Files

Numerous files are created and /or used by the data base. Below is a list of the various files.

System Files

Projection.dat; System file to store the projections supported by LISCAD, including installed user projections.

*.FNT; System files which store fonts used by LISCAD.

*.SYM; System files which store the symbols used by LISCAD.

*.LIN; System files which store the line styles used by LISCAD.

Data Base Files

Each group of files refers to a particular data base. Not all of the files will necessarily be present for any particular data base.

.SEE; LISCAD Data Base file from Version 3.2 onwards. LISCAD Lite Data Base file from Version 6.0 onwards.

.LCL; LISCAD Lite Data Base file Version 5.0.

.LDM; Leica Data Manager file Versions 4.x.

.ESP; LISCAD Essential Survey Package Version 3.2.

.HDR; LISCAD Data Base file header pre Version 3.2.

Field Transfer Files

These files are not part of the data base but are used or created by the system when transferring data from the field using the Field Transfer Task.

.RAW Raw File: A file which is created when data is transferred to the system from an electronic data recorder. It contains the raw survey information as transferred as well as a header record identifying the type of data recorder used.

.FLD Field File: A file which is created from a RAW file, or generated via keyboard entry, containing field observations, and which may be used to generate new objects in the data base.

.ADJ Control File: A file which is created from a FIELD file, or generated via keyboard entry, containing control point observations, and which may be used to generate adjusted co-ordinates in the data base.

.TRV Traverse File: A file which is created from a FIELD file, or generated via keyboard entry, containing traverse observations, and which may be used to generate adjusted co-ordinates in the data base.

.TRF Transformation File: A file which is generated via keyboard entry, containing points and co-ordinates on different co-ordinate systems, and which may be used to compute transformation parameters between the co-ordinate systems.

Table Files

These files are not part of the data base but are used to store the settings of code tables and lookup tables which may be used when transferring data to or from the system.

.CTB; Code Table File: A file which stores the settings for a particular code table which may be used when transferring data to the system in the Field Transfer task, or to and from the system in the data conversions task.

.LUT; Code Lookup File: A file which stores the settings for a particular lookup table which may be used when transferring data to and from the system in the data conversions task.

CAD Output Files

These files are not part of the data base but are created via the CAD Output task for transfer to a CAD system.

.CPF; A CAD Output parameter file which stores the CAD Output settings used by the system to create a planimetric CAD file. Refer also to the Concepts/CAD Output topic and the CAD Output Settings commands.

.LPF; A CAD Output parameter file which stores the CAD Output settings used by the system to create a CAD file of long sections

.XPF; A CAD Output parameter file which stores the CAD Output settings used by the system to create a CAD file of cross sections

.SLU; Symbol Lookup File: This is a text used to match LISCAD symbols to DXF Blocks or MicroStation cells.

Each line in the file must contain a LISCAD symbol identifier and a matching foreign system symbol name separated by space=space.

.LLU; Line Style Lookup File: This is a text used to match LISCAD line styles to DXF or MicroStation line styles.

Each line in the file must contain a LISCAD line style identifier and a matching foreign system line style name separated by space=space.

.LCD; A binary LISCAD CAD file for use in the LISCAD CAD module

.DXF; AutoCAD DXF exchange file

.DWG; AutoCAD DWG exchange file

.DGN; MicroStation Design file (PC version)

Data Conversions Files

Numerous exchange files are used or created by the system in the Data Conversions task when transferring data to and from other systems. Refer to the particular Import or Export commands for further information about the associated files.
