Vitality of elevation information in the field of Geospatial technologies is a well known factor. This may be in the form of Spot Heights, Contours or DEM. Unfortunately the open source DEM we get is generally of spatial resolution of 30 meter and up. How many aware of the fact that the Elevation Information available in Google Earth can be utilized to get Spot Heights, Contours and DEM? Yes, the 3rd dimension information available in Google Earth can be manipulated to create Spot Heights, Contours and DEM in various GIS software using and small third party app. Below is the link for the tutorial to create Contours and DEM from Google Earth. https://www.youtube.com/watch?v=237pVwC3fNk Note: Few people have asked me that altitude column is not getting updated. That is either problem with the installation or operating system. So try to re install tcx and try. Make sure that internet is connected then you do it. If it still doesn't work, try to do it in different operating system or different computer. Most of the people told it worked after doing this. In the tutorial method is explained using SURFER to get final output. To do the process in ArcMap, follow the tutorial till getting excel file with elevation values, and then follow the other tutorial where it is explained how to create contours using spot heights (already available in the channel.) Elevation information available in Google Earth is also interpolated values, so DEM or Contours extracted are as accurate as Google Earth Values.

Raw GNSS measurements from Android phones. Yep, they are coming. At Google we have been working with our GNSS partners to give application developers access to raw GNSS measurements from a phone. This is really exciting, and marks a new era for our GNSS community. At Google I/O in May, we announced that raw GNSS measurements are available to apps in the Android N operating system, which will be released later this year. This means you can get pseudoranges, Dopplers and carrier phase from a phone or tablet. When can you get it? Well, it will take some time to proliferate throughout the ecosystem, but the first phone that will provide raw measurements will be the Nexus phone that we will launch later this year, and then next year you will see new Android handsets start to support it, as it will become a mandatory feature in Android. At the Institute of Navigation’s ION-GNSS+ conference this September, Frank van Diggelen and I will teach a tutorial where you can learn to access and use these raw measurements. This will be a hands-on course where you collect, view and process raw measurements. You will leave the class with the data, Google software tools, and the knowledge of how to use them. This tutorial is open only to ION-GNSS+ attendees. To register for the conference, visitwww.ion.org/gnss/registration.cfm. source : http://gpsworld.com/google-to-provide-raw-gnss-measurements/

Is there anyone who planned to attend the conference? I really want to give a try with the GNSS. darksabersan.
