Create Fishnet

Creates a fishnet of rectangular cells. The output can be polyline or polygon features.

1.    Output Feature Class

The output feature class containing the fishnet of rectangular cells.

2.    Template Extent (optional)

Specify the extent of the fishnet. The extent can be entered by specifying the coordinates or using a template dataset.

1. Left—XMin value
2. Right—XMax value
3. Bottom—YMin value
4. Top—YMax value

3.    Fishnet Origin Coordinate

The starting pivot point of the fishnet.

4.    Y-Axis Coordinate

The Y-axis coordinate is used to orient the fishnet. The fishnet is rotated by the same angle as defined by the line connecting the origin and the y-axis coordinate.

5.    Cell Size Width

Determines the width of each cell. If you want the width to be automatically calculated using the value in the Number of Rows parameter, leave this parameter empty or set the value to zero—the width will be calculated when the tool is run.

6.    Cell Size Height

Determines the height of each cell. If you want the height to be automatically calculated using the value in the Number of Columns parameter, leave this parameter empty or set the value to zero—the height will be calculated when the tool is run.

7.    Number of Rows

Determines the number of rows the fishnet will have. If you want the number of rows to be automatically calculated using the value in the Cell Size Width parameter, leave this parameter empty or set the value to zero—the number of rows will be calculated when the tool is run.Number of Columns Determines the number of columns the fishnet will have. If you want the number of columns to be automatically calculated using the value in the Cell Size Height parameter, leave this parameter empty or set the value to zero—the number of columns will be calculated when the tool is run.

8.    Number of Columns

Determines the number of columns the fishnet will have. If you want the number of columns to be automatically calculated using the value in the Cell Size Height parameter, leave this parameter empty or set the value to zero—the number of columns will be calculated when the tool is run.

9.    Opposite corner of Fishnet (optional)

The opposite corner of the fishnet set by X-Coordinate and Y-Coordinate values. The values for opposite corner are automatically set if a template extent is used. This parameter becomes disabled if the origin, Y-axis, cell size, and number of rows and columns are set.

10. Create Label Points (optional)

Specify whether or not a point feature class will be created containing label points at the center of each fishnet cell.

1. Checked—A new feature class is created with label points. This is the default.
2. Unchecked—The label points feature class is not created.

11. Geometry Type (optional)

Determines if the output fishnet cells will be polyline or polygon features.

1. POLYLINE—Output is a polyline feature class. Each cell is defined by four line features.
2. POLYGON—Output is a polygon feature class. Each cell is defined by one polygon feature.

Create Random Points

Create Random Points

Path to access the tool

:

Create Random Points Tool, Sampling Toolset, Data Management Tools Toolbox

 

Create Random Points

Creates a specified number of random point features. Random points can be generated in an extent window, inside polygon features, on point features, or along line features.

1.    Output Location

The location or workspace in which the random points feature class will be created. This location or workspace must already exist.

2.    Output Point Feature Class

The name of the random points feature class to be created.

3.    Constraining Feature Class (optional)

Random points will be generated inside or along the features in this feature class. The constraining feature class can be point, multipoint, line, or polygon. Points will be randomly placed inside polygon features, along line features, or at point feature locations. Each feature in this feature class will have the specified number of points generated inside it (for example, if you specify 100 points, and the constraining feature class has 5 features, 100 random points will be generated in each feature, totaling 500 points).

4.    Constraining Extent (optional)

Random points will be generated inside the extent. The constraining extent will only be used if no constraining feature class is specified.

5.    Number of Points [value or field] (optional)

The number of points to be randomly generated.

The number of points can be specified as a long integer number or as a field from the constraining features containing numeric values for how many random points to place within each feature. The field option is only valid for polygon or line constraining features. If the number of points is supplied as a long integer number, each feature in the constraining feature class will have that number of random points generated inside or along it.

6.    Minimum Allowed Distance [value or field] (optional)

The shortest distance allowed between any two randomly placed points. If a value of 1 Meter is specified, all random points will be farther than 1 meter away from the closest point.

7.    Create Multipoint Output (optional)

Determines if the output feature class will be a multipart or single-part feature.

1. Unchecked—The output will be geometry type point (each point is a separate feature). This is the default.
2. Checked—The output will be geometry type multipoint (all points are a single feature).

8.    Maximum Number of Points per Multipoint (optional)

If Create Multipoint Output is checked, specify the number of random points to be placed in each multipoint geometry.

Generate Points Along Lines

How to Generate Points Along Lines Tool in Arc Toolbox ArcMap ArcGIS??

Generate Points Along Lines

Path to access the tool

:

Generate Points Along Lines Tool, Sampling Toolset, Data Management Tools Toolbox

 

Generate Points Along Lines

Creates point features along lines or polygons at fixed intervals or by percentage.

1.    Input Features

The line or polygon features to be converted into points.

2.    Output Feature Class

The point feature class that will be created from the input features.

3.    Point Placement

The method to use to create points.

1. PERCENTAGE—The tool will use the Percentage parameter to place points along the features by percentage.
2. DISTANCE—The tool will use the Distance parameter to place points at fixed distances along the features. This is the default.

4.    Distance (optional)

The interval from the beginning of the feature at which points will be placed.

5.    Percentage (optional)

The percentage from the beginning of the feature at which points will be placed. For example, if a percentage of 40 is used, points will be placed at 40 percent and 80 percent of the feature's distance.

6.    Include End Points (optional)

Specifies whether additional points are placed at the start point and end point of the feature.

1. Checked—Additional points will be added at the start point and end point of the feature.
2. Unchecked—No additional points will be added at the start point and end point of the feature. This is the default.

Generate Tessellation

How to Generate Tessellation Tool in Arc Toolbox ArcMap ArcGIS??

Generate Tessellation

Path to access the tool

:

Generate Tessellation Tool, Sampling Toolset, Data Management Tools Toolbox

 

Generate Tessellation

Generates a polygon feature class of a tessellated grid of regular polygons which will entirely cover a given extent. The tessellation can be of triangles, squares, or hexagons.

1.    Output Feature Class

The path and name of the output dataset containing the tessellated grid.

2.    Extent

The extent that the tessellation will cover. This can be the currently visible area, the extent of a dataset, or manually entered values.

3.    Shape Type (optional)

The type of shape to tessellate.

1. HEXAGON—A regular six-sided polygon with equal side lengths.
2. SQUARE —A regular four-sided polygon with equal side lengths.
3. TRIANGLE—A regular three-sided polygon. Currently only supports equilateral triangles.

4.    Size (optional)

The size of each individual shape that makes up the tessellation.

5.    Spatial Reference (optional)

The spatial reference to which the output dataset should be projected. If a spatial reference is not provided, the output will be projected to the spatial reference of the input extent. If neither has a spatial reference, the output is projected in GCS_WGS_1984.
