  1. TESS, the satellite launched by NASA last month that will search thousands of stars for Earth-like exoplanets, has just sent back its first test image. It’s just a quick one, not “science-quality,” but it does give you an idea of the scale of the mission: the area TESS will eventually document is 400 times the area covered by this shot. What you see above is the star field around the constellation Centaurus; this 2-second exposure captured more than 200,000 stars. That’s just in one image from one of the four cameras on board; the Transiting Exoplanet Survey Satellite will employ all four during its mission, watching individual regions of space for 27 days straight over the course of two orbits. Repeated high-resolution imagery of these star fields will let the team on the ground watch for any that dim briefly, indicating that a planet may be passing in between the star and our solar system. This will let it watch far, far more stars than the otherwise similar Kepler mission, which even by looking at only dim stars with a relatively narrow field of view, found evidence of thousands of exoplanets for scientists to pore over. TESS just yesterday received a gravity assist from the moon, putting it near its final orbit. A last engine burn on May 30 will complete that maneuver and the satellite will enter into the highly eccentric, as yet untried orbit designed by its creators. Once that orbit is attained and all systems are go, new imagery will come in about every two weeks when TESS is at its closest point to Earth. “First light,” or the first actual fully calibrated, usable image from the satellite, is expected some time in June. https://techcrunch.com/2018/05/18/nasas-newest-planet-hunting-satellite-takes-a-stellar-first-test-image/
  2. Space-X successfully launched Falcon-9

    SpaceX's launches the new, final version of its Falcon 9 rocket in its ninth flight of this year. Founder Elon Musk says the Block 5 version will be "the mainstay of SpaceX business" moving forward. The new Falcon 9 will be capable of launching over 100 times, with SpaceX aiming for turnaround times of under 24 hours by next year, Musk says. For nearly a decade, SpaceX evolved its Falcon 9 rocket every launch, trying to keep up with lead designer Elon Musk's relentless pursuit of innovation. Until now. An enhanced version of Falcon 9 called Block 5 launched for the first time on Friday. Musk plans for this new rocket to achieve a host of new milestones for SpaceX, including launching and landing the same rocket twice in 24 hours – as early as next year. "We expect [Block 5] to be the mainstay of SpaceX business," Musk said on a conference call with reporters before the launch. Block 5 is the version of Falcon 9 that SpaceX has been working toward since the rocket's debut in June 2010. Nearly twice as powerful as that inaugural Falcon 9 rocket, Musk called Block 5 "the last version" of the orbital class rocket. This is a historical moment for Bangladesh as well because Falcon-9 has carried the first ever telecommunication satellite called "Bangabandhu-1" to the space. Not only that, Block 5 also successfully returned to its drone-ship after the job. Elon Mask is my Tony Stark...
  3. Google will soon launch a new version of Google Maps that will give you more personalized recommendations than before. Google has long worked to make Maps seem more personalized, but since Maps is now about far more than just directions, the company is introducing new features to give you better recommendations for local places. “Today, our users aren’t just asking for the fastest route to a place but also what’s happening around them, what the new places are and what the locals are doing in their neighborhood,” Google VP for engineering and product management Jen Fitzpatrick noted in today’s keynote. The first new feature to enable this is the ‘for you’ tab. This new part of Google Maps will learn from your personal preferences and tell you about what’s new in your neighborhood (or other neighborhoods you are watching). Maybe there’s a new cafe or restaurant. Over the course of the last few years, reviews in Google Maps have also become increasingly important. But what does a four-star review really mean? So going forward, Google Maps will take those reviews and mash them up with what it knows about you to give you a more personalized score based on your context and interests. Another — not AI-related — feature Google is adding to Maps is a new Group Planning feature that’ll allow you to long press on a place and then add them to a shareable list.

  4. It seems the "floating idea" is just a narrow-minded political step to undermine the Clinton/ Obama era. ESA already planned to distribute their high resolution Sentinel images till 2030 and plus decades for free. These data already includes multispectral, RADAR and even hyperspectral images of USA. RS users don't spend like 90's anymore, they use UAVs and tools on the cloud like Google Earth Engine. Just to look back a little, Trump already triggered China to build-up their own semiconductor industry by doing something silly.
  5. Where to sell GIS related Domain?

