OnTerra Systems Company History:

Steady Growth As One of the Most Innovative Web Mapping Companies

In the early years, OnTerra Systems became known as one of the premier web mapping companies by developing custom, integrated software solutions for web mapping for a variety of clients, using Bing Maps. In 2010, OnTerra Systems used its web mapping expertise to expand into route optimization solutions and introduced RouteSavvy™, its flagship route optimization software. RouteSavvy is available in two forms: 1) RouteSavvy™ – a powerful, affordable route optimization solution designed specifically for small to mid-sized fleets, and 2) the RouteSavvy™ API – an application program interface that software developers can use to integrate RouteSavvy route optimization into software solutions they are developing.

In early 2011, OnTerra Systems introduced the MapSavvy product.  MapSavvy provides an inexpensive way to access Bing Maps images needed for practical business or government use based on WMS industry standards from the Open Geospatial Consortium (OGC). Such uses include research, or government purposes, such as aerial images that need to be included in architecture and engineering drawings, proposals, and reports; utility, transportation, and pipeline planning; Homeland Security; and any endeavor that requires detailed maps or high-resolution imagery.

All along its growth curve, OnTerra has offered affordable Bing Maps licensing, at one of the lowest entry price points on the market today (access starts at $500 per year).

As market demand for Web mapping services continues to grow, OnTerra Systems continues to observe what’s needed in the market, and bring Web mapping products and software services to market.
