Re: [Pharo-users] GPS / Longitude / Latitude library

by CÃ©drick BÃ©ler

Interesting. Iâm interested with such tools too. I ask students to do gps point collection from mobile (Cordova) and process them in pharo to detect if they enter known places. I wonder if a proper gps point class would be useful. Iâd like to record also the precision.

I have long wanted to do a FFI interface to GDAL. I think Pharo would make a great GIS workbench.

Hi Sven, Thanks. This is just for me playing around with my photo collection, i.e. find all photos from a particular location, i.e. within a specified distance of a point. Also maybe add GPS coordinates to some photos.

This is not open source, but it is not rocket science either (just implementations of public algorithms). We have less need for special conversions, we do them case by case when they occur. What are you planning to do ? Sven
