Hi, thank you for your coordinate adjustments on the french WP: [1], following your update of the above file. I don't think the image change was due to the path of Ciara, as it is unchanged between prior and actual image. Moreover, position difference between the two versions of the image on the Y axis is very slight (and an even lower difference at lower zoom factor). => I don't know where the problem comes from. Nota: path for ex-Lorenzo is shorter in the last update. Is it an intent? Yours, En rouge (talk) 18:44, 14 February 2020 (UTC)[reply]

No problem, happy to help. Ciara did actually change the Y (read: latitude) value significantly every time it went into the higher latitudes on both its own track and the combined one. In fact, I had to cut off parts of Antarctica on Ciara's own track with the last two updates, because the tool I'm using (as well as pretty much everyone creating track maps) isn't smart enough to know that Antarctica isn't the North Pole (note the height of the image changed ever so slightly in Ciara's track upload history).
The path for Lorenzo is intentionally made shorter to be in accordance with its best track from NHC - see Lorenzo's track file for the link to that best track file (and the upload warring about whether or not to show the category 5 data point). As far as I know, best track is preferred over the 'live' co-ordinates given by NHC forecasters in their advisories, thus to me it seemed best to follow that to ensure at least some kind of consistency across pages and within the pages the combined track map is used on. The consequence of using the best track track is that the Y values shifted again. At that point the numbers on your map were literally all over the place, in that some didn't match their respective storm but another one tracking a tad higher.

@DarkShadowTNT: OK, thanks for all! But: I still not agree with your proposition regarding the image shift value on the Y-axis!
Therefore I uploaded test images to compare your uploads, the files on 2020-02-11 and on 2020-02-14. I made overlays of these 2 pictures:
  • the two images are directly superimposed, at 50%/50% values, see [2].
The overlay can bee seen on the ex-Lorenzo path, Dennis and Ines pathes (faded appearance).
  • the two images, at 50%/50% values, with offset of the image 2020-02-14 along the Y axis, 19 pixels upwards, see [[3].
2020-02-14 image is colored in red
2020-02-11 image is colored in green
Thus, the image shift is *only* 19 pixels on the Y-axis!
  • same as above, with images downscaled at width 960 pixels (960 is the width of the image in the french page), see[4].
The Y offset of the image is now around 4 ~ 5 pixels!
This cannot explain your edited values in the french page (modifications of coordinates: about values of 20 vertically) note: the value unit is rather the same as the number of pixels (values are from 0 to 900, pixels are from 0 to 960).En rouge (talk) 19:04, 16 February 2020 (UTC)[reply]

Tracks[edit]

Hello, need track maps for the 2022–23 European windstorm season pls El Cubano 153 (talk) 19:43, 28 October 2022 (UTC)[reply]

Need the WTOC track map generator, no known-me see the app, pls need the tracks, i'am edit me for you need the tracks El Cubano 153 (talk) 19:44, 28 October 2022 (UTC)[reply]

Instructions for using the track generator are located on Wikipedia:WikiProject Tropical cyclones/Tracks, if that helps. I haven't used it for quite some time and I'm currently not really into it either. DarkShadowTNT (talk) 17:54, 29 October 2022 (UTC)[reply]

Dear Wikimedian,

Wikimedia Commons is happy to announce that the 2022 Picture of the Year competition is now open. This year will be the seventeenth edition of the annual Wikimedia Commons photo competition, which recognizes exceptional contributions by users on Wikimedia Commons. Wikimedia users are invited to vote for their favorite images featured on Commons during the last year (2022) to produce a single Picture of the Year.

Hundreds of images that have been rated Featured Pictures by the international Wikimedia Commons community in the past year are all entered in this competition. These images include professional animal and plant shots, breathtaking panoramas and skylines, restorations of historical images, photographs portraying the world's best architecture, impressive human portraits, and so much more.

For your convenience, we have sorted the images into topical categories. Two rounds of voting will be held: In the first round, you may vote for as many images as you like. The top 30 overall and the two most popular images in each category will continue to the final. In the final round, you may vote for just three images to become the Picture of the Year.

Round 1 will end on UTC.

Click here to vote now!

Thanks,
the Wikimedia Commons Picture of the Year committee
