This is a sponsored Content by Hexagon Geospatial. From this presentation how Hexagon Geospatial technologies were used to map the forest degradation happening due to cement industries in Lumshnong village in Meghalaya, India. Read detailed case study here: https://www.geospatialworld.net/article/saving-forest-lumshnong-satellite-images/

1. Saving Forest through
Satellite Images
A success case study from
Lumshnong, Meghalaya, India
by Hexagon Geospatial

2. About Lumshnong, Meghalaya, India
Known for its lush
green forests
Rich in minerals such
as limestone, coal,
shale, bauxite, and
laterite
A natural hotbed for
the cement industry.

3. About the Project
Measuring Impacts of Industrial Growth on Forest
Land through Remote Sensing in Lumshnong

4. Objectives of the Project
Map growth of cement
industries
Quantify change in forest
degradation
Monitor changes in land use
for better decision making

5. How Did Technology Aid?
Implementation of Hexagon Geospatial technology for monitoring the
growth of cement industries and the impact on forest land cover

6. Identified Key Geospatial Requirements
Satellite Data
used IRS LISS III temporal satellite images of
the years 2005, 2009 and 2011
Products
Used ERDAS IMAGINE®, tools with the IMAGINE
Expansion pack- DeltaCue and AutoSync
Functionality
provided Geo-referencing, co- registration and
change detection

7. Technology Benefits – ERDAS IMAGINE
About the Software
 ERDAS IMAGINE - The World's
Leading Geospatial Data Authoring
System
 Provides tools for all Remote
Sensing, Photogrammetry and GIS
processing needs
 Offers consolidated workflow,
smarter processing and dynamic
modeling
Benefits for the Project
 Used for image processing of
satellite data
 Supervised image classification of
study area
 Creating accurate forest and land
cover analysis

8. Technology Benefits – IMAGINE AutoSync
About the Extension
 IMAGINE AutoSync is part of the
IMAGINE Expansion pack available
for ERDAS IMAGINE®
 Provides Automatic Image
registration for ERDAS IMAGINE®
allowing users of all skill levels to
generate data free of misalignment
issues
Benefits for the Project
 Change detection process requires
tightly aligned images so that
artifacts from poor image
registration do not arise as a
byproduct of processing
 All images were geo-referenced
through IMAGINE AutoSync module
that is capable of pixel level co-
registration of time- 1 and time-2
images.

9. Technology Benefits - IMAGINE DeltaCue
About the Extension
 IMAGINE DeltaCue is the Change
Detection Software available as an
extension pack for ERDAS
IMAGINE®
 Simplifies the complexity of
change detection process and helps
both advanced and novice users
Benefits for the Project
 Automated image-to-image
normalisation process was
implemented to ensure the mean
and standard deviation of time-2
images match with the time-1
images
 Primary colour difference in
DeltaCue was used for change
detection and redness difference
algorithm was chosen for
identifying land-use changes from
forest land to deforested land.

10. Total Expansion of Cement Industrial Units between the years 2005
to 2011
Benchmarking the cement manufacturing units as epicenters, buffer areas of 5 to 10 kilometers were considered as study

11. IRS LISS III temporal satellite images of the years 2005, 2009 and
2011 were used
Supervised classification on the study area was done to categorise forest and non-forest land, with the forest land sub-
categorised by density levels – high density, medium density, and low density.

12. Hexagon Geospatial solutions
helped classify forest land
accurately, and observe changes
in forest cover over the years due
to expansion in the cement
industrial units in Lumshnong
