WHAT IS GIS?
GIS is the field of study that makes computer generated interactive maps possible. Most people have seen flashy GIS maps on television news programs and shows like CSI. GIS.com provides this definition - "Geography is the study of locational and spatial trends about the earth's surface, the objects found on it, and the people who inhabit it. GIS technology provides a framework to manage, analyze, and disseminate geographic knowledge." See the Wikipedia for a complete definition.
SEMO GIS USER GROUP
The SEMO GIS user group was formed to promote knowledge of GIS in and around Southeast Missouri. Most of the group are "newbies" who are new to GIS. All interested persons are welcome. Everyone is encouraged to buy Getting to Know ArcGIS Desktop, 2nd ed., for an excellent introduction to GIS and a six month trial version of ArcGIS Desktop, available from Amazon.com for $37.77.
Garet Couch, a GIS consultant with Wind Environmental Services, LLC., gave the group a simple Excel Degree/Minute/Second to Decimal Degree calculator and detailed instructions on how to add X, Y coordinates to ArcMap. Thanks Garet!
Pat Stack, a Design Solutions Executive with Seiler Instrument, led the March User Group meeting. Pat brought several examples of Trimble GPS units and related equipment. He demonstrated some cutting edge GPS units and discussed their use, maintenance and software pricing. He led the group through an initial set up of Pathfinder Office. The group engaged in an excellent discussion of many GPS topics, including group pricing of Trimble units.
The November User Group meeting was attended by nine GIS and Health professionals and others interested in GIS. This unstructured meeting included group discussions on a variety of GIS related topics, including data sharing and HIPAA privacy rules, disaster preparedness in general and for special needs individuals, addressing, MERIS, and many others. This group is an excellent place to bring GIS questions and to hear top GIS professionals in this area's responses. Everyone with an interest in GIS is welcome to attend.
Eighteen people attended the May 2008 User Group hosted by two ESRI representatives, Lindsey Hunter and Jennifer Kuntz. Lindsey is this area's Sales Associate. She introduced herself and distributed ESRI mouse pads, cups, and product literature. Jennifer gave an informative and detailed presentation on Model Builder, including it's elements, construction and execution. Then, she discussed geodatabase types, uses, and differences, with info on subtypes, validation, topology, versioning and replication. This was one of the best and most informative User Group meetings ever.
The March 2008 User Group was attended by ten GIS professionals and interested people. The Group discussed Cape Girardeau County's GIS mapping site on EMapsPlus which is somewhat difficult to use, ESRI's licensing of tools, comparison of the Glaize Creek Project and Jefferson and Perry County maps at www.semogis.com, and the status of the statewide aerial photography flyover project. MSDIS now has these photos available to the public. However, the files are huge! MSDIS will provide the data to anyone who sends a portable hard drive to their office.

DISCUSSION LIST
Show-Me Net has created an email discussion list to improve communication among user group members and anyone interested in GIS in this area. Messages addressed to the group are delivered to everyone in the group. Everyone is invited to join. Click HERE to join.
SHOW-ME NET AND GIS
Show-Me Net has partnered with the SEMORP&EDC to gather data to promote community mapping by making highly detailed maps of this area available to local cities and counties and to anyone on the Internet. "Community Mapping is a process involving youth, citizens, community professionals, and community decision-makers working together to learn and use geospacial tools and data to address community and environmental issues." We now have a training and development server in operation. A fully functional GIS server should be on line in a week or so. Watch this page for progress reports.
