What does it mean when raster to Polygon tool fails?

What does it mean when raster to Polygon tool fails?

Error Message. When converting a raster with many cells to polygons with the Raster To Polygon tool, it fails and displays the following error message: “An error was encountered while executing spatial_RasterToPolygon. Failed to execute (RasterToPolygon_1).”. This also applies to the Raster to Point and Raster to Polyline tools.

How does resample work in raster to Polygon?

The output shapefile is written to disk during processing. This allows the monitoring of the completed amount. Use RESAMPLE the create a coarser or lower resolution version of the raster that can be converted successfully. As the raster is resampled down, fewer features are required to represent it.

How to split a raster into smaller pieces?

As the raster is resampled down, fewer features are required to represent it. At some point, the size of the output shapefile falls below this limit. Use CLIP to split the raster into smaller pieces. These smaller rasters can be converted and processed individually.

Where can I iterate over rasters in Python?

Iterates over rasters in a Workspace or a Raster Catalog. This tool is intended for use in ModelBuilder and not in Python scripting.

Can you create a raster from county level polygons?

I am trying to create a raster data set from county level polygon data for the US. I have successfully created one raster from a dataset, but when attempting another, it does not work. I am wondering if I am missing something.

Is there a problem with ArcGIS Desktop polygon tool?

ArcMap 10 sometimes has issues with background processing on certain machines. If you have background processing enabled, try disabling it (Geoprocessing -> Geoprocessing Options -> Uncheck Enable under Background Processing). Try running your process again and see if that works.

Why is raster unable to clip to desired shape?

I am trying to clip a raster to the shape of a polygon as shown in image 1. But the result that I get is as shown in image 2. Why is this happening?

How to clip raster to desired shape in ArcGIS?

You can also set a clipping extent in the layer properties by right clicking “Layers” in the table of contents pane, select the Data Frame tab, and under clip options expand the drop down menu, select “clip to shape” and select the feature you with to clip by. this method will clip every layer in the table of contents to the specified shape.

What causes an I / O error on a raster?

The most likely cause for a raster I/O error is an I/O error during raster operations. There are a number of possible causes, but a bad block on the disk device is a likely option.

How to check the consistency of a raster list?

You can perform a consistency check by looping through your raster list and storing the important characteristics in a list object, then collapsing to a data.frame. Everything should match except the raster name. Sometimes another error messaged is masked by this message.

How to convert raster to Polygon in ArcGIS Pro?

The Field parameter allows you to choose which attribute field of the input raster dataset will become an attribute in the output feature class. If a field is not specified, the cell values of the input raster (the VALUE field) will become a column with the heading Gridcode in the attribute table of the output feature class.

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.
