ESRI UC 2019 Day 2

Day 2, diving right in.



I started with an Arcade class.  Arcade is not a programming language.  It is not a replacement for python.  It is an expression language that can be used across all ESRI products.  It is not case sensitive.

  

TextFormatting.Newline - AGO does not support.  Boo....seriously, make things work everywhere before releasing!

  

The presenter recommended a book available on Amazon called "Writing Arcade Expressions" by Dave Allen.

  



My coworker and I met with some ESRI staff in the vendor area to discuss some problems we've been running into, and to get some help.  We discussed using a base64 encoded string for pictures in pop-ups (they didn't know how to do this), related tables in pop ups (no real way to do this with truly live data), vector tile packages to get our data out to custom apps, and how in the world are we getting duplicate global ids in globalid fields??  I also asked why federated servers, and one rep claimed it's easier to administer (false!), and they are forcing everyone to move this way so they make more money.  And also, uploaded videos only work in ONE place WITHIN ONE single style of story map.  Super lame.



I went to a class that afternoon about creating vector tiles.  Right before class started, who walked through the door next to me but someone I went through a FEMA Academy with ten years ago.  What a trip that was to get caught up on ten years.  So fun.

  



Vector tiles should be a json file export.  You can create indexes to tile.  The biggest thing about using vector tile packages is they support any projection!  Hallelujah. No more forcing everything to web mercator.  The presenter mentioned there are vector basemap blogs that can show you how to edit ESRI vector tiles, vector tile style editor in AGO, and style editor in ESRI github.  They went through using the create vector tile package tool, share package tool, and extract package tool to view.  You are able to have scale based symbology, share it as a web layer, and create offline vector tiles.  Word to the wise - ArcMap does not support vector tiles.

Happy GIS-ing!

What Inspires Me

I saw a questions posed on Quora that asked what inspires a GIS Enthusiast? The answer to this will be different for each person.  For me, it is the following. My first GIS job, I spent a lot of time working on preplanning apartment complexes and mobile home parks with the fire department.  This meant that every time a specific crew was working, I would be on a ridealong with them, driving around each complex, marking things down on a map.  We started simple, with addresses and fire hydrants. You see, there isn't an universal addressing standard for apartment complexes or mobile home parks.  Each apartment can have a letter, number, building number, building letter, address, and/or any combination of these.  At the time, the 911 software they were using could get them to the gate, but no further.  This meant precious minutes driving around until they found it.  Mobile home parks start out with the homes in numerical order, but as homes move away, the next one in takes the nex

Developers Summit 2018, Day 1

Image
I only saw one other GIS person on my flight out.  My flight was short and happier the further I got away from the snow.   The biggest news by far, is that Map Girl has been upgraded to Map Woman. They must have had a lot of complaints. When I walked into the Plenary Session, I wasn't quite sure where to sit to see the screen... They said this is the largest conference by far with over 2100 attendees.  The theme is "By developers, for developers." Monday they had a "spatial hackathon," and although I don't know what that means, I'm pretty sure my boss would win it. A little bit of time was spent talking about AR/VR, and a colleague from the state later said it reminded him of our demo at UVU for GIS day and that we "are on the leading edge of it."  High fives all around.  The only thing ESRI did that we haven't yet, is they added a viewshed in their cityscape AR app. Apparently it pays to get there early, becau

ESRI UC 2020 Day 1

What a year! Because of Covid/the Corona Virus/The Rona, the UC this year unfortunately was virtual.  I was super sad about this.  The UC is a fantastic reminder that I have a seriously cool job.  Being able to attend the UC in person, you are overwhelmed with people from around the world that also do GIS, which is a stark contrast to doing GIS in Utah and being one of very few. That being said, ESRI did a FANTASTIC job with the UC! Being virtual, I had ZERO issues with connecting to classes, listening to speakers, I never lost a connection or was kicked out or had lagging issues, and that is a huge feat! So, great job! Because it was virtual, there were only a handful of class offerings each  hour, and all from ESRI staff.  They also split the plenary sessions into one hour segments each day, instead of all day Monday.  I think that was a great idea. So Monday started with the Plenary.  There were over 80,000 people attending virtually! From around the world.  Can we take a moment
