comment Juno 3D open source software
This is not for the faint of heart, but you can install Android in a Windows Mobile phone and then you have a lot of options: stackoverflow.com/questions/8601675/… One of those options is our open source mobile data collection client which is shown here: youtube.com/watch?v=lj6OeTZgzM8 A caveat is that although the mobile client is open source, the SaaS service has a free tier, but is not 100% open source.

comment How to create Vector Polygons at the same amazing speeds GISCloud is able to render them?
Four years later there are many things that have evolved and this textbox only has ~500 chars to explain it. The summary is that WebGL is mature and, beyond serialization techniques, people have been applying fixed-precision delta-encoding (like we used to in the 60s) in formats like Topojson. This is a good thing. I'd love to see some of these things in a standards from the OGC... nevertheless, the politics around the OGC have been very complex lately. Here are my feelings from two years ago: blog.burhum.com/post/50036141569/the-ogc-is-stuck-in-1999

comment How to improve performance when using a large amount of data (big tables) in ArcGIS?
@AndresMurilloLopez before you optimize anything, you need to understand what is the slowest part of your algorithm. Did you use a line profiler to figure out where to start? zapier.com/engineering/profiling-python-boss

comment File Geodatabase (*.gdb) support in QGIS?
If you are using homebrew you should stay away from the KyngChaos binaries or you can potentially have problems during compilations since you will end up with multiple versions of gdal.

comment File Geodatabase (*.gdb) support in QGIS?
Well, the answer was from 2012. :) In the past three years, many changes have happened. You can compile without any special magic using homebrew and it is available in the OSGeo Windows distribution, too.

comment Free Android library to display tiles
vector tiles or raster tiles? would you be OK with having the client reprojecting on the fly or do you want to show the coordinates "as is"?
