You can easily try JDONREFv4 with ElasticSearch but data is not included.

You can probably do this in the browser with WebGL: http://www.html5rocks.com/en/tutorials/webgl/webgl_fundamentals/ but it would require some programming, and a WebGL-compliant browser. But it should be fast since it would be using the GPU in most cases.

I think you have a few options. 1) ArcGIS online if your data are limited and you just want to get it online (they have free limited use for individuals). 2) Mapserver if you need something more robust and are more server focused. 3) Leaflet if want you want is more mobile. But as whitebox says, it depends exactly what features of Tableau you want (want ...

I believe that I have found an adequate solution that meets all of my requirements. Thanks to user30184's answer, which pointed me in the direction of ImageIO, I was able to find an alternative Java imaging library called Apache Commons Imaging. It is a pure-Java library that consists of a single small JAR file. It also supports both reading and writing of ...

Boundless has a tool called GeoGig: http://geogig.org/ Users are able to import raw geospatial data (currently from Shapefiles, PostGIS or SpatiaLite) in to a repository where every change to the data is tracked. These changes can be viewed in a history, reverted to older versions, branched in to sandboxed areas, merged back in, and pushed to ...

Install OpenJUMP and study what all has been gathered into it I have never really understood what all the alternatives are. ImageIO-ext is probably utilising native GDAL binaries if such are available but at least most other alternatives are pure java. There is also one more alternative in OpenJUMP called "Sextante raster" which is also pure java. ...

I would suggest Grass GIS. The v.net package is a pretty powerful tool. Grass can be a bit tricky to get going on but with a tutorial or two you should be OK. You will also need to interpret the matrix result that will be ~200 by ~200 with the distances. Export to excel, import with Python, etc. and do what needs doing with it. ...

Using only open source software, you will almost certainly need to do some programming yourself. GDAL is the de facto open source raster I/O library, so you will probably be using it or one of its many wrappers. You could use Python (e.g. rasterio + numpy/scipy) or node.js, e.g. node-gdal (though beware it is currently synchronous/blocking). As for actually ...

What you are looking for is an image server. ArcGIS for Server has this extension: ArcGIS Image Extension for Server i do not know of any open source equivalents.

TileMill is released under the BSD 3-clause license, an OSI approved license. https://github.com/mapbox/tilemill/blob/master/LICENSE.md So in answer to your question: Yes, TileMill is open source. Mapbox Studio is released under similar terms: https://github.com/mapbox/mapbox-studio/blob/mb-pages/LICENSE.md Some more information: ...

From GWR by Roger Bivand: Geographically weighted regression (GWR) is an exploratory technique mainly intended to indicate where non-stationarity is taking place on the map, that is where locally weighted regression coefficients move away from their global values. Its basis is the concern that the fitted coefficient values of a global model, ...

For the sake of completeness. I believe this should be a comment on Regan response. But since I don't have enough reputation I'll leave it as a response. The DXF writer supports 2.5D layers, and given a line input, should output a 3D linestring on dxf. In the case of input POLYGONS you have to be more careful, since the driver defaults to generate a dxf ...

You could set up a Web Processing Service (WPS) with Zoo-project.org and GRASS GIS. For pointers, see http://grasswiki.osgeo.org/wiki/Interpolation - "Reinterpolation of 'sparse' (scattered points or lines) maps" and also http://grasswiki.osgeo.org/wiki/WPS. QGIS offers a WPS client which you can then run to use your WPS interpolation service.
