Using spatial adjustment

Spatial adjustment allows you to spatially adjust the location of a dataset based on a reference dataset through the following processes: transformation, rubbersheet, and edge snap. In general, these processes are used to improve the planimetric accuracy of features from a feature class. In this recipe, we will learn how to adjust a feature class using an affine transformation. The concepts and recommendations from the Georeferencing raster data recipe of Chapter 3, Working with CRS, are still valid.

Getting ready

In the previous recipe, we added data from the .dxf source datasets to the VeloGIS geodatabase as feature classes. The vectors that came from the RoadCenterLine.dxf dataset have a local cartesian coordinate system. We will consider that the derivate CenterLines feature class has the source coordinate system.

All other dxf datasets are in the right coordinate system, that is, Pulkovo 1942 Adj 58 Stereo 70 (EPSG:3844). We will consider that the derivate Streets...
