How to convert raster to polygon using ArcGIS for desktop?
Convert raster to polygon based on cell value ranges using ArcGIS for Desktop? I have a floating point-valued raster which I need to convert to polygon as follows Put the cells with VALUE < 0.5 into (a small/the smallest number of) polygons and so on.. I looked at the Raster to Polygon tool, but there is no place to specify range values.
How do you label a polygon in raster?
1) Use the Raster to Point tool to convert each pixel to a point (found in Conversion Tools > From Raster). These points are later used to label polygons. 2) Navigate to ArcToolbox > Data Management Tools > Feature Class > Create Fishnet. The values entered into this tool are taken from the properties of the raster.
How to do shape raster to Polygon in fishnet?
Run the Feature to Polygon tool on the fishnet output from step 2, with the Raster to Points output specified in the Label Features field. This gives the final polygon which has a field named GRID_CODE with the cell values of the raster. Thanks for contributing an answer to Stack Overflow!
Where to find raster to points in ArcToolbox?
To access the properties of the raster, right-click the raster in the Table Of Contents in ArcMap > Properties > Source tab. 3) Navigate to ArcToolbox > Data Management Tools > Features > Feature To Polygon. Run the Feature to Polygon tool on the fishnet output from step 2, with the Raster to Points output specified in the Label Features field.
What do you need to know about raster in Excel?
The raster must be integer type. The output feature class that will contain the converted polygons. Determines if the output polygons will be smoothed into simpler shapes or conform to the input raster’s cell edges. SIMPLIFY —The polygons will be smoothed into simpler shapes.
How to convert a raster to a vector?
I would use either the Con or Reclassify tools to create a new raster with the value range that you are interested in and then perform the raster-to-vector conversion on this newly created raster. Two steps and you’re done! Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
What happens when the raster does not match the extent?
If Extent is specified in the environment setting and the lower-left corner of the output extent does not match any cell corner of the input raster, during processing, a shift of the cell alignment of the input raster will occur to match the specified extent.
