Few days ago I started playing with OSM-Carto leisure=park colour in Photoshop, because I find it too “crappy” for modern design standards and too blueish. Then I changed @leirure-fill colour to lighter, matching future amenity-fill colour (see: https://github.com/gravitystorm/openstreetmap-carto/pull/3412). I think those are 3 (@amenity-fill, leisure=park, @leisure-fill) areas that should be made more prominent as they are almost always smaller and more interesting city part than eg. landuse=residential or landuse=industrial. I also added possible new colours for landuse=allotments (see: https://github.com/gravitystorm/openstreetmap-carto/issues/3411) and natural=scrub (see:https://github.com/gravitystorm/openstreetmap-carto/issues/2098)

There are many voices that current version of OSM-Carto is generally too pale, so making some elements brighter seems awaited. After changing colours of areas mentioned above, roads became less prominent. There was also some voices on Github, that we should make them brighter, so I tried also with it.

Colours used:

  • amenity-fill: ffffe5

  • park: 9df29d

  • leisure-fill: f2fff2
  • secondary road: f2e76d
  • primary road: f2c66d
  • trunk: f2996d
  • motorway: f2786d

Some before/ after screens (please notice that they are just Photoshop mock-ups to show the idea, so there are small errors like a little bit invalid outlines around footways in parks)

I’m happy to announce the RoboSat v1.1.0 release — our open source end-to-end pipeline for feature extraction from aerial and satellite imagery.

This release is powered by major community contributions from features like fine-tuning trained models, to training and prediction speedups, and bug fixes! Thank you to our contributors!

Here is an overview of what you will find in the v1.1.0 release

You can find automatically built Docker images at https://hub.docker.com/r/mapbox/robosat/


For our next release we already have a couple amazing community contributions

Here’s why you should be excited for the Lovasz loss: the following shows a preview

I recently began contributing images via OSC. I’m using the app from Google Play updated on 21/8-18. Here is a sample of the direction being the same on all photos: http://openstreetcam.org/details/1292987/0/edit-osm (press iD to see the layer with directions shown).

The OSC plugin (v164) in JOSM (v14272) does not show direction, only blue dots.

Also my tracks have not yet been processed for signs or other data and no special layer with this information is avaliable to my knowledge.

Is Mapillary prefered over OSC because it includes directions of photos & this layer?

Monday my schedule was inexplicably scrapped. An all-day conference failed to materialize. We went for a drive, a day trip first to Nohur, where Alexander the Great left behind a garrison some thousands of years ago, and where some inhabitants to this day have green eyes bequeathed by their Greek ancestors, then onward, to the Sumbar River valley. I identified two mysterious villages that appear on imagery but till then in OSM had no names: Kürüždeý and Duzlydepe. We drove over dirt and gravel mountain roads, down steep valleys, and confirmed the tracks of some roads, including one that follows a riverbed for a little way (the water was not deep this time of year).

I also found that a road someone drew “speculatively” (his word) on the map about four years ago doesn’t really exist, at least not where it was drawn. Upon return I adjusted it to the GPS trace as far as we went, but deleted what I could not confirm. Locals said the road goes no farther any more due to mud- and rock slides, so that part of the OSM map is more accurate now.

Mapillary imagery is being uploaded as I type this. The scenery was nice, but in springtime it must be spectacular. I will have to go back when the grass is green and the flowers are blooming.

We’re coming to the end of the UK quarterly mapping project on footpaths.

The designation=public_footpath edit tracker

…is running for just 5 more days. So last chance to get on there UK folks! This is all about our UK system of legally designated “public rights of way”, so if you’re elsewhere in the world you may stop reading now.

You may notice that I only just became a new starter on there myself! This is partly because I found it a bit tricky to understand what we’re supposed to do, but I finally sat down and figured it out at the weekend. Sorry it took me so long, but better late than never, here’s a few quick pointers:

Use Rob Whitaker’s PRoW data comparison tool. There’s a list of regions where he’s managed to get PRoW data.

Drill down to regions -> districts -> borough. You might pick where you live, but not everywhere’s on there. Failing that, try to find somewhere you know. Failing that, I guess it doesn’t matter where you pick.

Now you’ll see a map with lines. Here’s a bit of Watford

Go Map!! is an OSM editor I maintain for use on iPhone and iPad, available from the App Store.

