The geoglyph of a shark is a 75m long x 35m wide and is an oriented to head southwest (head) and northeast (tail) on relatively flat grade. It seems to be pointed towards a series of multiple geoglyphs just 200m to the southwest. To the northeast, a very interesting Mandela Square (also, not a perfect square) is located just around 700m away.
it is a side view of the shark and there is no other indications of other nearby geoglyphs immediately associated to this graphic.

The geoglyph of a coiled snake 100m wide x 125m long (including the coil) and oriented in a northeast (head) to southwest (coil including tail) direction is adjacent (approx. 5m) to some Nazca lines and similar geometrical shapes. The coil followed by a straight body, eye, wide open mouth and forked tongue makes the snake look like its hissing as a warning. The snake appears to sit on a trapezoid shaped feature. It is possible that the snake is inside a box or container. It is difficult to tell more about what this snake is doing.

The 30m wide x 50m long geoglyph of a flying feather crane drawn on a relatively flat surface appears to be oriented northeast (head) and southwest (tail) Its smallish head with eye, Long beak, long neck, body and two wings seems to be carrying some kind of food or nesting material. There also. seems to be a long geoglyph line behind it, possibly showing the birds curving flight path?

TL;DR I wrote new console app that takes GTFS as an input and tells you exact changes you need to do in OSM to make it as close to GTFS as possible. Head to source to start using it.

Try it out on your GTFS and let me know how it went! I am open to suggestions, new ideas and new checks!

Description

Purpose of this tool is to help find errors and differences between GTFS and OSM data. It will also help point to errors in PTv2 routes in OSM. It covers wide range of errors, tag checks, geometry checks… (when I say “wide”, I really mean it! - check README.md to keep me honest, I am really proud what you can check today).

Once you import data in OSM (or when new version of GTFS data is released), you can use this tool to check if all data from GTFS is imported in OSM correctly and what are differences.

Tool is heavily relying on PTv2 spec and do not try to deviate from it. One would might say it is “opinionated”:)

This tool is not general-purpose PTv2 quality assurance tool, even though it points to a lot of PTv2 errors in OSM. It is handy if you are OK with console output and quick iterations as you can grep it, cron it, sed it as you like. Check this wiki for other great tools.

Why new tool

The British Cartographic society has published a short free book about Cartography. It gives and overview of the purpose of cartography and it’s main principles. Quick but very worth read for all mappers.

You can find it here:

Cominciare

Vorrei cominciare a tracciare tutti sentieri boschivi, tratturi, strade bianche della Basilicata. Dal primo gennaio ho messo su un sito Sentieri Lucani dove raccoglierò tutto ciò che riguarda il progetto. Sarebbe una sorta di Mapathon ma, per adesso, sono solo. E non c’è nessun “evento” correlato. Piuttosto sarebbe una cosa lenta e continuativa. Vorrei fare in modo che tutti le tratte del “Sentiero Lucano” e “Sentiero 2 mari” siano presenti su OSM. Ecco il link al sito della regione

Prima mossa

Ho cominciato a mappare i sentieri di Bosco Magnano (anche quelli non facenti parte dei tracciati della regione). Alcuni sono pieni di rovi (e ho deciso di non aggiungerli). Altri, anche se difficoltosi, si riescono ad attraversa. Cerco di usare tutti i tag per definire le strade.

[In continuation of „Sidewalks by length“ blog post.] As requested there, below chart for all of the world. Also chart for the US East coast, where, by their length, a whopping quarter of all of the worlds footway=sidewalk are located. 60% of the whole earth set is in the US alone (excluding Hawaii and Alaska.) As clearly can be seen, in the US this method trumps the other one, of mapping sidewalks as a property of the streets, they are part of.

For the the world outside of the US, the ratio is not as decisive, but rather more on par. Mapping sidewalks as footways seems, to use a highbrow term in the sense it is sanctioned by the Oxford English Dictionary, prevalent in US mapping.

For a popularity contest, the total alone is sufficient to declare a winner. To determine popularity in this contest though, where every voter has an unlimited number of votes, the number of voters is of interest too, and also the distribution in the number of votes spent per voter.

This requires a bit of hand-waving, errm, a little overpass-turbo experiment, first zoom out to all of the world, sorry, that probably will timeout the query, so settle in on the area from Richmond to Boston - https://overpass-turbo.eu/s/12M7

OHSOME counts 20,000 km in cumulated length, overpass returns 160,000 objects by 2,460 users, which might not be too far off (average length 125m). Paste the data in a spreadsheet and do a bit of more hand-waving - 50% of the data was last modified by 1.6% of the users. Not quite a few have spent quite a lot of votes, so to say. Sidewalk mapping seems to be popular with a select few, most prolific individuals. In statistics speak: The mean being ten times the median being six times the mode, it’s a heavily skewed distribution, where practically all of the contributions come from the outliers.

