    Hi, Pixel size will solve the problem of scale, How about the rotation problem? Is that Azimuth angle? It seems like an imagery from a water body with an elevation near to zero. do you have the elevation of the camera (1114.1 meters?)? and size of the image? is it tilted?

    System.Drawing.Image img = System.Drawing.Image.FromFile (@"my image.jpg") now you have img.Width and img.Height

    you have to move center of your image which is not georeferenced to the exact location, this is the movement problem and your question about pixels and cm, think about a resolution (100,100) with 2 different pixel sizes 1 - 1*1 cm2 2 - 1000*1000 cm2 do you think calculation in pixels is correct now?

    I don't have any documents, unfortunately. convert your image into an array. find the x y of the center of the image for example (10 cm, 12 cm) convert them to degrees dx = Long - Xdeg dy = Lat - Ydeg A = move all the cells with this dx and dy B = rotate A (flight azimuth) C = scale B based on flight height and .. (i'm not sure about dz)

    As far as I know, yes you can you have image size, camera elevation, camera focus length, so you can solve Scale problem, you have flight azimuth, so you can solve Rotation problem if you have delta X, delta Y and delta Z, so you can solve Movement problem.

    I dont know about that. But there is another angle on the top right of the image. I dont remember these courses but my guess is information on top are about flight and on the bottom are about camera settings!!

    Dear rahmansunbeam, Thanks for your answer, you know the only data that I have are as this image. I think I can not find 4 points as I dont have any other benchmarks except what is in center of the image. I think If I can find pixel size on earth I can find other points but the rotation is the case here. https://ibb.co/ehscRQ The image that I have is uploaded in above link. Can you please take a look at it and give me some suggestions?thanks

    You have to identify 4 more points from the xy location. Just set a fixed euclidean distance from that point and draw four other point who have same distance from their neighbors. The distance should not exceed the image size. Than let the program identify their xy locations. More ideas are here - Georeferencing aerial photos when only centroid is known using ArcGIS for Desktop or ERDAS Imagine? I think you cannot do it with elevation.

    NASA launched an updated image and video library website with their entire archive at the fingertip. The new website does not need you to enter which archive you want to browse, is it Cassiny, or Hubble, or JPL. Check this out. Full resolution version of the image above

    Hi guys I was about to give a link to three GIS Virtual Machines that I purchased, but now have decided to create my own based on Ubuntu Server 16.04. I plan the following versions: 1. PostGIS and GeoServer 2. PostGIS and MapServer, and 3. PostGIS and QGIS Server Besides these packages, and dependencies, there will also be Shellinabox, and Samba. PostGIS will also include a couple of extra extensions like Pointcloud, PgRouting and FDW. I would like to know if there are any interest in this from the community? I will do this if there is enough interest. I would also like to know about any special requests that you might have, like other GIS Servers (for instance include GeoNode), or another Operating System like Centos. Pieter

    Thanks in advance. I would recommend creating a lightweight and headless vagrant box, there are no good box currently available like this. Lubuntu might me a better option.

