This talk is intended for GIS users & managers who may be interested in open source GIS but aren't sure what the advantages to them might be, or who think Open Source GIS is nice in principle but are afraid there's no space for it in their workplace. In general, "Do This, and also That..." wants to address concerns of professionals who aren't sure how or why to make the leap from traditional/proprietary GIS tools into the wide world of Open Source GIS.Drawing from my own experiences, my goal is to gently present an integrated approach to open source GIS. This is not an "all or nothing" scenario: I want to show the audience how effective workflow solutions can involve both open source GIS as well as "traditional" proprietary GIS they are familiar with.I will briefly discuss common issues faced by GIS users, and explore the benefits of integrating open-source based workflows alongside proprietary GIS. I will cover use-cases for Leaflet and OpenLayers, OGR2OGR, PostGIS, and QGIS. Each use-case will demo a quick and friendly example of how a particular real-world issue might be addressed by the inclusion of one of these open source options into an existing GIS stack.
