(This functionality is available with the Input / Output module)
The system typically requires Leica/Wild GSI measurement data as Point Identifier, Horizontal Angle, Vertical Angle, Slope Distance, PPM (shown in the following standard raw data format),
110011+00000101 21.104+22242470 22.104+09037440 31..00+00030777 51....+0000+000
110012+00000102 21.104+23254540 22.104+09033300 31..00+00028482 51....+0000+000
110013+00000103 21.104+24036260 22.104+09039260 31..00+00027175 51....+0000+000
or as co-ordinates in the following format.
110041+00000210 81..10+01006013 82..10+02084600 83..10+00098255
A longer data line is permitted such that computed co-ordinates can be added to the end of measurement block. The following is a measurement block of such an observation.
110142+00000211 21.104+00538400 22.104+09126370 31..00+00085196 51....+0007+000 81..10+01450500 82..10+00011000 83..10+00012000
These co-ordinates may be extracted directly to the field file if there is no instrument setup or if there are insufficient measurement blocks in the record to re-compute the co-ordinates.
However, if there is a setup and sufficient measurement blocks to re-compute the co-ordinate, then the co-ordinate blocks are not passed to the field file.
This enables data to be collected, co-ordinates computed and used in the field and at the same time retain the ability to reprocess the raw field data in the system.
The measurement data may also be in the form of Point Identifier, Horizontal Angle, Horizontal Distance, Height Difference, PPM. Note however that this form is not valid if operation code 3 (Sets) is used.
Free Coding with Leica Instruments using remark blocks 41 to 44
When free coding with Alpha codes or Numeric codes greater than
100, Remark Blocks 41...44 can be interpreted in two different ways.
This first method allows you to have the feature code and string identifier in two separate blocks.
By having a . or ? character before the Code, Remark Blocks 41...44 are interpreted by LISCAD as:-
41.. Point Feature Code (max 8 characters) e.g. '.POLE'
42.. String Identifier (max 2 Characters) [Optional] e.g. '02'
43.. Symbol Dimension 1 [Optional] e.g. '1.7'
44.. Symbol Dimension 2 [Optional] e.g. '0.3'
Example:
*110017+0000000000000100 81..10+0000000168488736 82..10+0000000395864387 83..10+0000000000033245
*41....+00000000000.POLE 42....+0000000000000001 43....+00000000000001.7
44....+00000000000000.3
This following alternative method allows you to combine the feature code and string identifier in a single block.
If there are no . or ? characters before the Code, Remark Blocks 41...44 are interpreted by LISCAD as:-
41.. Point Feature Code (max 8 characters) + String Identifier e.g. 'POLE02'
42.. Symbol Dimension 1 [Optional] e.g. '1.7'
43.. Symbol Dimension 2 [Optional] e.g. '0.3'
Example:
*110017+0000000000000100 81..10+0000000168488736 82..10+0000000395864387 83..10+0000000000033245
*41....+0000000000POLE02 42....+00000000000001.7 43....+00000000000000.3
Free Coding with Leica Instruments using remark blocks 71 to 74
The following Leica Instrument types support Remark Blocks 71.. to 74..
TPS-100 Series, TPS-300 Series, TPS-400 Series, TPS-700 Series, TPS-1000 Series, TPS-1100 Series, and TPS-1200 Series Instruments.
Remark Blocks are 71..74 are interpreted by LISCAD as:-
71.. Point Feature Code (max 8 characters) e.g. 'POLE'
72.. String Identifier (max 2 Characters) [Optional] e.g. '02'
73.. Symbol Dimension 1 [Optional] e.g. '1.7'
74.. Symbol Dimension 2 [Optional] e.g. '0.3'
Example:
*110000+0000000000000001 81..10+0000000321930149 82..10+0000005808619447 83..10+0000000000000000 71....+000000000000POLE 72....+0000000000000002 73....+00000000000001.7 74....+00000000000000.3
Notes: Remark Blocks 72.., 73.. and 74.. will be ignored if Remark Block 71.. is not present
Symbol dimension 2 (Remark Block 74..) will be ignored if symbol dimension 1(Remark Block 73..) is not defined.
