These datatypes can be expensive to digitize fully, but with the minor effort of registering the images in X, Y, Top and Bottom, the data can be used in GeoScene3D for visualization and modeling.\\ | These datatypes can be expensive to digitize fully, but with the minor effort of registering the images in X, Y, Top and Bottom, the data can be used in GeoScene3D for visualization and modeling.\\ | ||

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.

One way to do this is by opening the image in an image editor. I this example Microsoft Paint is used. Here it’s possible to put X and Y axis on. The axis can help to get the right dimension of the image.\\ | One way to do this is by opening the image in an image editor. I this example Microsoft Paint is used.

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.

An important feature to notice is that is possible to digitize directly on the metadata plane. GeoScene3D will place the digitization points in the right position in the 3D space. | An important feature to notice is that is possible to digitize directly on the metadata plane.
