New updates to "Latest Changes"

Posted by rene78 on 5 July 2022 in English (English). Last updated on 12 July 2022.

Multi devices “Latest changes” (https://rene78.github.io/latest-changes/) got a few improvements:

Tag comparison table

A table opens when clicking on any element. Updated key-value-pairs are highlighted in different colors (Green: Newly created, Yellow: Modified or Red: deleted). (similar to achavi). Tag comparison table

Download button

Button to download changesets instead of automatic download on pan and zoom. The long waiting times and frequent timeouts when querying overpass lead to a bad experience. With a button it is much better in my opinion. Download button

Vandalism Checker

Simple sanity checker for all the downloaded changesets. It adds up all elements and tags which have been added or deleted in the changeset. If the sum is below a certain treshold (currently -3) then a traffic light changes to red to alert the users of latest-changes about this changeset. Ideas on how to make this checker more powerful are welcome. Vandalism Checker

Examples

  • A user adds one new supermarket and deletes two roads: The sum would be -1. Vandalism checker stays green.
  • A user adds three key-value-pairs to a restaurant but deletes seven of a library. The sum would be -4. Vandalism checker turns red.

Small changes

A few other minor changes regarding the UI/UX. Check the GitHub pull request if you are interested

How to use

In a previous blog post I explained what this tool is about and how to use it. Please allow me to repost it here:

The purpose is to check recent OSM changes within a certain cartographic boundary, for example your home town. It is very simple and powerful:

  1. Open the Latest-Changes web app.
  2. Zoom to the area of interest
  3. Check and validate the changesets of the last 7 days (1 day, 3 days, 1 month).
  4. Bookmark the URL to regularly come back and monitor your area of interest.

Recently I have worked a bit on the web app “Latest Changes” (https://rene78.github.io/latest-changes/) in order to make it more mobile-friendly. Hope someone finds it useful.

Quick reminder to the ones of you, who don’t know the app yet. The purpose is to check recent OSM changes within a certain cartographic boundary, for example your home town. It is very simple and powerful:

  1. Open the Latest-Changes web app.

The power of OSM

Posted by rene78 on 24 May 2018 in English (English). Last updated on 12 June 2018.

I would like to recount an interesting encounter I had during a bike trip in Myanmar. In December 2016 I cycled from Yangon/Myanmar to Kuala Lumpur/Malaysia. Beforehand I was armchair mapping some tracks east of Bago, Myanmar in order to avoid the stinky and noisy main road and slightly short-cut the trip. Later I used OsmAnd+ to navigate those tracks.

It was precisely on these roads in the middle of nowhere - Google Maps is literally blank there - where I met a female solo bike traveller. She used Maps.me to navigate and was using ‘my’ roads to go into the opposite direction.

Quite entertaining to see the real world impact of all our mapping efforts.

Here is a picture of one of those newly mapped roads at a slightly different location.
