Leica WILD
Function
This option reads data in accordance with one of three older file formats defined by Leica Canada Inc. You will be asked to select the 10,20,30 method; the 10-19,20-29,30-999 method; or the TRA file format.
We also support the newer GSI 8 and GSI 16 formats, as well as files downloaded via DXM.
Leica System 1200 users should refer to the Leica FDE (Field Data Extractor) topic.
Procedure
For Leica systems, Map360 supports the following formats:
Leica GRE 10,20,30 Method
Leica GRE 10-19,20-29,30-999 Method
Leica TRA Format
Leica GRE 10,20,30 Method
The Leica translation program will read data in three different formats, all designed by Leica Canada Inc. When you select the Leica option you will be asked whether you wish to read with the 10,20,30, the 10-19,20-29,30-999, or the TRA file methods. The 10,20,30 method was the original method designed by Leica Canada.
Code 10: This code indicates that the next measurement block will contain setup information. The instrument station point number is to be entered as the first code number; the setup description as the second; and the instrument height as the third.
Code 20: This code represents a shot to a backsighted point. The code is followed by a description of the target location, and the target height.
Code 30: This code indicates that shots will follow to foresight points. A code description and a target height must immediately follow this code.
Code 40: This code indicates that side shots will follow, but with a left or right offset. The code 40 is followed by the code description, target height, and a positive or negative offset distance. Negative is left and positive is to the right.
Code 41: This code indicates that side shots will follow. The code is followed by a code description and the target height. If an additional distance is appended, then this distance will be added to the shot distance. This is used for radial shot offsets. If the number is negative, then the slope distance will be shorter; if the distance is positive, the distance will be longer.
The Leica GRE3 and REC module use numbers for descriptions. These numbers can be automatically converted to descriptions through the Description cross reference system. If you enter descriptions in the library, then the numbers will automatically be converted into descriptions. The Leica GRE4 can use either numbers or letters for the codes. In all cases where we refer to number descriptions, the GRE4 letter codes are supported.
A sample file downloaded from a Leica collector is listed below, with comments added in parentheses to clarify how the code numbers are interpreted. Due to the length of the lines shown below, they may wrap around onto the next line.

