GI Talk | IIT Kanpur | 21st March’2015 | Surabhi Gupta (surabhi_gupta@trimble.com)
Purpose of this talk
• To understand what “Research” is!!
• To discuss areas of research in Geoinformatics
• To know about some recent work in different areas
• To discuss about Geoinformatics scope in India
• The ultimate goal is to motivate you all to come up with
some new ideas of research
2
“Understanding deeper meaning of the word before actually doing it….”
Research is…
• Searching for and gathering information, usually to answer a particular
question or problem
• Presenting your own evaluative perspective
• Your research represents a synthesis of your own perceptions, attitudes,
ideas, and experiences supported by information gained from other
sources
• The goal is only achieved when you have –
 carefully and widely read what others have written on your topic
 analysed, compared and evaluated those ideas
 come up with your own conclusions
• Finally one’s own research idea can become a product
3
Research – 5 simple key steps
1.
Choose area of research
2.
Explore your domain
3.
Shape your ideas into a specific problem statement
4.
Cite sources relevant to your problem, evaluate and refine
the information gathered
5.
Come up with a conclusion or a solution depending on your
idea of research

Research scope in Geoinformatics
GI field is really “diverse”
3D modelling
Geographical
Information
Systems
(GIS)
Image
processing
Areas of
research
GPS
positioning
and
Navigation
Remote
sensing
Computer
vision
Photogramm
etry
Think and Implement
Lets discuss some examples of what people are doing in these
different areas
…..So that we can also contribute in future!! 

Aerial imagery
7
Trimble UX5 Aerial Imaging Solution
Product overview
• Aerial imaging solution
for fast and safe aerial data
collection
• Design includes camera
modified to capture nearinfrared (NIR) spectrum
• Apply imagery for crop scouting to detect pests, weeds,
mineral deficiencies, and other potential problems in agriculture
…..and this production method is PATENTED!!

Trimble UX5*….
Advanced
control
drone
design

• Capture 180 acres (73
hectares) of imagery at
one inch (2.5 cm)
resolution in a single
flight
• Operate in crosswinds up
to 37 mph (60 kph)
• Use reverse thrust for
precise landings in
confined spaces
Image
acquisition
Automated
workflows
• Optimal image quality along
with maximum
photogrammetric accuracy
• 24 MP camera and its
custom optics give the UX5
the ability to capture data
down to 2.0 cm (0.79 in)
resolution
• Trimble Access Aerial
Imaging application with
automated workflows
• Guides operator through the
pre- and post-flight
sequences with step-by-step
digital checklists
• Compute an orthomosaic, a
digital surface model, and a
3D point cloud from each
flight using the
photogrammetry module

3D mobile mapping

Mobile mapping: Indoors and outdoors
Zebedee*
• handheld 3D mobile mapping system developed at
CSIRO.
*Publication describing the technology:
M. Bosse, R. Zlot, and P. Flick, "Zebedee: Design of a Spring-Mounted 3-D Range Sensor with Application
to Mobile Mapping", IEEE Transactions on Robotics, 28(5), October 2012.
Zebedee…
Technology in brief
• Consists of a lightweight LiDAR scanner
• Approx. 30m (100ft) maximum range
• Industrial-grade MEMS inertial measurement unit (IMU) mounted on a simple
spring mechanism
• Scanner loosely oscillates about the spring, thereby producing rotational
motion that converts the LiDAR's inherent 2D scanning plane into a local 3D
field of view
• Sensor trajectory can be accurately and continuously calculated from the
laser and inertial measurements in real-time
• Range measurements can be projected into a common coordinate frame to
generate a 3D point cloud

Remote sensing

14
How NRSC/ISRO is using remote
sensing techniques…
• NRSC has been a major force in adoption and use of
geospatial technologies in our country
• NRSC focusses on –
 land use / land cover
 geology and geomorphology
 hazard assessment
 mineral exploration
 oceanography
 agriculture and forestry
 water resources monitoring
 land degradation monitoring
 environmental monitoring

3D Laser Scanning

Moedls (short for Mobile 3D Laser
Scanner)

How to scan the object for 3D printing in a cheaper way?
• An interesting project work by John Fehr*
• This is an app which runs on a smartphone
and can do high level 3D scanning
• Object scanning using rotating platform
and line laser
• Scan converted to point cloud or 3D data
• Rotating platform design has guide markers for aligning the camera and laser, and a
built-in accurate angle measurement
• Each laser comes in a custom enclosure with a 2.1mm power plug as well as an
external 2-AA battery power supply

Geoinformatics scope in India
• Major users of geoinformatics in India are Central and State governments and
most of the work is done in the field of remote sensing
• Some departments and agencies related to this field–
 National Remote Sensing Agency (NRSA Hyderabad),
 North East Space Application Centre, (NESAC Shillong)
 Regional Remote Sensing Application Centre (RRSAC Kharagpur,





Dehradun, Jodhpur, Nagpur and Bangalore)
Indian Space Research Organisation, (ISRO Bangalore)
Advanced Data Processing Research Institute (ADRIN Hyderabad)
Space Application Centre (SAC Ahmedabad)
Indian Agriculture Research Institute (IARI) and Indian Council of
Agriculture Research (ICAR).
State governments offer jobs in their individual National Informatics Centre
(NIC) and Space Application Centres
Geoinformatics scope in India..
• Apart from this, there are following sectors where its been utilized –
 environmental agencies
 national survey and mapping organisations
 mineral exploration
 utility companies
 emergency services
 public health and epidemiology
 crime mapping
 transportation and infrastructure
 tourist industry
………the only limit is the acute shortage of skilled professionals
19
Where we can contribute..
Research is not bounded…
One can be associated with some academic institution to do it
….Or start his own enterprise to come up with new product ideas
There is tremendous scope with accelerated growth and development
prospects..
…the only need is to think, research and contribute by going deep to
find a solution
So lets start thinking of a problem that need to be solved and the
research begins from there!!
