During the workshop a variety of examples, as well as live coding, are shown using Leaflet as a mapping client, but participants will also be shown how to use Turf.js with OpenLayers. Participants will first be taught how to set up a simple map and then will be walked through preparing datasets from various formats (e.g., KML, GPX, Shapefile), so they can be used with Turf.js, which requires GeoJSON as input. This will be followed by the presentation of various tools, as well as the combination of them, to conduct meaningful geospatial analysis and queries, whose results can be displayed and exported.
This workshop is taught by the author of the Leaflet Cookbook - Recipes for Creating Dynamic Web Maps (Locate Press, 2019).
Web development knowledge is a benefit, but not a necessity. The workshop will focus on Turf and anything related to general web dev of Leaflet will be explicitly mentioned and explained, if need be. All data, code, and outcomes will be shared. Feel free to simply sit back and enjoy! If you want to follow along, all you need is a simple text editor (or your IDE of choice). I will show how to convert various vector formats to GeoJSON using QGIS. If you don’t have QGIS I can share the outcomes with you (but you should nevertheless probably get QGIS, because it’s a really, really good product :-)).
