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. 


See image Quality Demo in this Video

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

Live Earth HD From Space (CAM-1)

International Space Station has Equipped with Earth Viewing HD cameras to See Earth Live. This is in Experimental mode. Sometime Live Stream may not be available due to Signal Problem in space, or Space station at Dark Side of Earth, Sometime Astronauts switching Live camera.. Notification will be displayed for such events. See Live video of Earth below.

List of GIS Topics for M.Tech or Ph.D Project

  1. Land use and Land cover analysis and Change detection. Even future Prediction.
  2. Change analysis of cost line using past data of satellites and find relation between climate change sea level rise.
  3. Impact of Climate change on Groundwater.
  4. Analysis of Groundwater Potential Zones using Remote Sensing and GIS, Using Geology, soil, strata chart, DEM data. Total 22 Layers approx. to run analysis.
  5. Network Mapping, Shortest route, Digital database of route for GPS tracking Device.
  6. Development of GIS Data Hosting Server.
  7. Flood Risk mapping, Identification of Danger zones and damage.
  8. Identification of Hydropower Sites Using DEM and model development for different criteria.
  9. Mapping of Normal and Abnormal route of cyclone and its damage assessment using past data and future prediction.
  10. Soil Erosion and Sediment Modelling using GIS
  11. Identification sites for solar power plant using solar radiation analysis and cloud cover analysis considering earth curvature.
  12. Identification of Minerals using Erdas Material Mapping, e.g. amount of Iron, Zinc in Soil.
  13. Develop a web application using ArcGIS Engine/Server
  14. Requried Software :- ArcGIS , Erdas,ENVI, IDRISI 
  15. Estimate of crop yield of different crops by relating NDVI crop Health Index over a Study area and develop a suitable model. It considers time series data for different crop and different season.
  16. City Heat Centre mapping Using Thermal Data and also thermal mapping for different seasons and mark safe and unsafe zones when Air temperature reaches upper limit.
  17. Natural Forest loss Mapping by relation climate change data
  18. Impact of Thermal Power Plant on Surrounding Environment. It uses Wind Direction, Temperature data, Land use data Before Thermal Plant and after thermal plant and compare surrounding environment temperature NDVI, Land Changes etc.
  19. Perform Watershed analysis of and area, find runoff, Drainage Density, Suitability of area for irrigation project, Risk and safe zone mapping by comparing soil data and rainfall data.
  20. Glacial Melt analysis and its factor, e.g. change of snowline with time, and Prediction when it melts fully with suitable Mathematical model.
  21. Mapping of Humidity by collecting Ground data, for different month and its impact on different crops and vegetation.
  22. Traffic jam analysis using GIS, using traffic data, mark locations on road where possibility of traffic jam is possible if n/Number of vehicle cross per minute, and suggest suitable suggestion or development of new rout and its path for prevent jam.
