    Recommended Datum Transformation to Use with RIGIS Data

    Datum transformations help you to more accurately re-project a GIS dataset from one coordinate system to another. Selecting an appropriate datum transformation is a stumbling block for many GIS users when they mashup datasets that use different coordinate systems. Esri ArcGIS Desktop and Pro software have a robust project-on-the-fly system, however it’s worth taking a look at the datum transformation method the next time you’re adding a new dataset that uses a different coordinate system than your map’s. Here at RIGIS, we’re continuing to use Esri’s “NAD_1983_To_WGS_1984_5” datum transformation when projecting data between Rhode Island State Plane NAD83 U.S. Survey Feet (EPSG 3438) and coordinate systems that use the WGS84…

    Recently I authored a blog post for the Environmental Data Center blog on setting up a feature class and Web Map for use with Esri’s Collector App. Based on discussions at previous RIGIS Executive Committee Meetings, I thought this posting may be of use and interest to the RIGIS community – especially the municipal-based RIGIS community. This workflow walks users through the process of setting up domains within a file geodatabase, applying these domains to a feature class, preparing the feature class for use with the Collector App, uploading the feature class as a Service to ArcGIS Online and then configuring the Service and Web Map in ArcGIS Online. The…

    Recap: RIGIS User Group Imagery Seminar

    On August 19, an educational forum on aerial and satellite imagery available for Rhode Island was held at the University of Rhode Island’s (URI) main campus with the goal of informing attendees on a variety of online resources for image data of Rhode Island, with a heavy emphasis on RIGIS and the US Geological Survey (USGS); this forum also highlighted the new suite of ArcGIS Image Services featuring RIGIS data that are being developed by the Rhode IslandView. There are three ways to download imagery from RIGIS. The majority of RIGIS imagery is available as tiled GeoTIFF and JPEG2000 format files, however historical imagery is available as tiled MrSID format files…
