Geopaparazzi (almost only) bugfix release 4.1.1

A user from the Italian GFOSS mailinglist made me aware of a nasty bug in the new polygon editing system. Basically when merging two polygons creating a new polygon, the result would not be written on a multipolygon layer, which is simply wrong.

This has been fixed and since there was also a small leftover checkbox on the new project creation dialog (which looked really really ugly) I decided to do a bugfix release.

I also threw in language updates.

Why were they necessary?
Well because obviously in the meanwhile a new feature entered Geopaparazzi.

It is now possible to continue a previously closed log. When you start a new log you will now have a checkbox available that by default is set to off. If for any reason you want to continue from the previously closed log, check that one. No new log will be created, data will be attached to the last inserted.

Pay attention to what you do though. The system will not care about the fact, that the previous log was closed a week before. You might have strange results in the speed chart :-)

Geopaparazzi 4.1.0 is out: beam it to me!

Well, as sad as I am that Geopaparazzi 4.1.0 doesn't support Android versions before 4.1, it was definitely time to move on from version 2.3. For those with older devices version 3 of geopaparazzi will hopefully work.

This gave me finally the possibility to do something I dream of since watching Star Trek as a kid: BEAMING!!!

So this will be presented as feature number one for this new version. :-D

1) Beaming of gps logs between devices

Assume you are on a survey and your battery is dying. Assume you have a second device you can use with full battery. You need to send the data over in order to continue your project there.

Well, one version is to somehow share your project database through wifi (if available) or connecting to a pc.

Well, now you have a much quicker way, even if for now only for gps tracks (and only if your phone supports NFC).

Make sure NFC is activated and follow this short howto:

Isn't that incredibly cool? :-)

2) Share your current position

Well, lately one thing made me very upset. My mother, which uses geopaparazzi when she goes hiking, used to share her position through the SMS function (the one available from the panic view). She recently upgraded her mobile plan with internet connection and started to share her position through telegram instead:

Do you see the problems? First, at least family has to stick together and she has to use geopaparazzi to share her position :-) and second I can't have her using Google Maps instead of Openstreetmaps to show me were she is. It simply doesn't work.

So I removed the send data via sms function, which was quite experimental and not used and added the Share Position function, which is now available in the maps view menu:

This will take you to the usual android sharing screen and if you select for example telegram, the OSM link to the position + marker will be sent:

And the link will bring you to:

3) Spanish localization

I am very happy to welcome on board a new translator for Spanish. That translation has been unmaintained in the last years, so I am very happy this important language is supported properly!

4) Bugfixes

Apart of the two above features, some last minute bugfixes went in:
  • zoom to track start/end not working
  • crash with enquiry on Spatialite layer with null attribute
  • GPX exports only node

As usual you will have to wait until google play throws out the version.

Enjoy and beam!!!

I am particularly excited by this announcement. HydroloGIS and GISMAP will be working together tightly to supply open source tools and training in developing countries. It is an amazing synergy for us, that will among other things push Geopaparazzi on cheap devices to do good for the people. Bringing open source tools to the people has been HydroloGIS' dream and aim since its beginning.
Thanks to GISMAP for reaching out for us in this quest.

How to properly create spatialite data for geopaparazzi

This has been asked quite some times and too often people complain about the fact that spatialite databases created in QGIS are not visible in Geopaparazzi.

I know, I also wish it was always simple and straight forward.

What I can do right now, is to show you the procedure I follow to create vector data to work with in geopaparazzi. It uses Spatialite-GUI though, not QGIS.

1) Download the Spatialite-gui

You can find it on the spatialite homepage, at the time of writing a good version for windows is version 1.7.1 available in this download area.

Open it and find yourself with:

2) Create a new empty database in which to load the shapefile data

You will be asked to save the database somewhere on disk. Once done, you should find yourself with something like this, but with different path:

3) Load the shapefile

To do so locate the Load Shapefile icon:

In this example I will import a set of shapefiles from the Natural Earth dataset, in particular the following onces:

that can be found here.

The import dialog is the important one to fill the right way:

The really important things to take care of, are underlined in red:

  1. the SRID, i.e. the EPSG code of the data projection. If that one is not right, then you will not be able to see the data in geopaparazzi. Don't even hope in miracles!
  2. the Charset Encoding. Make sure to choose the right one. For example Japanese people might want to choose SHIFT_JIS if they want to see the labels rendered properly
  3. force the creation of the spatial index
If you then the push the ok button, you should find yourself with an ok message like this after the import:

You are almost there, one last step to go.

Right-click on the database name and select the Update Layer Statistics command.

Depending on the amount of data it should keep your harddisk working for a bit. Don't think it finished unless you see a result like the following:

Once this result appears to you, you are good to go.

Move the spatialite database to your device, fire up geopaparazzi and go directly to the spatialite data view (from the mapview).

You should see something like:

Enable the countries and places layer, maybe also activate the labels for the places layer. And voila'!

This has always worked for me. I hope it will solve any issue people might have.

Geopaparazzi 4.0.1 is out: Welcome to Slovakia!

Geopaparazzi 4.0.1 has been released to google play.

This is mostly a language update release and includes Slovak as new supported language.

This is the current status of the localization effort:

Some languages need more love than others. Do you have that love to share?
Just jump on the geopaparazzi translation site.

We also hit the 10000 installs badge in google play. That is not so bad for an engineering app, right? :-)

Release note have changed place as well as the download area for those without access to google play. This is thanks to the fact that the amazing Github gives a clean and simple space to add releases with binary downloads.

And that's also quite all. Enjoy!

Geopaparazzi at FOSS4G 2014 Osaka/Tokyo

This year I have the great honor to be invided to attend and present a the FOSS4G in Osaka and Tokyo and do some research with the team of professor Venkatesh Raghavan.

There will be to mainstreams we will contribute to:


This is quite natural, since the Japanese is one of the most supportive communities to the project.

Well, we do not know all the details about the program yet, but we know for sure that apart of the talks there will be a:

Hands-on workshop:  27 Oct 2014: FOSS4G-Osaka

Code Sprint: 25 Oct 2014: FOSS4G-Osaka

I have to admit that for me as author of Geopaparazzi it is amazing to attend the first geopaparazzi code sprint in Osaka. I do love code sprints!

I know for many of you it is far, but maybe some nearby community members can come? It would be great to meet you in person and maybe discuss some future geopaparazzi features.

uDig, the Spatial Toolbox and LESTO

We will give some presentation about uDig and its Spatial Toolbox, both from a technical point of view as well as a user pooint of view.

We will also introduce the LESTO toolbox, which enables LiDAR data processing in the Spatial Toolbox.To get an idea about LESTO, have a look here.

That is all for now. But we'll keep you posted as soon as we have news.

uDig 1.4.0 on Osgeo4W + BeeGIS and the Nettools (and java 7) + 32/64bit

I have been made aware of the fact that java is outdated on Osgeo4W and that I am the maintainer. So I checked into it and noticed that I never upgraded uDig to 1.4.0 (and of which I know I am the maintainer).

Also I was told that the Nettools didn't work very well and even BeeGIS!!!

So I took the time to do a huge upgrade of everything and and very important: also added the 64 bit versions for Osgeo4W. This is almost mandatory for those that do raster data processing with uDig.

So pick your software: 32bit installer or 64bit installer.

Enjoy!!! :-)
