Sain Associates’ Geographic Information Systems

Geographic Information Systems (GIS) data is at the root of millions of decisions worldwide. It is one of the cornerstones of any civil engineering project. At Sain Associates, we offer a full suite of GIS services. Our GIS data applications are essential for projects that need a solid foundation of well-developed, cost-effective enterprise systems that are custom fitted to our client’s needs. Our geographical data experts use several well-established GIS technology suites—and the latest GIS software—to offer a comprehensive suite of well-rounded services.

GIS Applications at Sain Associates

At Sain Associates, we evaluate existing client mapping and information systems, and create a strategic project plan for successfully implementing a GIS. Our team offers a range of services, like conversion to GIS from CAD, paper maps, and older GIS formats; development of new data from various sources; integration of other database systems with GIS; and cleanup, update, and correction of existing data. These and more are all part of our data services.

To meet the needs of our clients, Sain Associates employs multi-level quality control measures and automated computer procedures.

Why Use Geographic Information Systems?

While it might seem like too many map layers, geographical features, and data, GIS systems have several real-life applications that can benefit all projects. Here are some of the most practical reasons to implement geographic information systems in new projects.

Modeling Topology:

We can perform spatial modeling between geometric entities by analyzing topological relationships to determine adjacency, containment, and proximity.

Hydrological Simulation:

GIS hydrological models can add slope, aspect, and watershed variables to provide spatial element data other hydrological models lack. Because water always flows downward, terrain analysis is essential in hydrology. The direction of surface runoff and flow accumulation can be determined by slope and aspect.

Cartographic Design:

Cartographic modeling is the process of creating, processing, and analyzing several thematic layers for simulation or optimization models.


Interpolation is the process of creating a surface, typically a raster dataset, from data collected at several sample points. Digital elevation models, triangulated irregular networks, edge-finding algorithms, Thiessen polygons, Fourier analysis, (weighted) moving averages, inverse distance weighting, kriging, spline, and trend surface analysis are all mathematical methods for producing interpolative data.

Broadband Planning:

Sain Associates has developed a comprehensive, map-based approach to evaluating broadband infrastructure that incorporates the visual and spatial analytical aspects of GIS technology.
