Create Fishnet

Feature Description

The Create Fishnet function quickly generates a regular rectangular grid region dataset by specifying spatial range and grid parameters, and can automatically complete marking of fishing nets, used for tracking and managing work progress in data capture and editing processes.

Application Scenarios

  • During DLG data capture, by creating a regular fishing net, the work area is divided into grids, achieving systematic decomposition of work tasks.
  • By marking the grid status, production progress is recorded in real-time, effectively preventing omissions and ensuring the completeness and orderliness of data updates.
  • As an auxiliary management tool for data capture, it collaborates with functions such as feature collection, progress tracking, and quality control to build a systematic work management system.

Version Information

Starting from SuperMap iDesktopX 2026 version, the Create Fishnet function is provided.

Function Entry

  • Edit Data tab -> Fishnet group -> Create Fishnet button
  • Toolbox-> Data Management->Sampling group-> Create Fishnet tool

Parameter Description

Parameter Name Parameter Interpretation Parameter Type
bounds settings

Provides two setting methods: Current Map Window Extent and Specify Dataset Range:

  • Current map extent (default): Uses the current map display range as the fishing net range.
  • Specify Dataset Range: After selecting this item, activate the "range data source/dataset" control, and you can choose existing datasets as range references.

Cell Width Grid cell width, in meters Double
Cell Height Grid cell height, in meters Double
Column Count Number of grid columns Integer
Row Count Number of grid rows Integer
Create Mark

Sets whether to create fishing net marks:

  • If checked - generates annotations based on the fishing net and automatically performs the following operations:
    • Creates a text field named mark for the dataset, and assigns an initial value of 0 to all objects.
    • Generates a unique value thematic map: Created based on the mark field, with sub-item 0 having a red border and no fill, sub-item 1 having a red border and yellow fill, and the default item having a red border and no fill.
    • Generates a label thematic map: Generates marks at the center points of the fishing net based on the mark field.
  • If not checked - only generates the fishing net region dataset and does not generate marking of fishing nets.

Output Result

Parameter Name Parameter Interpretation Parameter Type
result dataset
  • The generated fishing net region dataset. The coordinate system rules for the result dataset are as follows:
    • If Current Map Extent is specified, the coordinate system of the result dataset is the same as the map coordinate system.
    • If Specify Dataset Range is specified, the coordinate system of the result dataset is the same as the specified dataset's coordinate system.
  • If Create Mark is checked, after the tool execution is completed, the two generated thematic layers are added to the top of the layer manager, the "Fishing Net Mark" dialog box pops up, and parameters are automatically completed.
