Brief on recent project where data

from NRSC used

Preliminary Engineering-cum-Traffic (PET) Survey for Future

Dedicated Freight Corridors

Total length of DFC Corridors in this contract – 6390 Km

Time for completion of project – 3 years

Scope included design of new railway alignment,

preparation of plans and profiles on a scale of 1:2000(H)

and 1:200(V), estimation of cost, etc.

Planning of other infrastructure facilities e.g. Signalling &

Telecom, Overhead Electrification, Bridges, Tunnels, etc.

As per conventional survey, it was not possible to complete

the work within prescribed time period.

Work is being carried out using Satellite Imagery.

……..…..

For acquisition/distribution of remote sensing data

within India, license/permission from Government of

India, through nodal agency, shall be necessary.

……..

To cater to development needs of the country, the

NRSC of ISRO/DOS is vested with the authority to

acquire and disseminate all satellite remote sensing

data in India both from India and foreign satellite.

Brief on methodology adopted for

processing of satellite data

Ground Control Points (GCPs) were established using DGPS;

Vertical Control Points (VCPs) or TBMs were established for

determining elevation w.r.t. Mean Sea Level by connecting

with SOI Bench Marks.

Further processing included: Geo-referencing of Raw Imagery using GCPs and VCPs;

Digital Elevation Model (DEM) using corrected stereo-pairs;

Ortho-rectification using DEM and GCPs to produce rectified seamless

mosaic of the imagery;

Pan-sharpening of Panchromatic and Multi-spectral data;

Feature Extraction from Pan-sharpened Ortho-rectified imagery;

Preparation of updated base map by integrating features extracted from

Ortho-rectified imagery with features of SOI toposheets for further

planning and design of infrastructure projects;

PART-2

Area of Imagery ordered for detours = 10,000 SqKm.

Digital Globe – 8750 SqKm (NS & EW DFC)

Geo-Eye - 1250 SqKm (EC & Southern DFC)

Order was placed during the period from Oct’12 to Oct’13

Area of Imagery received - 5010 SqKm (NS & EW DFC)

Balance area not yet received - 4990 SqKm

Due to non-receipt of data in time, we are facing lot of

difficulty in meeting our targets;

Many attempts to contact the vendor - Digital Globe/GeoEye,

for confirmation of time schedule & delivery of balance data

have not been successful.

Major issues in acquisition of Satellite Data through

NRSC

Long process – At least four stages till receipt of data;

The process is applicable irrespective of the size of project;

Time is essence of contract – Three stages of transition and

requirement of original signed document at each stage, there

is uncertainty in maintaining the time schedule;

No direct control over the vendor;

All Customers not technical experts - neither in finalization

of specifications nor checking of received data;

NRSC to contribute in checking of data received for:

Cloud cover

Off-Nadir Angle

Other quality parameters

Issues in acquisition of Satellite Data through NRSC

Contd…

Higher cloud cover (more than 15%) or poor quality of

imagery noticed at planning stage and requiring

replacement, is again followed by three way transition;

We have noticed problems of cloud cover in about 16% of

the data received for East-Coast DFC, which needs

replacement;

Use of imagery has increased in India for various

applications including land revenue, agricultural land,

infrastructure planning, etc., so NRSC should open offices

in major cities of India for co-ordination and/or other

services.

Benefits:

Meeting with Statutory Government of India Policy;

No compromise on security/sensitive installations in

the country as these are masked;

world.

Proposal for improvement in acquisition of

Satellite Data through NRSC

In case of procurement of Survey of India (SOI) Toposheets,

country areas are marked as Open, Restricted and Secret

depending upon the sensitive nature of that area and there are

standard guidelines for procurement of such toposheets.

Similarly, procurement of Imagery in the areas identified as

Open as per SOI guidelines should be direct through the

supplier (Indian or foreign) by Central/State Govt. Depts./PSUs.

All vendors, registered to sell imagery in India, should not be

allowed to sell the imagery directly for Restricted/Secret areas.

Procurement of Imagery in the areas identified as Restricted

and Secret should be through NRSC only and NRSC should

frame guidelines for the same.
