Pakistan Journal of Science (Vol. 65 No. 1 March, 2013)<br />

For six of these layers, an attribute table was attached <strong>for</strong><br />

each. In the case of the building layer, first, second and<br />

third storey layers were linked with attribute table.<br />

The kind of data required could be grouped into<br />

two types – the spatial data and the attribute data. The<br />

spatial data include the spatial distribution of the various<br />

Hostels, path ways, trees, Lawns etc within the <strong>hostel</strong>.<br />

The attribute data on the other hand consists of specific<br />

attributes of each object, relevant to the efficient<br />

<strong>management</strong> of the <strong>hostel</strong> students. For instance, the<br />

attributes of each <strong>hostel</strong> building would include number<br />

of rooms, name of student living occupier, program,<br />

session and department of occupier.<br />

Creation of Geodatabase:<br />

Figure: 2 Entity Relation diagram<br />

Figure 2 show the tables of the Geodatabase and their<br />

relationship with one another.<br />

Following seven tables are created in geodatabase.<br />

o Building Food prints (Geometry)<br />

o First floor (Geometry)<br />

o Second floor (Geometry)<br />

o Third floor (Geometry)<br />

o Path ways (Geometry)<br />

o<br />

o<br />

Trees (Geometry)<br />

Student table<br />

First six tables are geometry in<strong>for</strong>mation as well<br />

as tabular in<strong>for</strong>mation. After creation the tables all the<br />

layers are digitized. ArcMap 10 is used to digitize the all<br />

layers. Adding the satellite and scanned image of<br />

university first six layers were digitized and then attribute<br />

regarding the features were interred in the layers. Student<br />

table is non spatial table unlike other table ,it holds the<br />

in<strong>for</strong>mation of the student i.e. name , father name, class,<br />

session, re<strong>gis</strong>tration ID, department ,subject and so on.<br />

First, second and third spatial layers are showing<br />

the first, second, third storey respectively of the building<br />

of <strong>hostel</strong>. Each storey has a space id which is unique in<br />

each floor. This space id is used to relate with the student<br />

table, in this way all floors of all <strong>hostel</strong> included in this<br />

application are linked with the student table.<br />