The Leica data collectors are supported in raw data and coordinate modes. If both modes are available, then both are read from the file. The method of interpretation is further detailed below.
The following types of blocks exist in a Leica file:
Code Record blocks
Code Record blocks describe the data that will follow in the next measurement record (i.e. setup data, backsight, foresight etc). In addition, they may contain description codes, target and instrument heights. Code record blocks contain a "41" in columns 1-2 of the record.
Example:
410004+00000010 42....+00000098 43....+00001567
In columns 12:15 is a code indicator :
Code 10 - Setup data is expected to follow immediately after this record (i.e. the next line in the data collector file must be of type "11" - see Measurement Record Blocks below).
If columns 17-18 contain "42" then columns 26-28 and columns 29-31 are numeric descriptions for posts, manholes, trees, etc. These are cross-referenced with the "Description" table and set to the corresponding point description.
Columns 39-47 contain the instrument height. If the target height was equal to the instrument height previously, then the target height is also updated automatically (i.e. it is still equal to the instrument height).
Code 20 - Backsight data is expected to follow immediately after this record (i.e. the next line in the data collector file must be of type "11" - see Measurement Record Blocks below).
If columns 17-18 contain "42" then columns 26-28 and columns 29-31 are numeric descriptions for posts, manholes, trees, etc. These are cross-referenced with the "Description" table and set to the corresponding point description.
If columns 33-34 contain "43" then columns 39-47 are the new target height.
Code 30 - Foresight data is expected to follow immediately after this record. If columns 17-18 contain "42" then columns 26-28 and columns 29-31 are numeric description types.
If columns 33-34 contain "43" then columns 39-47 are the new target height.
Code 40 - Side shot data is expected to follow immediately after this record.
In addition this record optionally contains the perpendicular offset distances.
If columns 17-18 contain "42" then columns 26-28 and columns 29-31 are numeric post types. These are cross-referenced to the "Description" table, to set the current point description.
If columns 33-34 contain "43" then columns 39-47 are the new target height.
If columns 49-50 contain "44" then columns 55-63 contain the new perpendicular offset to the foresight point.
Code 41 - Side shot data is expected to follow immediately after this record. In addition this record optionally contains the parallel offset distances.
If columns 17-18 contain "42" then columns 26-28 and columns 29-31 are numeric description types.
If columns 33-34 contain "43" then columns 39-47 are the new target height.
If columns 49-50 contain "44" then columns 55-63 contain the new parallel offset to the foresight point.
Measurement Record Blocks
This record type is the RAW data that is downloaded for each shot, and is indicated in the file by having "11" in columns 1-2 of the line.
This record line contains groups of 16 characters. Each group has its own code in the first 2 characters of the group. This code indicates the type of information in this group (Slope distance, Horizontal angle etc).
The group codes are as follows :
21 Horizontal Angle
22 Vertical Angle
31 Slope distance
32 Horizontal distance
33 Vertical distance
81 Easting
82 Northing
83 Elevation
84 Easting
85 Northing
86 Elevation
The record must contain either :
Coordinate data - codes 81,82,83 or codes 84,85,86.
Raw Data - codes 21,22,31,32,33
Both of the above.
If you do not have coordinates, or raw data, then this entire line of data is ignored. You must have each of the codes for the line to be valid. For example, you must have all of codes 81,82,83 or all of codes 84,85,86. You may not have only codes 81,83 in the line (in which case code 82 - the northing - is missing).
Columns 10-15 of the line contain the point number of the shot. This point number is either the setup point, the backsight point, or the foresight point as determined by the last "41" code line (see Code Record Blocks above).
If it is a setup point, then the system attempts to load the coordinates for the point from the MicroSurvey database. If the setup point has not yet been assigned coordinates, the system will use the coordinates downloaded. If downloaded coordinates do not exist either, then the system will prompt you for the values in the coordination program.
If it is a backsight point, then the system attempts to load the coordinates for the point from the MicroSurvey database. If the backsight point has not yet been assigned coordinates, the system will use the coordinates downloaded. If downloaded coordinates do not exist either, then the software will prompt you for the coordinates of the backsight point.
If only coordinates are downloaded (not raw data), then the system saves the coordinates directly to the MicroSurvey coordinate database - but not into the traverse database
If the group begins with "21", then this group contains the horizontal angle. The 6th character of the group is set to "1" for degrees or "2" for grads.
If the group begins with "22", then this group contains the vertical angle. The 6th character of the group is set to "1" for degrees or "2" for grads.
If the group begins with "31", then this group contains the slope distance. The 6th character of the group sets Metric or Imperial units. If the 6th character is:
0 - metric, distances are to be divided by 1000
1 - feet, distances are to be divided by 1000
6 - metric, distances are to be divided by 10000
7 - feet, distances are to be divided by 10000
8 - metric, distances are to be divided by 100000
All the information is stored in the traverse file: the horizontal angle, vertical angle, and the slope distance, plus any non-zero perpendicular or parallel offsets. The data in the traverse file is used later in the coordination program to update the coordinate file to contain the newest coordinates for the point. If Point Protection is on, then the system will compare the new and old coordinates.
Leica GRE 10-19,20-29,30-999 Method
The 10-19,20-29,30-999 method is an improved version of the 10,20,30 method in that it allows the operator to press fewer keys on the total station while still recording the same amount of data.

Leica TRA Format
Leica Canada has a translator to convert the raw data that comes from the GRE or REC module into a very nicely formatted file. They call this a TRA file for translated file. Map360 will also read raw data files in this format. Survey data coded by the 10-19,20-29,30-999 Method can be translated to a TRA file by using the Q3 translator supplied by Leica Canada Inc. The following Leica Canada help file describes this translator. Please contact Leica Canada Inc. for more information on the coding system.
The translator " Q3.exe" translates a simple coding system that is outlined in this help file. Simply type TRA then enter the same filename you used when you downloaded. If you used a gif12 remember to give the filename the extension ".GRE"
If you have recorded angles and distance (11,21,22,31) the resultant ASCII file will read as a field book and be ready for editing by the surveyor. After editing; the file can then be input into a survey software package for processing.
The file will be given the extension .tra and look something like this

If you have recorded co-ordinates (11,81,82,83) the resultant ASCII file will simply be a listing of Pt #, Easting(Y), Northing(X) and Elevation (Z). Should you want labels follow the coding steps outlined below.
This file will be given the extension .yxz and look something like this.

If you have recorded both angles distances and coordinates the software will separate the two and create both files. Nifty Eh!!.

The advantage of the TRA file format is that it is independent of the coding system used. The TRA file has remained the same even with the change from the 10,20,30 system to the 10-19,20-29, 30-999 system.
