Introduction
SURVIN is a data format conversion process.
How to use
SURVIN requires as input a file of perimeters and/or strings of points that may represent boundaries of planned or actual mine development. The file may have been output from a mine planning process, or digitized from mine plans.

SURVIN |
creates a file containing a record for each unique point within the perimeter file, with associated point attributes, and a file containing the links between points in the same string and the string identification values. The point and segment files may then be used as input to the survey editor to enable interaction of planned development with survey stations and surveyed features, thus allowing listings to be produced of the measurements required by the surveyor to set out excavation lines for operational production control. |

PSYMBOL |
PSYMBOL field value [numeric] to be stored in the point file, representing a point symbol number 91-98, if not found in the perimeter file.(92) Point symbol number 91 : Circle (o) 92 : Cross (+) 93 : Cross (x) 94 : Triangle 95 : Box 96 : Diamond 97 : Star ( ) |

Notes
If two points in the perimeter file are within the tolerance distance
parameter @TOL supplied by the user, it is not duplicated in the output
point file but the link is stored in the string segment file for the string
concerned. The distance between points is computed between their three-dimensional
coordinate positions.
If the input perimeter file does not contain the fields PSYMBOL, PSYMSZE,
P, PTYPE, PCODE, the corresponding parameters must be supplied by the
user, and will be assigned as constants in the output point and string
files.

Error and Warning Messages
|
Message |
Description |
Solution |
|
*** Error - The input file AAAAAAAA is not a valid perimeter file. |
The input perimeter file does not contain the compulsory numeric fields XP,YP,ZP,PTN,PVALUE. Fatal; the process is exited. |
Ensure that the perimeter file &PERIMIN contains the compulsory numeric fields XP, YP, ZP, PTN, PVALUE. |
|
|
|
|
|
*** Warning - Record NN in input perimeter file AAAAAAAA contains absent data for one of the fields XP,YP,ZP,PVALUE. |
This record is ignored. |
Check the data. |
