Mariappan and B. Parthasarathy Dept. of Master of Computer Appl., Mailam Engg. College, Mailam-604 304, Villupuram Dt., Tamil Nadu, India [email protected] Abstract: The present work focuses on the analysis and results. The digital entities are images of reality, stored as examination of different types of file format system, data (bits) that must be interpreted for display by applying storage devices and storage & retrieval systems which information and knowledge. The preservation of digital are most frequently used in the various applications. It is entities requires the ability to characterize data, focused on the file format to identify the right file to right information, and knowledge (Regan W. Moore, 2000). applications for the fast storing and accessing speed with Data integrity is a fundamental aspect of storage less memory space along with the suitable file format on security and reliability. The reliable access to data is specific storage devices, RAM and processors. The prerequisite for most computer system and applications. analysis evolves based on different types of file format on File system consistency is one of the common ones. different storage devices taking into account different Data storage patterns are being employed for efficient research perspectives. The outcome of the work retrieval of data from secondary storage devices motivates multimedia applications users and developers (Gopalan Sivathanu et al., 2005). for choosing appropriate file format, storage devices, It is meant to operate in a COMOHO (commercial RAM and processors to undertake their applications in a office, mobile office, and home office) environment, i.e. successful manner. computing anywhere, anytime.

  • 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.

  • 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.

  • Image Formats
    Image Formats Ioannis Rekleitis Many different file formats • JPEG/JFIF • Exif • JPEG 2000 • BMP • GIF • WebP • PNG • HDR raster formats • TIFF • HEIF • PPM, PGM, PBM, • BAT and PNM • BPG CSCE 590: Introduction to Image Processing https://en.wikipedia.org/wiki/Image_file_formats 2 Many different file formats • JPEG/JFIF (Joint Photographic Experts Group) is a lossy compression method; JPEG- compressed images are usually stored in the JFIF (JPEG File Interchange Format) >ile format. The JPEG/JFIF >ilename extension is JPG or JPEG. Nearly every digital camera can save images in the JPEG/JFIF format, which supports eight-bit grayscale images and 24-bit color images (eight bits each for red, green, and blue). JPEG applies lossy compression to images, which can result in a signi>icant reduction of the >ile size. Applications can determine the degree of compression to apply, and the amount of compression affects the visual quality of the result. When not too great, the compression does not noticeably affect or detract from the image's quality, but JPEG iles suffer generational degradation when repeatedly edited and saved. (JPEG also provides lossless image storage, but the lossless version is not widely supported.) • JPEG 2000 is a compression standard enabling both lossless and lossy storage. The compression methods used are different from the ones in standard JFIF/JPEG; they improve quality and compression ratios, but also require more computational power to process. JPEG 2000 also adds features that are missing in JPEG. It is not nearly as common as JPEG, but it is used currently in professional movie editing and distribution (some digital cinemas, for example, use JPEG 2000 for individual movie frames).

  • File Format Identification and Validation Tools Roy Lechich 2/2007 Integrated Library & Technology Systems Yale University Library
    File Format Identification and Validation Tools Roy Lechich 2/2007 Integrated Library & Technology Systems Yale University Library File Types and Formats With the increasing uses for software, many of them involving storage of different kinds of data, numerous types of computer files have emerged. In fact , it is virtually impossible to list every type of computer file, because: • some file types are general while others are very specific • some file types are widely used while others may exist only for the use of one organization or individual • the specfications for some file types are proprietary while others are open • new types are always being created. A file type often has an associated explicit format specification -- a formal declaration of how information is to be encoded in a file to qualify as being of that "type". The more widely used and specific a file type is, the more likely that it will have a corresponding format specification, with its formal declaration existing as a "reference implementation" and usually maintained by a standards organization. Key file use concepts: • different types are typically created, accessed and modified by some set of programs or tools – this can range from very general (e.g. text files able to be read and written by operating system tools) to very specific (e.g. a jpeg 2000 requiring a very specific program to create or view the image). • users of a specific file will do so using these appropriate programs/tools File Type Identification vs. File Format Validation Most people typically are not overly concerned about file formats and related issues, because a) they are happily able to create and use their data with their sets of applications and tools, and b) they do not need to think about the implications of the passage of time upon their data and their ability to continue to use it.

  • Best Practices for File Naming and Organizing
    Smithsonian Data Management Best Practices Naming and Organizing Files Name and organize your files in a way that indicates their contents and specifies any relationships to other files. The five precepts of file naming and organization: Have a distinctive, human-readable name that gives an indication of the content. Follow a consistent pattern that is machine-friendly. Organize files into directories (when necessary) that follow a consistent pattern. Avoid repetition of semantic elements among file and directory names. Have a file extension that matches the file format (no changing extensions!) FILE NAMING A file name should enable disambiguation among similar files and, for large numbers of files that make up a dataset, facilitate sorting and reviewing. Ideally, file names should be unique. Keep in mind that files can be moved and, without the inherited folder structure, important descriptive information about the contents could be lost. Consider whether a filename would be meaningful outside of your chosen directory structure, and if not, how important the loss of that context would be, e.g., if the date a file was created is important, include it in the filename rather than just the directory name. To provide a description of the file contents in the name itself, you should include elements such as: a date, or at least the year, the contents of the file were created, in the YYYYMMDD format (four digit year, two digit month, two digit day.) o start the filename with the date if it is important to store or sort files in chronological order. the project name, or documented abbreviation for the project.
