Proof of Water on Mars

This is official image taken by ISRO Mars orbiter Mission. This is first time any space agency shows water vapor cloud image from mars, officially. Presence of cloud, is proof of water, it may be formed from polar region or from an location where water is very near to surface. So if this water is drinkable then life on mars is possible , we just need to begin it with seeds, plants. This will change whole planet. In near future may be some of our relative living on mars, and we may have tour and travel pack for mars. This is absolutely possible. Even after thousand's years its possible each one has his own small space travel ship like car or bike. From which people go to mars with own convenience. As fuel there should be electrical inject, which may be fireless and it having its own gravity during travel. All this theoretical and logical possible, just need to do it.

3D Printing Benifits for GIS and Other

3D Printing gives us New Era of Visualization and analysis of Real World items. You can Now Print your Digital Elevation Model using this. Its accuracy is much higher then human being. Beside this you can Design and Print anything any component in 3D. Which may be A teeth or A part of Body even of Car almost anything. For making it Use Single Material Like Plastic or two set of plastic of Different color, or Even iron of Gold also.  it takes 4 to 5 hrs to make item depnding on your choice. See of 3D printing.


A Computer that Moves Real Chess Paw and Play Physical Chess With you.

What if Computer do some Extra out form Your LED Screen. it may be amazing. Hers its possible by automatic chess playing Machine. Its moves your chess paw like human. Concept comes from small sensor below each paw and and below chess board, Below chess board there is magnet that using coordinate system and connected to computer to monitor your each chess moves. its nearly about impossible to win from this computer. Have a Look in Below video.

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
