In last November 2017 there were around 700 educational institutions in OpenStreetMap, most of them in urban areas and nothing in rural areas, the information about educational institutions present in OpenStreetMap was incomplete and we really couldn’t know how many educational institutions exists in a place, or which places don’t have any schools.

Bearing in mind that many educational institutions do not exist in the map and with the purpose of having the complete information of all educational institutions of Peru in OpenStreetMap, knowing that this information will allow the government to make better decisions such as: Improve access to education, better educational politics as well as services and the quality of education in the country.

As part of a collective effort we made a coordination with the Ministry of Education, to be able to use the data of educational institutions that they manage through SIGMED’s portal and can use all data of schools and kindergartens for import into OpenStreetMap.

The import process was carried out following the import guidelines set in OpenStreetMap.

Process of School’s import

Step 1: Prerequisites

Before to start the import process of import, we identified the categories of the database of SIGMED, these categories includes categories such as Basic regular education(EBR), Basic alternative education(EBA), and productive technical education(ETP), for this process we just selected Basic Regular Education, this category includes 3 levels of education:

• Initial
• Primary
• Secondary

Step 2: Community Buy-in

We talked about the import schools, in the last SOTM, this event was made in last November in Lima.

Step 3: License approval

I recently discovered the Durham County Open Data site. Licensed under ODbL 1.0, it is a large collection of various data sources from election result data to bike racks. Some of the datasets are a few years old but most of it seems up-to-date.
Hopefully someone will be able to use this; enjoy!

A while ago I launched a few challenges on the new MapRoulette (new! you should check it out :)) that have to do with motorway exit information in the United States. Lots of exits around here do not have that information, encoded mainly in destination, destination:ref, destination:to and destination:name tags.

A destination being added based on a Mapillary image

These tags are helpful for navigation users, so they can match what they see on the sign to what they see on their app. Many navigation apps, including OsmAnd, MAPS.ME and Scout use these tags.

Obviously, this information cannot be added from aerial images, but now that there is plenty of street level images from OpenStreetCam / Mapillary to choose from, adding destination info as a non-local mapper becomes much easier. That’s why I created these challenges.

I’ve been enjoying the Notes features of OsmAnd, both for adding new ones and even more for finding nearby ones when I’m out and about. Every OSMer should tell all their friends to lodge notes! :-) I’ve been training everyone I can (two people so far; maybe I need more friends).

I also only recently noticed that people near where I live are actually leaving notes (they weren’t last time I looked a year or two ago.) Which is great, and I’m trying to fix them all. Many seem to come from MAPS.ME, and sometimes are in the wrong spots or are spurious (most commonly saying a thing is gone when it’s not). But more are useful than aren’t.

So I’ve added the RSS feed of notes for this area to my normal daily news aggregator, and hopefully will do a better job of keeping up to date with people’s corrections and spam.

Which is correct icon/point to describe fort in OSM? I couldn’t find it quickly :/

Some OSM users copy from Google Maps. Others go as far as to add the tag “source”=”Google Maps” to features. By using Overpass Turbo, I was able to find all objects with “source” = “Google” and “Source” = “Google Maps”. This returned 2734 different features attributed to Google Maps. Click either the link above or this one to see every single one. Perhaps we can fix or delete them all together.
Please note that Overpass Turbo may take a minute or two to search the entire globe for “source”=”Google Maps”.

I have at least started OSM wiki articles on the major cities of Turkmenistan, as follows:

*Ashgabat *Balkanabat *Dashoguz *Mary (Turkmenistan) *Turkmenabat *Turkmenbashy

The intent is to institutionalize all I have learned about mapping in Turkmenistan so far, before my tour of duty ends sometime this calendar year. If other mappers have suggestions for information to add to these articles, I am all ears.

I was going over unnamed ‘main’ roads in my area using this Overpass query in JOSM:

Most of the time I can use the TIGER overlay to add the missing names. Sometimes I stumble upon a way that should have been tagged as a roundabout or a link (and those usually do not have a name tag). There are some cases when a mapper has added a newly built road from survey or aerial images that does not appear on TIGER yet:

Hello, Community!

Last week I implemented history call to retrieve all old versions of an element, version call to retrieve a specific version of the element and added possibility to specify version number for element in multi fetch call, i.e.:

• GET /api/0.6/[node

  way

  relation]/#id/history

• GET /api/0.6/[node

  way

  relation]/#id/#version

• GET /api/0.6/[nodes

  ways

  relations]?#parameters (added optional version number)

Request examples:

• node 21265449 history
• way 4823378 history
• relation 123924 history
• node id=21265449 version=4
• way id=4823378 version=30
• relation id=123924 version=217
• nodes 26047550 version 28, 26047555 version 22
• ways 4903994, 4904157 version 7, 4904160 version 3
• relations 1148410 version 51, 1155947 version 6, 1155950

Unfortunately, current and history tables contains the same data, so currently it’s not possible to get all element’s history or some old version of element.

