e57fields – print information and statistics on usage of each field name in an E57 format file.


Synopsis

e57fields <e57_file> [start_path]


Description

The e57fields program prints several tables that summarize every occurrence of a field name in an E57 format file. The contents of an E57 file are conceptually organized in a single hierarchy, with three types of branching (or non-terminal) element types (Structure, Vector, and CompressedVector) and five types of non-branching (or terminal) element types (Integer, ScaledInteger, Float, String, and Blob). Associated with some element types are E57 element attributes which are scalar numbers that describe properties of the element or limits on the values that the element may take. Each element in the tree has a field name, which is a string or number that uniquely identifies the element in the branching element (the parent) that contains it. The sub-elements of a branching element are called children. The top-level element in the hierarchy is called the root, and is the only element in the tree with no parent element that contains it. Each element in the tree has a pathname, which is a string that uniquely identifies the element within the tree. The pathname is the concatenation of the field names of the elements that must be traversed to reach the element from the root. The root’s pathname is defined as “/”.


In this program, elements that are children of a CompressedVector (whose values are stored in the binary section of the file) are treated the same as uncompressed elements (whose values are stored in the XML section of the file).


If a start_path is specified, only the E57 element with that pathname and all of its children recursively are summarized.


The meaning of each table is described below.

Examples

e57fields scan0001.e57

e57fields scan0001.e57 /data3D/0/points


Limitations

- Specifying a start_path of an element within a CompressedVector (e.g. “/images2D/0/points/0”) is not supported.


Field usage table

This is probably the most useful table (and the widest). Each line summarizes the occurrences of elements with a given field name.

Column definitions:

count: The number of elements in the file with the given field name. At the bottom of this column is a grand total of the number of elements in the entire file.

field name: The field name that is being summarized. The field name of the root element is defined as “/”. All children of Vectors and CompressedVectors (whose field names are zero based integers) are grouped onto a single line under the field name: “<0,1,2...>”. The field names are arranged alphabetically in the table.

element type: One of the eight E57 element types: Structure, Vector, and CompressedVector, Integer, ScaledInteger, Float, String, and Blob.

measure: Each element type has numeric measure that is statistically summarized on the line. The measure of Structure, Vector, and CompressedVector element types is childCount, the number of direct children that the branching element contains. Integer, ScaledInteger, and Float element types are summarized by the value they contain. The String element type is summarized by the length of the string value it contains. The Blob element type is summarized by the length in bytes of the object it stores.

minimum: The smallest value of the measure in any occurrences of the field name.

mean: The average of the measure for all occurrences of the field name.

maximum: The largest value of the measure in any occurrences of the field name.

minima count: The number of times that the minimum value occurred with the field name.

maxima count: The number of times that the maximum value occurred with the field name.

first occurrence: The path name of the first occurrence of the field name that was encountered as the file was traversed. This provides some context of where the field is used.

Field and distinct type usage table

This table summarizes the number of occurrences of field names and distinct element types. Distinct types are E57 element types including the values of the element attributes. For example, an Integer type with attributes of (min=0,max=255 is distinct from an Integer with attributes of (min=0,max=511).


This table is useful in determining the encoding of CompressedVector fields. Note that when a number of bits is given in the distinct type column, it is the space required for the Bitpack codec. A codec that compresses the values may be much more efficient than the Bitpack codec.

Column definitions:

count: The number of elements in the file with the given field name and distinct type. At the bottom of this column is a grand total of the number of elements in the entire file.

field name: The field name that is being summarized. The field name of the root element is defined as “/”. All children of Vectors and CompressedVectors (whose field names are zero based integers) are grouped onto a single line under the field name: “<0,1,2...>”. The field names are arranged alphabetically in the table.

distinct type: A combination of one of the eight E57 element types (Structure, Vector, and CompressedVector, Integer, ScaledInteger, Float, String, Blob) with the value of the E57 element attributes. The distinct type may be in one of the following forms:

Structure

Vector(heterogeneous) – child elements can be different types

Vector(homogenous) – child elements must be same types recursively.

CompressedVector

Integer(min=MIN,max=MAX) – an integer within interval MIN…MAX

Integer(intN) – an integer whose bounds correspond exactly to a signed N bit integer.

Integer(uintN) – an integer whose bounds correspond exactly to a unsigned N bit integer.

Integer(constant=CONST) – an integer whose min and max bounds are the same.

ScaledInteger(min=MIN,max=MAX, scale=SCALE,offset=OFFSET)

ScaledInteger(intN, scale=SCALE,offset=OFFSET)

ScaledInteger(uintN, scale=SCALE,offset=OFFSET)

ScaledInteger(constant=CONST, scale=SCALE,offset=OFFSET)

Float(precision=single) – a 32 bit IEEE floating point value.

Float(precision=double) – a 64 bit IEEE floating point value.

String

Blob

first occurrence: The path name of the first occurrence of the field name with the distinct type as the file was traversed. This provides some context of where the field is used.


Extremum locations table

This table allows the location of extreme values to be pinpointed. Occurrences of special floating point values are also listed (e.g. NaN and denormals).

value:

first occurrence:

count: The number of elements in the file with the given field name and extreme value.

field name: The field name that is being summarized. The field name of the root element is defined as “/”. All children of Vectors and CompressedVectors (whose field names are zero based integers) are grouped onto a single line under the field name: “<0,1,2...>”. The field names are arranged alphabetically in the table.

element type: One of the eight E57 element types: Structure, Vector, and CompressedVector, Integer, ScaledInteger, Float, String, and Blob.

extremum: What type of extreme is being summarized. May be one of the following options:

min childCount

max childCount

zero childCount

min length

max length

zero length

min value

max value

zero value

qNan value – a quiet NaN (not-a-number) floating point value was encountered

sNan value – a signalling NaN (not-a-number) floating point value was encountered

inf value – a infinite (positive or negative) floating point value was encountered

denormal value – a denormalized (non-standard) floating point value was encountered

-0 value – a negative zero floating point value was encountered

value: The extreme value that occurred with the given field name.

first occurrence: The path name of the first occurrence of the field name and extreme value as the file was traversed.
