Hydrological model represents hydrological cycle i.e. movement of water and energy between atmosphere and earth in the form of evapo-transpiration, precipitation, infiltration, percolation, ground water recharge, lateral subsurface flow, surface runoff and water storage. Hydrological model could be built on varying temporal and spatial scales. Hydrological models having more number of hydrological parameters represent real world situation. We provide varied solutions by integrating hydrological models with GIS and Remote Sensing techniques such as analyses of the movement of water and energy between vegetation, soil surface and atmosphere; flood risk assessment; river basin modeling at spatial and temporal scales, to study the global environmental changes; rainfall-runoff estimation; climate change application; surface water modeling; groundwater modeling; SWAT modeling; management of water reservoirs; dynamic modeling in GIS environment; erosion prediction; drought prediction; dust storm prediction; analysis of desertification; analysis of grassland degradation; water quality assessment; soil moisture mapping; prediction of evapo-transpiration; ground water recharge assessment; river flow forecast with real time meteorological data and crop pattern analysis.
GIS for Minor Irrigation tanks facilitates in the better analysis of minor irrigation tanks status through geospatial solutions, to understand the need of repair, restoration and rehabilitation works and there implementation in a systematic manner. GIS database helps to take better decisions such as to improve catchment area of tanks, to recharge ground water, to increase storage capacity of water bodies and to accomplish increased agricultural productivity. GIS helps to identify new minor irrigation tanks to enhance groundwater recharge. Accrete Geo integrates GIS in tank development plans, helps to take right decisions to improve water management, optimize cropping patterns and enhance agricultural and horticultural production.
Transportation is the platform for rapid urbanization in developing countries. Provision of effective transportation facility avoids congestion, pollution and cost. Network analysis is done using Remote Sensing and Geographic Information System techniques with due consideration of time and cost factors. GIS environment provides a better optimization of route and transportation network of tourist places. Effective transportation networks can be implemented using Remote Sensing data and Geographic Information System. Accrete Geo provides facilities such as, shortest path analysis, search closest facility, location-allocation to meet supply and demand of resources, study spatial distribution of resources through a network. GIS in Railway management facilitates in providing safety and security on time, weather alerts, train location, management of track, eases environmental assessment, management of communication and signal, management of design and construction, management of real estate, management of maintenance and systematic planning.
Mining requires spatial knowledge of earth’s crust resources both at surface and sub-surface level. Integrating GIS with mining and geology facilitates to operate mines with optimum efficacy. We provide a platform to acquire data, store, analyze and build a decision support system for engineering design and production management. GIS facilitates to create a 2D or 3D visualization, to better understand spatial relationships of mining site.
Satellite data facilitates in assessing topography and geology of a region defining the type of rock, soil and physical properties. Assessment of stability of slopes in selecting river-crossing sites for bridges and pipelines; and study of river erosion in sites prone to scouring, could be done by using remote sensing data and GIS techniques. Site selection for regional planning of large commercial airports, harbors, industrial towns and recreational sites is eased by using GIS and Remote Sensing techniques. We help in choosing the best site, meeting your project requirement. We help in choosing the best site, meeting your project requirements.
Geography of the earth plays an important role in the Archaeological survey with respect to level of exposure of archaeological sites and the impact of anthropogenic activities and natural forces on Archaeological discoveries. GIS based archaeological survey eases the documentation and monitoring of the archaeological discoveries. Detailed documentation could be maintained in GIS database such as, archaeological, technological and geographical components of archaeological sites. Monitoring of archaeological founds through GIS facilitates in understanding the level of preservation required and to take correct decision in the maintenance. Research on archaeological founds with GIS, facilitates in understanding spatial relationships such as clustering, intervisibility, proximity, orientation etc. Important tasks during survey and excavation could be better handled with site-level GIS. 3D models of archaeological founds facilitates in understanding the spatial relationships. Broader audience could be educated by integrating web-based GIS to Archaeological survey. We do GIS based Archaeological survey projects and help in documenting and monitoring Archaeological discoveries.
AccreteGeo facilitates in Tourism related works with the help of GIS technology. GIS is beneficial to both tourists and tourism developing authorities. Tourists could avail the advantage of GIS by visualizing tourist places in the form of photos and videos and get to know about the place with important information. Using GIS, tourists could obtain information such as optimal route plan, accommodation, cultural events, specialty of the places and interesting places to visit very easily. Integrating tourism into Web-based GIS eases the availability of the information and provides interactive maps for users query. Tourism developing authorities could incorporate GIS into their projects to ease the implementation of projects. Authorities could obtain the information of current infrastructure such as transportation, utilities and plan for the future requirements. Effective regional planning could be undertaken. New site selection for improving tourism could be identified using GIS, by considering parameters such as availability of space, existing utilities available and need to upgrade existing transportation infrastructure to meet the future requirements.
Spatial interpolation is a process to estimate the values at unknown points, using values of known points. Spatial interpolation facilitates in using sample data to create a surface data, which could be used for analyzing and managing. We facilitate in spatial interpolation in terms of both global and local methods. . Local methods include Theissen polygons, density estimation, inverse distance weighted and Thin-plate splines. Theissen polygon works on the assumption that, “every unsampled point within a polygon is closer to the polygon’s known point than any other known points”. Density estimation uses distribution of points and point values to measure densities in a raster. Inverse distance weighted approach works on the condition that, “unknown value of a point is influenced more by nearby points than by those farther away”. Thin-plate splines build a surface passing through points with the least possible changes in slope at all points. Global methods include trend surface and regression models. Trend surface model builds an approximate surface using points with known values and a polynomial equation. Regression model estimates a dependent variable using number of independent variables. Kriging a stochastic local interpolation method works on the assumption that a spatially correlated component is included in the spatial variation of an attribute.
Linear programming aims at optimizing the system resources in complex situations. Linear Programming along with Geographic Information System and Remote Sensing data helps in modeling real problem and improves spatial data management. Geographic Information System is a tool for integrating and analyzing geographically referenced data. Integration of Linear Program and Geographic Information System is useful in the application fields of hydrology, soil erosion, forestry and land use planning. It is essential for sensitivity analysis. We integrate GIS and Remote Sensing techniques with Linear Programming, to result in optimized solutions for transportation services, future urban development, water supply, cropping pattern, etc.
