我希望的到100m* 100m分辨率的raster data, 所以我选择georeferenced units 然后Width/Horizontal resolution和Height/Vertical resolution 均填的是100 5.Output extent 输出的范围 这里你可以根据另一个vector data进行裁剪,比如你可以设置行政边界vector为输出的范围,那么你会得到根据行政边界转化的raster data 6.Assign...

Georeferencing allows us to bring static geographic information into a dynamic mapping environment. A georeferenced map can be used as a new background or basemap in a GIS project or interactive web map. Georeferenced maps can also be used to create new vector data by tracing (aka digitizing) ...

Layout contains 2 rasters: one generated by TIN interpolation and other generated with hillshade. Task is to overlap them and export layout to pdf. Layout also contains some vector layers such as contours. Acoording to this paragraph in QGIS user manual (Fig. 1) those two layers should be...
