NETWORK ANALYSIS

AIM: To create and analyze the given water pipeline system

MATERIAL USED

ArcMap 10.2

PROCEDURE

1.Open ArcMap 10.2 → click blank → ok

2.Add the image

3.To create a personal geodatabase

Arc Catalogue→ create new folder → right click → new →

personal geodatabase (ref to geodatabase practical)

4.Right click →new → feature dataset → (pipeline) → next →

geographical coordinate system → World → WGS1984 → next → next → finish

5.Create feature class for line and point features in the same manner

Pipeline → right click → new → feature class → class name → next →

enter field name and type → ( e.g: name – text, subtype- short integer ) → finish

(pipeline →right click → new → feature class → class name → next →

enter field name and type (e.g: name –  text, subtype – shortinteger) → finish

6.Layer → right click → properties → coordinate system → globe icon →

clear → apply → ok (only for this)

7. Line features class → right click → property → subtype →

set subtype field as subtype → clear the code number and subtype name → apply → ok

*Repeat the step 7  for other point features

8.Remove the feature from the table of content and drag the feature from the catalogue to

the table of content

9.Change the colors of the subtype just like the color gave in the map.

10.To digitize the map: Click line distribution feature→Select straight segment

*Mark the line for distribution features in the same method for the subtypes

11.Mark every line and point features in the same methods for the subtypes

12.After digitization

Dataset (pipeline) → right click → new → geometric network → next →tick features

Line – role set as complex edge

Point – source set as yes

Next → next → finish

13.Editor → star editor

14.Layer → point → click right → attribute table →set intake as source

15.On utility table by right click on the task bar

Flow → display arrow

16.To edit the error

Locate the error by simply zoom at the error location → Select features tool →

click at the error features → then open attribute table → delete the feature

17.For Analysis, Select flag from the utility toolbox and put the flag at any point then

set the analysis type → click the solve tool

18.To remove the flag or analysis

Analysis → clear flag or clear result

Different type of analysis

RESULT
