  • The LAS File Format Contains a Header Block, Variable Length
    LAS Specification Version 1.2 Approved by ASPRS Board 09/02/2008 LAS 1.2 1 LAS FORMAT VERSION 1.2: This document reflects the second revision of the LAS format specification since its initial version 1.0 release. Version 1.2 retains the same structure as version 1.1 including identical field alignment. LAS 1.1 file Input/Output (I/O) libraries will require slight modifications in order to be compliant with this revision. A LAS 1.1 Reader will read LAS 1.2 (without the new enhancements) with no modifications. A detailed change document that provides both an overview of the changes in the specification as well as the motivation behind each change is available from the ASPRS website in the LIDAR committee section. The additions of LAS 1.2 include: • GPS Absolute Time (as well as GPS Week Time) – LAS 1.0 and LAS 1.1 specified GPS “Week Time” only. This meant that GPS time stamps “rolled over” at midnight on Saturday. This makes processing of LIDAR flight lines that span the time reset difficult. LAS 1.2 allows both GPS Week Time and Absolute GPS Time (POSIX) stamps to be used. • Support for ancillary image data on a per point basis. You can now specify Red, Green, Blue image data on a point by point basis. This is encapsulated in two new point record types (type 2 and type 3). LAS FORMAT DEFINITION: The LAS file is intended to contain LIDAR point data records. The data will generally be put into this format from software (e.g.

  • Powershell Scripting Language Course Proposal for Tallinn University of Technology
    TALLINN UNIVERSITY OF TECHNOLOGY School of Information Technologies Riivo Kiljak 178071IABM POWERSHELL SCRIPTING LANGUAGE COURSE PROPOSAL FOR TALLINN UNIVERSITY OF TECHNOLOGY Master’s thesis Supervisor: Siim Vene MSc Tallinn 2019 TALLINNA TEHNIKAULIKOOL¨ Infotehnoloogia teaduskond Riivo Kiljak 178071IABM POWERSHELLI SKRIPTIMISKEELE KURSUSE ETTEPANEK TALLINNA TEHNIKAULIKOOLILE¨ Magistrito¨o¨ Juhendaja: Siim Vene MSc Tallinn 2019 Author’s Declaration of Originality I hereby certify that I am the sole author of this thesis. All the used materials, references to the literature and the work of others have been referred to. This thesis has not been presented for examination anywhere else. Author: Riivo Kiljak 07.05.2019 3 Abstract In the thesis, a recommendation is made to establish a new course at TalTech. The course is intended to teach the PowerShell scripting language to students, most importantly in the IT Systems Administration programme. Course material is proposed in the form of lecture slides, home assignments and knowledge tests. All three of which are available in the appendices of the paper. Design science is used to pass iterations of improving the content prior the the paper publishing. Academic literature is analysed to determine the included and excluded topics and the teaching methodology. More- over, input is acquired from scrutinising public information on Microsoft’s official PowerShell courses and interviewing subject matter experts who use PowerShell at local companies. The course material is provided written in LATEX which means that it can be conveniently modified, version controlled and distributed in the PDF format. Although the proposed course is seen as an online course hosted on Moodle, argumentation is made suggesting a combination with classroom seminars is likely to result in better learning outcomes at the cost of scalability.

  • CONESTOGA CABINET ASSEMBLY INFORMATION What Is Included with Your Cabinets: What Is Not Included with Your Cabinets
    CONESTOGA CABINET ASSEMBLY INFORMATION We suggest you view the 4 minute assembly demonstration video on our web site to see how easily our high end custom cabinets are assembled. Before continuing, it is important to realize that Conestoga’s RTA cabinet is targeted at cabinet shops who would rather use this system than build their own custom cabinets from scratch. On one hand, this indicates that it’s a VERY high quality cabinet. On the other hand, it means Conestoga has made some assumptions that its user has certain level of cabinet making skills and knowledge which most homeowners may not possess. As a result, we feel the assembly instructions Conestoga details in their guide are incomplete. Therefore, we have compiled the following assembly information from our years of assembly experience with this product. Remember, as opposed to other Conestoga Re-sellers or sales agents, we actually use the product every day. So, if you have a question that is not answered here, just give us a call and we can talk you through it, send you images from our shop floor, diagrams or even helpful hardware items to assist you. If it gets frustrating, take some time away and give us a call or shoot us an email. Rest assured, we’ll get you through it! What is Included with Your Cabinets: Everything necessary to build the cabinet box. Drawer glides and necessary hardware/screws. Hinges and necessary hardware/screws. Doors, drawer fronts and drawer boxes. What is not included with Your Cabinets: Screws required to mount drawer fronts to the drawer boxes (we use self tapping wood screws 1-1/4” long, available at local home centers or hardware stores.

  • Solve Errors Caused by Corrupt System Files
    System File Corruption Errors Solved S 12/1 Repair Errors Caused by Missing or Corrupt System Files With the information in this article you can: • Find out whether corrupt system files could be causing all your PC problems • Manually replace missing system files using your Windows installation CD • Use System File Checker to repair broken Windows system files • Boost the memory available to Windows File Protection for complete system file protection Missing or corrupt system files can cause many problems when using your PC, from cryptic error messages to mysterious system crashes. If one of the key files needed by Windows has gone missing or become corrupt, you may think that the only way to rectify the situation is to re-install Windows. Fortunately, nothing that drastic is required, as Microsoft have included several tools with Windows that allow you to replace corrupt or missing files with new, fresh copies directly from your Windows installation CD. Now, whenever you find that an important .DLL file has been deleted or copied over, you won’t have to go to the trouble of completely re-installing your system – simply replace the offending file with a new copy. Stefan Johnson: “One missing file can lead to your system becoming unstable and frequently crashing. You may think that the only way to fix the problem is to re-install Windows, but you can easily replace the offending file with a fresh copy from your Windows installation CD.” • Solve errors caused by corrupt system files ...................

  • Common Object File Format (COFF)
    Application Report SPRAAO8–April 2009 Common Object File Format ..................................................................................................................................................... ABSTRACT The assembler and link step create object files in common object file format (COFF). COFF is an implementation of an object file format of the same name that was developed by AT&T for use on UNIX-based systems. This format encourages modular programming and provides powerful and flexible methods for managing code segments and target system memory. This appendix contains technical details about the Texas Instruments COFF object file structure. Much of this information pertains to the symbolic debugging information that is produced by the C compiler. The purpose of this application note is to provide supplementary information on the internal format of COFF object files.
