With the advent of very high Resolution sensors (IRS 1C/1D LISS-III at 23.25m
and PAN at 5.8m), IKONOS-CARTERRA (MSS – 4 mts and PAN at 1 meter), Natural
Resource Mapping, AM/FM, Disaster Management, Resource Targeting (Ground
Water, Mineral Resources, Oil and Gas); Biomass Studies, Biodiversity, Vegetation
and Agricultural Mapping etc. all have undergone a sea change from the earlier
days of course resolution. Combining this with the power of GIS has given
a distinct advantage for mapping,modelling and targetting :three vital zones
of Resource Management. |

HOPE Consulting Inc.,
plays a pivotal role in providing turnkey solutions in GIS/DIP and DP based
Resource Data Management, Targeting, Disaster Management and AM/FM. It uses
high level of Digital Image Processing (DIP)/Image Interpretation and Digital
Photogrammetry for CORE APPLICATIONS IN THEMATIC MAPPING. Our main competence
areas are:
- Thematic mapping (LU/LC,soil,geology & structure,vegetation,geomorphology
etc.)
- Groundwater Targeting/Watershed Delineation/Drainage
Densities
- Geresource Utility Maps (GUM) at 1:12500
(IRS LISS-III + PAN) to 1:3400 (IKONOS – PAN) for AM/FM
- Satellite Image Maps (SIM at 1:3400 to 1:12500)
- Change Detections
- Natural Hazard Management / Risk Potential

AUTOMATED MAPPING
/ FACILITY MANAGEMENT
Turn-key solutions on electric and water supply, gas, telecommunication
networking (including cellular networking ), transport network/Alternate
Route Alignment ; Landuse development, planning etc. The other GIS Applications
includes Facility Management (FM) i.e. support, plan, update and display
of civic facilities (sewer, water, electricity/telephone cables, hospitals,
roads, parks, schools, other public utilities including locations & police
/ Fire stations etc.), Land parcel boundaries, inventory of public / Govt.
owned property ; transportation / route planning etc. with the generous
use of DGPS (GPS in differential) many of such FM utilities can be a base
for precision surveys. |

VALUE ADDED REMOTE SENSING PRODUCTS (VARSEPS)
New applications of existing RS products are emerging in the wake of several
high spatial Resolution (1-Meter) RS satellites in orbit and being launched
in coming months, such as Space Imaging’s IKONOS (in orbit) , Earth Watch’s
QUICK BIRD, Orbimage’s ORBVIEW and ISRO’s CARTOSAT and TES (Test Evaluation
Satellite on 1 meter PAN and 3.8 meters in MSS).In thematic mapping & FM
sector the high Sp. Res. RS data will influence significant changes. One
meter resolution and 2-meter horizontal accuracy will let customers to create
1:24000 maps without any ground control, which means they can make detailed
maps for areas they can’t even visit. If at all, ground control is available,
presently we can prepare a map at 1:2400 scale from IKONOS images.
Applications : Environmental management, mission planning, land use
mapping, urban planning and Revenue / tax assessments,Insurance, large scale
Civil planning.
Mapping with imagery as generally believed will not be limited only on photogrammetric
issues (measuring distances, locating objects), but also features extraction
will increase manifold with the combination of Four band multispectral data
and 1-meter panchromatic imagery, available as 11-bit data. This also offers
a greater dynamic range in spectral information e.g. Crop descrimination,
agro-forestry and agro-horticulatural practices.
Insurance/Real Estate Sector :- High sp. Res. VARSEP’S can be a very effective
tool for insurance sector, MultiNationals, Real Estate Agents, Municipalities
and even lawyers and media persons. Demonstrations utilizing imagery, especially
in 3-D, offer powerful evidence in court cases, particularly in Environmental
remediation cases where lawyers need to establish historical land conditions
and in case of Natural Disaster: how the insured property looked before
the disaster in a 2-D and 3-D maps.
Virtual Reality Maps :- The traditional 2-D maps are defined as ‘abstraction
of reality’, i.e. they represent the features sensu-stricto. However, computer
simulated 3D maps (basically DTM’s) are given some dramatic effects to create
VIRTUAL REALITY MAPS. These maps can be defined as the ‘Visualization of
virtual reality by adding virtual conditions to reality’. The existing DTM’s
or DEM’s (Digital Elevation models) are given pre-determined effects like
changing illumination, climatic, shade and shadow conditions and several
value added thematic maps can be generated such as : coloured hill shaded
maps; slope stability maps; Drainage and watershed map; Mountain landscape
Map; Solar Energy Map. These maps or VADP’s are highly useful for various
project management’s.
GIS data base Modelling:- SSPM based multi-thematic data integration
in Arc Info,Map Info and Microstation for Utility based Maps. Large scale
data conversion and OO GIS data bases for various applications.
