> niche brands are not a thing of this century alone Sure, but targeting ads enabled a massive increase in volume of niche brands. In particular, brands whose target customer is fairly specific (so totally untargeted ads, like TV commerc

Thank you for the clarification. Obviously I did not know that about Safari & IDFA. If that's the case though, I'm a bit confused as to why attribution got so much worse. I'm seeing 50% attribution dropoff.

I don't agree with you that ruhdgjns is not engaging in good faith. He's engaging with my comment. Given that I am a D2C business owner and therefore a modern advertiser, that's a pretty reasonable view for him to consider. R

Apple made accessing a devices IDFA (device fingerprint) a permissioned resource. Needless to say it is not a popular permission to grant. Cross-app activity can't be tracked without this permission. So if you see an ad for a product o

FWIW I run a D2C brand and the iOS 14 change hurt badly. We are able to attribute something like half of the sales we used to. The main consequence of this is the FB models can't learn who our customers are as well, resulting in an inc

I wrote another post that is both an homage to Google Earth and an illustration of how these maps differ: If Google Earth Were Designed For Your Wall: https://ramblemaps.com/if-google-earth-were-designed-for-wal...

It’s actually a custom form (not canned) and we had previously had an additional field for area of interest but it lowered the conversion rate of the form so we dropped it. Getting emails is more important to our business than knowing where

That step could certainly be its own post of greater length than this one. For this particular map it involves separate curve adjustment layers for the water and land. We generally increase the steepness of the curve (increasing contrast) a

Thanks for the link. We used Lambert Conformal Conic for Europe and Robinson for Asia, but I'm not thrilled with the Asia projection. I really want to be able to change the latitude the projection is centered on, but haven't been

We sell wall art. You likely don't look at a painting by your favorite artist and say "This is overpriced. I bet the canvas and paint only cost $10." Also, Ramble Maps is a business. We have material costs, shipping costs, ad

Thank you! It's a question we often get, but not a product we're looking to pursue. I think it would be prohibitively expensive to do it right and I'm not confident there's a big enough market for it. I could be dead wro

Thank you! Unfortunately we won't be doing any choose-your-own maps, we really do spend a bunch of time on each one. I don't think we could maintain nearly the level of quality that we like. I'd love to map Sydney. We're

> Have you considered transfering your methods from the macro to the micro world? Not to this point, but it's a very interesting idea. Someone else mentioned electron micrograph imagery, which would look incredible.

I assume you're referring to the azimuth we place the sun for the hillshade? If so, it varies, though it is almost always coming from the top, generally from the upper left. Exactly where it is coming from depends on the terrain, we&#x

We've got mars and the moon on the site. I've been wanting to do some of the recently released Martian craters. They would look killer! I've never thought of electron micrographs but just did a google image search and wow, I

We settled on this choice after originally using alternate projections. The source data is not in mercator, we specifically reproject to mercator. I don't disagree with you, I personally prefer other projections for many of our maps, b

All public. At this point if the data doesn't exist, we're out of luck. I don't anticipate wall art being lucrative enough to commission our own scans. For areas the size of what we tend to map you need an airplane, a drone w

Nope, the state maps are pure elevation maps. We do have some city maps and are working on more right now (Seattle and LA are in progress).

Our black and white images (such as the image on the linked article) aren't satellite images at all, they are high resolution elevation models that we've used GIS software to light and create hillshade. We do have some color image
