In the last chapter we learned how to utilize the representation model of GIS to create spatial visualizations and digital maps. Our final map is very nice, although it has some flaws remaining. In this chapter, we will fix some of the issues (for example, dangling lines, features sticking out of the study area) and learn how to export our map to two kinds of graphics--SVG (Scalable Vector Graphics) and image formats (for example, PNG). Then, we will go on to learn about different spatial data exchange formats. We will discuss their main properties and limitations to be able to choose the best for our project.
In this chapter we will cover the following topics:
- Clipping vector and raster data
- Exporting as graphics
- Spatial data exchange formats
