Structure and samples of MTRCREA.IMH file

Top

Auxiliary  text  file file defines objects used to create elevation matrix.  It contains  foollowing  sections :

- file descriptor MTRFILTER;

- list of objects with semantic characteristic Absolute elevation  ABSOLUTE_HEIGHT_OBJECTS;

- description of objects with depths HYDROGRAPHY_ISOBATH;

- list of objects with semantic characteristic Relative elevation RELATIVE_HEIGHT_OBJECTS;

- list of hydrography area objects with constant elevation (water surfaces) HYDROGRAPHY_CONSTANT_HEIGHT_OBJECTS;

- list of hydrography linear objects with varied elevation (drainage lines) HYDROGRAPHY_VARIED_HEIGHT_OBJECTS;

- list of additional semantics  ADDITIONAL.

File descriptor (MTRFILTER) contains  keyword  WHAT_IS_IT, any string may be its value.

List of objects with semantic characteristic Absolute elevation      

 

ABSOLUTE_HEIGHT_OBJECTS  contains :

- mode of list objects processing CODES (CODES=INCLUDE  defines  including of  objects  to matrix creation, CODES=EXCLUDE defines excluding of object  from matrix creation) ;

- count  of  objects in the list COUNT;

- objects of the list, defined by keywords CODn,  n – number of object in the list.   Value of          

- code of  semantic characteristic Absolute elevation ABSOLUTE_HEIGHT_CODE;

- sign of use of "absolute height" semantic characteristic  ABSOLUTE_HEIGHT_SIGN;

ABSOLUTE_HEIGHT_SIGN;

- keyword CODn  is string,  which contains code, key and name of object.  Name of object   may be missed.

 

Description of objects with depths HYDROGRAPHY_ISOBATH contains:

- code of semantic characteristics "depth" DEPTH_CODE;

- code of a pool (the seas, lakes) SEA_CODE;

- code of isobath ISO_CODE;

- code of marks of depth PNT_CODE;

- mode «Get the level of pool from its semantics absolute height» GET_ABS_SEA_LEVEL_FROM_SEMANTIC;

- value of pool's level in meters ABS_SEA_LEVEL;

- mode «Process objects with depths» DEPTH_PROCESS.

 

Objects list with relative height "RELATIVE _HEIGHT_OBJECTS" contains:

- RELATIVE _HEIGHT_CODE - code of semantic characteristic " relative height ";

- CODES - inclusion sign of list objects into processing  (CODES=INCLUDE - it means inclusion of the list objects into processing, CODES=EXCLUDE - it means exception of the list objects out of processing);

- COUNT - quantity of objects in the list;

- list objects, represented by keywords CODn and DEFn, where n - number of the object  in the list. Value of the keyword CODn it is the string containing code, key and name of the object. The object name can be missed. Value of the keyword DEFn it is the default value of relative height for the object with number "n".

 

The list of area's objects of hydrography with constant height HYDROGRAPHY_CONSTANT_HEIGHT_OBJECTS contains:

- COUNT - quantity of objects in the list;

- list objects, represented by keywords CODn, where n - number of the object in the list. Value of the keyword CODn it is the string containing code, key and name of the object. The object name can be missed.

 

The list of linear objects of hydrography with variable height HYDROGRAPHY_ VARIED _HEIGHT_OBJECTS contains:

- COUNT - quantity of objects in the list;

- list objects, represented by keywords CODn, where n - number of the object in the list. Value of the keyword CODn it is the string containing code, key and name of the object. The object name can be missed.

 

The list of the processed additional characteristics ADDITIONAL contains:

- COUNT - quantity of objects in the list;

- additional characteristics, represented by keywords CODnnn and SIGNn, where n - number of the characteristic in the list. Value of the keyword CODn it is the string containing code and name of the characteristic. The name of the characteristic can be missed. Value of the keyword SIGNn it is the sign, with which one the characteristic's value with number "n" will be used.
