Each individual description field may be 32 characters long and the total of all the description fields, including commas may be 512 characters long.ġ, 6755.850, 2420.000, 155.398, point2, second description field,third The string record contains the string number, the coordinates of the point and up to 100 point attributes commonly referred to as the description fields and usually referred to as D1, D2, D3 etc. The majority of records in a string file are string records. Z coordinate for the end of the axis record X coordinate for the end of the axis record Y coordinate for the end of the axis record Z coordinate for the start of the axis record X coordinate for the start of the axis record Y coordinate for the start of the axis record This line is used by some functions when extracting sections through a sting file. This is used to store the coordinates of each end of a line which is commonly referred to as the axis line. If it is blank it will have no impact on processing the string file. The field does not necessarily have to contain any data. This field is often modified by various string file processing functions to indicate the functions which have been applied to the file. If it is blank it will have no impact on processing the string fileĬontains a description of the contents of the file. This field does not necessarily have to contain any data. If it is blank it will have no impact on processing the string fileĬontains the date on which the file was last modified. The header record of the string file contains four fields as described below:Ĭontains the location of the file. Spaces only have significance in the text data which may be found in the description fields.Ī sample of a string file is shown below with a detailed description of the various aspects of the string following.Ġ, 6740.000, 2440.000, 152.541, 6830.000, 2440.000, 152.541ġ, 6755.850, 2420.000, 155.398, point2, second description field, third
#Surpac free#
Since the file is comma delimited free format, the number of spaces between fields is unimportant. With the exclusion of the 2 header records and the end of file record, each record represents a point. The string files are free format ASCII text files which use commas "," as delimiters between fields in a record. obs files are now almost redundant and so will not be discussed any further.
#Surpac software#
The reason for distinct names is because of certain software design considerations relating to the software. obs files are exactly the same format internally. String files and Observation files are used to store all coordinate data which is processed by functions which process string data. String Files (.str) and Observation Files (.obs)
