New Data Products from the ISU GIS Facility: 24K Topo Maps 1949-1986


The ISU GIS Facility Manager, Robin McNeely, recently gave a presentation for the Iowa Geographic Information Council Lunch and Learn series about new data products that the GIS Facility has been producing. Here is a link to watch Robin’s presentation, which begins around (29:20): https://iastate.webex.com/iastate/ldr.php?RCID=64ed815f6c8eaa323fa5c88cc36d7d60.

She highlighted the completion of the Historic United States Geological Survey (USGS) 24,000 Topographic Map series ArcGIS service. The 24k historic topo maps were downloaded from the USGS TopoViewer as georeferenced .tif files, inventoried and put into an ArcGIS mosaic dataset. The dates for those maps for Iowa are 1949-1986. They are currently in a published map service on ortho.gis.iastate.edu and as a layer in the Iowa Geographic Map Server (see map below.)

Dear Teachers: A New Year, A New You!

As we begin this new year you may want to challenge yourself with a new skill. Esri has a 6-week program, Learn ArcGIS Educator Program for New Users, available to give you an introduction to many of the core applications available for the classroom. Each week you will spend time watching videos related to the topic, take notes, share you thoughts using Flipgrid and discussion boards. For more information and resources visit the Learn ArcGIS Educator Program Hub: https://learn-arcgis-educator-program-new-user-learngis.hub.arcgis.com/pages/welcome.

Landsat: Launching into A New Year

USGS just released a Story Map summary wrapping up 2021 and the exciting developments with the Landsat mission including a newly launched satellite and 10 million scenes in the archive mark two high points.

Here are some suggestions for doing this is ArcGIS Pro, within the Symbology tab, use the dropdown menus to adjust the color.

  • Change Stretch type to Minimum Maximum.
  • Also consider changing the Statistics from Dataset to DRA (Dynamic Range Adjustment). See the example below.
