    Klau Geomatics has released Real-Time Precise Point Positioning (PPP) for aerial mapping and drone positioning that enables 3 to 5 cm initial positioning accuracy, anywhere in the world, without any base station data or network corrections. With this, you Just need to fly your drone at any distance, anywhere. The system allows to navigate with real-time cm level positioning or geotag your mapping photos and Lidar data. You don’t need to think about setting up a base station, finding quality CORS data or setting up an RTK radio link. You don’t need to be in range of a CORS station, you can fly autonomously, in remote areas, long corridors, unlimited range, it just works, giving you centimetre level accuracy, anywhere. Now, with this latest satellite-based positioning technology, 3 to 5cm accuracy can be achieved, anywhere in the world, with no base station. KlauPPP leverages NovAtel’s industry-leading technology to achieve this quantum leap in PPP accuracy. NovAtel PPP and Klau Geomatics hardware/software system is now the simplest, most convenient and accurate positioning system for UAVs and manned aircraft. The bundled solution enables accurate positioning in any published or custom coordinate system and datum. This technology is very applicable to surveying, mapping, navigation and particularly the emerging drone inspection industry, starting to realize that absolute accuracy is essential to analyze change over time in 3D assets. A BVLOS parcel delivery drone can now travel across a country and arrive exactly on it’s landing pad. No range limitations, no base station requirements or radio links. Highly accurate autonomous flight. Large scale enterprise drone companies can deploy their fleet of operators with a simple, mechanical workflow to capture accurate, repeatable data, without the complications of the survey world; of RTK radio links and network connections or logging base station data within a range of each of their many projects. Now they have a simple consistent operation that just works, every time, every location. “Just as Klau Geomatics led the industry from RTK and GCPs to PPK, we now lead the charge to PPP as the next technology for simple, accurate drone operations”, says Rob Klau, Director of Klau Geomatics source : http://geomatics.com.au/

    Taking picture of a stranger has become easier though (oh I was just using the map, lady !!). 😉

    see here : https://gis.stackexchange.com/questions/62624/questions-regarding-the-processing-of-mosaic-landsat-8 here the link that compare both method : http://www.faqs.org/faqs/sci/Satellite-Imagery-FAQ/part3/section-14.html some people prefer to mosaic first and then analysis like me, and some prefer analysis first and then mosaic you may read to see the differences and make a decision

    Thank you Mr. Moderator! This seems to be an interesting place to check out GIS related discussions. Please give me a few days to roam around 🙂 One prominent use of GIS in the UAE is that of Abu Dhabi Municipality, for land registration purposes. Let us see what I can pitch in

    Hi Darksabersan, the links are dead, could you reactivate and perhaps upload to a different site like Mega.nz, please? thanks

    Spectral Python (SPy) is a pure Python module for processing hyperspectral image data. SPy has functions for reading, displaying, manipulating, and classifying hyperspectral imagery. SPy can be used interactively from the Python command prompt or via Python scripts. SPy is free, open source software distributed under the GNU General Public License. To see some examples of how SPy can be used, you may want to jump straight to the documentation sections on Displaying Data or Spectral Algorithms. You can download SPy from the SPy Project Page hosted by Sourceforge.net. Install SPy http://spectralpython.sourceforge.net/installation.html User Guide http://spectralpython.sourceforge.net/user_guide.html
