<div dir="ltr"><div>Hello everyone,<br></div><div><br></div><div>As part of my recently completed <a href="https://digitalcommons.lsu.edu/gradschool_theses/5641/" target="_blank">masters thesis</a> I created an extension for GeoNode that allows users to georeference (georectify) Documents directly in the browser (a la <a href="https://mapwarper.net/" target="_blank">Map Warper</a>) and turn them into GeoNode raster Layers. I presented a short introduction to the concept at the GeoNode Summit 2020. The project repository is here: <a href="https://github.com/mradamcox/loc-insurancemaps" target="_blank">https://github.com/mradamcox/loc-insurancemaps</a>.<br></div><div><br></div><div><div>I worked hard to
construct the georeferencing extension such that it could be added to
any existing GeoNode implementation. However, it still needs to be
repackaged, and some aspects of it should be reworked (e.g. how the
GeoTIFFs are ingested into GeoServer/GeoNode), before it's ready for
wide adoption. Here is <a href="https://docs.oldinsurancemaps.net/en/latest/#extra/" target="_blank">documentation</a> on its design (much, much more in the paper linked above).<br></div><div></div><div></div></div><div><br></div><div>My original motivation was to facilitate crowdsourced georeferencing of large historical map collections, so I also conducted a public pilot project from Feb-May of this year, implementing this extension and further custom work at <a href="https://oldinsurancemap.net" target="_blank">oldinsurancemap.net</a>. Over 35 people participated in some way, and about 1,500 documents were georeferenced. Ultimately, for my specific project I think GeoNode was more complex and resource-intensive than what I really needed. However, this extension worked well, and I still think it could add considerable value to other people's GeoNode implementations (especially cultural heritage or municipal implementations); to my knowledge, browser-based georeferencing is a capability that ArcGIS Online does not have.</div><div></div><div><div><div><br></div><div><b>So: If you or your organization is interested in supporting or implementing this georeferencing extension, please reach out to me</b>. I have finished my degree program and am looking around for what comes next.</div></div></div><div><br></div><div><div></div><div></div><div>Finally, I'd like to give a big <i><b>thank you</b></i>
to everyone here who helped me throughout the course of this project, especially
on the Gitter chat! I learned a lot from working with GeoNode, and will stay tuned and try to contribute when I can.</div></div><div><br></div><div>Thanks,</div><div></div><div>Adam Cox</div><div><a href="mailto:mr.adamcox@gmail.com" target="_blank">mr.adamcox@gmail.com</a></div><div><br></div><div><br></div><div><br></div></div>
