Achavi Helper Website

Posted by SafwatHalaby on 14 November 2017 in English (English)

Achavi's main use is analyzing changes in an area between two time periods, but it can also analyze changests.

However, for some reason, that feature is not exposed via a graphical UI and requires tinkering with bookmarklets or urls. The Achavi "about" page claims dragging and dropping a changeset URL would analyze it, but this does not seem to work.

I created a simple helper site. Type a changeset ID or URL, and it will be analyzed with Achavi.

You can use https://overpass-api.de/achavi/?changeset=xxx to analyse a changeset. For the bookmarklet - you don't drag and drop a changeset url, you just click on the bookmark when on a changeset page, which then opens up the first url I posted.

Hi,

Clicking "help" in Achavi reveals the following: "A single changeset can be visualized by drag & drop of a changeset URL or using a bookmarklet". Drag and drop does not work. and I wanted something a non tech-savvy user could and which is convenient on mobile. This rules out link editing or bookmarklets.

Drag & drop of a changeset URL works for me with Firefox and Chrome on Ubuntu (but might not work this way on mobile).

Given achavi already open in a separate window and a link to an osm.org changeset, e.g. https://www.openstreetmap.org/changeset/53657054:

It might be useful to also add OSMCha and changeset-map to your page:
