OpenDroneMap — Orthophotos and Textured Mesh

Good news to report, though I haven’t finished my own testing yet… but OpenDroneMap, which previously would just create point clouds from drone images, now also produces: Meshes! Textured meshes! Georeferenced textured meshes (if the exif data has geographic coordinates) Georeferenced orthophotos! (if the exif data has geographic coordinates) Now, I’d like those ifs to go away, but that requires a bit of thoughtful interface … Continue reading OpenDroneMap — Orthophotos and Textured Mesh

FOSS4G 2015 — reasons you should go

I know what you’re thinking. I spoke with you at FOSS4G 2014. You are a vendor who makes his or her money customizing free and open source software for geospatial, or maybe you also do core FOSS4G software development, and you are not sure of the benefits of sacrificing time and energy to go to FOSS4G 2015 in Seoul. Korea? I’m sure it’s really nice, … Continue reading FOSS4G 2015 — reasons you should go

OpenDroneMap — The MOVIE

Apparently travelling for 20 days straight back and forth through 3 time zones across 13 hours of time difference  makes me calmer, more rational, and a better presenter than normal. All 27 minutes and 35 seconds. And then don’t forget to check out the rest: http://vimeo.com/foss4g Continue reading OpenDroneMap — The MOVIE

OpenDroneMap and the art of sneakernet packet making

Current scene in the smathermather household — OpenDroneMap sneakernet packets being produced for training 53 people in OpenDroneMap on Monday. (Yes, I’m using rsync, not tar. Old dog. New tricks.) edit: let’s throw some code up there, ugly though it may be:   Continue reading OpenDroneMap and the art of sneakernet packet making

OpenDroneMap — Art and Science

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

Null Archipelago — Null Islands for All Coordinate Reference Systems — revision

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

Null Archipelago — Null Islands for All Coordinate Reference Systems

@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

FOSS as Folk

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

From Dobongsan to Mount Saint Helens — FOSS4Gs and OpenDroneMap

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

FOSS4G Korea 2014, poor GPS photos, and mapillary (part 2 of n)

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)
