Minnesota Geological Survey County Atlas Series C-29, part A Clay County, Minnesota Scale 1:100,000 Emily Bauer, Project Manager 2014 Digital products ------------------------------------------------------------------------ All digital data for the Clay County Geologic Atlas is provided in the zip file C29_dvd.zip. The title refers to the DVD available from the MGS where the data is available as shapefiles and ESRI grids and formated into an ArcGis project. The ArcGis projects are also available within the zip file. If you would prefer to have the digital data on DVD, contact our Map Sales Department at (612) 627-4780, ext. 238. Freeware versions of software to extract the zipped files are readily available for almost any platform (pc, Unix, Mac,..) for download via the web. All shapefiles are registered in UTM coordinates, Zone 15N, NAD83 projection. Metadata for the GIS files is provided in the metadata folder as xml documents and is included in the ArcGis metadata catalog system. Several metadata files are provided as Word documents. The published paper maps included in the geologic atlas can be viewed as pdf versions of the plates: plate1_db.pdf = data-base plate plate2_bg.pdf = bedrock geology plate plate3_sg.pdf = Quaternary (surficial) geology plate plate4_qstrat.pdf = glacial geology cross sections plate5_bt_dt_snd.pdf = bedrock topography; depth to bedrock; and sand distribution models plate C29_dvd.zip--Arcmap 10 and 10.2 mxd, shapefiles, and ESRI Grids, illustrating the geology of Clay County. The C29cgaClay10_2.mxd will not run under older versions of Arcmap. However shapefiles can be loaded into any other version. Also included in the C29_dvd.zip is a C29cgaClay.pmf file. This file is for the ESRI program ArcReader which can be downloaded freely from the esri.com web site (get the latest version). This will allow anyone without an ESRI GIS license to view the project data and maps, the limitation is that independent data cannot be added to the ArcReader project. The C29_dvd folder is obtained by downloading and unzipping the C29_dvd.zip file (supplementary gis data files) to the root level of the selected drive. The pdf maps should be viewed using Acrobat Reader 5.0 or higher for best results. If necessary, download the files as binary, not ASCII. They may also view better if downloaded to the local drive and then view with a PDF reader rather than trying to view them inside a browser. If you would like paper copies of the geologic plates; contact the MGS Map Sales office at 612-627-4780, ex. 238 and specify publication "County Atlas Series C-31, part A", or the County geologic atlas for Clay County.
