SITE VISIT - REPORT
DATE: 20 JUNE 2019 TIME: 10:00am to 4.00 pm
VENUE: Karnataka Geospatial Data Centre, Koramangala Block II NAME OF THE COMPANY: Survey of India, Department of Science &
Technology, Govt. of India
TARGET AUDIENCE: STUDENTS OF 3 Semester and 5 Semester BTech in Civil Engineering
FACULTY MEMBERS: Dr Sirisha Uppaluri, Dr. Jacob Alex and Prof. Sarath Chandra
Lab Technician: Mr. Gnana Velu Objective
The main objective of the site visit was to create awareness among the students about advanced surveying and mapping techniques which are useful in Natural Resource Management, Disaster Management and Urban Planning and Management. Survey of India is the oldest Engineering Department in India and is responsible for precise positioning, Navigation and Mapping. Students were exposed to practical aspects 3 Dimensional and 2 Dimensional mapping techniques in ESRI’s Arc GIS, Leica Geosystem’s Photogrammetric Suite and
MicroStation Software packages to post process the Drone based images and stereoscopic Carto Sat data sets. Currently they are handling a project on Property Mapping for Revenue Department of Karnataka and Coastal Hazardous Mapping sponsored by world Bank Project.
Demonstration was given to the students to delineate the linear and real features from Drone Imagery with GSD of 20 to 30 mm. Students were having a hands-on experience to visualise the rectified 3D model of stereoscopic images by wearing anaglyph 3D Spectacles to delineate contours of 2 m interval. SOI personnel gave a demo on TRINITY + Hybrid Drone which they have acquired recently.
Students were divided into three groups and were sent to different sections of KGDC, Survey of India. First batch of students were taken to demonestrate on Hybrid Drone, second batch of students were taken to Cartography Section and third Batch of students to Photogrammetry section. On rotation basis demonstration was given to each batch on the project they are currently working on.
Mr. Satyendra, In-charge of Cartography section demonstrated on the Large scale mapping using Aerial Photographs in Arc GIS software. Mrs Salila and Mr.
Ravindra from the Photogrammetry section demonstrated on the stereoscopic mapping methods. Students were asked to wear anaglyph glasses to visualise the 3D model and explained how to delineate contours.
Mr. V.N Katti, Technical Officer, SOI has made arrangements to show the Exhibition room where they have displayed ancient to recent maps with various map projection and models.
Students visualised the map projections (UTM Polyconic and Conformal Conical) taught in class room lectures and understood the concept.
In the afternoon demonstration on Hybrid Drone (VTOL and HTOL) was provided. Demonstration on Flying was not possible due to high wind speed.
At the conclusion, Dr. Stalin, Director, Survey of India addressed the students at 3.30 PM. He explained the importance and functions of Survey of India and their current projects in hand. He also addressed the importance of large-scale mapping in Urban Contest.
He showed the Ground Control Point (GCP) established in their campus and explained how they measure the position on regular basis by keeping differential GPS for 3 days continuously on GCP to get independent coordinates.
He has also explained the importance of International and National permanent bench marks for precise positioning Globally and nationally.
Finally, he spoke about the various positions in Survey of India for Civil engineers and motivated the students to write IES and join Survey of India at officer level.
Students also got an opportunity to visit the Map Sales Office in the campus and topographical map sheets of Bengaluru was procured from SOI.
Learning Outcomes of the visit to Survey of India:
1. Learnt about the functioning of Survey of India
2. Understood the advantages of Stereoscopic and Monoscopic Mapping 3. Got awareness about various GIS and Image Processing software packages
useful for processing of satellite images, aerial photographs and Drone images for large scale mapping.
