does anyone know the unit of scale used in scale parameter in ViewPointCenter? I've been looking this on the internet but haven't found anything yet. Thank You!!
scale=>The scale at which the maps extent will be centered on. Scale is the ratio or relationship between a distance or area on a map and the corresponding distance or area on the ground, commonly expressed as a fraction or ratio. A map scale of 1/100,000 or 1:100,000 means that one unit of measure on the map equals 100,000 of the same unit on the earth. more info here
Update: For example, on a 1:100000 scale map, 1cm on the map equals 1km on the ground. more examples here