Version 1.6 was released last week, with the primary improvement being support for multipolygon relations, and much improved protection against accidental damage to relations of all types.

More importantly, I’ve published the source code on GitHub if you’d like to contribute or use the code in your own project: https://github.com/bryceco/GoMap Building the source requires a Mac and Xcode. Contributing code requires fluency in Objective-C. It is released under the ISC license, the same as iD.

If you are a frequent user of Go Map!! and wish to be a beta tester please send me an email using the app’s “Bug Reports and Suggestions” button.

Finally, here’s a short video showing basic use of the app: https://youtu.be/GUWg4d-jt5o

Yesterday 9/23/18 was the “Typhoon Ompong Mapathon” at Co. Lab Pasig which the goal is to map affected areas by the recent super typhoon Ompong, joining with me in this mapping session is Ron. Woke up that morning and went to the set meeting place that Ron and I talked about, although Ron lives at Pasig I was the one to arrive first at the meeting place and waited at a nearby mcdonalds which was around 30 mins., he arrived late because there was traffic at his place which was unusual since its a Sunday, we arrived 10:30 (set time was 9:00 AM) cause we got lost and with the google map we were following is slightly inaccurate but nonetheless we still got there sweating haha (hot day). I like the chill vibe that Co. Lab offers as a workplace which you can rent, kinda like what function rooms do. I was surprised that the people there got the invitation randomly which I thought it is composed of select students from other schools although there were some but it mostly composed of adults wanting to learn and contribute. I enjoyed it, talked to the people at our side of the table, one is also a freshmen and his course is related to geography and he is new to osm, Ron taught him some basic stuff and was good to go, while that was happening I got to map a lot of buildings (around 3000 plus nodes) given by the instruction of the hot tasking manager, moved up through the rankings in the leader board which I was very contended. We ended the session around 1:20 PM and took a group photo, bid farewell to some people and headed home.

Based on my meetings with the minister of motor roads and the head of the Turkmen Motor Roads State Concern “Türkmenawtoýollary” plus interviews of local drivers, hunters, fishermen, and others here, I have identified many of the segments of the national highway system in Turkmenistan and as of this evening have mapped all but one of them. The P-8 “highway”, really a dirt road, needs GPS traces to be collected before it can be properly identified, and that is problematic since it is in a border zone more or less off-limits to foreigners. I know people who have driven that route but they are unable to verify its route from satellite imagery.

We are still missing the route number for the highway from Kerki to Ymamnazar. It overlaps with the P-36 part of the way, but not all of the way.

There may be other “national highway” routes out there and I’ll continue to keep my eyes peeled for them.

Some local mappers have taken it upon themselves to add street names in some towns in Turkmenistan following my master classes and presentations on mapping. That is gratifying. New POIs are popping up, as well. If we could only find all the gas stations!

Dear all,

Today, v4.15.0 of the OpenStreetMap Carto stylesheet (the default stylesheet on the OSM website) has been released. Once changes are deployed on the openstreetmap.org it will take couple of days before all tiles show the new rendering.

Changes include

  • Changing gastronomy objects color to orange (affects restaurant, fast_food, ice_cream, food_court, bar, cafe, nightclub, pub and biergarten)
  • Changing farmland and societal amenities (like school, hospital etc.) colors to fit better into the overall color systematic
  • Adding rendering for man_made=wastewater_plant and man_made=water_works
  • Adding icon for man_made=storage_tank and man_made=silo
  • Adding icon for amenity=bicycle_repair_station
  • Adding icon for leisure=amusement_arcade
  • Adding icon for shop=bookmaker
  • Adding icon for shop=trade and shop=wholesale
  • Adding rendering for attraction=water_slide
  • Rendering most of the road links thinner (affects trunk_link, primary_link, secondary_link)
  • Moving manors to z16+
  • Fixing missing country labels on z4 (affects Canada, Russia and Greenland)
  • Small code and icon fixes

Thanks to all the contributors for this release.

For a full list of commits, see https://github.com/gravitystorm/openstreetmap-carto/compare/v4.14.0…v4.15.0

As always, we welcome any bug reports at https://github.com/gravitystorm/openstreetmap-carto/issues

September 20, 2018. Another day for us mappers to help the world.

It’s our 8th session this time in PUP San Juan. From the beginning, we have accomplished so many things. But most of it was today, our chance to help in the Ompongph Mapping.

