ArcheOS new issue on GitHub repository (how to)

In order to simplify reports regarding ArcheOS from the community, I just uploaded on YouTube a short videotutorial which shows how to register a new issue on our main repository on GitHub.

Here is the video:

I am sorry for the low quality, but I think you can understand the single steps. Next time I will try to do it better :).

Have a nice day!

Polygontool

Hi all,

this fast post is intended to be an overview of the new open source software Polygontool, an application our friend +Szabolcs Köllö (aka +keulemaster) developed for Arc-Team. This tool is helping us in defining an automatic data processing protocol, in order to directly convert raw data files (collected with RTK GPS or total station during survey campaigns) into GIS readable formats. Currently the tool is under an hard test phase, being used during an interreg project (leaded by +Rupert Gietl) about the Great War between the Austrian and Italian border, but it had already positive effects on our work-flow, reducing the time expensive operations of manual data processing. The short video below is a demo to explain how the software works and what it can do.

The source code (in Python) can be found on github and it is already usable (if you want to test it) and open to contributions (if you want to help us in the development). Currently the configuration files (in the "config" folder) are optimized for our interreg project, but you can, of course, modify the terminology to make them fit to any other archaeological database.

Soon I will post other reports about Polygontool. By now I hope this preview will be useful for some of you (and maybe for us, if someone will join the project).

Have a nice day!

Raw data to WKT: a line

Hi all,

Again a short videotutorial about FLOSS in archeology. In the last one we saw how to turn raw data (from the total station) into the WKT code of a point; this time we will see how to create a line. 

This videotutorial is also available on the DADP wiki (I updated the old tutorial). 

Like before, the system I am using is a preview version of ArcheOS Theodoric, done building the iso image just following the instruction of the readme file on the github page.

Now, thanks to +Fabrizio Furnari we also have the project for an ArcheOS manual (still work in progress). If you want to help us, you will find the code on the github page (yes, we like github very much...). 

A great help it would be to translate these videotutorials into text :). If you want to participate to the documentation, you can contact us in many ways (also commenting this post), like the official IRC channel #archeos, or the developer mailing list (for more info, read the text here)

Here is the video, I hope it will be useful!

Software recovery: e-foto rectification module for 64 bit

As you can see from this mail (ArcheOS developer mailing list), since July 2011 one of the problem in mainatinnig ArcheOS e-foto package was related with the rectification module of this software. In fact this module seems to be abbandoned in the latest releases. Unfortunatly this code is very important for our archaeological field-work, being connected with the Metodo Aramus (the procedure we use to obtain georeferencad photomosaics).

e-foto's rectification module at work (Metodo Aramus)

For this reason I fisrt tried to contact the software developers (in the official forum) and then, having too few time to dedicate to this problem (I know, my fault...), I decide to upload the code on github at this link: https://github.com/archeos/rectify. This solution should help to keep the rectification module of e-foto ("rectify") an active project as a stand-alone application, avoiding the risk to become an abbandonware.

However, looking to the development of ArcheOS new release (codename Theodoric), there was still a big problem: I was not able to compile "rectify" with Qt4 also for 64 bit, as ArcheOS 5 should have both a 32 and a 64 bit version.

To solve this situation I asked again the help of the community, writing a post in the italian Qt forum. As you can see from the discussion (sorry, just italian) an user (Tom) helped me in updating the source code. It was necessary to modify just two files: matriz.cpp and matriz.h, so I did a new commit on github and now the code is ready to be compiled with Qt4. I did not yet packaged rectify for 64 bit, but I will do it ASAP. Anyway if someone has this kind of machine and needs to compile the module, he can use the source-code in github (It should work, but if there are problems please report them).

I hope it was usefull.

Ciao.

Good news from PMVS2

According to Pierre Moulon's Blog a new implementation (from Nghia Ho) has been integrated in CMVS-PMVS. The result should be a faster (up to 30%) data elaboration. We will start with the test as soon as possible and, in case, a new ArcheOS package for PPT (Python Photogrammetry Toolbox) and PPT-GUI will be released. For who wants to collaborate in PPT-GUI development, here is the link on GitHub.

In the video below are some archaeological examples done with this software.
