CONCLUSION 1.0 About BISAG:1. ABOUT BISAG The applications of space technologies and

geo-informatics contribute significantly towards socio-

economic development of the society.

Recognizing the importance and need of Space

technology

for

developmental planning purposes, the Government of

Gujarat established the Bhaskaracharya

Institute for Space Applications and Geo-informatics

(BISAG) in the year 1997, as the State

nodal agency to utilize space technology and geo-

and

geo-informatics

informatics for various developmental activities of the State.

1


Since its foundation, the Institute has experienced extensive growth in the spheres of space technology and geo-informatics. The objective with which BISAG was established is manifested in the extent of services its renders to almost all departments of the State. Year after year the institute has been endeavoring to increase its outreach to disseminate the use of geo-informatics up to grassroots level. In this span of eleven years, BISAG has assumed multi-dimensional roles and achieved several milestones to become an integral part of the development process of the Gujarat State. 2.0 ACTIVITIES OF BISAG BISAG’s activities are multi-fold and have expanded in a big way and focused on the following:

Satellite Communication

3.2 River & Drainage:The district at present is Traversed by 7 perennial rivers, the Sabarmati, the Hathmati, the Meshvo, the Mazum , the Vatrak, the Harnav and the Khari.

1


- The Sabarmati river flows from north to south along the western borders of the district.and other rivers flows from north-east to south-west. The Sabarmati originates in the outliers of the Arvalli. it has a total length of cover 300kms and an extensive catchment area. it originates in the Mevad hills of Rajasthan. it flows in 4 talukas of the district -Khedbrahma ,Idar ,Himmatnagar and Prantij. The rivers Sai, Hathmati , Harnav , Pamni joins the river Sabarmati. -The Hathmati river rises in the mewad hills of the Rajasthan state. it passes south-west about 56kms. throughout district. -TheMeshvo river originates in the Mewad hills of Rajasthan. it runs parallel to the river Khari about 202.77 kms. joins the river Vatrak near Kheda. -The Mazum and the Vatrak rivers are originates in the hills of Dungarpur of the Rajasthan . travelling respectively about 25.75kms south-west , 243kms south. -The Harnav river rises in the Madwa hills of Rajasthan, it enters district near the village Khokhara in the Vijaynagar taluka. it Passes through rocky and forest area

Physical Features:-The Eastern border of the district touching Rajasthan State, in other word the district can be divided in to 2 zones , the hilly region and the plains. The range of Aravali hills covers the northern and eastern part of the district and the south and south-east parts covering plain area.

Sabarkantha is Located at north Gujarat. The rainfall varies between 300mm in the North and north-east. The district experiences 3 different season. The hot season lasting from March to June, the Raining season from Mid June to September and the cold season extending from November to February. The highest temperature 40.5Ëšc and minimum 9.04Ëšc in the district.

4.0 DATA USED:4.1 SPATIAL DATA:4.1.1 Callateral Data:-

1 -Administrandrytive Boundries (State,District) at 1:50,000 Scale from Survey of India toposheet 2-Network of Roads,Drainage and Canals at 1;50,000 Scale from SOI toposheet Updates using latest Satellite Data from IRS LISS III 3-Soil map at 1:50,000 Scale Prepared by National Boureau of Soil Survey and Landuse planning (NBSS and LUP)Modified ,Simplified by BI SAG.These maps were digitized and Spatial database were Prepared in Arcmap using UTM projection system with modified Everest(earth model) referencing.

5.0 Methodology:5.1 Acquiring Raw data:-

1


Raw image received to BISAG from NRSA (National Remote Sensing Agency), Hydrabad. Acquiring raw data for geo-referencing Satellite image. Satellite Image is use in Analysis and interpretation. raw image considered to be the master image.

5.2 Geo-rectification:The Purpose of image rectification is to correct image data for destortion. Master image rectified with UTM (Universal transvers Mercator) projection system modified with Everest datum. Master image was referenced using GCP’s from 1:50,000 scale SURVEY OF INDIA (SOI) toposheet in Erdas Imagine 8.4. with Geomatric correction with polynominal order 1.

SATELLITE IMAGE INTERPRETATION:-

Classification:-

Image Classification combines visual analysis of Image data with quantitative techniques to automatically identify the features. in all cases the purpose of Classification process is to categories all pixels in a digital image in to classes or themes. This categories data are used to produce Thematic Maps or Land Cover in an Image. The classification Procedure fall in to 2 major categories 1) Supervised classification 2) Unsupervised classification. We used supervised classification to identification

6.1.1 SUPERVISED CLASSIFICATION:-

1


- 3 Basic steps involved in Supervised Classification.

-Training Stage -Classification Stage -Output Stage -Training Stage:The image analyst Identifies trainning areas & develops numerical description of spactral attributes of each Land Cover type. -Classification Stage :Each pixel in image data is classified in to the class to which is resemble the most. if the pixel doesn't resemble to any class according to algorithm it is classified as unknown. -Output Stage :After the entire dataset has in categories the results are represented in output stage 3 forms of output are produce - Thematic Maps - Statistical Tables - Digital data files

1


- Advantages of Supervised Classification:-

# Identify distinct specral classes which may not be visible to the analyst during trainning Stage.

Conclusion:1


The Agriculture is essential for Longturm sustainmblity and Increase Economical Condition. Sabakantha is Having Good Production Of Cotton, Wheat and Musterd. Earlier Sabakantha hadn’t good irrigation , then the crops are in poor condition but after Dharoi and Check-dams Provied good irrigation facilities which increse s in Production.
