1

Map Panel

The Map Panel is the core interface of the data editor. It combines map browsing with geometry editing. Its top and left toolbars create an efficient user experience.

2

Data Table Panel

The Data Table Panel is the core management interface. It provides end-to-end data processing, from upload and editing to export. It supports various geographic data formats for import and standardized output. The structured design helps you manage and work with geographic data efficiently.

3

GeoAtlas Copilot

GeoAtlas Copilot is a built-in smart tool. It uses natural language to help you complete map tasks quickly. These tasks include route planning, location queries, data simulation, and analysis. This greatly improves your efficiency.

Function

Description

Select map area

The left side of the toolbar has a smart area locator. You can select from a drop-down list or search by keyword for Chinese administrative regions, down to the county level. This allows for precise and fast map positioning.

Undo and redo

Click the icon on the right to undo the current operation. This returns you to the previous state. Click the icon on the right to redo the last step.

Delete

Delete single or multiple data items. Select data by clicking or drawing a box, then click the icon. The icon is disabled if no data is selected.

Copy

Select data by clicking or drawing a box, then click the icon. A copy of the data is created at an offset from the original. The icon is disabled if no data is selected.

Select data

Select data by clicking or drawing a selection box. Selected data is also highlighted in the Data Table Panel below. Press the Esc key to deselect all data.

• Single selection: Click a feature to select it. Click multiple features to select them. Click a selected feature again to deselect it.

• Box selection: Draw a box on the map to select multiple features within the area. Selection shapes include Rectangle, Circle, and Polygon.

Draw feature

Draw Point, Line, Rectangle, Circle, and Polygon features. Click an icon to start drawing. Press the Esc key to cancel. After you finish drawing, the feature's data appears in the Data Table Panel below.

Feature editing tools

The feature editing tools include Translate, Rotate and Scale, and Edit Vertices. Click an icon to enter its editing mode. These tools are disabled if there is no data on the map.

Feature spatial relationships

These tools manage spatial relationships between features. They include Merge Geometry, Intersect Geometry, and Difference Geometry. These tools are disabled if you select fewer than two features.

• Merge Geometry: Select two or more features of the same type, then click the icon to merge them. The features become a single entity. If they intersect, they form a new polygon.

• Intersect Geometry: Select two or more polygon features, then click the icon to calculate their intersection. Enable Skip points and lines to ignore any selected point and line data.

• Difference Geometry: Select two or more polygon features, then click the icon to calculate their difference. Enable Skip points and lines to ignore any selected point and line data.

Feature processing toolset

This toolset includes Discretize Feature, Clip Feature, Simplify Feature, Generate Random Points in Polygon, and Generate Random Points Along Line. The tools are disabled if no data is selected.

• Discretize Feature: The discretization feature breaks down composite geometry types (MultiPolygon, MultiLineString, or MultiPoint) into individual features (Polygon, LineString, or Point). This is the reverse of merging geometries. Use it when you need to process individual parts of a composite feature separately. The following example shows the process.

  Before discretization:

  After discretization:

• Clip Feature: Select one or more features and click the icon. In the dialog box, select Click to draw clipping path and draw a path to clip the features. When you finish drawing, the path data appears in the input box. Click Execute to finish. The original features are split into new, separate, editable features along the path.

  Note

  A clipping path is considered invalid if it is completely inside a single feature.

• Simplify Feature: This reduces the number of vertices and details in polygon data while keeping key features. Select a feature and click the icon to open a dialog box. Configure Simplification Tolerance and Simplification Quality, then click Execute.

  • Simplification tolerance: Controls the level of detail. A larger tolerance results in a greater simplification and a rougher shape.

  • Simplification quality: Normal simplification prioritizes speed over geometric precision. High-quality simplification preserves shape features for higher precision and better visual results.

• Generate Random Points in Polygon: Use this to distribute point data randomly or uniformly within one or more polygons. Select a polygon feature, click the icon, configure the settings in the dialog box, and then click Execute.

  • Maximum quantity: The maximum number of points to generate within a single polygon.

  • Distribution rule: Supports three rules: random distribution, clustered distribution, and uniform distribution.

    • Random distribution: Points are distributed completely at random within the area.

    • Clustered distribution: Point features are distributed according to a clustering pattern rather than completely at random. A value field is generated in the data table to simulate spatial clustering.

    • Uniform distribution: Point features are generated randomly within the area, while attempting to maintain an even distance from each other and avoid clustering.

  • Create temporary table: If enabled, a new temporary table is created to store the generated data.

• Generate Random Points Along Line: Use this to distribute point features along a line feature according to specific rules or density. This is often used to simulate events or for spatial sampling analysis. Select a line feature, click the icon, configure the settings in the dialog box, and then click Execute.

  • Maximum quantity: The maximum number of points to generate on a single line.

  • Buffer radius: Sets a range on both sides of the line within which points are generated. This controls the spatial spread and coverage of the point distribution.

  • Create temporary table: If enabled, a new temporary table is created to store the generated data.
