Book List of 2019

List of Books I read in 2019 and their short summary

  1. Skin in the Game Nassim Taleb (Jan 2019):  Book had very interesting idea that old ideas/laws that have propagated from olden days “Lindy effect”(name after cheesecake store in NY burrough famous for longevity) survived and for reason (effective). Decision makers without actual “skin in the game” (no direct consequences impacted ) are not trust worthy and view w/ suspicion. Book was very disjointed and written like some blog posts without simple explanation. There were lot of good points but mostly covered by poorly written explanation with lots of snarky personal comments. Very hard to read through and had to push through to finish it.

Amazing story of luck, foritude, and focus to summitting Everest. They weren’t the first Americans to summit yet was the most difficult route to summit.
  7. Thanks a Thousand – AJ Jacob (March, 2019) : Very well written with lots of gentle personality coming through. While reading the book and more afterward, felt more appreciative of things and people around me. Not just to my immediate surroundings with family and friends but bigger circle of people and accomplishments of so many people past. After the book, I want to start my own Gratitude project by sending a copy of the book for close friends and hand written note explaining my appreciation and specifics of each individual’s things they’ve done for me over the years.

I attended 4 separate workshops for two days and attended 24 talk sessions for three days. Below are my summary notes. Highlight of the conference were keynotes from Paul Ramsey and Joe Cheng  

  • Workshop
  1. Browser-based Geoprocessing with Turf.js and leaflet
    • turf.js client-side geoprocessing using turf.js library and integrating with leaflet.js library to build webmap browser based simple geoprocessing application.  
  2. Classification of remote sensing images with the Orfeo ToolBox and QGIS
  3. From WebODM to QGIS

  4. Processing Lidar and UAV point cloud in GRASS GIS
    • Exploring capabilities of GRASS GIS 7.2 lidar point cloud data processing.

Conference Sessions:

Leveraging Open Source software to build data/mapping tools in local governmentChris Whong NYC Planing Lab

  • Talked about using various open source to build tool and applications
  • using AuthO, turf.js Cartoserver, mapbox-gl, React, Digital Ocean.
  • Lesson learned – use existing tools (no customized design/development) bootstrap, eliminate dependencies of large software 
  • build modular (example of Jane maps, name after Jane Jacobs) 

Why your map sucks and you don’t even know it – Will Cadell, Sparkgeo.com 

  • Map analytic company that analyzed 15 million user session. 
  • Results: 25% of users don’t touch the map, once it’s loaded, user doesn’t move around
  • Double loaded (multiple times) caused by bad coding
  • 10% of activities happens at very first 1% of the duration
  • Need to tell the “INTENT” of the story very quickly
  • Most users do not click to explore the map but pan continously 

Let them expire! – One company’s experience with fewer proprietary software licenses – Paul Wickman GIS technology Director RESPEC

  • Using QGIS to them was NOT alternative to Arc but other option
  • Open Source option is not just free but means value
  • “Price is what you pay, Value is what you get”
  • Reasons for migrations
    • Per user scale model won’t work for current ESRI licensing model
    • It’s about business with value and felt that ArcGIS value has dimished in value
    • Look for value not ideology and need to thought out the plan.  “I don’t need the drill, just a hole”

An Introduction to containerizing geospatial apps with Docker – James Milner, 3D Repo

  • Docker container is encapulated environment which runs application.https://docs.docker.com/get-started/
  • Docker eliminate “It works FINE in my machine but NOT yours” issue. Get rid of dependency issue.
  • Docker Container vs VM (virtual machine)
    • VM isolates everything (no OS access) but Docker container use native OS. 
    • Docker container means running docker images.
  • By not having to load OS separately (not like VM), you don’t lose efficiency. 
  • One can use docker image to load Geoserver + Postgis i.e. from Docker Hub https://hub.docker.com/r/crcsi/geoserver-postgis/

Offline First Mapping – Calvin Metcalf, AppGeo

  • Using Web Service Worker, this can intercept http request and can save the map tile locally. 
  • It is browser based script that runs in the background, separate from a web page
  • Service workers can periodic background sync & push notifications that normally require native application but can do them through the browser. 
  • Service workers currently only support Chrome and Firefox browsers.
  • Here is a good introductory implementation of this technology in blog writeup 

Advanced geospatial technologies: The new powerful GRASS GIS 7.2 release – Helena Mitasova, NC State University.

  • Not your old GRSS (Geographic Resources Analysis Support System)  from Army Corps of Engineering days, Fascinating story of GRASS GIS told by William Shatner back in 1987.
  • Lot of new features and capabilities including raster/vector data analysis, cartographic tools, image processing, advance LIDAR processing tools and many more with latest version of GRASS GIS.

R-Studio:  Coding as first resort – Joe Cheng (CTO of RStudio)

  • Most folks use coding as last resort after using GUI but speaker showed why it should be other way around. 
  • GUI – developed design by developer/designer
  • CLI – task directed by user themselves
  • Use code to extend functionality of existing such as QGIS to repeat and to scale. 
  • Main benefit of using code 
    • Concise
    • Highly interactive ( inform, return results after each line of code)
    • Fast iteration
  • R – John Chamber originator  is to give user ability to interact and explore data. This programming language is heavily based on statistics and visualization. 
  • R Studio contains many tools, map + text + graphic/table + narrative to compose data to tell story. 
  • Shiny – can generate fully interactive web map using R studio.
  • R Markdown – framework to crate html, report/PDF and dashboard. 

DIY Mapping with drones and open source in a humanitarian context – Dan Joseph, American Red Cross

  • Many reasons for DIY drone instead of commercial, off-the-shelf product.

Welcome to Pkgeo.com

My very first post! I would like to fill my blogs with various open source geospatial tools and use cases.  The main reason I’m writing this blog is for my “future” self where I can go back re-read things that I usually forget after awhile. 
My posts will divide into four main categories. 

  1. All things open source geospatial things (GIS).
  2. Topics around small drone use, tools and techniques.
  3. Notes from Books and Podcasts
  4. Biking/Skiing/Hiking, not necessarily in that order.