Next week I will implement relations for element and ways for node calls. So I will finish all read-only elements calls.

Week 3

The end to the academic year is always frantic, but working on iD has made the last two weeks more enjoyable. I’m continually impressed by the amount of time, effort, and collaboration that has gone into making OSM what it is today. I think I’ve only scratched the surface of the codebase.

Anyways, I am currently working on linking the notes API service to an SVG display layer. I’ve hit a few bumps, but I’ve found that most things are pretty straightforward. Notes are now successfully retrieved and parsed when the map is moved, and I’ve begun working on caching. Additionally, the map data UI now has a button for toggling map notes, and a placeholder button for adding notes (just like osm.org) has been added to the map-control list. It’s a placeholder because I haven’t quite finished adding the SVG to iD’s sprite sheet.

If you have any suggestions regarding notes or the notes UI, please reach out!

Cheers and happy almost summer (northern hemisphere),

It was my first time to leave my husband with our wildling 2-year old to fend for themselves for close to a week. Prior to leaving the house, I was wondering if it was right to go as I stacked up the fridge with food and the closet with clean clothes. I packed my luggage and my hesitation instantly turned to excitement. I’m sure I’ll learn a lot in Davao! (Translation: I can’t wait to be relieved from mom duties.)

I got this mapping stint from Erwin Olario. He didn’t have other options as nobody else was available from the OpenStreetMap Philippines local community. (No competition!) The invite came from Tambayan Center for Children’s Rights Inc., a non-profit, non-government organization based in Davao City. There were roughly 30 participants all between 11 and 18 years of age. Managing that number would be quite tough for a two-man team but with the strong assist from the very warm Tambayan staff, the whole four days were a breeze.

Here’s a short account of what transpired during the mapping workshop:

Day 1. Erwin started the day with a mapping exercise where he asked the children to draw a map for a friend who would be paying a visit. Then, Erwin and I took turns in rolling out a series of lecture-exercise planned for the entire workshop, specifically for the following tools: OpenStreetMap ID Editor, Field Papers, and MapContrib.

While looking at closed and abandoned railways in NSW I found someone had extended the closed Morpeth branch line to Seaham. No extension ever existed. There seems to have been a plan to run the North Coast line through Morpeth and Seaham, which was never adopted. See https://trove.nla.gov.au/newspaper/article/859401

I drove, or more precisely was driven, from Ashgabat to Dashoguz across the Karakum Desert on May 29, collecting Mapillary imagery (presently being uploaded, please be patient) and location data for POIs using Pocket Earth and MAPS.ME. We collected the numbers of the gas stations and the names of villages (i.e., navigation waypoints) en route plus locations of clinics and the district hospital in Ruhubelent. Met a Dutch tourist at the cafe near the Darwaza fire crater who was navigating with MAPS.ME and said it was extremely useful for getting around both Iran and Turkmenistan.

Once in Dashoguz we spent some time collecting more street names, some POIs, and correcting a few anomalies. If tourism ever is allowed to flourish in Turkmenistan, this will be a major route from points in Uzbekistan to Ashgabat.

You may notice in the ground-level imagery taken May 29 that the sky is white and visibility is limited to about a mile. This is because the area was subjected to a salt storm caused by winds kicking up salt from the desiccated seabed of the evaporating Aral Sea. This ecological disaster confronted us travelers in a particularly stark manner.

The weather is nice and I want to go out mapping a little later. It would be nice to have a file and map with things that I wanted to check. Today I will use Overpass Turbo, a great web interface to the Overpass API that gives you all the tools you need to create a quick Survey Kit that you can take with you: a map you can print, and a GPX file to put on your phone or GPS receiver.

Let’s say I am interested in businesses that have no opening hours so I can go and add those while I am out. This is a query that would give you exactly that. It is probably not complete and could maybe be simpler, but it is quick for small areas and it does what I need :)

I run this query on a commercial / retail area near my house:

I can then export this as a PNG map to print

Hello, Community!

I’m trying to implement Openstreetmap API using Go language.

I started to implement single element, multi element and full element fetch calls, i.e.:

• GET /api/0.6/[node

  way

  relation]/#id

• GET /api/0.6/[nodes

  ways

  relations]?#parameters

• GET /api/0.6/[way

  relation]/#id/full

To test that API works fine I used test suite. All routes are passed these tests. You can find detailed test reports here.

API demo is located here. Request examples:

• node 3789235498
• ways 19925906, 20300927 and 20869196
• full relation 19788

Database contains data only in bbox=27.61649608612061,53.85379229563698,27.671985626220707,53.886459293813054 and data can be out of date.
