Geographic Information Systems (GIS)

Digital orthophoto with planimetric features in a GISSurdex helps clients design Geographic Information Systems (GIS) to meet their needs. A GIS is used to view, manage and analyze geospatial data. Some applications of this GIS data include:

  • Economic and industrial development
  • Land use and planning
  • Emergency response systems
  • Resource management
  • Tax assessment
  • Health and human services

Surdex will help you plan your project to achieve the optimal functionality, combined with superior imagery.

The key to a successful GIS is functionality – that is, does it perform those tasks desired by the user? The effectiveness of a GIS is determined by the mapping scale and resolution of the imagery. The better the resolution, the more detail is visible on the image.

However, better resolution costs more; for the sake of economy, it is necessary to determine the desired functionality of the GIS, and then obtain the resolution required for that functionality. For example, if a municipality wants to identify manhole covers, this would require imagery at 0.5’ ground pixel resolution; imagery at 1.0’ would cost less, but it would prove insufficient for the intended function.

Surdex helps clients realize and achieve their GIS goals by discussing their short- and long-term needs, offering options and making specific recommendations. We will work to develop a database design, customize GIS applications and provide an implementation plan for achieving your goals in a timely and cost-effective manner.