    Windows 10 latest big update called 'Creators update' has been released. After much tweaking and fixing, the new creators updated brings a lot of new tool for everyone to try. Take a look at the special features it has. Cortana setup If you are setting up windows for the first time, you'll now meet Cortana to guide you to the setup process. The entire process of setting up Windows 10 has been greatly simplified, especially if you compare it to how long and complicated it took to get a Windows Vista machine ready just 10 years ago. Game mode Microsoft is focusing on improving the gaming experience in Windows 10 Creators Update. A new Game Mode in the Xbox app will prioritize CPU and GPU resources for a game. It’s designed to reduce background tasks and other apps from hogging all the system resources, and ultimately make sure that games run as best as they can on a Windows 10 PC. Microsoft has also added Beam streaming (similar to Twitch) to the Xbox app for Windows 10, so all users have the ability to stream their gaming sessions to friends. Game Mode will need to be enabled on a game-by-game basis, but publishers should be able to enable it automatically in the future. Game Mode is enabled by default in Windows 10 Creators Update. Picture-in-picture Microsoft is adding picture-in-picture support to its Universal Windows Apps. The built-in Movies & TV app allows you to watch a film or TV show and pop the window out so it’s always on top, and Skype will place calls above other windows. It’s similar to features on iOS or Android, and you can keep watching content while you browse or work in other apps. Only some of Microsoft's own apps support picture-in-picture right now, but all developers will be able to include the feature in app updates. Night light Microsoft has built its own version of F.lux into Windows 10 with the Creators Update. Dubbed Night Light, you can allow Windows 10 to reduce blue light from a screen after sunset or at a specific time in the evening. It’s much like what’s already available on iOS, macOS, and Android, but at least you don’t need a third-party app to enable this on Windows anymore. Dynamic Lock Dynamic Lock is a new Windows 10 feature that’s designed to be the opposite of Windows Hello. Known internally at Microsoft as “Windows Goodbye,” Dynamic Lock lets you automatically lock a Windows 10 PC when you’re away from it. You can pair Bluetooth devices like a phone or wearable, and Windows 10 will sense once the Bluetooth connection is too far away and lock the PC. Paint 3D Microsoft’s Creators Update for Windows 10 is designed with 3D in mind. Although there aren’t many creative features in the OS update generally, Paint 3D is the obvious addition. As the name suggests, it’s a 3D version of Microsoft’s built-in Paint app, and it’s totally rebuilt and modern. You can build 3D objects in Paint 3D or import ones created by community members from Remix 3D. It’s also a lot more touch-friendly than the regular Paint app, and you can use a stylus like the Surface Pen to annotate and create objects. Once you’re finished with a Paint 3D creation, it can easily be shared to the Remix 3D site or even used on a Windows Mixed Reality headset or HoloLens. Windows photos Although it’s not strictly a Windows 10 Creators Update feature, Microsoft has updated its Photos app recently to support inking. It’s a much-needed addition that lets you pick a photo and annotate it and share it easily via email or social networks. Unfortunately, inking in Windows 10 Creators Update still isn’t everywhere. Even in apps like the built-in email client, you can’t simply jot notes down inside an email or annotate an attached image. Microsoft has a long way to go to bring inking to the center of Windows 10, but features like inking in the Photos app and Windows Ink are a sign it might eventually happen. Windows Hello One surprising addition to the Windows 10 Creators Update is the fact that Windows Hello gets faster. Microsoft has improved the recognition process for facial scanning, and the new setup process shows you exactly how Windows Hello scans your face to detect who you are. The result is a much speedier Windows Hello login process. Edge Microsoft is tweaking its Edge browser with the Creators Update. A new feature lets you set tabs aside and save them for use later on. It’s essentially a method to save a snapshot of your current browser window. If you’re a heavy user of tabs then it’s a welcome feature, but for everyone else the new buttons that enable the feature are likely to be confusing. Microsoft is also adding ebook support and the ability to view 360 videos to Edge. You can download and purchase ebooks through the Windows Store, and sample 360 videos are available in the Movies & TV app. Updates and privacy One of the smaller changes in Windows 10 Creators Update will have a big impact for those wishing to better control updates. You can now pause updates for a week, or configure active hours in Windows 10 for up to 18 hours a day. This should reduce complaints about Windows 10 automatically rebooting machines for updates, and provide the ability for users to control them better. Microsoft is also tweaking its privacy controls in Windows 10 Creators Update. You’ll be prompted to review and configure features like diagnostics, speech recognition, location, and relevant ads. It’s part of Microsoft attempts to be more transparent, and a response to some widespread criticism over Windows 10’s privacy controls. Overall, the Creators Update doesn't have a lot in it and isn't nearly as comprehensive as last year's Anniversary Update. Microsoft has another major update planned for later this year, which should include a lot of notable new features and design improvements. Download the update Source - The Verge, The Microsoft blog

    I would just read the posts from that site would help, then contact the guy that did it Quote " mwillis I probably need to write a blog post to cover all the details of how I did it but here is the short version. I imported a DEM into ArcGIS and generated contours and a raster showing the extent of the vegetation (green on map). That was all exported as a raster with the same dimensions as the DEM in X and Y directions. In 3DS Max, the same DEM was imported and turned into an editable poly. I used a number of splines that conformed to the surface of the DEM/poly to create the paths for the animations. Finally, I textured the DEM with the raster from ArcGIS and animated the arrows and cylinders (animals and hunters) along the paths. That was all exported as an FBX for upload into Sketchfab. Sketchfab gives the average user a way to experience this data in a way that’s impossible elsewhere."

    INTRODUCTION Web mapping focuses on disseminating and processing geographic information by means of Internet and World Wide Web. Combination of the web and GIS (Geographic Information Systems) has unlocked the potential of GIS, and put online maps and geospatial intelligence in the offices/homes of millions and the hands of billions. The increasing flexibility and interoperability of web mapping technologies has opened new opportunities for Web Based Mappers. Both non-GIS users and GIS experts can do more now, than ever to share maps over the internet. Web maps can easily deliver up to date information,maps are generated automatically from databases, and they can display information in almost real-time. They don't need to be printed, mastered and distributed. Web GIS has immense applicability to e-government, e-business, e-science, and all aspects of daily life. Government employees can utilize Web GIS to improve public services delivery and boost collaboration across agencies.Regardless of the sector, businesses can use Web GIS to enhance their existing business models and create new ones. Researchers can find new solutions to meet the challenges of the new frontiers. Web GIS has great practical value to our world today and into the future. WHO SHOULD APPLY? Non GIS Users, GIS experts, Cartographers, Geographers, Geoscientist, surveyors, Planners, Database administrator, system administrator, IT expert, software engineers, M&E expert. REQUIREMENTS No prior knowledge of GIS is required. DURATION 10 days LEARNING OBJECTIVES To understand the importance of web services and to give you some experience making web maps with FOSS and open standards Acquire skills how to make different types of web map Understanding spatial databases Learn how to publish maps online using open source software (Carto DB, fusion Tables, Geoserver). Able to Read Data from various Data source Processing spatial data with FOSS Drawing and querying maps on the server using Web Map Service Putting layers together with a web mapping API Learn how to Explore open data, VGI, and crowdsourcing
