How to convert Lat/Long to UTM using Proj(4j) similar to JScience UTM.latLongToUTM?
If you're using WGS84, for a northern hemisphere zone, concatenate 326 + zone number. For a southern hemisphere zone, concatenate 327 + zone number. The 326 comes from 4326, the code for a 2D WGS84.

How to reproject data in multiple UTM zones? (DRCongo, Rwanda and Uganda)
The area of interest only crosses into UTM zone 36 south by a few degrees. It would be fine to use UTM 35 South for the entire area. UTM is a conformal projection which maintains shape. …

Converting LiDAR .las to .xyz with LAStools outputs incorrect projected coordinates?
I didn't expect that this would be the answer, but it turns out that las2las uses the UTM latitude band letters rather than the hemisphere 'N' (North) or 'S' (South) letters with the zone number. … 17T
>> las2las -i TO_core_last_zoom.laz -o out.laz -utm 17T -target_latlong
Note the '-utm 17T'. …

Transform from WGS84 to EPSG 3785 (google maps)
So you have two conversions to do: UTM to latitude,longitude and latitude,longitude to EPSG:3857 (EPSG:3785 has been deprecated and replaced with 3857). … UTM is based on tranverse Mercator and knowing the UTM zone allows you to figure out the parameter values. To convert to EPSG:3857, you will need the sphere-based equations for Mercator. …
