ArcGIS generates the steps to generate contour polygons from point layers and reduce the aliasing of the Rasters

Original: ArcGIS generates steps to generate contours based on point layers and reduce grid aliasing

First, open ArcMap and load the corresponding point layer and boundary polygon layer

Second, Arctoolbox--spatial analyst Tool----difference analysis-- kriging (according to different circumstances to choose different algorithms, this time the processing is actually using spline method, more smooth than other algorithms, similar operation steps, parameter settings can set the test effect) , make the following settings in turn

Click Environment for detailed settings

The next step of setting "cell size" is the key to resolving aliasing, and masking is the main function of setting the plot range

Determined after success

Generate Raster Data: Right-created layer--export data

Third, generate contour lines

Arctoolbox--spatial Analyst Tools-Surface analysis-Contour lines

Label the appropriate fields
