Would be an interesting project.. An old link to possibly still useful code:
http://wiki.squeak.org/squeak/3317 Btw the shapefile support, from the ESRI spec, was done by me and is still available on http://www.squeaksource.com/@CUT95k_uXmPU4uXY/HCmgtrop. I use it daily. I may have some fixes/additions, but in general the code as provided works well (I suppose the code at smalltalkhub is still mostly the same). Some shapefile formats are still missing, mostly because I never encountered them.. To read a complete shapefile one also needs to read dbf files. This was another substantial effort http://www.squeaksource.com/@Y4HhnL90iyA2TmAb/X0sPqshM; luckily there was an older implementation.available to build upon. Not sure whether nowadays there are other ways to read/write files old DBASE format files...

Working on CORMAS multi-agent simulation platform: https://github.com/cormas/cormas some developers feel the need to have more GIS support for Pharo. I know of existing GIS software: - GeoJSON by Zweidenker: https://github.com/zweidenker/GeoJSON - ESRI ascii raster, done by Stephane recently: https://github.com/Ducasse/ESRI-ASCII-Raster - shapefile support by Hernan: http://smalltalkhub.com/#!/~hernan/Shapes (to be moved to github) - I found this project also: http://www.squeaksource.com/gekon.html I know that Etienne Delay is also interested by GIS support and propose to implement OpenGIS model support: https://github.com/cormas/cormas/issues/139 Can we try to unite and maybe create a pharo-GIS organization on github to federate our efforts?
