HOW TO
A raster comprises a matrix of pixels where each pixel contains a value representing information, such as image reflectance, temperature, or height. In ArcGIS Pro, it is useful to convert each pixel of a raster layer to a feature as each feature represents different attributes and spatial information.
In this example, each pixel of the raster layer is converted to a polygon feature for spatial analysis using the Feature To Polygon tool or the Raster to Polygon tool in ArcGIS Pro.
Use the Feature To Polygon tool
In ArcGIS Pro, the outputs from the Raster to Point and the Create Fishnet tools are used as inputs by the Feature To Polygon tool to create the polygon features.
Note: Open the raster layer properties to obtain the Cell Size Width and Cell Size Height values. In the Contents pane, right-click the raster layer, and click Properties. In the Layer Properties window, click the Source tab, and expand the Raster Information group. Specify the Cell Size X value in Cell Size Width, and the Cell Size Y value in Cell Size Height.
Note: The Fishnet Origin Coordinate, Y-Axis Coordinate, and Opposite corner of Fishnet values are automatically specified when the raster layer is selected.
The image below shows each of the pixels converted to polygon features in ArcGIS Pro.
Use the Raster to Polygon tool
Note: Adjacent pixels with the same pixel value are merged into one polygon feature in the output of the Raster to Polygon tool.
The pixels are converted to polygon features and the pixels of the same value are merged into one polygon feature in ArcGIS Pro.
