maplibre-gl-js VS aws-sdk-js

(.shp .gpkg ...) | ogr2ogr -> .geojson | tippecanoe -> .pmtiles

for OpenStreetMap data there's planetiler[4], and and openmaptiles[5] styles that work with Maplibre

with those combinations you've got a great start to something you can host for pennies on AWS S3+CloudFront or Cloudflare R2, with an open source data pipeline

MapLibre GL JS v3.3.1

Does anyone else have a solution for the satellite layer? I was using MapLibre [0] then needed direct-on-the-ground images which made me convert to Google Maps.

When using the Amazon Location Service, I recommend MapLibre GL JS, which I introduced in my previous article, "Amazon Location Service and AWS Amplify to Use Various Map Library," but you can also use any map library you like, including iTowns this time. I hope you will choose the map library of your choice, including iTowns!

Your browser has a very powerful image decoder built into it, offloading the PNG decoding into Javascript is very resource hungry.

Using maplibre (or any map viewer) you can load blobs of image data out of a tiff and use `Image` or `Canvas` to render the data onto a map.

Its even easier if the tiffs are already Cloud optimized as they perfectly align to a 1-to-1 map tile and they don't need to be rescaled, you can then just render the images onto the map. eg here is a viewer that loads webps out of a 15GB tiff and uses Canvas to render them onto a map [1]

Unless you are trying to layer all your maps together, you also could stop reprojecting them into webmercator, or if your goal is to layer them, then storing them in webmercator would save a ton of user's compute time.

There are a bunch of us that talk web maping and imagery in the #maplibre and #imagery slack channels in OSMUS's slack [2]

The map is rendered by https://maplibre.org/, you can see how it is used here https://github.com/anvaka/map-of-github

Kudos to https://maplibre.org/ - amazing library

⚠️Here's the issue: https://github.com/aws/aws-sdk-js/issues/4519

The updates could be parsed from the github repo's CHANGELOG files (ex: javascript, java, python). I'm picturing an RSS feed generated for a specific language and module (ex: python s3, javascript s3, java sqs)

Another option is to look at the changelog for the AWS SDK. Because the AWS SDK has to have support for pretty much every service ever it gets a new version and a changelog whenever new things are added. I like to refer to this changelog from time to time: https://github.com/aws/aws-sdk-js/blob/master/CHANGELOG.md

From this thread I double-checked that all query strings and the origin, Access-Control-Request-Method and Access-Control-Request-Headers are sent to the origin (I ran into some signature mismatch issues before that were solved with this origin request policy).

Now that you have installed MinIO server, let's use it on your project. I will be using the official S3 JavaScript SDK as example. But should be applicable for all other S3 SDKs.

The client is only available for Java and Python. https://github.com/aws/aws-sdk-js/issues/1164

The best way I've found to locate the X-Amz-Target value is from this AWS support ticket where it is recommend to look at the SDK docs for the service and locate the targetPrefix field in the metadata.

I wonder if there's a way to only bring in the S3 SDK from aws-sdk to help trim the file size. I believe there might be a way to import only certain files, maybe something like this?

Due to performance reasons, one of the goals was to switch to rollup for bundling all our applications, however, we use webpack due to rollup’s known issues with aws-sdk.
