The Butterfly Effect and Arcmap

Loren Muehlius

John Guthrie

We will follow a project which began as helping someone at Global Recordings Network, a missions organization, learn ArcMap. The project grew from this to creating an interactive map on the internet for the organization. Most of the webinar will be demonstrating the map and seeing how Leaflet and Enterprise ArcGIS Server were used to create the map.

Loren Muehlius (BS, Cartography, University of Wisconsin, 1976) worked at a regional planning agency in Wisconsin helping finish computerized mapping of land use. In 1986, he joined Global Mapping International (GMI) where he focused on helping missionaries with mapping. When GMI closed in 2017, Loren was fortunate to continue his missionary mapping work with LightSys Technology Services.

John Guthrie (BS, Syracuse University, 1978) started as a map surveyor for USGS. In 1986 he moved to Colorado and primarily worked in research for USGS. John has worked with ESRI web mapping products especially in relation to wildland fire and water resources. Though he retired in 2013, he is still working part-time for USGS. He volunteered for GMI and LightSys and has traveled to over 30 countries on short-term missions trips. He currently spends the winter with his wife Margaret in Arizona.
