GIS Workshop – Intro to ModelBuilder I

GraphicOn Wednesday 6/22 starting at 10:30am will be part I of the Intro to ModelBuilder workshop. This will be a one hour hands-on workshop covering the basic concepts and best practices for working with ModelBuilder and how to create custom tools from models.

ModelBuilder is an application in ArcGIS used to create and edit models or workflows, stringing together geoprocessing tools. The models can either run in ModelBuilder, setup to run as a tool in ArcToolbox or even exported to a Python script.

All attendees must have some basic knowledge of ArcGIS, and at least know how to add data, save a project file (mxd), and access tools in ArcToolbox.

GIS Workshop – Geocoding

geocodeWe will continue with the GIS summer workshop series with a workshop tomorrow, Wednesday 6/15 on  geocoding. There’s still plenty of room if you’d like to register.

Geocoding can be described as the process of translating addresses or other unique locations into spatial data, assigning coordinates and plotting them on a map. The process can seem deceptively easy given how easy it is to plot an address using any of the numerous services such as Google Maps, Yahoo, etc.

 That said, understanding what goes on under the hood and using that information can make a big difference on the accuracy of the results when performing geocoding in your own projects, especially if you are working with hundreds or even millions of addresses.

Understanding how to properly format your data, choosing the best base layer or road network based on the precision needed or date of the data, as well as taking advantage of tools in ArcGIS to help clean your data can make a big difference.

This hands-on workshop on geocoding will help understand how the geocoding process works and offer suggestions on making the right decisions throughout the whole process.

The Pentagon Papers Declassified

 

Forty years ago, parts of a document entitled "Report of the Office of the Secretary of Defense Vietnam Task Force" were leaked to news media and printed by the Washington Post and the New York Times as the Pentagon Papers. The original report, commissioned by Secretary of Defense Robert McNamara in 1967, was printed in only 15 copies. The leaked version provoked one of the most significant first amendment court cases in U.S. history. Now, to mark the 40th anniversary of the leak, the National Archives and Records Administration (NARA) has released the complete, declassified, unredacted version of the Pentagon Papers, all 47 volumes, 7000 pages of it.

NARA compiled the digital version from copies held in the presidential libraries of John F. Kennedy (Robert McNamara’s copy), Lyndon B. Johnson (Clark Clifford’s copy)  and Richard Nixon (unidentified copy). NARA estimates that approximately 34% of the material is available for the first time.
