  1. done, next time please be more active
  2. extract spectral data using SAGA-GIS

    of course, since you have problem with coordinate/projection on both files , as you explain about image being disappear you cannot extract point value since there are no overlap between the data you need to fix the projection issue first
  3. Hi from Yangon

    welcome Im sure there are some of them
  4. Need to rectify many old aerial photos ?

    first, since you have so many data, you need a batch process to do that. erdas autosync is good since you need to make a lot of geo-referencing data also I think you need combination of software
  5. Purchase ArcGIS for Personal Use

    per year? for people with huge tasks in ArcGIS, worth to buy IMHO
  6. The upcoming features of QGIS 3

    ah, thanx
  7. The upcoming features of QGIS 3

    any exact date for this release?
  8. Remember Intel proc bug? By now you've probably heard about a bug Intel is dealing with that affects processors built since 1995. But according to the people who found "Meltdown" and "Spectre," the errors behind these exploits can let someone swipe data running in other apps on devices using hardware from Intel, ARM and AMD. While server operators (like Amazon) apply Linux patches to keep people from accessing someone else's information that's being executed on the same system, what does this mean for your home computer or phone? Google's Project Zero researchers identified the problems last year, and according to its blog post, execution is "difficult and limited" on the majority of Android devices. A list of potentially impacted services and hardware is available here, while additional protection has been added in the latest Android security update. In a statement, Microsoft said: "We are in the process of deploying mitigations to cloud services and have also released security updates to protect Windows customers against vulnerabilities affecting supported hardware chips from Intel, ARM, and AMD." In a blog post directed towards customers on its Azure server platform, the company said its infrastructure has already been updated, and that a "majority" of customers should not see a performance impact. Apple has not publicly commented on the issue, however security researcher Alex Ionescu points out that macOS 10.13.2 addresses the issue and said that the 10.13.3 update will include "surprises." According to AMD, "Due to differences in AMD's architecture, we believe there is a near zero risk to AMD processors at this time," however it has promised further updates as the information comes out. As for ARM, it says most processors are unaffected but it has specific information on the types that are available here. So what does this mean for you? On your devices the prescription is the same as always -- make sure you have the latest security updates installed and try to avoid malware-laden downloads from suspicious or unknown sources. Update: We've seen a slew of other announcements join the parade, including details from Microsoft on its Windows patches. One thing to be aware of is that the update is only going out if users are running "compatible" antivirus software, so if it doesn't show up for you then that could be the reason. Another consideration is that this attack could be executed via a malicious webpage loaded in your browser, so there's an update for Internet Explorer too. Google noted that turning on Site Isolation in Chrome will mitigate potential attacks, and also said that when it releases Chrome 64 later this month, it will contain protective updates. The folks at Mozilla have confirmed that browser-based attacks are possible, and are taking measures to reduce that possibility starting with version 57 of Firefox. Separately, VMware has updated its products to address the issue. source: https://www.engadget.com/2018/01/03/meltdown-spectre-microsoft-intel-google-apple
  9. yes, stick to LTS is safer, But I dont expect that OS bug will be huge impact to the hardware, like this case, I mean, usually, we only face crash, hang, black screen etc and all can be repaired easily but this, you install buggy OS and suddenly you need to replace your BIOS chip or even RMA your laptop, what a mess
  10. If you find a Lenovo laptop under the tree this xmas, and plan to install Ubuntu 17.10 on it, take my advice and don’t. You heard me: do not install Ubuntu. According to bug reports filed on Launchpad, the official Ubuntu bug tracker, installing Ubuntu 17.10 may inadvertently corrupt the BIOS on a raft of Lenovo laptops, including the Lenovo Yoga line. Which is seriously bad news. Those affected say that after installing Ubuntu 17.10 on their laptops the BIOS on their device is no longer able to save settings (like changing boot order and device, which is often required when dual-booting); that settings reset after a reboot; some are no longer able to exit BIOS; others are left unable boot from USB. BIOS firmware comes pre-flashed on the motherboard. It is the software that gets your system from “off” mode to boot manager (like GRUB) from which an operating system can then load. BIOS software can be re-flashed and upgraded but this is generally not something that most users will be familiar with doing (and it isn’t something that should be done without caution). Naturally, people are not happy about what has happened. “This is unacceptable, right now my Lenovo G50-80 is a brick,” charges one of those affected. “I want my computer to function as it did when I purchased it, in terms of its bios settings and booting from USB is an essential feature” writes another. A Fix is on the Way Thankfully Ubuntu is very much aware the issue. Canonical’s Anthony Wong says the company is “treating this issue very seriously” and is working with Lenovo to find the exact cause. New Ubuntu 17.10 images are also bring prepared which contain an updated kernel that should, fingers crossed, prevent the issue from occurring on new installs (so if you stashed an Artful ISO earlier in the year, make sure you get a fresh one before venturing on) Sadly the updated kernel and Ubuntu image will not fix Lenovo laptops already affected. Lenovo, for their part, is said to have told one Ubuntu users who got in touch that they are not aware of the issue and that no report has been made to them. Their current advice (which goes out to anyone affected by the BIOS corruption issue, I guess) is to …get the motherboard replaced. Ubuntu currently recommend performing BIOS recovery though some other means (if possible), while one user has shared a workaround (of sorts) involving rEFInd to the Lenovo user support page. As a precaution it looks like Ubuntu is planning to disable downloads of Ubuntu 17.10 until it can get the new image, with the new, issue-free new kernel, in situ on its website. In the meantime the best thing for all Linux-loving Lenovo users to do is wait. For more details, workarounds, and irate feedback check out the bug report.