    Selling contents like data and software which are not yours are very illegal. In 2018 its a waste of time, even if those are yours. If you have quality contents which you think might help others, you should make an online service and sell those to other companies. In that way your contents will remain yours, but people will still get benefitted. Otherwise, get an authentication that the data is yours (ie. a research article may be) and then put everything into public domains. Sooner or later someone else will do the same and steal the spotlight which might be yours.
  6. Map and PowerPoint

    ArcGIS for Office can be an option, even after its buggy interface. For presentation, I don't worry much about putting everything inside powerpoint. Powerpoints should be lightweight and focused at the same time, leaving the technicalities. I start with the bullet points and tables, and later jump to the truly technical session. Since I usually face a lot of eager questions every time I present, I usually leave ArcGIS Desktop and Google Earth open in the background with all maps loaded. For more - "... please talk with me after this presentation". I don't even bother to export, the mighty 'snipping tool' does the job..
  7. The upcoming features of QGIS 3

    At last QGIS v3 Girona is here. Change log Download from here
  8. Detecting plant disease by remote sensing

    I know one initiative who are doing similar project with Wageningen University. They have successfully done few similar work in Natherlands. This project is using Sentinel-2 image and combining that with local weather information to calculate late-blight disease vulnerability index. The project implements IDL and Python to automate the RS analysis. So far I know, this disease is highly dependent on moisture and temperature, and potato fields are relatively easy to identify from RS data. We are doing something similar, but for paddy. There might be some algorithms already which you need to research.
  9. Mutli criteria analysis using Arc Map

    There are no 'best option' for MCDM. Each method has their own pros and cons. Try with something simpler, ie. AHP.
  10. PGSQL Enterpise GDB connection error

    Update (7 Feb): Finally I requested to close the issue, after suggesting the solve to them (which was suppose to the other way around). I hope they note this issue carefully and flag this issue as a bug. I could have done this myself if I'd know how. I am also surprised they didn't immediately have a solution, pokes back and forth once in everyday after lunch (though they immediately asked me if I want to close this issue once I suggested the solve !!). Wish me luck...
  11. PGSQL Enterpise GDB connection error

    The ubuntu apt-get channel currently installs 9.5 version, which I already mentioned. I tried the PGSQL 9.4 as well, with the downloaded files from 'my esri', still no response. Should I try 9.3 as well? 9.3 is still supported (minimum requirement page) for 10.5.1 but not for the 10.6. Update (26 Jan): three days already passed since I asked for a fix and ESRI South Asia couldn't respond. Meanwhile I compiled the exact version of PGSQL (9.5.3) from source, still no luck. Update (31 Jan): They asked me for a teamviewer session which I happily participated. They said, they will 'recreate the linux version of this error and let me know'. I hope they have a linux expert in Singapore or send this to someone at USA. People in ESRI Southasia region - beware. Update (5 Feb): I can't believe they are still 'researching and looking for the solve'. By this time I installed Desktop 10.6 and able to solve this with same file from 10.6's folder. I am not saying anything to these 'engineers'.
  12. Did anyone face this error? I am repeatedly facing this while connecting ArcGIS Desktop to PostgreSQL. I installed the PostgreSQL with apt-get inside an Ubuntu vm. The vm also has Enterprise 10.5.1 installed and configured. The plan is to configure the Portal once this connection is done. I have already tried copying the ST_GEOMETRY file (*.so) for v9.5 (/usr/lib/postgresql/9.5/lib) but that didn't work. Also tried 9.4 and 9.6. Tried both desktop and server files.
  13. The upcoming features of QGIS 3

    Not yet. Probably take some time. Check this blog (2016) and the road map. more: Will QGIS 2.99 and QGIS 3.0 always be the same? Update: 23 Feb is the regular release, LTR coming in 23 June.
  14. The upcoming features of QGIS 3

    Check out the NorthRoadGeo demonstration of the newest features of the upcoming QGIS 3. There’s also a lot of behind-the-scenes changes which they haven’t touched, e.g. a switch to Python 3 and Qt 5 libraries, a brand new, rewritten QGIS server, new QGIS web client, enhanced metadata integration, GeoNode integration, HiDPI support, a cleaner, stabler, easier PyQGIS API, 1000s more unit tests, and so much more. Get the development from here. According to this blog QGIS 3 will take some time to launch, maybe a year or so. Since the project timeline cannot be directly ensured because developer force is largely volunteer based or work according to their own companies agendas, all we can do now is to wait and try the latest builds.
  15. Ubuntu 17.10 Breaks the BIOS on Some Lenovo Laptops

    Somehow I find both of this two thing a bit edgy. I have seen two very good looking Lenovo pc going down in just a year of light use. Though I've used W530 happily for myself for over 3 years, except for some graphics issues. I also stopped experimenting new releases of Ubutnu and settled with the LTS. Unlike many other brands Lenovo use to customize their own driver software to fit their machines. This is problematic for third party manufacturers (ie. Realtek) and even open communities to easily track any hardware issues. The best thing I think is to consult with the Lenovo requirement webpage of their pcs and stick with that. And marry xmas to everyone.
