22. Conclusion  ESRI ArcIMS relies more heavily on middleware to convert multiple types of data, but these extra procedures of converting data formats may reduce the performance of web mapping significantly  ESRI is a great choice due to its large market share in the GIS industry and because it’s most easily integrated with ESRI GIS software  GeoMedia WebMap does not use proprietary software languages, therefore there’s better interoperability across a range of file formats from various databases and GIS vendors  Autodesk MapGuide uses SDF (spatial data file) to deliver data and mapping to the end user, which allows for faster delivery than ESRI Shapefiles and supports many formats without data conversion  A vendor’s client-side viewer may be limited to an HTML-based viewer depending on the bandwidth of the user’s network  In general all these criteria, and more, factor into finding the right Web Mapping package on the market and although it is a challenging implementation the reward of Web mapping services is very significant  In the future implementation procedures of web mapping services should be more simplified
