The programme looks very good and I may well use it for other things in the futre, now that I have found it, but for now I just need to be able to find a solution to printing large PDFs across a network, which means I need to convert them to vector-based. I turned off "Rasterise filter affects" and saved, but it did not save the page in vector format.

I just assume this is a limitation and can live with that. It was 7 pages and inkscape only loaded one page.

I have installed it (v0.92) and loaded a PDF. What I read about it lead me to believe that it would be able to convert my PDFs. For this tutorial we have used Inkscape for the conversion of the PDF to DXF, QGIS to extract some information of the DXF, Python and Geopandas on a Jupyter Lab session for spatial translation and scaling.I was look round for a programme to allow me to convert raster-based PDFs to vector-based, as the EMF created when printing is very large.

We have done a complete tutorial with all the step required to extract the vector spatial data of a map reported as PDF into a ESRI shapefile. The amount of tools and techniques are quite advanced, and requires several open source software for specific procedures. In order to use the spatial data provided on a report we need procedures to extract the data on effective way. However, most times, the disorder and limited resources of public / private institutions makes the data available just on reports in digital version (as PDF) and even as paper based reports. In order to give a complete value of this spatial data, it has to be stored in special OGC standards and ESRI Shapefiles, GeoJson, Klm, NetCDF, in commercial / open source databases, on web repositories.

Vector spatial data is a type of data, that are points, lines and polygons with related information. We publish reports, we create tables and maps, but we are more focused on giving opinion and evaluations rather than in preserving the data that someone else can review and incorporate to its own study or reanalyze and provide a complete different evaluation. Modern times records lots of data, and computational software can deal with high amount of data, but we certainly haven’t been able to store efficiently data.
