Leica 1000Z01 user manual Comments

The data block for a principal point in the file is structured as follows :

11....+KILOMETR 71....+0NEXTGEO 72....+0NEXTRAD

73....+0TEMPLNR 81..10+00000000 82..10+00000000

WI 11 Chainage of the point.

WI 71 Type of the following geometric element.

WI 72 Radius of the next horizontal geometric element, Radius 1 for a compound curve, or the A-Parameter for spirals.

WI 73 Number of a cross-section (Template) assigned to the next geometric element.

WI 74 Radius 2 for compound curves.

WI 81 E-Coordinate of the point.

WI 82 N-Coordinate of the point.

Comments:

•The header consists of a single block at the start of a data file.

•Tangents and the EOP contain “00000NON” in WI72

•Data units in WI’s 11 and 72 are defined by WI81 and WI82.

•If the radius point for a curve (circular or spiral) is to the left of the alignment in the direction of increasing stations, the radius is negative.

•If the radius point for a curve (circular or spiral) is to the right of the alignment in the direction of increasing stations, the radius is positive.

•The same cross section (Template) may be assigned to more than one location.

•An alignment file must contain at least two elements.

•There is no limitation on the size of the Hz-alignment file. As a result, as many data blocks as you like can be entered if a file is created on the PC using the DOS program "ROADDATA.EXE". If a file is created/edited using the program "FILE EDITOR" on the TPS1000 there is a limitation of 200 data blocks.
