(3) Browse image of image data. Enlarge, narrow and roam
the image in the light of infinitely variable map scale.
(4) Query image database. Query and browse the image data
directly, query the map index and query placename.
(5) Image data updates. Its way is same as the way of input
image data basic.
(6) Establishment a placename database. It achieves to
demand the point, line, facial features objects on the
ground,and obtain to position the image data fleetly and
accurately.
4.2 The basic processes of establishing image database
Fig5. The basic processes of establishing image database
4.3 System Example of image database
Figure6 shows the user logged in the database where the image
of Oracle Database examples
Figure7 shows image data table by the prearrange block size
and maps names of being about to enter the database(the table
name of block). Figure 8, 9,10 shows the city examples of
multi-resolution radio images pyramid. The whole image
pyramid is composed of 1:10000, 1:5000 and 1:2000 scale
image data.

From 1:10000 scale image data, we can see a certain region’s
location in the city. From 1 : 5000 scale image data, we can see
a regional overview in the city. From 1 :2000 scale image
data , we can see the specific features of a region in the city. If
we further magnify it , users can view the concerned
information. Figure 11 and Figure 12 are the attributes of space
objectives which is based on placenames in the database. It can
locate image data fleetly and accurately.
