Spatial decisions are influenced by diverse criteria - socio-economic and market factors, engineering design standards, environmental regulations, technical feasibility and financial costs. Satisfying these criteria often requires adoption of conflicting approaches, which makes problem solving a complex exercise. To find optimal solutions in such situations, we use a combination of
    i) problem definition frameworks
   ii) primary / secondary data
   iii) geo-spatial and statistical analysis and
   iv) engineering and business knowledge

We engage with clients either on a retainership or on a project specific basis. The geographic location of the project site is usually never a constraint. We can procure and process spatial data sets for most locations on the globe. This enables us to support international clients having remote project sites just as effectively as our Indian customers.

Our services encompass : Project site selection

A new manufacturing plant, airport, real estate development, check dam, wind power turbine or even a bank branch represents a significant long term investment for the owner. Site selection for such facilities is a strategic decision as it impacts design, construction and operational efficiency. The two key dimensions of site selection - physical and locational characteristics - determine whether the site can satisfy the functional and operational objectives of a particular land use. Strong interrelationships between physical and location characteristics necessitates their joint evaluation. Physical attributes include size / shape of the site, its topography, underlying soil/rock conditions, zoning restrictions applicable etc. Locational characteristics relate to the linkages between the site and facilities available in its neighbourhood - civic amenities, transport infrastructure and educational, employment, commercial, and leisure establishments. We can synthesize geo-spatial data from satellite images and GPS surveys, with CAD drawings such as site plans and market survey data to identify and measure these variables and their interrelationships.

Route selection

Construction of railway lines, roads, pipelines and power transmission lines poses many engineering, logistics, social and environmental challenges. Route and alignment selection plays a very important role in managing the challenges. These critical infrastructure assets will have to cross roads, rivers, railway lines, or forests through varied, often inaccessible, terrain. Pipelines should have suitable hydraulic design and provide easy access for product delivery and operational maintenance. Railway alignments have stringent gradient and curvature constraints. Smooth transitions are required between straight and curved sections necessitating the use of spiral curves. Tunnels and high viaducts are preferably avoided. However, in certain sections (e.g. forest areas) tunneling may be the only permissible option. Besides there are seismic/geologic considerations and issues related to right of way acquisition. At Omega Analytics, we create terrain models from stereo images and use GIS tools and mathematical programming techniques to examine multiple alignments and suggest optimal solutions based on evaluation of cost and non-cost factors. We produce detailed plan, profile and section drawings along with accurate estimates of cut-fill volumes.

Drainage and irrigation canal network planning

Deciding the canal alignment is a very important step in the planning of an irrigation canal project. Topographic conditions primarily determine the layout of the irrigation network. It is advantageous to align canals on ridges to ensure gravity irrigation on both sides. This reduces the need to construct cross-drainage structures across the canals. The command area would extend to the natural drainage channels on either side of the canal. The same approach is usually adopted for other parts of the network such as the secondary and tertiary channels.

Closely allied to irrigation planning is the subject of drainage. The irrigation network has to be linked to drainage channels as excess water is harmful to crop production. Our knowledge of terrain modeling and hydraulics and experience in canal mapping will be an asset to irrigation and drainage planners.

Flood estimation and bridge hydraulics studies

Highways and railway lines usually have a large number of bridges built across streams and rivers. Knowledge of flood hydrology and bridge hydraulics is crucial in determining the waterway and depth of foundation required to safely negotiate the flood discharge. The waterway should be wide enough to pass the design flood without incurring excessive costs of large spans. We estimate peak floods from the physiography of the catchment, historical data on storm rainfall intensities and land cover analysis. Unit hydrographs and rational methods are used based on the size of catchments. This is followed by detailed hydraulic modeling using channel cross sections and slopes as data inputs to estimate water surface profiles and flow velocities.

Digital image processing and interpretation

All our projects involve aspects of photogrammetry, image processing tasks such as rectification, contrast enhancement, classification and integration with other geographically referenced data sets. This experience enables us to work on a wide range of Remote Sensing applications such as land use / land cover mapping, Digital Elevation Model (DEM) generation for terrain analysis, agricultural crop type classification and area estimation, urban and regional planning, Environmental Impact Analysis etc.

Traffic Surveys

Traffic Surveys involve detailed study of conditions within an area or section to assess traffic volume prospects. The objective is to understand the financial implications of new /widening/additional line road and rail projects. Traffic surveys require forecasts of passenger and freight traffic likely to be generated in the catchment area over the useful life of the asset and the inter-modal transportation mix that would meet the demand. Traffic estimates have to be made using an origin-destination approach. Locations of population centres, agricultural production, commerce and industry need to be identified. Demographic data has to be integrated to enable robust analysis. Revenue projections and estimates of capital investments and operational expenses have to be prepared with care and judgment. Omega Analytics, with its expertise in market surveys, financial risk assessment and geo-spatial analysis, brings tremendous value to such engagements.
