This contains the average temperature value extracted over the polygon for each feature. There are some null values because those counties (belonging to Alaska, Hawaii and Puerto Rico) are outside of the raster layer’s extent.If you want to give feedback or share your experience with this ...

1.Input Layer:The input vector file to be converted. The tool supports multiple vector formats. 就是你希望转化的vector layer 2.Field to use for a burn-in value[option]: The field name from the polygon to be burned into raster 你选择转化的矢量层 为啥是option? 有时候一个矢量层有多个attrib...
“Clip trajectories by extent”still exists but, additionally, we can now also“Clip trajectories by polygon layer” There are two new event extraction algorithms to“Extract OD points”and“Extract OD points”, as well as the related“Split trajectories at stops”. Additionally, we can also“Sp...

Automatic digitizing, at its core, is the conversion of raster-based information, such as satellite images or scanned maps, into vectorized representations such as points, lines, and polygons. This conversion process is critical in a variety of industries, including cartography, urban planning, and...
