2DGridCreator

点或多边形特征网格。

Note that the same number of features will be output whether points or polygons are requested. Therefore, the bounds of the output will be smaller for a point grid than for a polygon grid. For instance, the width of the bounding box of a polygon grid will be (Number of Columns) * (Column Width), whereas the width of the bounding box of a point grid will be (Number of Columns– 1) * (Column Width).

The starting corner of the grid. The possible values are:

• Lower Left
• Upper Left
• 右下
• Upper Right

TheStarting X Coordinate和Starting Y Coordinate参数为整体指定网格的起始角的原点。

TheStarting X Coordinate和Starting Y Coordinate参数为整体指定网格的起始角的原点。

TheNumber of Columnsparameter specifies the number of features (points or polygons) each row of the grid will have. This must be at least one.

The行数parameter specifies the number of features (points or polygons) each column of the grid will have. This must be at least one.

TheColumn Width和Row Heightparameters specify in ground units the distance between output points in the grid or the width and height of the output polygons.

TheColumn Width和Row Heightparameters specify in ground units the distance between output points in the grid or the width and height of the output polygons.

Choose point or polygon features.

Polygonfeatures will be rectangular boxes with the specified column width and row height.

选择Points (Corners)will output a point for each of the corners of the cells in the grid.Points (Centers)will give a point for the middle of each cell.

Note that there will be an additional row and column output forPoints (Corners)超过的数字多边形或者Points (Centers)will generate.

IfRow Attributeis specified, an attribute will be added to each output tile that identifies the vertical position of that tile in the input raster. This index is zero-based, beginning at the specifiedStarting Corner.

IfColumn Attribute指定了，将添加属性，每个输出区块识别输入栅格中该图块的水平位置。此索引基于零，从指定开始Starting Corner.

此参数允许您在创建的功能上设置坐标系。从下拉列表中选择坐标系，或单击“浏览”按钮以从坐标系库中进行选择。如果将此参数留空，则不会设置此变压器创建的功能的坐标系。

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

设置值 - 无论是否直接在参数中输入或使用其中一个编辑器和包含字符串的表达式都是构造的，都会评估这些函数的字符串和表达式。因此，这些函数的名称（以@ <function_name.>) should not be used as literal string values.
