first question:- a
We have 4 layer, first layer is polygon (zone layer) which contain 3 areas (area1, area2 , area3) , 2nd layer is line (street) which contain subtype (main street , local street) , 3rd layer is land mark and fourth layer is point(outlet)
To get the outlet of area 1 which is inside landmark and away from main street of area 1 about 2 km how can we do it?
Clip only
[Select by attribute then select by dcilocation then select by dcilocation]
Clip street, land mark , outlet by zone layer then select by dcilocation then select by dcilocation
Clip zone by land mark, street, outlet then select by dcilocation then select by dcilocation
Clip street,land mark ,outlet by zone then select by attribute then select by dcilocation then select by dcilocation
None of above
second question
36-If we have layer its name is factory (polygon) and it contain 5 features 3 of them has the following centric coordinate (30.5, 29.5 and 34, 40 and 37, 42) and they have same name
If we need these 3 features to be one row at database of new feature we must do the following
Apend
Merge
Aggregate polygon
Dissolve
None of above
third question
A water network is modeled using geometric network with complex as see in the figure .If you move a junction feature in water network see as you , what happens to features that are connected to the junction feature when we move vertex as shown at drawing?
The features will move with the junction to maintain connectivity
The features will be disconnected from junction feature
The feature will be duplicated to store tow
versions of the network
None of above
