows swimming pools with the more confidently identified swimming pool on the left and the less confidently identified swimming pool on the right.
To view AI Layers:
In MapBrowser navigate to your area of interest.
In the Project Workspace, under the Data Layers panel, check the box against the AI Layer you want to visualise.
Note that the three available roof material types sit beneath both the Roof Material and the Roof Shape dropdowns. Ensure this is expanded and check only those you want to display.
The AI layers are available for particular dates on Nearmap's vertical imagery for Australia and the United States. If you navigate beyond either of these areas, a dialog appears letting you know that you are out of coverage area.
By default in MapBrowser you always see imagery from the most recent survey. If you see a yellow warning icon against an attribute you've selected, it means AI Parcel data for this attribute is not available in this survey.
In the Information Panel on the right-hand, click the CHANGE SURVEY DATE link and the map will automatically load the most recent imagery that has the attribute data.
Alternatively, browse through dates in the date picker until the warning icon disappears.
Use the colour controls in the right-hand panel to adjust the display.
|Background – adjusts all selected AI Layers at once, fading the background imagery between normal visibility and completely black. This can help to minimise distractions so you can more easily identify areas such as construction sites while zoomed out, then zooming in and fading imagery back in to see what is present.|
Colour, Brightness and Opacity – These settings operate independently on each layer. This is a powerful tool to help you choose a relevant AOI, or gain an intuitive understanding of what is going on in a large area such as a suburb or a city.
You can use them to visualise multiple AI Layers at once, by selecting a different colour, for example to distinguish metal versus tile roofs.
You can always use our Snapshot feature to take a picture of what you see in MapBrowser. Just press the Snapshot button at the top menu bar. Your image downloads as a .png file.
