Why restrict the document file format to TIFF?
TIFF is a general document exchange format and the format used since 1993 to store and distribute plan and dealing images from LPI’s Document and Integrated Imaging Management System (DIIMS). TIF images created to LPI specifications are generally of a smaller file size than other formats such as PDF. By adopting TIFF, surveyors are able to complete their plan in the software package of their choice and then create the TIFF image. A TIFF image creates a “snap shot” of the plan (and other documents) and maintains full integrity of the data when viewed in various imaging packages. Other formats such as DXF, DWG or DGN can lose integrity to varying degrees when viewed in different CAD packages. The method accepted is the creation of TIFF images using third party software in the form of raster printer drivers. One successfully trialled by LPI is the Peernet Raster Image Printer (available from www.peernet.com) which converts any document capable of being printed using a Windows application
