Leica GSI
Function
Map360 supports the newer GSI 8 and GSI 16 formats, as well as the older GRE/TRA formats defined by Leica Canada Inc.
Note: Leica System 1200 users should refer to the Leica FDE (Field Data Extractor) topic.
Procedure
When you start the leicagsi command, you will see the following options dialog:
For Leica systems, Map360 supports the following GSI formats and LISCAD Operation Codes:
Leica GSI 8 Format (including Data Pro for LISCAD)
Leica GSI 16 Format (including Data Pro for LISCAD)
Supported Data Pro / LISCAD Operation Codes
If your GSI file includes LISCAD operation codes that you want Map360 to process, then be sure to enable the "Process LISCAD operation codes" checkbox. If your GSI file does NOT include LISCAD operation codes, then this checkbox can be left unchecked. If you are unsure, then enable this option - if your file contains them then they will be used, and if not then this option will not make any difference.
If LISCAD Operation Codes are being processed, you can also specify the coordinate order for Fixed Coordinate records. This option is used ONLY by Operation Code 9 to tell it whether the 43 and 44 words in a fixed coordinate record contain the easting or northing values.
Leica GSI 8 Format (including Data Pro for LISCAD)
We supply this sample to you so you can visually compare it to your file, in case you are either unsure if your file is a GSI 8 collector file, or if you are having problems with the coding. Due to the length of the lines in the collector file, they do wrap around onto the next lines in this sample. Please refer to your collector manual for more information on the formats.

Supported Data Pro / LISCAD Codes
This topic documents the DATAPRO / LISCAD operation codes that may be used when performing field surveys with Leica/Wild data recorders for processing in Map360.
This format uses operation codes for the organization of field data and line connectivity. When field data is recorded using these codes and imported into Map360 via the GSI option, the linework will be automatically drawn on a new layer named LEICADRAWN. Raw observation data is processed into a Map360 traverse file at this time as well.
Operation Code = Leica/Wild Code Block
Feature Code = MicroSurvey description
For METRIC, all distances are assumed to be in millimeters or tenths of a millimeter, as set on the instrument.
For FEET, all distances are assumed to be in tenths or hundredths of a foot.
OPERATION CODE 1 - New Set Up (Before Observation)
Station Point Identifier
Instrument Height
Target Height
Backsight Station Point Identifier - Optional
The backsight station point number must be known at reduction time. If on datum, information block 4 is not used or is set to zero. If a backsight station is set, the next observation will be used to calculate the bearing rotation to be applied to the following observations.
OPERATION CODE 2 - New Target Height (Before Observation)
Target Height
OPERATION CODE 4 - Fixed Azimuth (After an instrument setup)
Fixed Azimuth
Operation Code 4 is always used in conjunction with and immediately after a new set up (operation code 1). These operation codes may be used together in the following methods.
Method 1-Setting an Azimuth to a reference object:
Opcode Info1 Info2 Info3 Info4
1 Station ID Instrument Height Target Height Blank
4 Fixed Azimuth
The first observation after Opcode 4 is interpreted as a backsight to a point of specified fixed azimuth from the station setup point.
This will generate a field file setup code 103
Example:
Opcode Info1 Info2 Info3 Info4
1 1 1.6 1.5
4 90
First Observation is to point 5
Interpretation: The fixed azimuth of 90 degrees is from point 1 to point 5
Method 2-Setting an Azimuth on a traverse leg:
Opcode Info1 Info2 Info3 Info4
1 Station ID Instrument Height Target Height Backsight Point ID
4 Fixed Azimuth
The first observation after Opcode 4 is interpreted as a backsight to the specified backsight point.
The second observation after Opcode 4 is interpreted as a foresight to the next traverse station.
The fixed azimuth entered is the azimuth from the setup station ID to the backsight.
Example:
Opcode Info1 Info2 Info3 Info4
1 1 1.6 1.5 5
4 90
First Observation is to point 5
Second Observation is to point 2
Interpretation: The fixed azimuth of 90 degrees is from point 1 to point 5
OPERATION CODE 5 - New Feature Code (After first observation)
New feature code
When Map360 processes operation code 5, the feature code (and the string identifier which may be contained within the feature code) is processed.
Note: The feature code is set for the previous point and subsequent points until changed.
If the feature code defines a string in the code table, and you wish to end the current string but start a new string with the same feature code, simply use operation code 5 again and enter the same feature code. If
feature code 102 is defined in the code table as a string, the example below would join points 10 through to 12 with a string and then start a new string at point 13 through to 15.
