Learn to populate a geodatabase with data including georeferencing images, digitizing, and establishing relationship rules. Complete lab 3 with UML diagram and map creation. Due next Wednesday.
E N D
Purpose • Populating a geodatabase (fill it with data)
What to do • Georeferencing an image • An image without coordinate information is placed at (0,0) as default
What to do • Georeferencing an image 1. Define the coordinate system 2. Move the image to its correct location.
What to do • Digitizing • Use “Editor” toolbar
Notes • Question 6– validation • You will get a “successful” result if you did not define the rules in the relationship class (Software issue). • Solution A: Guess what will happen if you have defined the relation rules, and explain the reason. • Solution B: Define subtypes (manually) and then establish relation rules.
Notes • About the Map (9 points) • 2 points – map elements (scale bar, north arrow…) • 4 points -- map content. Make sure that different symbols are used for the various feature types, and that they are in fact the correct feature types. (e.g. Main pipes can only run down the middle of streets) • 3 points – data source and coordinate information.
Assignment • Complete lab 3. • The question sheet, with typed answers • One UML diagram of the geodatabase • One map of the neighborhood pipe network • Due date: Next Wednesday (Feb. 15th)
