The names did not have a prefix, so I created a new field on the attribute table to add the word “Rio” before the river names – it means “river” in Portuguese. I adjusted the symbology of the lakes and rivers and added labels to the rivers. Some styling, such as labels styles, may not be 100% translated to Leaflet.įor this step, I load the data and zoom to a location on Brazil. Base maps, however, are usually loaded on demand. Keep in mind that large rasters take some time to export and may not load correctly in some browsers. First: open your QGIS project and adjust the symbologyīefore exporting your map, you should adjust the symbology as much as possible, so that it looks how it should look on your webmap. Data used: Natural Earth public domain land cover, rivers, and lakes, Google Maps © Google base map. No advanced coding skills are required to do such modifications, although this will be easier if you have basic coding skills.įor the next steps, I will be using QGIS 3.16 “Hannover” Desktop. This map was generated by qgis2web plugin on QGIS, and further edited directly on the generated code. Load example Leaflet.js webmap Frames are not supported. Please notice that this map can take some time to load in slower connections. Plus, I will show you how to implement Leaflet.MousePosition to show the coordinates on hover.Ī simplified version of the webmap I show how to generate in this post can be loaded by clicking on the button below. In this post, I am going to explain how I take advantage of qgis2web to generate a basic webmap, and what I should look out to alter after the map export. I generate my basic map using as many specifications available on qgis2web as possible, and then, edit the html and the JavaScript generated by the plugin to adjust the map to my needs. But, because I am a QGIS enthusiast and many of my maps are already on QGIS projects, I can get the best of both worlds. Leaflet maps can definitely be generated from scratch. My favorite is Leaflet, also called Leaflet.js, which is relatively light to load, and has solid documentation to support its use. All of them generate simple, but good-looking maps, with contemporary style. To do that, you can choose between the (currently, version 3.16) three types of webmap: OpenLayers, Leaflet, and Mapbox GLJS. Qgis2web is used to export your current QGIS project as a webmap. Today, I will still be discussing qgis2web, but the adjustments to make on the map after exporting. ![]() Last week, I showed a workaround to avoid qgis2web generate a webmap preview when you change the map type, freezing QGIS. ![]() I also do not authorize any copies of my content. I have no responsibility if you lose data or mess up your installation. I’d like to start with a disclaimer – I may be a researcher of this very area but that doesn’t mean everything I do or write here will work for you, in your own desktop configurations and package versions. Fellow researchers and open-source GIS enthusiasts,
