@Memor-X on DLSite, some products got geoblocked in my country now, sad. Funnily/annoyingly, on some series, only partial works are geoblocked, thus the series number jumps and I can't have any clue what happens between them ☹
It is more of that this is a super general random chat room not specific to a SE site, even if you're invited to join to this chat from a specific SE site.
@JOSEEMILIOAGUILAR welcome. Based on my understanding, looks like this is related to GIS. We have a site specialized in that, and looks like they have some questions related to coordinate conversion on 'proj'. Feel free to browse the existing questions, you can also tailor the search keyword to suit your requirements. If you still can't find anything, feel free to ask a question. Hope it helps
@LawrenceChalmers if that's the case, you may want to ask a question by explaining your issue. Also, providing the link to that Q&A may also help readers know that you have checked it, and also mentioning that "nothing in notifications" may help in preventing the question to be a duplicate.
@albertoukostandili welcome, everything about API is on api.stackexchange.com/docs . If you need a key, then please read this FAQ (also, please use English so that everyone can participate)
@AbdurahimRaayyaa looks like the license to use the device has expired. I believe you should contact the provider of this device to consult about license renewal. Other than that, I'm afraid we can't help you because we're not a license provider here.
Not sure who or what is Swapna. If it's a person, I don't think you can get it here. If it's a company/corporate, have you searched their contact info?
