Jquery Multiple Range Slider With Floating Points

I was working on a GIS project, which required four range sliders with floating points to set LCLU change threshold. I finally find out a nice jQuery based multiple range slider at http://jsfiddle.net/q5WEe/1/   The compiled fiddle as a web page source is shown in the Part 1.

Then, my goal was to put floating points on the slider bar value display, but the native jQuery slider bar doesn't support the floating point. jQuery always roundup the floating values to the nearest integer. To display the floating point (for example,0.5 break), I multiplied the max  and values with two and divided the display value with two (Part 2) and then I got jQuery slider bar with floating value as below.





New Version of the National Land Cover Database (NLCD 2011) Release :Webinar Announcement

The latest version of the National Land Cover Database (NLCD) for the conterminous United States will be publicly released on April 4, 2014. NLCD 2011 is the most up-to-date and extensive iteration of the National Land Cover Database, the definitive Landsat-based, 30-meter resolution land cover database for the Nation. NLCD 2011 products are completely integrated with those of previous versions (2001, 2006), providing a 10-year record of change for the Nation. Products include 16 classes of land cover, the percent of imperviousness in urban areas, and the percent of tree canopy cover. NLCD is constructed by the 10-member federal interagency Multi-Resolution Land Characteristics (MRLC) Consortium. This seminar will highlight the new features of NLCD 2011 and the related applications.

Convert TRRM Real Time Binary File into ESRI ASCII

Seven simple steps for converting TRMM binary to ASCII grid using MATLAB

Step1:
 %Open TRMM realtime binary file

trmmFile = fopen('E:\TrmmBinary Processing\3B42RT.2012.03.27.09z.bin', 'rb');  

Step2:
%Move file pointer to the begining of  file

frewind(trmmFile);

Step3:
%Read TRMM value from the binary file having 1140 rows and 480 columns

precipitation = fread(trmmFile, [1440,480], 'float32','b');

Step4:
%Shift precipitation by 90 degree to relate data with equator

precipitation = rot90(precipitation);

 Step5:
%Assign ESRI ASCII GRID HEADER
%After rotaion by 90 degree ncols changed into 1440 from 480 and nrows
%changed into 480 from 1440

We will miss the "father of GIS"

Dr. Roger Tomlinson has passed away. Tomlinson is generally recognized as the "father of GIS.” He is the visionary geographer who conceived and developed the first GIS for use by the Canada Land Inventory in the early 1960s.  This and continuing contributions led the Canadian government to give him its highest civilian award, the Order of Canada, in 2001.  Text for that award reads, “he pioneered its uses worldwide to collect, manage, and manipulate geographical data, changing the face of geography as a discipline.”

Tomlinson tells the story of how this came to be.  In the early 1960s he was working as a photo interpreter for Spartan Air Services in Canada.  They had a contract to identify the best location for a tree plantation in Kenya.  They turned to their young geographer Tomlinson and asked him to develop a methodology.  He tried various manual methods for overlaying various environmental, cultural, and economic variables, but all were too costly.  He turned to computers and found the solution.  Subsequently he sold this approach to the Canada Land Inventory that had the responsibility of using data to assist the government in its land use planning activities.  His GIS approach reduced the task from three years and eight million Canadian dollars to several weeks and two million dollars.
 
He went on to serve the community in many ways.  He chaired the International Geographical Union’s GIS Commission for 12 years, where he pioneered the concepts of worldwide geographical data availability. He is a past president of the Canadian Association of Geographers a recipient of its rare Canadian Award for Service to the Profession.
 
Other awards followed including the James R. Anderson Medal of Honor for Applied Geography (1995) and the Robert T. Aangeenbrug Distinguished Career Award (2005) from the American Association of Geographers.  He was the first recipient of the Aangeenbrug award and also the first recipient of ESRI’s Lifetime Achievement Award (1997). National Geographic gave him its rare Alexander Graham Bell Award for exceptional contributions to geographic research (2010). He is an Honorary Fellow of the Royal Geographical Society and the recipient of multiple honorary doctorates – in addition to his own PhD from University College London.

Impact of Google Maps API v2 shutdown on Openlayers base layers and a easy solution

Finally on Nov 19 2013, Google shut down Google Maps v2 API, which was depreciated in May 19 2010 but was working continuously Nov 19. I was aware of version depreciation, but I procrastinate to upgrade till last minute because of working on too many other things. While checking my Web map (built on Openlayers, Geoserver and Google Maps as base layers (Google Maps API v2) on Nov 20, I saw two map controls one from Openlayers and other from Google Maps API also noticed that map application was unresponsive.


Looking around I found easy steps to fix it without major change in the code-
