Last time we had the task to create mountain ranges polygons for the whole world. I prepared a small tutorial referred to that. Maybe you can find something interesting for you. It will show you a model on how to select defined regions, slicing raster, smoothing and also exporting desired features. Enjoy!
I often find myself in a situation where I want to work with large areas and datasets of OpenStreetMap data. No matter if you want to use them in a QGIS map or create custom map tiles in Tilemill, with the Overpass API you quickly run into performance issues. Imposm is a great tool to overcome that situation, so you can load OSM extracts (worldfiles in pbf format) with a custom data mapping into a PostGIS enabled PostgreSQL database. The downside: It is hard to set up if you are not a database and system admin guru. This is where…
Mapalomalia lets geologists create and visualize 3D geological models from their browsers. It’s a free to use geological modeling platform. I hope people will use it to convey information about our planet that helps humankind to tackle big problems and at the same times makes geological modeling easier. I have developed it with input from many geologists, and by releasing it early I hope to receive more input from many more geologists. Just sign up here to start creating models.
Today I received the newsletter from Mapbox with interesting screenshots of their new mapstyles. The company convinced many users with nice basemap styles already in the past. Now they updated their background mapstyles for webmap usage. Just have a look: All pictures are from Mapbox. In my opinion the new styles fits good for modern map applications. If you’re interested in other background maps, check out this article – Map Compare. If you’re interested in getting more information about Mapbox styles, just visit this Mapbox article.
