| To be sure that the image fits in the topography it is important to get the right dimension of the image. The dimension of the image is from the top of the image (top of paper) to the bottom of the image. This is important to note, it’s the top/bottom of the whole image, including headers and margins that must be registered.\\ | To be sure that the image fits in the topography it is important to get the right dimension of the image.

| The red bar in the left side of the figure below illustrates the dimension of that image. The log goes from 0 to 5 meters. 1 meter on the log is 60 units in Paint. The whole image is 890 units long. That gives 14.8 meter equal to the size of the image in meters. The top elevation to put in the database is therefore equal to the elevation of the topography. You might have to set the top elevation a little higher to get the beginning of the log to be at the same level as the topography. The bottom elevation is the topography elevation minus 14.8 meters. | The red bar in the left side of the figure below illustrates the dimension of that image.