Example: Observation to point 10
Operation Code 5 (enter feature code 102)
Observation to point 11
Observation to point 12
Observation to point 13
Operation Code 5 (enter feature code 102)
Observation to point 14
Observation to point 15
OPERATION CODE 6 - Measured Offsets (After Observation)
Offset +ve right, -ve left (as viewed from instrument)
Added Distance +ve away from instrument, -ve towards instrument
Height Difference +ve up, -ve down
OPERATION CODE -6 – Move Point along Line
Distance
Elevation Flag
If zero is entered for the Elevation Flag then the point will have no elevation. Entering 1 will result in the point taking the elevation of the measured point, while entering 2 will result in a graded elevation being computed between the measured point and the previously measured point.
OPERATION CODE 7 - Circle with Radii (After Observation)
Radius
Radius \
Radius } Optional
Radius /
OPERATION CODE 8 - Line Creation Methods (After first observation)
Line Creation Method
For Line Type 8 (Wings), the following blocks are also used:
Length of wing at start of string
Length of wing at end of string
The number of subsequent points included in the line feature depends on the Line Creation Method selected.
The following Line Creation Methods are supported.
STRAIGHT LINE STRING [Default]
CURVED LINE STRING
CIRCLE BY CENTER AND RADIAL POINT
CIRCLE BY DIAMETER POINTS
CIRCLE BY 3 CIRCUMFERENCE POINTS
CURVE BY 3 CIRCUMFERENCE POINTS
CURVE BETWEEN TANGENT LINES
BUILDING WINGS
Building Wings explanation (Line Type 8):
‘Wings’ of the specified lengths are added to the beginning and end of strings.
The operation code will take affect on the previous observation (if string-able) and any observation following which is string-able.
The operation will continue to run for subsequent strings until terminated with a new line type (Op Code 8) entry. - typically 1 - a straight line.
The format of the code block is:
410028+00000008 42....+00000008 43....+00007500 44....+00007500.
Positive values for the ‘Wing’ will result in them being drawn to the right of the defined line, negative left.
If either dimension is not input, the previous entered value will be taken as the wing measurement. If there has been no value previously entered, the wing length will default to 5 meters.
NOTE: All straight and curved lines which are observed during the operation of a wing will have the defined wings attached.
OPERATION CODE 9 - Fixed Coordinate (Independent)
Point Identifier
North (or East) coordinate
East (or North) coordinate
Elevation
OPERATION CODE 13 - Join points (Anytime after points are defined)
Feature Code
First Point Identifier
Second Point Identifier
Third Point Identifier (optional)
The point identifiers input must have been previously defined.
If the third point is entered, a curve is created, which will also replace that part of any line that is through the same three points with the same code.
OPERATION CODE 14 - Description (After Observation)

Information words 1, 2, 3 and 4 are concatenated into a single description, except where the wildcard "#x" is contained in the Map360 code table description. (x indicates the information word)
If #x is in the code table description, then it is replaced by the corresponding information word.
If #2 is in the codetable description but there is nothing in info 2, the resulting description is truncated after the #1 insertion. Similarly for #3 and #4.
Example:
Code Table Description TREE #1 #2high.
Info 1 ELM
Info 2 2.1
Resulting Point Description TREE ELM 2.1high.
Info 1 ELM
Resulting Point Description TREE ELM
OPERATION CODE 16 - Point on Line (After Line Defined)
New Point Identifier
Starting Point on Line
Ending Point on Line
Distance from Starting Point
OPERATION CODE 17 - Rectangle (After first Point Observed)
Width of rectangle. (Optional)
Width of Step (Optional)
The previous point and the subsequent point will define the base of the rectangle. The rectangle will be formed to the right of its defined base if a positive width is entered, or left if negative. If the first information word is not entered or is entered as zero, then a square will be constructed with all sides equal to the base defined by the two measured points. If "Width of Step" is entered, lines will be drawn within the rectangle parallel to the base.
OPERATION CODE 19 - Remove Elevation from point (After Observation)
The Elevation of the previous observation will be removed. (set to -9999.999)
OPERATION CODE 90 - Split Feature Code and String Identifier
Feature Code
String Identifier
This is an alternative to using operation code 5.
In operation code 5, the feature code and string identifier are entered in a single item in info 1.
Operation code 90 allows the feature code component to be entered in info 1 and the string identifier to be entered in info 2. When Map360 processes operation code 90, the two info words are combined into a single field code containing the feature code and the string identifier.
OPERATION CODE 99 - Ignore last measurement (After observation)
The previous measurement will be marked and passed to the EDM file as a comment only.
