ESRI Launched ArcGIS Earth vs Google Earth

ESRI is new to ArcGIS Earth. It has better resolution images than google earth, but it has much less option compare to Google Earth. Most of images in ArcGIS Earth are better then Google Earth, but short of Photosphere and street view. its GUI is much interactive. Thus they are new here and its version 1.0 just beginning. Download below and have a try.

Calculation of Slope Length Factor LS Factor in ArcGIS

where A[r] is upslope contributing area per unit contour width, b [deg] is the slope, m and n are parameters, and a0 = 22.1m = 72.6ft is the length and b0 = 0.09 = 9% = 5.16deg is the slope of the standard USLE plot. The values of m (=0.6) and n (=1.3) were empirically derived.

The LS factor was then computed using Raster Calculator in ArcGIS to build an expression for estimating LS, based on flow accumulation and slope steepness.

The expression is:

In older Veriosn of ArcGIS as Follow: upto 9.3

(([flowacc] * resolution/22.1).Pow(0.6))*(((([slope]*0.01745).Sin)/0.09).Pow(1.3))*1.6

New Version of ArcGIS from 10.1 to Present as Follow

Power(("%flowacc%") * 30 / 22.1,0.6)*Power(Sin("%slope_deg%") * 0.01745 / 0.09,1.3)*1.6

where Pow (which then means power) is a function in the ArcGIS spatial Analyst
