Would be an interesting project..

An old link to possibly still useful code:

Btw the shapefile support, from the ESRI spec, was done by me and is still available onhttp://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 efforthttp://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...

Subject: [Pharo-users] GIS support for Pharo

 

Dear all,

 

there was already some discussion in the list about GIS support for Pharo previously.

 

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?

Cheers,
