    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello, &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I am working on developing a GIS.&amp;nbsp; The project integrates desktop, web, and mobile mapping.&amp;nbsp; The data will be collected, edited, analyzed, and visualized in the different environments.&amp;nbsp; I am having trouble choosing a map projection for my geodatabase and data.&amp;nbsp; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;The basic outline of the project is:&lt;/P&gt;&lt;P&gt;- data collection through a mobile device with a native application (built with AppStudio) using the device's GPS to collect location and a photo;&lt;/P&gt;&lt;P&gt;- data visualization along with limited editing and analysis in a web application (built with Web App Builder), including measuring; &lt;/P&gt;&lt;P&gt;- more advanced data editing and analysis on a desktop when required (however the system is designed to work primarily with the web and mobile applications).&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Since the data collection and use vary, I am unsure what projection to use.&amp;nbsp; My inclinations are:&lt;/P&gt;&lt;P&gt;- web mercator for the data display and use on the web map; although, I am not sure how that will affect the measuring or analysis in the web map;&lt;/P&gt;&lt;P&gt;- projected state plane for the desktop application since my data is over a small area (10 miles) or a geographic coordinate system using the NAD1983 datum;&lt;/P&gt;&lt;P&gt;- for the mobile application, it seems like WGS84 makes the most sense in order to work with the GPS on my phone.&amp;nbsp; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;What is the best projection to use when a project has such a variety of uses and applications for the data?&amp;nbsp; Should I choose a CRS for the desktop application and then reproject all of the data for the web and mobile applications?&amp;nbsp; Is it possible to reproject the data when serving it as a feature service?&amp;nbsp; Does an application made in App Studio convert the GPS coordinates for display on the map?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;What is the method for choosing a projection in these circumstances?&amp;nbsp; In projects that I have completed in the past, there has been one final format for the data, such as a paper map.&amp;nbsp; In this situation, however, there are a variety of uses.&amp;nbsp; &lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thank you for the assistance!&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
