Write Landmark File

Landmark uses two dump files, the $$C for coordinates and $$L for Lots

Output File
Enter the name of the Landmark output files. These files generally have a .$$C and .$$L extensions. The program will write out all the points and strings from the current job.

Select Points/Layers
You can select the layers to be written, the range of point numbers, the sheet number or a centroid point and a radius. Any of these methods can be used in combination to select a ‘set’ of points to be written to the output file.

Layer Code Translation
This field displays the number of points and Layers currently selected for output

$$L File Format
At the start of the file job limits are given in the $MINMAX record, followed by a summary of the layers with a $SUM record for each layer in the job.

The MINMAX and $SUM records are not essential as LANDMARK can create them after the transfer file has been read in

Each lot or string has a header(LOTS) as follows:
LOTSLot Number, Lot type, Centroid X, Centroid Y, Area
This is followed by a Layer definition($LAY) as follows:
$LAYLayer name ;layer setting switches

The layer switch settings are:

No	Use	Meaning
1	ON/OFF/TAG	0=Lot OFF 1=Lot ON 3=TAG 4=Tag2
2	DIST:	0=OFF - Not Plotted 1 to 9 Pen Number for Distance
3	BEARING:	0=OFF - Not Plotted 1=Bearing Spread 2=Bearing short
4	ARC	0=OFF - Not plotted 1=Chord Table 2=Arc only 3=Arc,chord distance and bearing 4=distance with brackets around it
5	LOT	0=OFF - Lot Number is not plotted 1 to 9 Pen number for Lot Number
6	AREA	0=OFF - Lot Area is not plotted 1 to 9 Pen number for Lot Area
7	POINTS	0=OFF - Point Numbers are not plotted 1 to 9 Pen number for Point Numbers
8	PEG	0=OFF 1 to 6 coded radius fir circles at pegs 1=0.4mm, 2=0.6mm..... 6=1.6mm
9	PMS	0=OFF 1=Plot double circle at peg
10-11	LINE	0=No Lot lines plotted 1 to n Pen number for lines
12-13	LINE TYPE	0=No lines plotted 1 to nLine type for lines
14	RAD	0=OFF no lines drawn 1=Line only drawn 2=Line and bearing Note: For plotting, the centre point POINT ENTITY RAD must be ON
15	CHAIN	0=Off no chainage plotted 1= chainages at intervals 2- TP chainages
16	COORD	0=OFF None 1=All points X,Y,Z,CODE to Coordinate Table 2=First point of lot to coordinate table 3=All points X,Y,Z to coordinate table
17	BREAK	0=OFF No adjustments to contours 1=Adjustments to contours 2=DELTRI can be used to trim job
18	CURVES	0=Curves defined by Centre of circle 1=Curves defined by Points on the curve 19 to 28 are not used and should be set to 0

The $LAY record is followed by a point record for each point.
Each point record is as follows:

Columns 1 to 7	Point Number
8	C for centre point
10	to 18YYYYYYYYY
19	to 33X coordinate
34	to 48Y coordinate
49	to 62Z coordinate

If there is no Z coordinate, this is set to -9999.0000
A typical file output by LANDMARK looks like this:

The $$L lot entry switches used are:

Switch	Value	Meaning
11Lot ON
21Pen for Distances
32Use Short style for bearings(no tabs between DMS)
43Display arc and chord bearing and distance
51Pen number for lots
61Pen for area
70No point numbers
80No Pegs
90No PM's
