QGIS VS OpenLayers3

Prepare GIS data for use with Amazon Athena. This time, we created four types of sample data in QGIS in advance.

I am using Qgis to try to edit the map database and add polygon territories for any future changes to the GeoJSON that I created/edited.

Judging by this open issue in the QGIS repo it doesn't seem to be possible to skip fully transparent tiles.

In the most generic, high level way: grab the source code, start up a debugging session with a profiler, and see what/where the bottleneck is. Bonus points for documenting the issue and submitting a bug report. Extra double bonus points for opening a pull request to

Hi! I used QGIS to create the map and BRouter to create the lines as routes. Does help that GIS is one of the major parts of my profession so I'm fairly familiar with designing maps

qgis Desktop software.

Oh hm i may have misunderstood this answer: https://github.com/qgis/QGIS/pull/36683

Adding natural breaks to symbology for rasters is an open feature request (since 2020) https://github.com/qgis/QGIS/issues/39746

You probably know this, but in Google Maps at least, you can use browser zoom (ctrl/cmd +/-) to change the size of labels without zooming into the actual map.

Speaking of maps, I got to work a fun zoom project a few years ago: https://map.fieldmuseum.org/

We used https://openlayers.org/ and thought long and hard about how to best handle zooming and variable levels of information density & visual hierarchy. If you zoom all the way out, we just highlight where the building is relative to the surroundings. As you start to zoom in, we start to highlight major exhibitions and entrances. Then as you zoom in more, we start showing recommended paths, smaller exhibitions, etc. The label sizes try to scale up and down at each level, smoothly, in order to balance readability and density.

Eventually you can reach the max zoom level and the labels will just grow bigger and bigger, but the SVGs dynamically shrink so they remain pictograms and not just contextless-lines.

Then if you keep going, you eventually find microscopic easter eggs :)

The code is pretty jank (and abandoned), but it's FOSS vanilla JS/HTML/CSS, and the only dependency is on OpenLayers: https://github.com/arcataroger/openlayers_indoor_map

In order to display the GeoJSON features on a map, we will use OpenLayers, which is a very powerful open-source mapping library that is also very simple to use.

OpenLayers is available via the ol npm package, offering developers a powerful toolkit for creating sophisticated maps. Here is a JavaScript implementation that utilizes OpenLayers to showcase a map:

For web maps I'd strongly recommend using OpenLayers. While it's less convenient to get started with compared to the alternatives it's also much more feature-complete and you'll likely hit a ceiling in terms of functionality much later than you would with the others.
