comment Why ArcGIS Runtime SDK for .NET Toolkit is made as open source?
I know this sounds like nit-picking - but this is a common mistake. "open source" and "commercial" are not mutually exclusive. Many Open Source packages are commercial. The comparison should be "open source" vs "proprietary software".

comment how to transfer GPS device coordinates into mobile android app?
@Elasri05GIS You can use a wide range of external GNSS receivers (or internal). If you really need to, you can get up to 2cm horizontal accuracy. The link I gave you above is the source code to our mobile application at amigocloud.com which is our hosted service.

you may want to look at the open source project that we built that does that: github.com/amigocloud/amigoclient

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"?

comment Why esriSpatialRelTouches relation does not work?
havk for internal memory management. If the filter owns the geometry, then in each loop it can assume it won't change so you can save a deep clone of it in the internals. A classic case where this happens is when you use the geometry of a feature that came from a recycling cursor. On every iteration that geometry will change. Honestly, IMHO it should just always deep clone and forget about it.

comment What is the difference between Coverage, Shapefiles and Geodatabases in ArcGIS?
@PolyGeo You are right. Fun fact: SDE supported Access databases at one point. You can see that in the ArcSDE API for grabbing connection info: help.arcgis.com/en/geodatabase/10.0/sdk/arcsde/api/capi/… SE_DBMS_IS_JET is for the MS Jet Engine en.wikipedia.org/wiki/Microsoft_Jet_Database_Engine

Makes sense. GDB 10.x and higher use a radically different GDB schema...

Yes. There are instructions for Linux and Mac that are very straight forward.

comment How to perform Full Text Search of Esri geodatabase?
I'd also point out that "Full text search", nowadays, is about doing semantic searches. This means that synonyms and the Levenshtein distance should be taken into account for the search... not just case-insensitive string matching.
