GEOREFRENCING ON TOPO SHEETS STEP 1- OPEN ARC GIS MAP AND ADD DATA SHEET

4 | P a g e

STEP 2- OPEN CATALOUGE BOX AND SELECT A FILE AND CLICK ON NEW AND CREATE DATABASE

TABLE

NEW DATABASE TABLE CREATED IN TABLE OF CONTENT AND TEN OPEN IT

5 | P a g e

STEP 3 -AFTER THAT TABLE WILL FORMED THEN CLICK ON THE TABLE OPTIONS AND SELECT ON

THE ADD FIELD AND ADD NEW FIELD NAMED LATTITUDE(LATT) AND CLICK ON THE TYPE AND

SELECT DOUBLE AND SELECT ON FIELD PROPERTIES AND TYPE PRECISION=13 AND SCALE=6 AND

DO SAME ON ANOTHER FILED ADD ANOTHER FILED NAMED LONGITUTUDE(LONG)

STEP 4 -AND THE NEW TABLE WILL BE CREATED WITH LATT AND LONG AFTER THIS CLICK ON

THE EDITOR AND START EDITING THEN THE OTHER COLOUMNS WILL BE CREATED IN THE TABLE

6 | P a g e

NOW TYPE THE CORDINATES ON THE TABLE WHICH IS GIVEN ON THE TOPOSHEET, DO ZOOM TO

LAYER ON THE TOPOSHEET AND SEE THE CORDINATES OF LATTITUDE AND LONGITUDE,

CORDINATES SHOULD BE START FROM CLOCKWISE

DO THE SAME PROCESS WITH THE OTHER CORDINATEDS AND AT LAST IT WILL GIVE THE TABLE

NOW SAVE EDITS AND STOP EDITING

7 | P a g e

STEP 5-NOW CLICK ON THE NEW DATABASE TABLE AND OPEN IT AND CHECK DISPLAY X-Y DATA

CHECK WHETHER IT IS WRONG OR RIGHT AND CHECK LONGITUDE IS ON X-FIELD AND

LATTITUDE IS ON Y-LATTITUDE AND CORDINATE SYSYTEM (WSG 1984)

8 | P a g e

NOW THE POINT SHAPEFILE WILL BE FORMED NOW CLICK ON IT AND SELECT ZOOM TO LAYER

THE FOUR POINTS WILL BE DISPLAYED ON THE SCREEN

9 | P a g e

STEP 6-NOW CLICK ON THE GEOREFRENCING AND ADD CONTROL POINTS AND DO ZOOM TO

LAYER ON THE TOPOSHEET FOUR POINTS WILL BE SEEN NOW CHOOSE ADD CONTROL POINT

TOOL AND SEELECT ON THE FIRST POINT DO THE SAME PROCESS IN ALL FOUR CORDINATES AND

AFTER THAT CLICK ON THE GEOREFRENCING AND SELECT RECTIFY IT AND CHECK WHETHER IT

IS IN TIFF OR NOT ANS SAVE IT.

