Getting to Know Esri Support: Brian C.

In keeping with tradition, we want to introduce you to another member of Esri Support Services, Brian C.  We talked to Brian about what he’s interested in, what hooked him on GIS, and what he likes about being in Support here in sunny Redlands, California. Keep an eye out for Brian at this year’s User Conference!

So Brian, how were you introduced to GIS and what grabbed your attention?

From a very young age, I was always fascinated by maps and would try to pinpoint where we were on family road trips. Later at the University of Akron, I was working towards a Secondary Education degree with a focus on History while enrolled in an Intro to Geography class. The professor talked about fields that utilized a degree in geography and mentioned GIS. I stayed after class and discussed it further with him. At the time, I was completely unaware that GIS existed, or that the University of Akron offered a degree program for it. The real draw for me was that I could learn to create maps similar to those I used growing up in Boy Scouts and on road trips. The following semester, I enrolled in a class about maps and map reading, as well as an Intro to GIS class. Midway through the first part of that semester, I made the decision to change my major, and I’ve never looked back.

What’s your current role at Esri?

I’m a Desktop Support Analyst. I primarily support ArcGIS for Desktop, ArcGIS Online, and raster technologies.

What’s the coolest thing about working for Esri?

Working with our customers. Everytime the phone rings, you get to see a different issue and possibly learn something new. Additionally, it’s really interesting to see how our customers are applying GIS to meet the needs of their organization.

Where are you from originally, and what do you like about living in Redlands? What do you miss about home?

I was born in Topeka, Kansas, but if you ask me where I’m from, I would say the South (Alabama and Georgia) and Northeast Ohio. While I was growing up, my family moved a fair amount, but I spent my most impressionable years in the South and in Ohio. My favorite thing about Redlands is its proximity to the outdoor activities I enjoy. In less than an hour’s drive, I can be deep in the mountains or completely lost in Joshua Tree National Park. The thing I miss the most about home would be the seasons. Being able to watch the leaves change and the snow fall were always my favorite times of the year.

If you could wake up tomorrow anywhere in the world, where would that be and why?

The Himalayas. Ever since I was a child, I have loved the mountains, and I would love to explore the regions that are home to some of the tallest mountains on the planet.

Some day, Brian, some day… thanks for your time!

Web Maps Must Be Updated if Using Styles that Adjust Symbol Size Automatically Based on Map Scale

This blog pertains to web maps and layer items that have both of these characteristics:

  • Web maps and layers authored with ArcGIS Online prior to the June 2016 update.
  • Contains polygon layers that are styled using Smart Mapping tools to adjust symbol size and/or outline width automatically based on scale

Smart Mapping tools allow you to select between various methods for using attribute values to drive the size of marker symbols when mapping data associated with polygons. You can specify a concrete size range for the symbols, or use automatic sizing so that they are optimized for the initial map zoom level and will automatically adjust so they look better across more zoom levels. We discovered an issue when using the automatic sizing option where the size of each symbol was being incorrectly represented in the web map with pixel values rather than point values (points are the correct unit of measure according to the web map specification). The ArcGIS API for JavaScript was also using pixel values. The result was inconsistent sizing between ArcGIS clients.

You also have the ability to automatically adjust the width of the outline of the polygon based on the current scale. Automatic sizing of polygon outline widths were also being represented using pixels rather than points.

Starting with the June update of ArcGIS Online, sizing values will be correctly represented using points which will enable marker sizing in web maps to be displayed consistently in all ArcGIS clients. The ArcGIS API 3.17 for JavaScript was also updated to use point values rather than pixels. While this update resolves the inconsistencies with auto sizing values going forward, it also means that web maps that were created before the June 2016 update of Online will have marker symbols and polygon outline widths that appear 1.3 times larger than the initial sizes you saw when originally authoring your map.

Example map with automatic sizing before the update            

Example map with automatic sizing after the update

What can you do if your web map was affected by this update?

