수평 바람장 분포 표출하기
NOTE:
본 가이드는 흐름도 레이어를 이용하며, 수평면 위에 벡터 장을 표출하는 다른 경우에도 동일하게 적용될 수 있습니다.
NOTE:
In order to visualize wind vectors, you need both u and v components of wind in your dataset.
For the terms & names of UI components, refer to UI Components.
1. Open data file.
Open your data file(s), using Open Data buttons on the Home menu category of Menu Bar.
2. Load the wind vector data and show it on a layer.
In order to visualize the distribution of the variable on a layer, you can either
- click the Add Vector Plane button on Layer menu category, select options, and then click "OK", or
- right-click one of u/v components of wind on the Variables Pane, select 'Add Vector Plane'.
상기 옵션 중 첫번째 옵션을 사용하여 대화상자를 이용하는 경우, 위도 및 경도와 같이 다양한 설정값들을 정확하게 제어할 수 있는 장점이 있습니다.
Rendering Pane will immediately display the vector field of wind, and a new layer will be added to the Layers Pane. By default, wind flow will be shown using wind vectors (arrows) at each grid points.
3. Change the visualization style - wind vector vs. wind barbs vs. streamlines (optional).
On Vector Plane menu category of Menu Bar, you can select one of the following visualization styles:
- Wind vector : show distribution using arrows with variable length & color
- Wind barbs : show distribution using wind barbs
- Streamlines : show distribution using streamlines (optionally with animation)
Each menu button has drop-down submenu, where you can set various options for each visualization style. For example, in streamline style you can choose 'glow' effect and start animation, so that wind flow is visualized using nice and intuitive animation with colored dots that are moving at different velocities.
4. Change the settings for color mapping (optional).
Double click the vertical Color Bar on the right-hand side of Rendering Pane. A popup dialog named 'Setup Colormap and Limit Range' will show up, where you can change various options regarding the color mapping.
5. Explore wind flow at different altitudes (if any).
If your dataset includes wind flow datasets at multiple altitude, you can select a particular height level, or easily change to the next/previous height level.
On Vector Plane menu category of Menu Bar, you will find Vertical Level drop-down control, where you can select height level among all the levels available in your dataset. You can also click Move Up / Move Down button in order to increase / decrease the selected level.
6. Control the size and location of the plane (optional).
You can control the size and location of the plane by using Rendering Pane only. To do this, you do :
- switch from Globe mode to Map mode,
- double-click one of the corners of the plane, to reveal the control handles,
- drag the control handles to change the size and/or height of the plane.
