Hey, who wants to go to the #cinema in #Hanover? If you think that sounds like a good idea, don’t use a #map app that automatically scrapes #Wikipedia for locations to find one – unless you’re fine with watching a film on #AppleTV instead. Because where once was the historic cinema Palast Theater is now an #AppleStore.

(The cinema shut down before #OpenStreetMap even existed, so don’t blame them!)

I have a question about mapping tools that can help with local activism/organizing/campaigns.

I am currently using Google Maps to plot individuals at various addresses. (Easy to import data to the map, I can share this with others, etc.)

But there is a problem. If there are multiple individuals with the same address, Google Maps only puts one pin at a given address...and no additional symbology/color to show you that more than one pin is plotted...even if you hover over it or click on it...only the top pin is shown.

What other mapping tools (that I can easily share with others) can properly display multiple pins at a given address?

(This question also opens the door to other features...can field operatives make updates in real time and share to a central data source/server?...and more and more.)

As always, for grass-roots stuff...free is best, lowest cost is next best.

Feel free to boost.

Thanks in advance!

I seem remember a #Mapping (Software Development) related #Event in Austria. I believe it was an #OpenSpace. I missed it several years and now can't remember how it was called.

Can someone tell me the name?

Found: It's the @comocamp
(thanks to @kober for the pointer)

Map Area Showcase

Share a screenshot of your favorite spot on the map, along with its coordinates! An intricate city, a hidden natural wonder, or something totally unique, tell us what makes this place special! Let's see your top picks!

I have a few photo books to make, of course with maps. Do people watch live streams of that sort of thing?

#UNMappers x #FAO mapping updates

HUGE thank you to our volunteers and top contributors! A record of 800+ tasks mapped in 2weeks

Nous réfléchissons depuis quelques mois à mettre en images et en scène une petite histoire radicalement humaniste. Quoi de mieux pour élaborer quelques recettes lumineuses qu'une biscuiterie souterraine ?

It doesn't really show up on the scan but I love that this sender used glitter to illustrate their dream! Lovely.

Hey #geo nerds!

I haven’t made a web #map in a while. What’s the current tool for making a super simple web slippy tile map with pins dropped into it? Ideally free (for a low traffic website).

In the past I would have used #Leaflet or #mapbox. #d3 would be overkill for this use case.

Thanks!
