The Project Presentation focuses on the land use and land cover change pattern of Gurupavanapuri and environs, an area which is in the State of Kerala , India.
The work was mainly aimed to identify the rapid urbanization that took over in the Gurupavanapuri and its environs during the year 2002 and 2017 and on analysis there was a clear reduction of natural vegetated area due to the human influenced constructions.
The Project was completed using The ArcGis which is a GIS application. Remote Sensing data collection, such as SRTM DEM, ETOPO1 data (Bathymetry and Oceanic bedrock surface) has been achieved.

2. INTRODUCTION
• Urbanization refers to the increasing number of people that live in
urban areas. Land-use change is often associated with a change in land
cover.
• There are different factors and mechanisms drive land use and land
cover transformation such as climate, technology, and economics.
• GIS is a technology that enhances the users’ application to visualize
the spatially distributed nature of the data. GIS allows us to view,
understand, and interpret data in many ways that reveal relationships,
pattern and trends in the form of maps, charts and reports.
• The present study is using a Remote sensing data to monitor the
landuse changes through time.
3. STUDY AREA
• Gurupavanapuri and environs is one of the most developing cities and fast
growing city in the Guruvayoor.
• The study addressing the land-use and land-cover to determine land use
pattern and estimate the changes that have taken place between 2002 and
2017, Gurupavanapuri and environs, Thrissur, Kerala
• The total area is 50.8259 ha (approx. half a km. sq.) bounded by N. Lat 10° 35'
51.61"and N 10° 35' 37.11"and E. Long. 76° 2' 12.68" and 76° 2'
42.17“
• Many of these changes can be quantified from satellite measurements,
Google Earth, Aerial photographs.

8. Objectives
The main objectives of the research are as following:
• Monitoring of the urbanization expansion and land cover changes
since 2002 till 2017 in Gurupavanapuri and environs, Thrissur District
• Topography contour map and detecting the slope for the area.
• Preparing TIN model and drainage map.
• Preparing Bathymetry and Oceanic bedrock Surface Off - Thrissur
• Gain the knowledge of handling the spatial data by remote sensing
and GIS.
9. METHODOLOGY
• Considering the remotely sensed data of the two period times to
extract information about the LULC.
• Literature review of the LULC of any area as well.
• Remote Sensing data collection, such as SRTM DEM, ETOPO1 data
(Bathymetry and Oceanic bedrock surface), Google Earth images of
the area for 2002 and 2017 and other relevant materials.
• Data verification, preparation/processing Re-projection/setting of
coordinate system, clipping, digitizing, classification, etc. and
importing in personal/file Geodatabases.

13. Land use -Land cover
• To achieve this study the two different land covers and land use
classes of years 2002 and 2017 were analyzed.
• The values is estimated from digitization quantify the change in each
land cover category.
• The LULC of the study area that is being estimated is categorized in
to three classes

22. Contour map or Topographic Maps
These are general-use maps at medium scales that present elevation (contour lines),
hydrography, geographic place names, and a variety of cultural features.

23. Digital Elevation Model (DEM)
is a specialized database that represents the relief of a surface between points of known
elevation as a layer in GIS symbolized by a color ramp to produce new surfaces such as slope
and aspect.

24. Triangular Irregular Networks (TIN)
TINs are a form of vector-based digital geographic data and are constructed by triangulating a
set of points connected by edges. Visual representation of a topographical features and
appearance of the physical land surface.

25. Drainage Pattern
It is the study of the way in which the pattern of streams in a drainage basin is organized

26. Slope
A slope is a surface that is at an angle, so that one end is higher than the other.

27. Bathymetry
Bathymetry is the study of underwater depth of lake or ocean floors.

28. Oceanic bedrock Surface
Oceanic bedrock is the oceanic crust which is the uppermost layer of the oceanic portion of a tectonic plate

29. CONCLUSIONS
• Remote sensing and GIS is a valuable technique for handling the
spatial data.
• The built-up growth shows radical urban growth when compared to
that of the built-up where it has almost doubled in the year 2002.
• All these observations point towards the change in the land use pattern
and the study clearly defines this change, which can be used in the
future planning of Gurupavanapuri and similar areas.