As we start today, we had a little problem with our equipment to be used. We finalized it first before we start. While waiting for the group assigned, our mentor which is Sir Erwin Olario, mentioned the Mapathon that will be held this coming Sunday. It will be about the mapping in some afffected areas made by the Typhoon Ompong in the Philippines. Some of us can be able to go but some are not.

Our objective for this session was to help in mapping the affected areas from the Typhoon Ompong. Little we know, it will be a “Typhoon Ompong PUPSJ Mini-mapathon” for today. So far, this is our first mini-mapathon because it is really urgent this time. We have 3 tasks to do from the HotOSM and we must all be able to map and validate some works. Our class was divided into two. The other half were the ones who needed to accomplish some missed tasks from the last session, while the other one were the ones who will help on the mapping from HotOSM. I was part of the second half who will just map on some affected areas in the Philippines.

As we work on HotOSM, I can see that Typhoon Ompong really hit a large area in the Northern part of the Philippines. There were large tasks to do and we needed them to split for other mappers can help us at the same time. I worked along Cagayan where buildings are needed. As a mapper this time, we used JOSM as our editor for this task. I’m not really used to JOSM but as needed, I explored it a lot this time to make my mapping session productive. I mapped some buildings on the selected task and I can really say that JOSM is more helpful and fast at the same time unlike any other editors we can use. The buildings I added were many but I didn’t accomplished the whole task because of the limited time we have.

By now many folks have seen Geoff Boeing’s really neat charts of street orientation that highlight how “gridded” (or not) the layout of city streets are:

Since Geoff was kind enough to provide a full open-source tool-chain, I decided to tweak it to chart the orientations of the streets of some cities and villages in my home state of Vermont:

Street orientations of Vermont

Unfortunately, until I get around to importing Vermont town boundaries, not all towns will be super easy to include in this analysis.

Ethiopia’s main economic activity is Agriculture. Smallholders in Ethiopia farm around 37% of the lands and the rest 8% goes to the large-scale commercial farms. Large-scale commercial farms produce crops such as rice, maize, coffee, tea, cotton, pulse, rubber, and palm oil.

Invest in agriculture is the most important and most effective strategy for poverty reduction in rural areas. As part of Ethiopia’s development strategy, the Ethiopia government has set out to attract more foreign investment in large-scale commercial agriculture as outlined in this policy. image

India has a road network of over 56,03,293 kilometres(56 lakhs kilometres) as on 31 March 2016, the second largest road network in the world. Openstreetmap has about 15 lakhs of road length mapped in India.

What percentage of the population can reach the nearest hospital in 20 minutes?

What percentage of the population can be rescued by fire and rescue department in case of emergency in 30 minutes ?

We should place our hospitals and fire and rescue stations with the support of spatial data analysis.

For that, we need data, Open Data !!!

Total Navigable Roads in India

Data from https://metrics.improveosm.org/

  • Q3 2016 - 11,71,820 Kms
  • Q3 2017 - 13,02,207 Kms
  • Q3 2018 - 15,05,239 Kms

Last one year OSM has mapped about 2,03,032 Kms (from Q3 2017 to Q3 2018). Previous one year OSM has mapped about 1,30,387 Kms (from Q3 2016 to Q3 2017).

Defining reversion

Through a healthy community and map-gardening many of the critical issues get noticed and acted upon immediately. A revert is absolute and removes changes indefinitely from the map. Repairs are more manual, often done with a mix of reversion and manual fixes, which are harder to track. osm-revert-changesets npm module is aimed at tracking absolute reverts and works well at 1:1 (changeset to changeset) reverts.

Reversion rules used

Currently, the module uses a starting set of 2 rules to identify reverted changesets.

  • Deletions of created features
    • If a feature gets deleted at 2nd version. The edit that created the feature at 1st version is reverted.
  • Feature state is reset
    • If Nth version of a feature is reset to N-2th version of a feature, then modifications that were done at N-1th, were reverted.

Usage

npm install osm-revert-changesets

const revertChangesets = require('osm-revert-changesets'); revertChangesets('62632427').then((list) => console.log(list));

Log [ '62629726' ]

This is the input used - DWG repair changeset osm.org/changeset/62632427. And this is the changeset that got reverted osm.org/changeset/62629726.