10 | P a g e

11 | P a g e

MASKING OF TOPOSHEETS STEP 1-OPEN ARC GIS AND ADD DATA (TOPOSHEET) FILE IN TIFF FORMAT

12 | P a g e

STEP 2 -NOW GO TO THE CATALOG AND GAVE THE LOCATION TO THE FILE AND CREATE NEW

SHAPEFILE

NOW GIVE THE NAME (MASK) AND SELECT FEATURE TYPE POLYGON AND IMPORT CORDINATE

SYSTEM WSG 1984

13 | P a g e

NEW POLYGON SHAPEFILE WILL BE FOMED IN TABLE OF CONTENT WHICH IS NAMED MASK

STEP 3- NOW CLICK ON THE EDITOR AND START EDITING AFTER THAT CLICK ON THE CREATE

FEATURE AND START EDITING FROM THE FIRST CORNER AND START EDITING

14 | P a g e

DO THE SAME PROCESS IN ALL FOUR CORNER AND THE RESULT WILL BE

NOW CLICK ON THE EDITOR SAVE EDITS AND STOP EDITING

STEP 4- NOW CLICK ON THE ARC TOOL BOX AND SELECT SPATIAL ANALYST TOOL SELCT

EXTRACTION AND FINALLY SELECT EXTRACT BY MASK

15 | P a g e

EXTRACT BY MASK WILL BE OPENED NOW FIILL THE INPUT RASTER DATA, FEATURE MASK

DATA AND OUTPUT RASTER

NOW NEW MASKED FIE WILL BE FORMED AND AT THE RIGHT CORNER THERE IS A SIGN WHICH

SHOW EXTRACT BY MASK IS CORRECT

16 | P a g e

STEP 5 -NOW ZOOM TO LAYER ON TIFF FILE AND THE RESULTS WILL BE FORMED

17 | P a g e

MOSAICING OF TWO TOPOSHEETS STEP 1- OPEN ARC GIS NOW ADD TWO MASKED DATA FILE (TOPOSHEETS) WHICH IS IN TIFF

FORMAT

NOW GO TO THE ARCTOOL BOX AND SELECT DATA MANAGEMENT TOOL AND CLICK ON RASTER

AND NOW SELECT RASTER DATASHEET AND SELECT MOSAIC TO NEW RASTER

18 | P a g e

NOW FILL ALL THE DATA ON THE MOSAIC TO NEW RASTER

AFTER THAT THE NEW MOSAIC FILE WILL BE FORMED WHICH IS NAMED MOSAIC AND AT THE

RIGHT CORNER YOU HAVE SEEN GREEN SIGH WHICH SHOWS THE MOSAIC TO NEW RASTER

PROCESS IS CORRECT

AND THE FINAL RESULT WILL BE FORMED

IMAGE CLASSIFICATIONS

STEP 1: OPEN AN IMAGE IN ARCGIS.

SELECT CATALOG OPTION ON THE RIGHT SIDE OF THE SCREEN. SELECT THE FOLDER THAT

COMPRISES THE IMAGE TO BE OPENED. DRAG THE IMAGE IN ARCGIS WINDOW.

STEP 2: SELECTING IMAGE CLASSIFICATION OPTION.

21 | P a g e

STEP 3: CREATING A TRAINING SAMPLE.

LEFT CLICK ON THE DRAW POLYGON OPTION AND DIGITIZE A POLYGON FOR A PARTICULAR

CLASSIFICATION. FOR EXAMPLE: A WATER BODY. (PIXELS OF A PARTICULAR RESOLUTION AND

COLOUR WILL BE SELECTED AND FURTHER CLASSIFIED.) SELECT THE TRAINING SAMPLE

MANAGER OPTION AND UPDATE THE INFORMATION LIKE COLOUR. COLUMN OF VALUE AND

COUNT WILL BE UPDATED AUTOMATICALLY.

STEP 5: CREATING SIMILAR TRAINING SAMPLES.

REPEAT STEP 3 AGAIN AND CREATE MORE TRAINING SAMPLES FOR IMAGE

CLASSIFICATION. (LIKE GREEN AREAS, RESIDENTIAL AREAS ETC.) UPDATE THE

INFORMATION OF ALL THE TRAINING SAMPLES CREATED.

STEP 6: IMAGE CLASSIFICATION

CLICK ON CLASSIFICATION, THEN SELECT INTERACTIVE SUPERVISED CLASSIFICATION.

IT EXECUTES MAXIMUM LIKELIHOOD CLASSIFICATION USING SAMPLE SET.

: RIGHT CLICK ON THE TOOLBAR AND SELECT THE IMAGE CLASSIFICATION. A DIALOGUE BOX OF

IMAGE CLASSIFICATION WILL APPEAR ON THE WINDOW. THE DIALOGUE BOX COMPRISES OF

TRAINING SAMPLE MANAGER, DRAW POLYGON OPTION, SELECT TRAINING SAMPLE AND CLEAR

TRAINING SAMPLE OPTION. THE IMAGE THAT HAS TO BE CLASSIFIED WILL BE PRE-SELECTED.

22 | P a g e

UPDATE THE INFORMATION OF ALL THE TRAINING SAMPLES CREATED.

STEP 7: FINAL OUTPUT

THE SYSTEM WILL GENERATE AN OUTPUT THAT WILL CLASSIFY THE IMAGE ACCORDING TO THE

LIKELIHOOD OF SAMPLES. THE FINAL RESULT WILL LOOK LIKE THE FIGURE SHOWN.

23 | P a g e

STEPS FOR DIGITIZATION STEP 1: OPENING THE SHAPE FILE IN ARCGIS.

STEP 2: EDITING THE SHAPE FILE.

SELECT THE SHAPE FILE WHICH YOU WANT TO EDIT FROM THE TABLE OF CONTENTS. RIGHT

CLICK ON THE SHAPE FILE > EDIT FEATURES > START EDITING.

24 | P a g e

ANOTHER WAY OF EDITING IS BY SELECTING EDITOR OPTION ON THE TOOLBAR > START

EDITING OPTION.

STEP 3: CREATING FEATURES.

AFTER SELECTING THE START EDITING OPTION, CLICK ON CREATE FEATURES OPTION ON THE

TOOLBAR. A DIALOG BOX WILL APPEAR. SELECT THE SHAPE FILE YOU WANT TO EDIT.

25 | P a g e

A DIALOG BOX ‘CREATE NEW SHAPE FILE’ WILL APPEAR ON THE SCREEN. NAME THE SHAPE

FILE AND SELECT THE FEATURE TYPE OF THE SHAPE FILE (POINT, POLYLINE, POLYGON,

MULTILINE, AND MULTIPATCH).

STEP 3: ASSIGNING THE CO-ORDINATE SYSTEM.

AFTER NAMING THE SHAPE FILE AND SELECTING THE FEATURE TYPE, ASSIGN THE CO-ORDINATE

SYSTEM TO THE SHAPE FILE. CLICK ON EDIT OPTION IN THE SAME DIALOG BOX. FURTHER A
