Usage statistics of OSM editors here …

Info about this page

Note that most plots on this page include at least one logarithmic scale. This may be unfamiliar to some readers (seeing usually linear scales).

Remark on updates. It will occasionally be updated, but I cannot promise to maintain regular intervals. If you think another update is past due, please remind me. See this page's history for the last update.

This page has been thoroughly redesigned in mid-2012. If you are looking for the older raw statistics, check the archive page.

Market share of various editors over time

The "market share" of an OSM editor can be defined using different weights: the number of changesets created, the number of its users, or the number of edits actually made, and various others (including combinations of the former). Each definition has its advantages and disadvantages, but each also tells something about how a given editor is (or was) used.

In the tables below, the market shares of various editors according to the aforementioned three definitions are presented, broken up into years. For the corresponding plots, the time resolution is six months.

Methodology

If you are not interested in technical details, feel free to skip this section.

All the information presented on this page is extracted from changesets-yymmdd.osm.bz2 files. An editor is identified by the created_by tag of each changeset. (This implies that 2009 data cover only the time following the startup of API 0.6, when changesets – and changeset metadata – were introduced, and that statistics for earlier years cannot be generated in this simple way.)

In all the tables, 2018 means "2018 so far". For obvious reasons, full-year statistics cannot yet be generated.

The tables and plots show, respectively, the number of changesets created using an editor (a simple counting exercise in processing the changesets file), the number of total edits made with it (computed by summing up the num_changes of each changeset), and the number of distinct user IDs (uids) seen in association with each editor. The latter is assumed to correspond to the number of actual users/mappers (though some may use more than one account, which is not considered here). The data are resolved by years for the tables and by half years for the plots. Market shares (as percentages) are calculated with respect to the overall sums.

In the "distinct uids" table, mappers editing with more than one editor will be counted once for each editor. This double-counting implies that the sum of all is not equal to the total number of mappers editing in a given period of time. The "market shares" in the corresponding plot are, however, calculated in relation to that number. Therefore, the market shares do not add up to one; instead, their interpretation is as follows: if an editor has, say, a market share of 0.5 in a given period of time, 50% of all mappers have used that particular editor at least once in that period - but some of them may have used other editors as well. For example, in the first half of 2012, Potlatch 2 and JOSM had respective market shares of roughly 85% and 36%, the sum of which already largely exceeds 100%.

The double-counting of users could in principle be remedied by "splitting" users according to some sort of weight, for example, the number of changesets created with each editor, but that would alter the definition and distort the distribution, diluting the desired information about the user basis. Therefore, such is not done here.

Observations

These are some conclusions to be drawn from the numbers below. The list is by no means exclusive.

  • It is obvious that according to the number of edits, JOSM has never been challenged as the number one editor (the only nominal exception in 2009 being a special case, when huge numbers of superfluous tags from the TIGER import were removed by woodpeck_fixbot using osmtools, and with changesets from before API 0.6 that can not be associated with any editor). JOSM's dominance is not so clear in terms of changesets created - this has to do with Potlatch 1 creating zillions of empty changesets in live editing mode, but also with the fact that Potlatch users tend to make smaller changesets on average, and iD users creating even smaller changesets than Potlatch 2 users.
  • Also, the common notion that the main online editors on the OSM website reach the largest number of users, is confirmed; with that role initially held by Potlatch 1, then Potlatch 2 and now shifting to iD. In fact, the number of actual edits made with Potlatch 1 has gradually decreased with increasing popularity of Potlatch 2, dropping to the permille level in 2012. However, the popularity of Potlatch 2 has so far been less affected by the introduction of iD than the popularity of Potlatch 1 when Potlatch 2 went live. As of early 2014, iD has twice the number of users Potlatch 2 has and created four times the number of changesets, but there are still more edits made with Potlatch 2 than with iD.
  • It turns out that Merkaartor, often regarded as one of the "big three" editors and seen as a serious competitor to JOSM, does not really fill that role. Merkaartor's market share has never exceeded 2 percent in terms of edits and 5 percent in terms of changesets; its user base has at no time been comparable to that of JOSM and has been continuously declining for years. This may be related to the editor's stalled development.
  • Most other editors have never reached percent-level market shares (the exceptions being import scripts, used by only few users but editing large amounts of data).
  • Recently, several smartphone applications have obtained a non-negligible audience (making very few actual edits per changesets, which of course reflects their goal of filling the niche for quickly editing, like entering the opening hours of some POI). These include Go Map!!, Vespucci, Pushpin, POI+, and the navigation tool OsmAnd.
  • Another mobile application takes a somewhat surprising position in the tables: MapStalt Mini by Microsoft. Quickly dumped onto the market in 2011 (not even able to write proper created_by tag, and unmaintained since the first release), MapStalt has for several years reached more users than most other mobile editors. The numbers of changesets and edits made by these users are, however, negligible; most users seem to only have tried the program once. But even the large number of (one-time) users is surprising, as the target system Windows Phone has never reached serious market shares, and one would hardly expect an above-average interest in a free/open/crowdsourced project from users of Microsoft's products.
  • JOSM's (relative) market share in terms of users has continually decreased over the past years (unlike its market shares by changesets and edits, which have remained roughly constant). The total number of all mappers has grown, but the number of JOSM users seems to have saturated. In other words: a growing percentage of users has been using exclusively one of the online editors and not been converted to JOSM users.
  • Considering the user statistics, one should keep in mind that these are fully unbiased counts. Every mapper who has made at least one changeset with an editor is counted as a user of that editor. Therefore the analysis distinguishes neither between one-time and regular mappers nor between main and secondary/auxiliary editors.

