| Abstract | Elevation contours exist for Dakota County and are as current as the date of the aerial photography. Two foot contours exist for the urban areas of Dakota County, as well as for Nininger Township, for Lake Byllesby Regional Park and for Miesville Ravine Park Reserve. Ten foot contours exist for the rural areas of Dakota County except for Nininger Township, Lake Byllesby Regional Park and Miesville Ravine Park Reserve. | |||
| Purpose | Elevation Contours can be used for surface water modeling applications to delineate watersheds as well as determine direction and volume of water runoff. They can also be used to determine areas of the County that are susceptible to erosion. Used by the private sector for preliminary planning of developments. | |||

| Attribute Accuracy | The physical features overall have been collected with a high degree of confidence and are as current as the date of the aerial photography. The physical features collected from the lower level photography (flying height of 3000 & 5000 feet) were more readily identifiable then those of the higher level photography (flying height of 20,000). | |||

| Horizontal Positional Accuracy | The physical features overall have been collected with a high degree of confidence and are as current as the date of the aerial photography. The physical features collected from the lower level photography (flying height of 3000 & 5000 feet) were more readily identifiable then those of the higher level photography (flying height of 20,000). | |||
| Lineage | Contracted vendors used to stereo-digitize elevation 'spot' points and break lines to create an ASCII file. The Department of Survey and Land Information then processed this information to create an elevation coverage called Contour2. Contour2 tiles are merged and converted to a shapefile for network distribution. | |||
