I consider myself an artist and scientist. I’ll confess I have let the art go fallow some in recent years, but these are two sides of one coin. If you like either, and especially if you like both, you should check out Tobias Research. I met Michele at FOSS4G, where from the moment she saw my presentation on OpenDroneMap to using it to create a … Continue reading OpenDroneMap — Art and Science
Ok, I misunderstood… . The Null Island Archipelago is actually meant to be just datum based, i.e. not the 0,0 of every projection, but the 0,0 of every null lat/lon. @mizmay Someone suggested & @schuyler tweeted (who? please remind me!) a few weeks ago that each coordinate reference system (CRS) has it’s own Null Island, and therefore there must be a Null Archipelago. … Continue reading Null Archipelago — Null Islands for All Coordinate Reference Systems — revision
@mizmay Someone suggested & @schuyler tweeted (who? please remind me!) a few weeks ago that each coordinate reference system (CRS) has it’s own Null Island, and therefore there must be a Null Archipelago. This got me thinking — what does that look like? Enter PostGIS. We’ll create a function, that given an EPSG code will return the 0,0 location for that reference system in the … Continue reading Null Archipelago — Null Islands for All Coordinate Reference Systems
Let us expand a bit on the theme of Free and Open Source Software as _Folk_ software development, i. e. of the people, for the people, and by the people. When I put together my presentation for FOSS4G Korea 2014, I had elements of this theme in it. I expected I would talk about the relationship between governance and open source software in the context … Continue reading FOSS as Folk
I’ve touched down and started to settle into Tri-Met country not too long after returning from FOSS4G Korea. The public transit is great, the city vibrant with the warmth of a small town, and the energy of an enclave in a big city, and it’s also slightly surreal, now that I’m back where I am no longer, as Paul Ramsey put it, functionally illiterate. Functionally … Continue reading From Dobongsan to Mount Saint Helens — FOSS4Gs and OpenDroneMap
Fewer words, more pictures this time. On to Dobongsan Mountain. This time, I went through a different entrance just to the north and east of the previous entrance. Continue reading Bukhansan National Park, Seoul, Pt Two — on to Dobongsan Mountain
In my previous post on Bukhansan National Park, I had the blessings of a guide, ilJumun Jingwansa, who is a KNPS ranger. My second time in the National Park, I took a subway train by myself to explore. This was a quick hike to familiarize myself with getting to the mountain, rather than an in depth exploration. I took a train from my hotel in … Continue reading Bukhansan National Park, Seoul, Pt Two — off to the base of Dobongsan Mountain
For all the time I spent in the city of Seoul, I was able to make three trips into Bukhansan National Park which is partially inside the boundary of the city. It can be both a remote space, and a space overrun by visitors from the cities around. Seoul contains more the 10 million residents, and the metropolitan region is the third largest in the … Continue reading Bukhansan National Park, Seoul
for sweetness in `ls *sappy*`; do; It is bittersweet as I leave you, Korea. I did not intend to stay this long, so I do miss my family dearly. As my son started kindergarten, I flew to you, and you welcomed me. You astonished me with hospitality, humor, understanding, and the deep beauty of your people, your language, your Seoul, and your mountains. Thank you … Continue reading And then Steve gets all sentimental…
A classic and age old problem in GPS is collecting potentially wonderful data in the field, getting back the office, and realizing a lot of manual scrubbing, data massaging, and other such careful work will need to be done to make the GPS data useful and meaningful. This assumes we can even meaningfully correct it at all. This is true too (maybe especially) for GPS … Continue reading FOSS4G Korea 2014, poor GPS photos, and mapillary (part 2 of n)
