SMASH

Hydrologis, is the mini-company formed by Andrea Antonello and Silvia Franceschi (GS). Notwithstanding they are just two they accomplished really a lot in their career in the world of Open and Free GIS, where they have a solid reputation. First they built, when collaborating with me, the JGrass GIS that eventually was a clean part of the udig GIS. In contemporary Andrea, for his Ph.D. wrote BeeGIS whose ideas, with exploding the mobile devices wave, flowed into GEOpaparazzi that works with Android OS and can be downloaded from GooglePlay. In the meanwhile they also produced a port of the Horton Machine into gvsig  and as standalone (download the executable from here, the Horton Machine is on Github). I forgot LESTO (EGU Abstract), the product for analysis of LIDAR signals that Silvia developed for her Ph.D.

Now, finally it arrives SMASH  (IOS, Android), the new tool for digital field mapping that work on the two main mobile platform. To describe how it works, Silvia made a video which I uploaded to my VIMEO channel. Unfortunately it is in Italian.

Hoping soon we will have one in English. All the best!

Updated material on Horton Machine

The Horton Machine is our set of tools for terrain analysis actually maintained by Hydrologis. They since 2000 and something took care of keeping my tools alive on various platforms: GRASS, JGrass, uDig and now on gvSIG. We also have a porting of the Horton machine that works under GEOframe but is the same codebase.

Silvia Franceschi and Andrea Antonello gave a tutorial at this year gvSIG conference and here it is the material.

You can find the same material also at this osf project. Soon they will follow some theoretical lectures.

The Horton Machine (formerly known also as JGrasstools) is back

The Horton Machine, the set of tools I developed several years ago with Hydrologis, is now back and well documented in gvSIG. All the merit goes to Andrea Antonello and Silvia Franceschi, the "Hydrologissers'.  I could not support new work on GIS (after my decade of involvement) but they were so kind to make me co-author of their presentations. During the last FOSS4G in Guimãraes they presented what they ported into  gvSIG and prepared some illustrative material that we share with you.

You can find:

• The Introduction/presentation given in Guimãraes
• The material of the workshop given by Silvia and Andrea
• A quick introduction for the installation of the Horton Machine plugin
• The Tutorial
• The DEM the can be used as example

gvSIG Festival

gvSIG is the platform where are migrating my contributions to GIS, thanks to Hydrologis. It is my intention, obviously, to embrace it from version 2.3, hoping that this will be the home sweet home I deeply desired in the last years. In preparing the arrival of the version that contains my tools, the developers had the idea of a nice initiative called gvSIG Festival where many developers were asked to explain their work.

There you can find a lot of useful information. Not specifically about hydrology but someone are. Clicking on the figure you will access the main page. Video Presentations are here.

Renjin

Renjin is a JVM-based interpreter for the R language. For Java developers  of scientific application, I think it is a must (but still I need to test it). It can be used in various ways and offers itself a simple interface to be used. The fraction of packages ported into it is here. 
For an introduction you can watch this webinar. But obviously you can have more by browsing Rnjin website.

Among others, gvSIG uses Renjin for making calculations.  The source code is available on GIThub.
