Updates and Payment Information – EWGLA 2025
by Luisa Isabel Martinez Merino 07 May '25

07 May '25

Dear EWGLA Participants, We are pleased to inform you that a preliminary schedule, including key dates and times, is now available on the EWGLA 2025 website. Additionally, we would like to share important information for those who have not yet completed their registration. An online card payment option (TPV) is now available, specifically for participants who may incur extra bank fees when paying via traditional bank transfer. You can find detailed instructions on how to proceed with this payment method at: https://ewgla2025.uca.es/registration/ [ https://ewgla2025.uca.es/registration/ ]. Please note that this option is intended only for those affected by additional bank charges. If this does not apply to you, we kindly ask that you continue using the standard bank transfer method. Finally, a friendly reminder that the early registration deadline is May 15. We hope this facilitates your registration process, and we look forward to welcoming you in September. Best regards, The EWGLA 2025 Organizing Team

Location related references May 2025 collection
by Frank Plastria 05 May '25

05 May '25

Dear fellow locater, Here is the May 2025 collection: 81 references about or related to location science, almost half brand new from this year, the other almost half from2020, as well as a few missing items from my previous collections for the years in between. There are still many hundreds to come before filling the gap I left since my retirement in 2013, so this monthly column started up again in July 2023 will be continued for quite a while (I hope). Working backwards at this pace the backlog might take another two or three years at least. And new ones keep flowing in at an incredible rate ... Cheers Frank Prof. Em.

EWGLA2025 – Registration Payment Options and Deadline Extension
by Luisa Isabel Martinez Merino 29 Apr '25

29 Apr '25

Dear EWGLA Participants, This message is intended for those who have not yet completed their registration. In response to several requests, we are working with our university to enable payment via TPV (online card payment) for those who may face additional bank fees when paying by traditional transfer. Unfortunately, the process is taking longer than anticipated, and we have not yet received final confirmation that this option will be available. Therefore, we are extending the early registration deadline to 15 May. We will keep you informed and share any updates as soon as possible. Best regards, UCA Luisa Isabel Martinez Merino Departamento de Estadística e Investigación Operativa Profesora Ayudante Doctora Universidad de Cádiz luisa.martinez(a)uca.es [ mailto:luisa.martinez@uca.es ]
