Upload Layer
Available Types:
1. Upload Shapefile which was
present in zip format
2. Upload CSV file with added
columns (which was downloaded
previously)
• Upload Shape file
• Step:
– Select shapefile from local file system
– Click on upload button
– Click on refresh to see the effect of uploaded layer
note.
• Zip file name should be same as internal shapefile
name
Select any one of the 3
formats to upload
(then click on browse button to
Open browse window)
• Upload CSV File:
Procedure:
1. select geometry type
2. Select file through file browser (this file will
contain newly added columns with type
information)
3. Identify the original table with which it has
to combine
4. click Upload to upload csv file into
database.
Identify the layer with which
the newly added layer has to join
(table name in database)
Follow the similar procedure that was
Mentioned in previous case
(but here it csv file)
Download Layer
Procedure:
1. Select a layer name from list of
available layers in dropdown box
2. Select the layer format to download
from available formats
Layer To be downloaded
(select from list of available layers)
Available format to download
(save the file in respective folder)
WPS
Vector Analysis
• WPS: allows to do
processing on
existing layers
• Click WPS button in
Processing Services
(Tools)
• Right now processing
services are only on
vector , later on
other tools can be
added
•
•
Popup opens
User has to select
the processing
algorithm(ex:Buffer,intersection)
that he wants to
apply on layer
Example1: Buffer
• On selecting processing
algorithm (buffer) ,Its
corresponding required
inputs will be
displayed.
• Input1 : Layer to be
selected from
dropdown
• Input2 : width is the
area that will be
covered by layer.
• Value of width is a user
defined values.
•
•
•
Input1 : Layer selected
Campus:bus_stop
Input2 : Width : 0.5
Click on Execute
•
•
•
After clicking Execute
Button The Geometry
results of processing
on Campus:bus_stop
layer will be shown
below in text area.
User can further click
on View on Map
button to view results
on map in the
background
User can click on save
result as GML to save
the result as gml file.
Resultant Layer
•
•
Clicking on View
on map will
display the
resultant
geometry from
processing
service(buffer) on
layer.
bus_stop:buffer
will be displayed
in the Tree Panel
• Save Layer as GML
Example 2 : Intersection
•
Prakasam:manda
l_boundary layer
Example continued……..
• Prakasam:soillat
erite layer
Click Execute
• Click on execute after
selecting
layer1(prakasam:ma
ndal_boundary) and
layer2(prakasam:soil
Laterite)
•
•
•
•
After click on execute
the result is displayed
in TextArea.
Enter Layer Name for
the Layer to be seen in
Tree panel
View on map displays
the Results on Map.
Save as GML save the
results as GML.
Intersection Result
• Intersection
layer created
and it is over
layed on
prakasam:dist
rict_boundary
layer.
• Save as GML
STYLER
Functionalities
Basic Styler
• Single Symbol
• Labelling
Advanced Styler
• Graduated(Equal Intervals etc)
• Unique Value
IITB GIS Framework - Styler
Prakasam:mandal_
density layer is
selected
Basic Styler : 1)Single Symbol
• Changing color of
Fill and stroke
properties from
purple to
green(colors are
taken as hex
codes).
• Some other
styling properties
are opacity ,
width etc.
Single Symbol OutPut
• The properties
of
prakasam:man
dal_density
has been
changed.
2)Labelling
• Applied labelling
by
mandal_nam(attr
ibute) with Single
Symbology.
Labeling Output
• Labels has
been
applied.
Advanced : 3)Graduated –classify
•
•
•
Classify on
Numeric data by
creating classes
of equal
intervals.
8 classes created
on
attribute(numeri
c) density_1.
ALSO label the
classification by
mandal_nam
Graduated Output
• 8 classes
has been
created on
numeric
data and
has been
labeled.
4)Unique Value
• Categorize with
unique value in
a
attribute(chara
cter data type)
Unique Value Output
• Categor
ized
accordi
ng to
Unique
Values
FUTURE SCOPE
• Add Network Analysis Tools
- Route creation from given data.
- Shortest Path under given Constraints
• Raster Analysis Tools
- use WCS-WCPS for analysis
Network Analysis
• Route creation
Create automatically the graph database for
Transport using line and point data.
• Shortest path
To find the shortest path from source to
destination via designated route.
Raster Analysis
• Tools to do some processing on Raster –
clipping , raster to vector conversion etc
• Also incorporate WCS-WCPS(web coverage
processing services) which provides services
for raster coverages.
