This lecture includes these contents: ERS 120 Principles of GIS, working with tables, opening data and change theme names, preparing spatial join,. Invite you to result this lecture. | Practice 4: Working with tables ArcView Steps 18 Step 1 Opening data and change theme names . 18 Step 2 Preparing spatial join 18 Step 3 Spatial Join . 19 Step 4 Buffering . 21 Step 5 Spatial relationship (Select By Theme) 23 This practice extends your knowledge ofhow GIS is used to find new information based on existing data. Perhaps the defining feature of a geographical information system is the ability to analyse data in a spatial context. Other software can handle attribute or even geographical data, however a GIS can take these data and increase your knowledge about the place. This practice covers a few ofthe kinds of analysis that GIS software can do. In this practice, you will be able to: • Relate (join) non-spatial database table to a geographical-based table (spatial join) • Create buffers for geographic features (buffering) • Discover the ability to select the features of one or more themes using the features of another theme (spatial relationship) Firstly, you will need to start ArcView, start a new project, add a view and set the working directory (to c: \temp or c:\) as practiced last week. Secondly, you need to open a View using the view icon in the project window in ArcView. Thirdly, you need to add some themes, , , and from the directory, c:\arcv32\arcview\esridata\europe\. This is the same process what you had done in the first practice session. These themes will now be added to