Tables and figures

These tables were generated automatically with wiki.pl from the changeset dump of 2.07.2018. The numbers for year 2018 are obviously not final.

OSM editor marketshares by distinct uids.svg

See comments above to understand why the market shares in this plot do not add up to one. (It's not a bug, it's a feature.)

See also this plot for the absolute numbers - the normalized plot above may be somewhat misleading if interpreted improperly.

OSM editor marketshares by edits.svg


More complex analyses

The tables and plots above present very simple and straightforward analyses, whose interpretation is unambiguous. On the other hand, especially the "number of users" analysis has a few weak points: For each editor, the table gives the number of users who have made at least one edit with it; there is neither any distinction between regular and one-time users nor between using some editor as one's primary tool and just trying it out once. For example, most users make their first edits using one of the online editors (Potlatch 1 in the old days, then Potlatch 2, nowadays mostly iD). They are all counted as e.g. "iD users" even if they quickly turn away from OSM or choose another editor for all of their later edits.

The plot below (made by User:Nop) constitutes an attempt to avoid these weaknesses and associate with each user a primary or preferred editor. The main differences of this analysis are:

  • Only the regularly used editors of each user are counted. Regular use means that an editor was used for at least 30% of the edits in that month.
  • The analysis is much finer. Data is examined by month (not cumulated over a whole year) so trends are more visible.
  • The plot is linear by market share of the major editors in percent and should be more easily comprehensible than logarithmic scales.

Editor profiles (2012)

In this section, a selection of editors are displayed at their position in a two-dimensional space spanned by various quantities which allow some characterisation of the editor. (The selection is more or less arbitrary. If your favourite editor is missing, please complain.) All figures are for edits in the year 2012 only.

Editor profiles users edits 2012.png

The first plot displays each editor by the number of its users and the total edits made using it, which may be interpreted as the editor's total impact on the OSM database. The distribution of editors across the plot is roughly diagonal: There is a mainstream region in the upper right, where editors have a large user basis and are used to create or modify large amounts of data: JOSM, Potlatch 2 and - to a lesser extent - Merkaartor and Potlatch 1. All other editors are used by relatively few mappers (down to just one), and consequently, relatively few edits are made with them. Only a few specialized tools for large-scale edits appear somewhat off-diagonal.

Editor profiles users avgEditsPerChangeset 2012.png

The second plot again has the number of each editor's users on the horizontal axis, but now the average size of each changeset is plotted on the vertical axis. This tells us something about how each editor is used - for editing only few objects, or for larger changesets. The number of edits in a changeset using one of the mainstream editors is of the order of 100. Surprisingly, the average JOSM changeset is only roughly a factor of 2 larger than the average Potlatch 2 changeset. Various other editors (often mobile applications) usually make only a few edits in each changeset. As expected, specialized tools for large-scale edits (used by only few mappers) generate large changesets. Of course, these are all just average values, which tell nothing about the distribution of changeset sizes. We will address that issue below and try to explore the distribution of changeset sizes.

Editor changeset size distribution.png

As mentioned, the average size of a changeset (i.e. the number of edits in it) provides only very little information about how an editor is used - some number appearing as an average value may result from very different distributions. To visualize the distribution of changeset sizes, quantiles are plotted for the mainstream editors in the plot to the right. Each box describes the changeset sizes which make up 50 %, 90 % etc. of all changesets created using a given editor (e.g. 50 % of all Potlatch 1 changesets contain 4 objects or less, 90 % contain no more than 58 objects). The 50 % quantile is the median; for both Potlatch versions, this is roughly identical to the average. For JOSM and Merkaartor, both measures differ significantly, hinting a larger tail of the changeset size distributions.

Note: I am aware that this plot badly needs some cosmetic improvements. Please be patient.

Changeset size histo 2012 100.png

The distribution of changeset sizes is also represented in this histogram, that is, a diagram showing how many changesets exist with 1-100 edits, 101-200 edits, and so on. (Empty changesets - 0 edits - are dropped here.) Clearly Potlatch 1 is hardly ever used for making more than a few edits, while the number of changesets made with Potlatch 2 forms a nearly constant fraction of the corresponding number of changesets made with JOSM for quite a large range of changeset sizes. Only for really large changesets with more than, say, 5000 edits, this fraction drops off significantly and goes to zero around 20 000 edits (see the corresponding histogram for the full range up to 50 000 edits). Another diagram for the low end (up to 200 edits) is also available.


Update discipline of JOSM users

Josm versions recent.svg

How regularly do JOSM users update their editor? This plot shows the JOSM versions in use in a given month, weighted by the number of changesets and clustered by the version number's leading digits. The majority of users clearly keeps their JOSM largely up-to-date, working with at least a recent "tested" release - commercial software manufacturers must envy the JOSM developers. The average version in use is roughly three months behind the current release; however, also very old versions are still being used by a small but nonvanishing and apparently die-hard number of mappers. Even the ancient release 1566 from May, 2009 is still seen occasionally.

There is also another plot which covers a longer term.
