FOSS4G SE in Knoxville 2019

· ·

…and the party continues on this end with another FOSS4G meeting in Knoxville.

Mark your Calendars – March 19th and 20th 2019 will be when this happens. Two things will change just a little:

  • We are tag teaming the event with Cumberland URISA . The one thing I’m a bit fuzzy on is price BUT – I will do what I can to keep it cheap for everyone.
  • Workshops! People asked for training so that’s happening. What kind of training? I have no clue BUT I do plan on doing the QGIS class in some capacity. I need other people to show up so: Grass? PostGIS? Lidar?

Which – I’m late on making the announcements. Things have been busy BUT – please make plans to attend. I’ll be sticking pricing and other news as I hear it on the wiki site.

FOSS4G-NA 2019

· ·

FOSS4G-NA popped up on my radar this week.

So from just the website and a few twitter noise makers it looks like It’s headed to Mission Beach California (San Diego) April 16-18 2019.  I’ve made the last 3 – so It looks like I’m going to do my best to make this one.  Road Trip? I encourage you to attend and support the FOSS4G North America Community.

20 minutes at the East TN TNGIC Meeting

· ·

I went through a year or so of not talking at conferences. For local ones I’d show up and do something. I taught a workshop at FOSS4GNA 2018. I did a workshop at FOSS4G 2017 in Boston (and it sorta sucked).  I need to get out of that mode and talk more – but I’m happier being quiet these days and working with clients.

Anyway – at FOSS4GNA 2018 I discovered something – the OSGEO Suite had disappeared from Boundless’s Website and was replaced with a github repository. It wasn’t long after Don Meltz put up an excellent explanation of the OSGEO Suite. The OSGEO Suite being gone isn’t a problem. It does increase the amount of talking I have to do spend explaining it’s not a problem. I could even compile the suite – but my clients can’t. They are smart people – but the time to compile the boundless suite won’t be happening.

One of the things I keep running into is the idea of an Open Source Server. The OSGEO Suite was well known and I get people asking “Hey – can you set us up a geo server”. They mean the opengeo suite. I then launch into an explanation of what makes up a “geo server” and they go a bit blank and answer me “Yeah – one of those”.

So for the next bit I’m gonna be doing something like this:

I want to explain how this works to people. We’ve gotten a bit deaf by hearing “ArcServer” at every conference in TN as this one monolithic thing you have to install to make a web map…which really don’t need since AGOL appeared but…you want SDE and it’s not called that and you have two people editing but you need SQl Server but you don’t….

Anyway,  QGIS/PostgreSQL/PostGIS I’ve installed multiple times and as of late I’m experimenting with geoserver and what it can/can’t do. I have no grand delusions of creating ‘Randy’s Open Geo Spatial Super Duper Server’.  I want to get to the point where maybe mapserver is an option in this. So much to learn…so little time.

I suck at github – but I’ve been more active as I try to develop a skill set and get over the angst of pushing and pulling things. I’ve built a vagrant box to install PostGIS/PostgreSQL/Geoserver so I can have something to point at plus it gives me a starting point for an upcoming class I’m in the middle of building. The vagrant box isn’t pretty – I expect to change it over the next bit as it’s mostly pieced together from a lot of other people’s work (Coleman McCormick, Dave Smith, etc). It works though and I have everything but pgadmin 4 running in one spot. Which – I don’t think this is anywhere near “install this for a server” because this is mostly just for talking, training, and testing.

So why vagrant? Why not docker? I can gloss over vagrant faster at theses talks than I can docker.  I have 16 minutes to draw diagrams and about 4 minutes to publish one piece of data: QGIS -> PostGIS -> Geoserver -> Leaflet.

Anyway – if you’re up for the possibility of a train wreck of a presentation come by the East Tennessee Meeting in Kingsport next week as I try to explain how this works and hopefully you get excited enough to install some or all of these components and do something cool with your data.

OSGEOLive 12.0

· ·

So for those of you going “HEY I WANT TO USE SOME OF THIS OPEN SOURCE SOFTWARE?”. Maybe you can’t install it locally…or maybe you have a spare machine laying around – there’s a way for you to do it.

Download the OSGEOLive image and run it as a virtual machine or boot your computer into the Distribution. It’s a Linux operating system with about 50 plus free and open source geospatial applications. 

They put a ton of effort into releasing this as a showcase of the software in the OSGEO realm. So give it a run and test out software you have questions about.

FOSS4GNA 2018

· ·

I love a good road trip. FOSS4GNA was in St Louis Missouri this year. Close enough for me to get in the car and tune out for 5 to 6 hours.

