AUTHORS: Eric Herman, NYS Thruway Authority

ABSTRACT: Over the past several years, the Web Mercator projection has become the de facto standard for global web mapping services. Consequently, it’s also become a standard for many web GIS applications. Although this projection offers a number of benefits, users should be aware of the significant measurement distortions in that can arise when using this projection. Earlier iterations of Esri’s web application development tools required explicitly dealing with measurement corrections. However, the current out-of-the-box application development tools go a long way to helping ensure end users get more reliable measurements. This presentation will review the issue, and how the Thruway Authority’s use of the evolving Esri tools has helped deal with it.
