Available Data

A total of 20 reference orthoimages and 120 maps were used in the experiment.

Each image has a resolution of 2600x1500 pixels. Orthoimages and maps use the same cartographic projection (Lambert conformal conic projection) and can be superimposed perfectly.

The entire set (566MB) is available for download as a single ZIP file on demand.


Example differences

The following samples illustrate each of the six types of differences between the reference orthoimagery and the map.

(A) Extra Facility ortho for extra facility sample scan25 for extra facility sample (D) Extra Road ortho for extra road sample scan25 for extra road sample
(B) Missing Facility ortho for missing facility sample scan25 for missing facility sample (E) Missing Road ortho for missing road sample scan25 for missing road sample
(C) Modified Facility ortho for modified facility sample scan25 for modified facility sample (F) Modified Road ortho for modified road sample scan25 for modified road sample

Orthoimagery and Maps (2600x1500)

The coordinates of all differences between orthoimagery and a given map are available as a single CSV file. They are expressed in pixels in a cartesian coordinate system whose origin is at the center of the image. Differences are never located less than 100 pixels from any edge. Coordinates of differences are thus always in the following range: x in [-1200,+1200], y in [-650,+650].
