When we began this company back in 1969, we felt an almost limitless enthusiasm for the possibilities of geographic information systems (GIS). We understood even then that this new geographic information system technology could bring about a better future.
Our confidence in GIS is built on the belief that geography matters. It fundamentally influences and connects our many cultures and societies. As you explore our Web site, you will find abundant evidence that GIS technology is improving our quality of life by supporting more analytical decision making.
