Apps are analogous to race cars and data are like drivers. Apps can be shiny. They get a lot of attention. Most apps are seemingly intuitive, especially the good ones. However, one with bad data is like a race car with a bad driver.
When building an app, do you know from where your data is coming and understand the support level and limitations of that data? These are important questions to guarantee that you are getting the best data possible. Read more about my thoughts on this subject in my blog, linked below.
Need additional information regarding the GIS products we produce? Let me know and I can fill you in on all we have to offer. If you're attending the ESRI Partner Conference (March 4–6) and the Developer Summit (March 6–10), you can also find me there. We have a booth at the expo for the Partner Conference and I'll be happy to answer any questions you have!