I am mapping because I want to map the world better. For a better experience.

better map - better experience

I want to add veryfied information and help every user using OSM or a connected application.

I’m running for reelection to the OpenStreetMap U.S. board of directors.

For those who don’t know me, I’ve been contributing to the OpenStreetMap project as a volunteer since April 2008, mostly as a mapper and an advocate for the project. I love pondering tagging dilemmas and seeding the map with a level of detail that pleasantly surprises users and gets them off the sidelines. (As for my day job, I’m proud that the iOS software I write at Mapbox is powered by OSM data, but I’m my own board member and mapper.)

In my position statement last year, I wrote about the need to build bridges. Since then, OSMUS and the OSMF achieved normalized relations via a local chapter agreement. Without the distraction of local chapter negotiations, we can look forward to partnering with OSMF in forging less obvious relationships that bring more participants into the OSM project.

I had looked forward to meeting many of you at this year’s State of the Map U.S. conference in Tucson. Instead, we responded to the upheaval of 2020 by organizing the Connect conference and continuing a series of Virtual Mappy Hours that ranged from imports to issues of social justice – all at a safe distance online. I hope you found these events to be as worthwhile (and as much of an escape) as I did.

As a board member, I arguably had the least hands-on role in each of these team efforts. My job has been to connect them to the bigger long-term picture. It’s important for me to give our executive director, Maggie, the room to get the implementation details right but also be available for a gut check or proofread as needed.

The pandemic changed the OSM-PH community plans for the year in 2020. In person meetups became online and we had to adjust our big plans for this new approach. I collected the publication materials we posted in our social media account to get a broad sense of what we did last year.

The montage above is a small collection of them. Some highlights.

A geoglyph 50m wide x 100m long, oriented northwest (head) and southeast (feet) on flat land shows a woman sauntering quickly in a long robe, and head scarf in a westerly direction while carrying some kind of moderately sized object at waist side. The image is created as a side view thus allows the viewer to see her face in profile, one hand, two feet, and her body in motion. She is drawn on some relatively flat land, and there are other geoglyphs nearby.

Geoglyph of a campfire (25m x 20m). At first it looks like a bunch of random lines going nowhere and coming from nowhere, but they were connected and only after establishing the location of the Man with the decapitated head, are you able to conjecture its meaning. This geoglyph seems to represent a hot flame campfire from a side view. This seems to be more than a zig zag trail we see typified everywhere making it appear as if its a side view of a campfire.

This geoglyph appearing like a massive landing strip and bisected by a channel scar 225m long x 75m wide on moderately sloped land had to be built as two massive parts to appear connected like one. There are five major lines with a center line appearing like a landing strip oriented north to south. There are many other lines in this immediate area and there is little evidence what this is for. The channel scar that cuts this particular geoglyph in half appears to have been there before the geoglyph was created. This assertion seeming older than the geoglyph is because the lines from one side of the channel scar are not razor sharp and have some “off alignment” associated to it..

A geoglyph of a salmon 50m wide x 110m long oriented northwest (head) and southeast (tail) has its belly to the north. This single fish appears as a side view on moderately sloped terrain, with one eye, one gill, fins, and tail all splayed out on a hill. The nose of the fish in terms of the terrain is pointing downward and flipped in a action being upside-down, suggesting it is in the spawning process to lay eggs upstream. The fish is relatively well made and the artist had some knowledge of anatomy or at very least, a good eye with technical skills. .

Yesterday was my first day, I think I found a new hobby. This is very enjoyable and I feel accomplished when I make a difference. GIS is a great technology.

I first contributed to OpenStreetMap in 2014 in a small town in rural Italy where I briefly lived/worked after finding it wasn’t mapped on any platform. After seeing the small town appear on the map I was hooked. Since 2017, I have led a monthly OpenStreetMap meetup, MapABQ, in Albuquerque, New Mexico focused on contributing to OpenStreetMap in New Mexico, an often overlooked area in the United States. Since the group’s inception we’ve engaged with existing mappers around New Mexico and recruited a number of new mappers, while greatly increasing data coverage in New Mexico on OpenStreetMap. Professionally I am a software engineer focusing on geospatial data. I’ve developed tools around OpenStreetMap with Humanitarian OpenStreetMap Team (HOT) and use OpenStreetMap data in my current role with SharedStreets.

I am running for the OpenStreetMap US board of directors for 2021-2022 and I have the following priorities:

Support of local communities

I believe OpenStreetMap thrives best in local communities and supporting the growth and sustainability of local groups is mutually beneficial to OpenStreetMap US. Scholarships to State of the Map US and microgrants for specific projects are great ways to increase participation and engagement from often overlooked regions in the US.

Sustainability of the organization

To ensure the success of the executive director role additional paid positions within OpenStreetMap US may assist in the administration and operations of the organization. Paid roles require consistent funding and long term planning to be fully effective. I seek to promote diverse funding, increase membership, and further cultivate existing donors to ensure financial sustainability.

Increased engagement
