Short Announcement: OpenWhateverMap

Choosing a basemap for your cool web map is always crucial for the style and perception of your map. A colorful basemap like watercolor might be stunning but also interfering with your data visualization. In contrary a grayish basemap might look a bit boring but your data visualization will be crucial. If you’re unsure and a playful type of developer: Use OpenWhateverMap!

OpenWhateverMap

QGIS as well as ArcGIS Desktop let you choose your favourite basemap. In terms of QGIS most of you might use QuickMapServices from NextGIS (don’t use openlayers!). In ArcGIS you might use the default basemaps or add your own basemap to your project. In the end you get a great variety of basemaps in the GIS of your choice:
But why should you choose between many if you don’t know how they look and feel? OpenWhateverMap gives you a nice little leaflet based webmap to compare the stiles of different tile-providers like Mapbox, OpenStreetmap, Carto and many more.

Adopt OpenWhateverMap

It is a simple html/leaflet webmap you can create your pretty and customized version according to your own needs:

Unfortunately I don’t know who owns the domain (the who.is information is quiet sparse) and github only provides the user Ilja Zverev you might want to contact the twitter user in case of questions or remarks.
