2021年9月7日 · If you can get the extent of the raster, you can create a polygon then add that to a new featureclass. Extent—ArcGIS Pro | Documentation. If you prefer a simple raster representing the extent, then. Create Constant Raster (Spatial Analyst)—ArcGIS Pro | Documentation. using a value of 1 and the cell size and extent of your current raster.

You can do it easily with "arcpy" module in Python: The important thing is that you have to read the spatial georeference system of the input raster, and create a polygon feature with the same spatial georeference system. You read the corners of the raster and add points to a polygon shape. Then you add the shape to your feature class.

2016年5月16日 · I'm using Polygon to Raster tool to create a raster (10x10). The problem is that some cells of the output raster is not assigned any value. My understanding is that the tool always uses the cell center to decide the value of a raster pixel. Attached is the result when I overlay both the output raster and Input polygon on ArcMap.

2017年2月28日 · (In the backround green polygon, in the front the raster after using the polygon to raster.) I have some polygons and I try to create special management zones for these. So firstly I use polygon to raster option to create one raster layer, than Boolean layers and some reclassify, after all I use the raster to polygon options.

2015年5月7日 · The raster data model is based on a single value per cell for most operations. If you want to preserve attributes on the raster side, these suggestions are right on - specify the ObjectID field as a "Value field" for the Polygon To Raster tool, and then copy the polygon attributes over to the raster attribute table using the Join Field tool.

2024年3月13日 · TLDR: Enable Raster to Polygon Tool to use non-Integer-based rasters. Currently to make a polygon from a raster, the raster needs to be an integer. This means that I have to multiple the raster by 1000 (or a million) with an INT output, convert to polygon, then divide by 1000 (or a million) to get back to what I want.

2016年10月6日 · I have a raster file (elevation) and a shape file (neighborhood polygons). I would like to sample the raster for each polygon and assign the average raster value to its' respective polygon. Ideally I would add a new column with the average elevation for …

2016年9月27日 · I would like to calculate the proportion of each of the land cover types in each polygon. For example: I would like to know what percentage of each polygon is natural, semi transformed and transformed. I would like this information to be contained in the attribute table of the polygon feature class. I am using ArcView License, ArcMap 10.0.

2020年3月31日 · I want to convert the following Polygons (see Image) into Raster using QGIS and used the Tools 'rasterize' from QGIS and SAGA as well as GRASS v.to.raster. They all give me the same result: I want the raster to be only under the individual Polygons. The problem is that I used the Polygon Layer as Output extent of the tool.
