If picture is worth a 1000 words, the quality of an image is worth many more when applying remote measurement technology.   There are many factors that should be considered when evaluating remote measurement services.  A small difference in photo compression  and resolution can lead to inaccurate measurements and costly project overages.

 Image resolution and compression are important factors in obtaining the accurate roof measurements.  Many providers of satellite and aerial images offer lower resolution, heavily compressed images to reduce the cost of storing and serving the images to the public.  These compromises degrade the quality of the image, resulting in poor quality measurements.

See examples images below comparing the same house comparing resolution and image compression:

Looking at the images, the low resolution images (bottom) appears blurry and some of the detail visible in the high resolution image (top) has been lost.  The heavily compressed version (lower right) also appears blurry and the artifacts produced by the compression further degrades the detail found in the lightly compressed image (bottom right).  When the effects of low resolution and compression are combined (bottom right), most of the important details of the roof, such as ridge and valley lines, have been lost. The loss of the feature detail reduces the accuracy of measurements made from the degraded photo.

EagleView selects the highest quality, highest resolution images available for each measurement.  These high resolution images provide state of the art pixel resolution (5-6 inches per pixel), compared to the typical (12-18 inches per pixel) resolution images found in most image libraries.  The quality and clarity of our aerial images help EagleView to provide the highest level imagery and high quality aerial measurement reports.