If you created a web map or layer item in Online prior to the June update with layer styles that take advantage of automatic sizing based on scale, we recommend that you reauthor your web map. This process will resave your web map with the correct sizing values for consistent display in all ArcGIS clients. Here are the steps to reauthor your web map:

  1. Open your web map or layer item
  2. Click on “Change Style” in the layer menu for the polygon layer(s) that use automatic sizing of symbols. Note: You might want to write down the options you have selected so that you can easily reselect them in step 4.
  3. Select a different style for your symbols than you originally had selected and click “Done.”
  4. Click “Change Style” again on the same layer and reselect the original styling options you had, and click “Done.” Any options that were configured within the original style must be reconfigured.
  5. Save your web map or layer item. Your web map will now have size represented using point values.

For information on changing the style of your web map or layer item, see this help topic.

Note: this issue also occurs in web maps and layers that were created in Portal for ArcGIS and will be addressed in Portal for ArcGIS version 10.5. This article will be updated once a solution is available.

Getting Comfortable with JavaScript API 4.0

Now that the ArcGIS API for JavaScript 4.0 has been released for a couple of weeks, this is an excellent opportunity to take a walk through some of the new syntax and functionality. This blog will go through a sample 3D application focusing on the Search widget. You can follow along with the sample code from the Esri Developer Support GitHub repository, and run the hosted sample here: View it Live.

Functionality-wise, the app displays a 3D map with four widgets: Search, Zoom, Compass, and Attribution. By default, the View includes the latter three widgets, as described in the documentation. If you’re not familiar with the 4.x changes, all mapping apps contain a map and a view. The map holds the data, and the view contains the visualization information for that data. In other words, the map is the subject, and the view is the camera; complete with filters, modes, and settings. All 2D apps will have MapViews, and 3D apps will have SceneViews (note: the term ‘scene’ indicates three dimensions across ArcGIS). The same applies for maps from ArcGIS Online and Portal for ArcGIS: a WebMap is 2D, and a WebScene is 3D.

Google Chrome 51 Issues when Logging in to Portal for ArcGIS, ArcGIS Online, or Custom Apps

Update, 2 June 2016: Google Chrome 51.0.2704.79 was just released; it fixes the change that caused a blank screen for ArcGIS Online, Portal for ArcGIS, and applications built with the ArcGIS API for JavaScript. If you are affected by this, please click the Customize and control Google Chrome button and navigate to “Help > About Google Chrome” to force an update check and upgrade to this latest patch level.

The previous version was 51.0.2704.63, and the fixed version is 51.0.2704.79.

Update, 27 May 2016: KB 13156 has been published on the Support website to provide additional information about this issue.

———————

Google released an update to Google Chrome (version 51), which was pushed out to the public on Wednesday, May 25th. Unfortunately, this update included a change that impacts anyone using Google Chrome to access ArcGIS Online or Portal for ArcGIS versions 10.3, 10.3.1, 10.4, or 10.4.1.

This change impacts many apps built on the ArcGIS API for Javascript (versions 3.8 – 3.16), several subsets of custom apps built by users, partners, and Esri Professional Services (for example, any app that uses the feature table or an analysis widget), and, most notably, the “home app” in ArcGIS Online and Portal for ArcGIS.

You may be seeing a screen similar to this after logging in: a blank screen with few or no elements.

What you can do:

If you are using Google Chrome to access ArcGIS Online, the above listed Portal for ArcGIS versions, or apps built with the above-listed versions of the ArcGIS API for JavaScript, please turn off auto-update in your Chrome browser now. If Chrome was updated, you will need to temporarily use another browser (such as Internet Explorer or Mozilla Firefox) until patches have been released.

What Esri is doing:

  • The ArcGIS Online team is preparing fixes that will go live this evening.
  • We are still working on a solution for Portal for ArcGIS.
  • Developers using the hosted version of the JavaScript API are unaffected, as it has already been patched.
  • We are working on a solution for JavaScript API developers that use either a custom build of the API or use it locally.

We will provide updates at the top of this blog post regarding Portal for ArcGIS and ArcGIS API for JavaScript as soon as we have more information. A technical article has been released for this issue, KB 13156, which provides some additional detail about this problem.

If you have run into any problems as a result of this bug that impact your workflows, please contact Esri Support Services at 1-888-377-4575.
