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. If this issue…
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.
Import Nearmap Images into 12d
This article provides the instructions for importing an image from Nearmap into 12d Model. MapBrowser Log into MapBrowser using your account username and password. In MapBrowser, locate the Area of Interest (AOI) you wish to capture. Export the AOI as a georeferenced image in the required projection as shown below. NOTE:…
Dark Markings Around Image Perimeter
Description Dark markings may appear on the perimeter of imagery after geoprocessing tools are run on the Nearmap-delivered files. For example, when you perform one of the following tasks: Mosaic to New Raster, Resample, Copy Raster, Extract by Mask. Cause This occurs when the mask file is missing. For example, if no mask…
WMS 2.0 - Images Not Loading
If your application is not able to load images correctly, remove the part of the URL starting from the question mark and try configuring your application with https://api.nearmap.com/wms/v1/latest/apikey/<APIKEY>
Imagery from different UTM Zones in ArcGIS Pro not visible
When in ArcGIS Pro, it may happen that Nearmap imagery on different UTM zones will not be visible. For example using NZGD 2000 UTM Zone 60S (EPSG:2135) you will not see South Island imagery. As New Zealand's North and South Islands are on different UTM zones, both simple and Custom WMS will filter out imagery that is…
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.
Missing imagery and survey boundaries
Imagery capture is a very complex operation. What Nearmap refers to as a “survey capture” is essentially a reasonably stable flightmap, flown on one day. The boundary may change occasionally, but in most cases they are stable. In some cases, due to weather conditions or air traffic control (and a host of other…
Why are some images partly blurry/pixelated?
There are a couple of reasons that you may encounter Nearmap imagery that is blurry or pixelated. Unfocused imagery Holes in our imagery caused by turbulence Imagery Boundary Unfocused imagery When capturing our imagery sometimes our camera system has trouble focusing on the landscape below. This occurs in areas where…
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.
