Cell values represented by NoData are not calculated in the raster attribute table.Outside a geodatabase, for a file-based raster dataset, the raster attribute table is saved in the same folder or at the same directory level as the raster, using the same name as the raster and appending ...
Adds a raster attribute table to a raster dataset or updates and existing one. This is used primarily with discrete data. Usage To delete an existing table and create a new one, check theOverwriteparameter. A new raster attribute table will be created, and the existing one will be deleted...

The maximum number of unique values within a raster attribute table The default pyramid building option allows you to choose whether to build pyramids for raster datasets that do not have pyramids before they are displayed. There are three options for this setting: to always build pyrami...
NoData —NoData 値を無視します。 Spatial Reference —空間参照系を無視します。 Pixel Value —ピクセル値を無視します。 Colormap —カラー マップが存在する場合は無視します。 Raster Attribute Table —属性テーブルが存在する場合は無視します。
I would vote for using standard python data structures. There are two main options I see: List of dicts, one per row. If I understand your code correctly, this is what you've already implemented. The disadvantage to this is there is no way to quickly lookup the attribute table for a ...

This sample shows how to use the attribute table of an ImageryLayer to mask pixels from display. The pixelFilter property of the layer allows the developer to add color to each pixel using RGB values and exclude unwanted pixels.This layer contains land cover data. Each pixel value represents ...
打开attribute table,找到缺失数据的行,按住CRTL进行多选。可以手动选,也可以用红色框中的选择/过滤功能。 启动编辑模式后,删除选定数据缺失的行,保存编辑。 将气温的单位从0.1℃,变成℃。 新建一列:设置域名、描述、数据类型。 编辑公式。 Interpolate point features to raster ...
A feature class or table can have a raster attribute field to store any raster related to the feature. You can edit raster values in the raster field using the Editor tool. If you have many raster datasets to add to the raster field, you need to write a custom application to simplify ...
