兴趣面
定义并分析兴趣面内的数据
兴趣面 (AOI) 是一种感兴趣区域 (ROI)，用于定义地理空间分析和可视化的关注面。使用 AOI 函数定义方形或圆形 AOI 区域。使用地理编码函数，根据地理编码后的地名获取点、线或多边形形状。
函数
aoiquad | Define quadrangular or rectangular area of interest (自 R2024b 起) |
aoicircle | Define circular area of interest (自 R2024b 起) |
union | Union of shapes in geographic or planar coordinates (自 R2025a 起) |
geocode | Get shape object from geocoded placename (自 R2024b 起) |
placenames | Installed list of placenames for geocode function (自 R2024b 起) |
主题
- Define Areas of Interest
An area of interest defines a focus area for a geospatial visualization and analysis. Define an AOI for imported data, create an AOI from vertices, or get an AOI from a geocoded placename. (自 R2024b 起)
- Clip Vector Data to Area of Interest
Clip point, line, and polygon shapes to an area of interest. (自 R2024b 起)
- Crop Raster Data to Area of Interest
Crop raster data to the bounds of an area of interest. (自 R2024b 起)
- Query Points in Area of Interest
Determine if point shapes are within an area of interest. (自 R2024b 起)
