Accuracy


1st Generation*2nd GenerationNotes

Ground Sampling Distance (GSD)

3" or 7.5 cm

6 cm for New Zealand

2.2" or 5.5 cm 

GSD vary depending on flight altitude and camera type. Given here is the target GSD. 1st Generation imagery captured in New Zealand has a higher resolution than other regions due to lower flight altitude.

Absolute Horizontal Accuracy

1st Generation captures are more accurate when previously captured with HC2 (13.2" or 33.3 cm RMSEr)
Horizontal Measurement Precision

FAQs

  • Page:
    Imagery looks different at different zoom levels

    Sometimes you'll notice that our imagery looks different at different zoom levels. This is because we have a multi-resolution camera system, and the overview (when zoomed out) comes from a different camera to the detail imagery.

  • 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.

    Why is the imagery not aligning well?

    We capture our imagery surveys using light aircraft. Part of the process for building our maps is to stitch one photo’s image to another. It can be extremely difficult to stitch objects that are above ground or objects that are near or crossing water, and for this reason bridges are particularly challenging.

    How accurate is your imagery?

    Our latest camera systems capture Vertical (orthogonal) imagery with a ground sampling distance (GSD) of 5.6cm (2.2”) and an absolute horizontal accuracy of 21.9cm (8.6”) RMSEr.

    In aerial mapping applications, the ground sampling distance (GSD) represents the distance, measured on the ground, between the centres of two adjacent pixels within a digital image. For example, an image with 5cm/pixel GSD means the locations of two consecutive pixels are 5cm apart on the ground.

  • Page:
    Parts of an object appear to be misaligned

    We orthorectify our imagery using a Digital Terrain Model (DTM) that represents the bare earth. This occasionally leads to stitching artifacts on elevated structures such as buildings and bridges, but does not affect the measurement accuracy of visible contiguous detail.

  • Page:
    Why is there a white sheen over an area of water?

    You may see a glint or glare over an area of water. Zooming in on the imagery can remove this, as the camera settings used to capture close detail are different from the settings we use for the other cameras.

  • Page:
    Why is there a light haze covering some map areas?

    If you come across a light grey or white section in our imagery it is safe to say that it is a section of low-lying cloud. We try to fly in only the best weather conditions, but a minute amount of low-lying cloud is occasionally inevitable and we apologize for any hidden imagery detail. These can likewise create shadows on the underlying ground.

  • Page:
    Strips of imagery missing or blurry

    When a strip of imagery is missing or blurry, it is likely that the aircraft experienced turbulence at the time and we don't have redundant imagery to correct the issue.

  • Page:
    Why do some survey areas appear incomplete?

    We aim to fly when the weather is at its best and when we have obtained an Air Traffic Control (ATC) clearance. However, sometimes we might start a flight in the best conditions but be unable to finish the flight because these conditions have changed. For example, we might obtain a clearance from ATC to fly a certain area but then they might change their minds because there is heavy traffic and they can't let us continue. In this case, we will have to abort the flight. Alternatively, unexpected clouds might start to creep in mid-flight. In this case, we will make the decision whether to abort or continue based on how much of the survey is left and how heavy the cloud cover is.

    If we do have to abort a flight, we will make it a high priority to fly the area again at the earliest time possible, when the conditions are in our favour.

  • Page:
    Why is an obvious edge visible in some imagery?

    Sometimes we may show overlapping surveys and at some places, this may affect the edges of the survey. We may fly different surveys at different resolutions and scales. For example, we may fly a very high resolution for a smaller area. If this is the case, you will have surveys of different dates shown overlapping each other. 

  • Page:
    Why can't I see the entire length of a train?

    Long moving objects like trains may be cut off so you don’t see the entire length of the image. This is unusual in our imagery, but can happen.

  • Page:
    Why do certain parts of a survey area appear to have different colours?

    You may notice slight colour changes in different parts of the Nearmap imagery as they are captured on different days of the year and at different times of the day. Other factors such as smog and pollution will also cause such colour differences. Although we use the same camera settings for each flight, you will see from our historical data that we have deliberately tested different colour balances on our cameras to determine the best settings to maximise the imagery quality. Most areas are too large to be surveyed in one day and we have to fly these over numerous days. You might therefore notice slight colour differences within a survey – for example if we fly late in the afternoon and then continue the survey early the next morning.

    Why are there grid lines across the screen?

    If you see a grid pattern across the map, this is almost always the result of the zoom setting on your web browser. Pressing both Ctrl and either the or -key will usually allow you to zoom in or out. If you adjust the zoom level to 100%, the gridlines should go away.
