Importing GIS data

00:03

location data can be imported into info drainage

00:06

from several different sources and in different orders.

00:09

This allows you to customize the process of building a drainage map,

00:14

for example,

00:15

Geographic information system or G. I. S. Data in the shape file

00:20

hX format

00:21

is commonly imported into drainage models

00:25

to import G. I. S data

00:27

from the tree view.

00:28

Right click the connections node and select import from G I. S.

00:34

The Gis import wizard opens

00:37

in the first page. You must specify the G. I. S.

00:40

File format and then browse for the file you want to import

00:45

for this exercise.

00:46

Set the source as shape file and then click select

00:50

for this exercise in the data folder, select the file pipes underscore only line

00:57

and then click open

00:60

with the file path. Now showing on the select source page, click next

01:05

in the select tables, page is a preview of what the imported data will look like

01:10

and you can select the tables you want to be imported from the G. I. S. File.

01:15

In this case there is only one table

01:17

Also you need to set the units, the spatial data is stored in.

01:22

Optionally you can set a key value to color code the added pipes

01:27

for now. Just make sure meters is selected in the units. Drop down

01:32

and then click next

01:35

on the select template page.

01:36

You must select a template on which to base the imported connections

01:40

and it lists the various connection types

01:44

for this exercise.

01:45

Since none of the other objects apply,

01:47

make sure the box next to pipe is checked and then click next,

01:53

another.

01:53

Select template page appears prompting you to select a template on

01:57

which to base any interim junctions that need to be created,

02:01

make sure manhole is checked

02:03

and again click next.

02:06

This opens the map properties page again where you pair up the

02:09

headers on the left with the available imported data on the right.

02:14

In this case you do not need to map anything

02:16

because this imported data does not inform the pipes attributes

02:21

only their positions in relation to the manholes already shown in the plan view,

02:26

click import and view the import summary.

02:29

Then click OK.

02:32

The pipes are imported into the plan view showing

02:35

their connections to the manholes and flow directions.

02:38

Double click one of the pipes to see a list of the connections and their details,

02:44

click cancel to exit.

02:46

Now repeat the importing process to add inflows,

02:51

Right click on inflows in the tree view and select import from G I S

02:57

in the following menus, select shape file,

02:60

then sub catchment underscore boundaries polygon

03:04

and make sure the box next to catchment area is checked.

03:08

Click import

03:11

in the plan view.

03:12

You can now see the sub catchment boundaries represented by green polygons.

03:17

Zoom in to see how the inflows connect to the manholes

03:22

info,

03:22

drainage has made some sensible assumptions based on the data already provided,

03:26

but you could set specific connections between inflows

03:29

and manholes by importing additional source data.

03:33

You can also adjust an individual inflow connection by

03:36

right clicking on its icon and selecting reconnect inflow.

03:41

This is useful in situations where multiple manholes or

03:45

no manholes are contained within one sub catchment area.

03:49

Finally, from the tree view,

03:51

right click surface. To start the process of importing surface data,

03:56

select load surface

03:59

in the surface data menu, click load from

04:03

then in the load surface menu,

04:05

select imported surface from the data folder

04:09

back in the surface data menu,

04:11

click OK. To complete the import process.

04:14

A notification appears asking if you want to

04:17

update the existing accidents slash cover levels.

04:20

Using this surface data

04:23

you have options to update or keep all levels

04:25

and an option to manually maintain specific levels.

04:29

You select

04:31

for this exercise, keep all existing levels at their current values.

04:36

Double click one of the manholes to see

04:38

its details including its cover level and depth,

04:42

click cancel to exit the menu.

04:45

Keep in mind that importing different data sets does

04:48

not need to happen in a certain order.

04:51

In this case you could have started by importing surface

04:55

C. S. V. Or cad data first

04:58

by allowing this flexibility info,

05:00

drainage removes obstacles from the data import process
