Chapter 6. Advanced Data Creation and Editing
This chapter will provide you with more advanced ways to create vector and raster data. There is a great deal of spatial data held in tabular format. Readers will learn how to map coordinate and address-based data. Other common sources of geospatial data are historic aerial photographs and maps in hard copy. Readers will learn how to georeference scanned imagery and transform it into a target coordinate reference system. The final portion of the chapter will cover testing topological relationships in vector data and correcting any errors via topological editing.
The topics that you will cover in this chapter are as follows:
- Creating points from coordinate data
- Geocoding address-based data
- Georeferencing imagery
- Checking the topology of vector data
- Repairing topological geometry errors via topological editing
