Thanks so much to OGRIP for giving OVRDC the chance to share our experiences utilizing the Leaflet javascript web mapping library at the 2015 Ohio GIS Conference. Below are links to the pdf, online and zipped versions of the presentation. The pdf is a printed version of the reveal.js presentation and has some flaws, but the links do work. The zipped version is slightly modified, with the complex map example fine tuned to open in a web browser as-is, without the need to host the map on a web server – for the basemaps to work you will still need an internet connection. The presentation does load a 40mb data file to build geojson tiles, so be patient.
