order [in] order is a parameter of type long interpolatedRaster [out, retval]interpolatedRaster is a parameter of type IGeoDataset
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Remarks
| geoData | an input point featureclass containing the points with z values to be interpolated onto a surface Raster |
| trendType | an esriGeoAnalysisTrendEnum specifying the type of regression to be performed
esriGeoAnalysisLinearTrend polynomial regression is performed to fit a least-squares surface to the set of input points It is applicable for continuous types of data. esriGeoAnalysisLogisticTrend logistic trend surface analysis is performed It generates a continuous probability surface for binary, or dichotomous, types of data. |
| order | order of the polynomial
It must be an integer value 1 through 12. A value of 1 will fit a flat plane to the points, and a higher value will fit a more complex surface. A commonly used value is 1. |
