The National Geodetic Survey (NGS) plans on retiring the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88).  They are hosting a webinar at the 2015 Geospatial Summit.  More information below:

For those who cannot attend the Geospatial Summit and Height Modernization Partner meetings in-person, NGS is pleased to announce webinar registration is now open. Use the links below to register, and additional webinar information (including audio and system requirements) can be found online: http://www.geodesy.noaa.gov/2015GeospatialSummit/. The webinars will also be recorded for later viewing.

As a reminder, here are brief descriptions of these meetings:
At the Geospatial Summit, NGS will provide updates regarding the planned replacement of its two primary geodetic datums: the North American Datum of 1983 (NAD 83) and the North American Vertical Datum of 1988 (NAVD 88). The summit will be an opportunity for federal and state agencies, as well other constituents, to share their comments, questions and concerns regarding the new geometric and geopotential datums, which are planned to be published in 2022.

The annual National Height Modernization Program Partner Meeting allows state and university partners to explain the best practices they develop and challenges they encounter when determining accurate heights in their local regions or communities. The meeting is also an opportunity for stakeholders to express their requirements as NGS continues to develop geodetic models and tools in preparation for the replacement of NAD 83 and NAVD 88.

USGS Hydrography Seminar Series

High-quality hydrographic data are critical to a broad range of government and private applications. Resource management, infrastructure planning, environmental monitoring, fisheries management, and disaster mitigation all depend on up-to-date, accurate, and high-quality hydrographic data.

The U.S. Geological Survey National Geospatial Program is initiating a new series of virtual seminars to highlight the uses of hydrographic data.  These seminars are intended to share success stories from users who have solved real world problems using hydrographic data, provide information about the National Hydrography Dataset and related products, and provide a virtual forum for users, similar to what might be encountered in a conference setting.

The first seminar will be held on April 9 at 2:00 PM ET.  The topic will be the response to the January 2014 Elk River chemical spill in West Virginia, specifically the use of the NHDPlus, real-time stream flow and velocity information from stream gages and models, and the Incident Command Tool for Drinking Water Protection application to limit effects of the spill on communities downstream.

These seminars will be presented every 6 to 8 weeks, featuring applications and speakers from different disciplines.  Connections are limited and pre-registration is required.

Hydro Seminar 1 – Incident Command Tool for Water
Guest speaker – Dr. William Samuels, Leidos
Thursday, April 9, 2015 – 2:00 PM Eastern Daylight Time
Register here.

After your request has been approved, you’ll receive instructions for joining the meeting.  In case the meeting is full, you will receive information on an alternate date.  For more information see: http://nhd.usgs.gov/HydrographySeminarSeries.html.

Security Vulnerability in Geocortex Viewer for HTML5

Posted on by

If you use Geocortex Viewer for HTML5, update your apps!

From Drew Millen, Geocortex Product Manager at Latitude Geographics Group:

Yesterday we were made aware of a potential security issue affecting all versions of Geocortex Viewer for HTML5, thanks to a vigilant customer contacting our Support team.  While we don’t know of any specific attacks that may have exploited this vulnerability amongst our customers, we take potential security issues very seriously. We’re happy to report that we were able to respond quickly, and a patch will be available for download in the Geocortex Support Center in the coming hours. The patch involves replacing a single JavaScript file and does not require a re-install or that you update Geocortex Essentials.   We recommend customers with applications that use Geocortex Viewer for HTML5 (all versions) apply the patch. Note that the upcoming release of Geocortex Viewer for HTML5 2.4 will not expose this vulnerability. Here’s what you need to know:

  • This issue potentially allows a malicious attacker to craft a viewer URL that loads configuration and code from a domain under their control.
  • This issue is a result of the way viewer configurations have historically been loaded. In the past, attempts to load configurations from other domains were prevented by the browser; however, newer browsers have evolved to support a technology called Cross-Origin Resource Sharing (CORS), which now allows cross-domain requests to be made.
  • An attacker can craft a link to a viewer on a trusted domain, such as http: //trusted/viewer/index.html, that loads their malicious configuration file from a machine that they control. If the attacker’s server is configured correctly, they can serve malicious code to users who have been fooled into clicking the link.
  • An example of a malicious link could be: http: //trusted/viewer/index.html?configBase=http://go.geocortex.com/e/61102/2015-03-26/3qh36/47536401resources/config/default/
  • All browsers supporting CORS — including ones in iOS and Android — are susceptible.

Here’s what we recommend you do:

  • Download the applicable patches we are making available in the Geocortex Support Center. Click the “Geocortex Viewer for HTML5” link and look for Security Update 2015-03-26.zip.
  • Read instructions.txt for notes regarding potential changes to viewer launch links in certain advanced scenarios.
  • Follow instructions.txt for instructions on applying the patch.

We apologize for any inconvenience this issue may cause you. Please get in touch with us if you have any questions or if we can help.
