This entity stores a raw Block Model. This is a comma-separated ASCII text file, where each row represents a block in the model.


Once you select “Block Model” from the “Add” menu, you will see the following options:



Item Name

A readable name for the new entity

Capture Date

An optional field containing the original capture date

CSV Header

See the paragraph following this table for an explanation of what CSV Header does.

Horizontal Datum

The horizontal datum used in the block model

Vertical Datum

The vertical datum used in the block model

Projection

The projection used by the block model

Horizontal Units

The horizontal unit type used in the block model

Vertical Units

The vertical unit type used in the block model

 

The “CSV Header” field allows defining how each column in the block model will be interpreted. In this field you may enter a line that contains all headers for the block model, separated by commas. For each header, a column definition row will appear in the entity dialog. For instance, if the supplied CSV Header is “XC,YC,ZC,XL,YL,ZL,AU,CU”, the following fields will appear in the dialog:



Each entry in the “Column Definition” can be used to tell the system how the values in that column should be processed. There are two fields to provide in each case. The first field is to select the type that will be used to handle the field. The available types are:


Ignore

Skip this column when processing the block model

Set

The values in this column belong to a set with a limited number of elements that appear many times over in the block model.

Value

The values in this column will be interpreted as numbers. This setting should be used for grades and any other numeric quantity.

Block Centroid X

X coordinate of the block’s centroid

Block Centroid Y

Y coordinate of the block’s centroid

Block Centroid Z

Z coordinate of the block’s centroid

Block Origin X

X coordinate of the block’s origin

Block Origin Y

Y coordinate of the block’s origin

Block Origin Z

Z coordinate of the block’s origin

Block Dimension X

Block’s dimension along the X axis

Block Dimension Y

Block’s dimension along the Y axis

Block Dimension Z

Block’s dimension along the Z axis

 

When providing which columns will provide Block coordinates, you must choose whether to use the Block Centroid or the Block Origin. Attempting to use both in the same block model will be considered an input error.


The second field in the Column Definition allows to select how the Level of Detail (LOD) system will handle the column values when creating a lower frequency representation of the data. The possible options are listed in the following table:


Average

Higher frequency data is averaged to produce lower frequency data

Min

Lower frequency data is set to the minimum value of the local higher frequency data

Max

Lower frequency data is set to the maximum value of the local higher frequency data

Add

Lower frequency data is the sum of the high frequency data. This works well for columns that represent counters.

Multiply

Lower frequency data is the multiplication of the high frequency data.
