The returned GeoPositionp[ from Locator has error in Latitude largely. See the following code. In this Poland map, Warsaw has {52.23,21.01} in latitude,longitude. Initialization of Locator to Warsaw did not work and there is 9.13 degree error in the latitude. It is huge error in location.

We're running a series of Data Science Friday webinars starting this coming Friday (Oct. 6, 2023) and running through the end of the month. This series will help you get a sense of how to work with data in Wolfram Language—importing, cleaning, visualizing and more with data spanning from traffic cameras to geological surveys to Mars and even other galaxies! ![enter image description here][1] The first webinar—again, that's this Friday, October 6 2023—will be lead by [@Tom Sherlock][at0] and will cover how to create the amazing images he shows [in this notebook][2] by using data from the James Webb Space Telescope. This webinar will primarily focus on image analysis and construction, with later webinars focusing on video creation, geographic visualization and even a combination of graph theory, image processing and machine learning. You can register for this series [**HERE**.][3] All sessions will start at noon Central US time. Remember that even if you can't make it to every Friday session, registration means that you'll get a link to the recordings delivered right to your inbox. We hope to see you there! I will update this post each week with information on that Friday's presentation; please feel free to post follow-up questions or comments here as well. ![enter image description here][4] [at0]: https://community.wolfram.com/web/sherlock [1]: https://community.wolfram.com//c/portal/getImageAttachment?filename=DS-Webinar-bigMarker-session-banner.png&userId=1711324 [2]: https://community.wolfram.com/groups/-/m/t/2997129 [3]: https://www.bigmarker.com/series/data-science-friday-2023/series_details?utm_bmcr_source=community [4]: https://community.wolfram.com//c/portal/getImageAttachment?filename=WolframUBanner.jpg&userId=1711324 Arben Kalziqi 2023-10-04T18:43:29Z https://community.wolfram.com/groups/-/m/t/3562391 &[Wolfram Notebook][1] [1]: https://www.wolframcloud.com/obj/d5e6a993-0d86-4c39-91b4-64b5395231f5 Robert Rimmer 2025-10-18T21:19:05Z https://community.wolfram.com/groups/-/m/t/3563534 In this preliminary post I introduce the idea of dynamical Transformation Functions, that is, the situation where the Transformation Matrices have functions rather than numbers as entries. I apply this specifically in the case of even (direct) isometries of real 3-space. I introduce DITF format which is independent of the construction of the transformation function. I give a geometrical interpretation which shows motion in space not only the position but also the orientation of the object. Several examples are given.

How can I export to svg or pdf a vector graphics of a geographic map of the Eiffel Tower, for example? GeoGraphics[Entity["Building", "EiffelTower::5h9w8"], GeoBackground -> "VectorClassic", GeoRange -> Quantity[400, "Meters"]] I right clicked on the output and clicked "Save Graphic as...", pdf format. I clicked the settings button and set "Use Highest Quality vector representation" as in the screenshot. Still, the pdf file is a raster graphics and not a vector graphics. Same when exporting to svg file. ![enter image description here][2] [1]: https://writings.stephenwolfram.com/2025/08/new-features-everywhere-launching-version-14-3-of-wolfram-language-mathematica/#maps-become-more-beautiful [2]: https://community.wolfram.com//c/portal/getImageAttachment?filename=ScreenShot2025-09-24at18.16.18.png&userId=1344988 Ehud Behar 2025-09-24T16:59:00Z https://community.wolfram.com/groups/-/m/t/3549441 A huge number of ingest site data repositories for Earth-orbiting data sensors store and publish their data in HDF file format. The HDF Group -- a spinoff from the UIUC-NCSA -- supports users of HDF datasets, including users of the NASA EOS. The HDF Group EOS support effort includes a large, on-line catalog of examples of accessing, processing, analyzing and visualizing the NASA EOS data files using the popularly used tools among Earth and Atmospheric scientists: NCL, IDL and MATLAB -- absent Mathematica. The attached Mathematica notebooks are attempts to replicate the HDF Group's hosted EOS examples in a similar style using Mathematica. - AIRS_L3_Temperature_MW_A_Lvls11.nb: Visualize a GESDISC_AIRS HDF-EOS2 Grid data file in Mathematica - Q20111212011151_L3m_MO_SCISM_V1_0_SSS_1deg_h5.nb: Visualization of a Level-3 gridded Aquarius simulation HDF5 dataset of Monthly (MO) Sea-Surface Salinity (SSS) from the NASA PO.DAAC (Physical Oceanography Distributed Active Archive Data Center) &[Wolfram Notebook][1] &[Wolfram Notebook][2] [1]: https://www.wolframcloud.com/obj/de5dcedb-f484-4586-a238-571876a9b23b [2]: https://www.wolframcloud.com/obj/d966b998-3937-4fa9-87fb-63554afcf9ad Stewart Dickson 2025-09-22T22:44:38Z
