This perspective view of Venus, generated by computer from Magellan data and color-coded with emissivity, shows the boundary between the lowland plains and characteristic Venusian highland terrain in Ovda Regio, the western part of the great equatorial highland called Aphrodite Terra. For a view of the highlands just to the east, see PIA00310. The view is parallel to the northern boundary of Ovda. The black stripe in the foreground is not a data gap; the front part of the terrain has been "dropped down" to show a topographic cross-section through the region. The conical "hill" in the extreme upper right of the image is not a real feature, but an artifact resulting from a single erroneous altimeter measurement. Its size gives an idea of the horizontal resolution of the altimeter. Whereas the lowlands at left are made up of overlapping, relatively dark and unfractured lava flows, the highlands consist mainly of "tessera terrain". The tesserae in the center of the image consist mainly of ridges running nearly parallel to the highland boundary, whereas further south (to the right) the pattern is complicated by north-south trending fractures. Local depressions in the highlands, which have been partially filled in by smooth material, are visible in several places. Magellan MIDR quadrangle* containing this image: C1- 00N077. Image resolution (m): 225. Size of region shown (E-W x N-S, in km): 824 x 520. Range of emissivities from violet to red: 0.67 -- 0.87. Vertical exaggeration: 40. Azimuth of viewpoint (deg clockwise from East): 165. Elevation of viewpoint (km): 520. *Quadrangle name indicates approximate center latitude (N=north, S=south) and center longitude (East).
