9:00 a.m., 11:00 a.m., and 3:00 p.m. (PDT)

You can analyze elevation and hydrologic data using the new Elevation Analysis services hosted in Esri ArcGIS Online. For example, you can find the slope of a road, calculate a viewshed, or discover where water flows to or from, using these services in ArcGIS Online, ArcGIS for Desktop, or other web clients.

To familiarize yourself with how to use these analytical capabilities, tune in to the live training seminar Elevation Analysis with ArcGIS Online on June 5, 2014.

After viewing this seminar, you will understand how to

  • Use terrain analysis tools to explore elevations along a particular path; identify visible areas; and calculate elevation, slope, and aspect for features that you select.
  • Use hydrologic analysis tools to determine watersheds and the downstream path of water based on a point that you choose.
  • Build custom web applications using the ArcGIS Online elevation analysis REST API, which is included in your ArcGIS Online organizational subscription.

This seminar will be of interest to GIS analysts who need to visualize terrain and perform raster-based analysis. ArcGIS Online users who want to work with elevation and hydrologic data, and developers who want to build web applications that consume elevation analysis services will also want to attend this seminar.

A basic understanding of ArcGIS for Desktop, ArcGIS Online, and geoprocessing is recommended.

You will need a broadband Internet connection and an Esri Global Account to watch the live training seminar. Creating an Esri Global Account is easy and free: visit esri.com/lts, click Login, and register your name and address.

When net neutrality backfires: Chile just killed free access to Wikipedia and Facebook

www.qz.com  By Leo Mirani May 30, 2014

Net neutrality is a sore subject in the United States. Proponents argue that allowing big companies to pay for faster data transfers to their customers would disadvantage start-up business that cannot afford such payments. They also say consumers could be forced to pay more for access to data-hungry services such as Netflix. Opponents of net neutrality say that those who use the most bandwidth should also be the ones paying the most for it. After all, the tubes that ferry data around the world are not public utilities—they are private business concerns.

A surprising decision in Chile shows what happens when policies of neutrality are applied without nuance. This week, Santiago put an end to the practice, widespread in developing countries, of big companies “zero-rating” access to their services. As Quartz has reported, companies such as Facebook, Google, Twitter and Wikipedia strike up deals with mobile operators around the world to offer a bare-bones version of their service without charging customers for the data.

It is not clear whether operators receive a fee from big companies, but it is clear why these deals are widespread. Internet giants like it because it encourages use of their services in places where consumers shy away from hefty data charges. Carriers like it because Facebook or Twitter serve as a gateway to the wider internet, introducing users to the wonders of the web and encouraging them to explore further afield—and to pay for data. And it’s not just commercial services that use the practice: Wikipedia has been an enthusiastic adopter of zero-rating as a way to spread its free, non-profit encyclopedia.

Designed to woo new users rather than those already connected to the internet, these free programs do not offer the full, whizz-bang version of the service in question. Facebook Zero is largely text-based; Google only provides access to a few of its services. And smartphones generally cannot access these sites. They are aimed squarely at poorer people with pre-paid connections and older phones.

But Chile’s Subsecretaria de Telecomunicaciones has decided (link in Spanish) that such promotions violate net neutrality laws and must end in two days, on June 1. According to the law (link in Spanish), internet service providers must “not arbitrarily distinguish content, applications or services, based on the source or ownership thereof” (translation by Google).

This is short-sighted. Chile’s mobile internet penetration is low by the standards of the Organisation for Economic Cooperation and Development (OECD), as the chart below shows.  Click to continue.
