____ 24. Start ArcMap with a new, blank map. Add School_Court_A. Change the lines in School_Court_A to Mars Red, with a width of 2.

When you transform the court into real-world coordinates, the feature class dimensions will change and it will be rotated to fit the spot. All that is important here is that the right lines are connected and that the image is not distorted.

____ 26. Add the image file six.tif from [___]IGIS-Arc\Image_Data. (Do not build pyramids if asked. Ignore the warning about the unknown spatial reference.) Zoom to the layer. In the southwest corner of the image is a school with a running track. Zoom to the school, including the track. Bookmark this image, calling it School. In the south-central part of this image, you should be able to discern most of a large parking lot.

It has been decided to make a full-size Foozit Court in the parking lot of the school. A surveyor was hired to specify the corners of the ...