First thing on the Agenda – QGIS.  I did the 4 hour “Intro to QGIS” for about 60 something people. You had people who had worked around gis for a good while and were curious about this Open Source desktop. You had some people who had been using it and had questions. Overall it was a bit much with that many people – but worth the effort. I hope everyone walked out with something new they didn’t know. I was inspired – 4 years ago you’d scream “QGIS” and there were a few who knew. I think this year I’ve taught the 4 hour class to about 100 people. This is going well – watch for QGIS Part II coming shortly. I’m hopeful to do the 8 hour one at some point. Seriously – I know you people love 3.5 hours of me talking but the 8 hours of me talking is magnificent (it’s actually not).

I did a really technical “Copy and paste” of the paper abstracts as listed on the website and filtered out a few words that were throwing everything off.  You could pick and poke and over analyze this very happy looking word cloud a bunch – I wouldn’t. Do notice the giant work “DATA” in the middle of it though. There is a very small word: GIS. So I’ve gotten the question several times over the last bit “Why go to this one?”. My consulting life has taken a very data centric turn and to deal with that data I use open source tools. So I spend a lot of time talking to people at the conference. I spend time talking to the developers who make the software I like…at this conference. This one scratches an itch for me. There are a lot of smart people. It’s a good thing. if I go to an event and have all the answers what’s the point in going. So what I walked out with is this following:

  • I never heard “Big Data” – it was just data. The implication was there for it to be big. Hence you hear a lot of Machine Learning. I have only used machine learning in terrible Terminator Jokes and being snarky. It’s time to give it a look. It’s also time for all this machine learning to do a proper reboot of the Terminator franchise..
  • Python is my nemesis. I need to spend more time with it. If I heard that one word once I heard it half a dozen times. Which – no big deal it’s a tech conference but for me it stuck out more than usual. Maybe I’m more self conscience about it these days. If I count every programming thing I’ve ever done that has stuck – so far it’s been bash shell scripting from 26 years ago (that’s not even programming so much). I’ve just got to force myself into more cases where I have to use python.
  • All this machine learning is turning it’s collective head towards imagery. In a conference where I don’t hear a ton of “Raster” or just ignore it – suddenly raster was in my face everywhere.
  • Geopackage    – I feel like I’ve spent over a year going “PLEASE DON’T LET ME BE WRONG ABOUT GEOPACKAGE”. After this conference – I found it mentioned multiple times and the over arching theme seemed to be “it’s a thing now so deal with it”. With QGIS switching to geopackage as the default data format – I expect this grow over the rest of 2018.
  • I found myself walking in and out of conversations constantly. Sometimes I meant to stick my head in – sometimes the conversation found me. I missed several talks just for the fun of talking to other users/developers.
  • The nice thing with this open source software – there are smart people working on it. So what happens when you need improvements to the software? GDAL Barn Raising.   How much hay did they raise? 140k worth. So there are much needed improvements coming to gdal. It’s noteworthy looking at the companies that contributed. Yes ESRI is in there. So if you ever wondered – they see the value of the improvements. Open source GIS touches a lot of software.

Other noteworthy things:

  • Someone said “there’s a line at the women’s restroom”. If you stopped and took a look around – there were more women at this conference. I don’t have a number. There were more. There were about 527 total humans registered at the conference. I will guess higher than 35% for women. No numbers to back me up so deal with it.
  • The second thing I do is go look at a mirror and walk out and look at the crowd. I’m tired of seeing white middle aged balding bearded glasses wearing people at conferences. There were people of color at this conference. The colors varied. Not everyone was like me and that was a good thing.

If there was a keynote that stuck out – it was the final one.

Chris Holmes brought the conference to an end with a discussion…of….well….Deep Learning…Machine learning….imagery……..the idea of a queryable earth.  In other words there’s enough imagery being taken you should be able to “ask” it questions. Planet Labs it pulling down something like 10 terrabytes of imagery a day. One snapshot of the earth. A DAY. So train the computers to classify the imagery and start asking questions.

There was a lot more that happened. Walking across St Louis at night. Food. City Park. Talking to total strangers. Meeting random people I bump into over the interwebs and hassling them. I stuck my foot in the Mississippi River. I got to play Geohipster for a day and tweet random insanity.  Having served on multiple conference committees – I find I’m happier not on them.  This was a good event. I enjoyed it. I walked away feeling overwhelmed and hopeful for the path I’m barely scratching after 26 years. So where is FOSS4GNA in 2019? Stay Tuned.
