@yoyonel ,
here is an article about some basic optimization.
http://www.opengis.ch/2015/04/29/performance-for-mass-updating-features-on-layers/

Maybe we could use something like that to group our auto-save rectangles, so as to not use several undos/redos.

@yoyonel :
the script is in
interactive_map_tracking.wiki/Videos/audio_script_for_video.txt
There is not much time to speak, the video is already quit packed

Useful to localize the current position on QGIS and iTowns maps/3d view
TODO: add orientation informations

The problem comes from our current approach to refresh the map (epsilon zoom on MapCanvas) that provoke a canvaxextentChanged and launch the tracking.
To avoid this, i add a filter on the actual extent (to save) and the last committed.
If layers are different (with a proper epsilon value), we continue the tracking process else we cancel the tracking.

To reproduce :

• create a tracking shapefile in WGS84 (4326)
• track some geometry
• set threshold to 1
• track more
• change shapefile SRS to IGNF:LAMB93
• track
  --> produce the error message

error is :
``Traceback (most recent call last):

Hey @yoyonel , a small bug , but very important (it negates all the work on V2 ! )
the log for web related GUI is not concerned by main switch.
It appears in the Main loggin tab, the log chekc box being crossed or not.
Example of log :

2015-03-03T21:44:58 1   ### width : 1080 - height : 768
2015-03-03T21:45:00 1   ## Tab : About
2015-03-03T21:45:00 1   #last_state : 1
2015-03-03T21:45:00 1   ## WebView : OK
2015-03-03T21:45:00 1   ### width : 1024 - height : 768

Small enhancement :

• is it possible to change default scale to 1:300 instead of 1:200?
• is it possible to display default as 1:300 instead of 300 (confusing)

@yoyonel , here is what I found to use javascript in QWebView

QWebView.evaluateJavaScript(..)
QWebSettings::clearMemoryCaches() 

how to reproduce :

• start tracking a postgis layer
• select a set of tracked camera
• try to update the user_id field of the selected camera
• it will do nothing
• now the tracking is supposed to be activated, but it does nothing (more exactly, it tries to do something, but nothing happen)
• More important, even saving/closing qgis won't solve the problem, we have to add the tracking layer again to start fresh

This is a simple enhancement.

Hey,
this is the thread dedicated to dev of a new mechanism to group saving of camera position.

Add a demo to illustrate how the hexagonal grid can be automatically updated when there is a new tracking position

BUG :
when offline, rapidly switching from one tab to the oter mutliple times starts an infinite loop,

Careful merge of both branches when the issues #18 and #19 are closed
Careful because we want clean history

@yoyonel Small label:enhancement :
when setting the threshold to 1:400,
going to exactly 1:400 doesn't track (I guess because it is < instead of <=)

@yoyonel : we need to close #19 before (that is defaulting to V2 = async)

Proposition of improvement, it is clearly a non necessary stuff, but it could be a cool trick to know for you @yoyonel .
the main page of doc (User guide) includes a youtube video, in flash.
Currently, the plugin GUI doesn't display it.
It would be super cool to have video in plugin,
and it seems to be feasible :

QWebSettings().PluginsEnabled = True

@yoyonel The idea is to use the zoom level (aka scale) rather than a fixed meter size as a threshold.

• it makes more sense for geographical-oriented people
• it is simpler to explain
• it is perfectly independent of srs

It could solve our problem in #7 and #8

This is an enhancement for Develop v2 version of tracking.
The tracking is asynchronous, but was doing a lot of function calls.
By reducing this we can gain speed and efficiency.

Small cosmetic changes :

• v2 by default activated, change name for "Asynchronous tracking commit (smoooth)"
• Add 2 tabs :
  • Tab "About", with correct credit
  • Tab "User Doc", displaying basic html with images (simplified "User Guide" of our wiki)

Work dispatchment :

• @yoyonel GUI change in code
• @yoyonel Check that is it is possible to display simple html in the User doc
  then
• @Remi-C write simplified UserGuide in html, with images

Here is the error
Simply zoom in to reproduce

@yoyonel Sorry, Traffi Polu can't stay permanently here.
It needs to have its own plugin.

Adding the conflict detection, changing the illustration for hex grid

The time written in database is not precise enough.
Its precision is second, it should be milliseconds.

Having second is dangerous because many w_time are identical.
@yoyonel can you look into it to check weither it can be done before milestone Release?

This is a pure enhancement,
for futur realease.

The idea is that starting from 2.8, it is possible to create in memory vector layer.
Now it could be very useful to propose to the user to directly create a tracking layer with correct user_id and w_time, so it would be a one click operation to start tracking in a mono-user mode.

Add both sponsor (Terramobilita and ?)
@yoyonel : I don't know the name of the other one

Refactor code
Section : Signals Manager

Help to :

• clean code
• increase robustness
• increase readability (for comprehension, help debug, ...)

anooying, change .gitignore and rm files

A strange error message, when launching qgis from terminal in gnome.
The message is printed when we click on plugin icone

Warning: QDialog::exec: Recursive call detected

todo :
more illustration
explaining GUI parameter
give sql script for postgis enthusiast

To reproduce :
create a shapefile of type polygon with user_id::text and w_time::text
Set the shapefile srs to 4326 (WGS84).
WGS84 unit is not meter but degree.

Setting the threshold to 1 or 0.1 or 0,1 slow down conserably the plugin,
finally freezing qgis with one CPU fully occuped.

To reproduce : use a shapefile for tracking, track some
then try to remove tracking layer from qgis (Ctrl D)
It crashes QGIS

@yoyonel : the plugin has been reported to not install well from QGIS plugin repository,
with plug version 2.8.

branch Develop
CRITICAL :
when having 2 possible layers for tracking (one shape, one PostGIS)
We can select the correct layer in the list.
In the log it correctly show the selected layer.
BUT : the update happen to first layer

@yoyonel I solved it, I'm directly put the ocrrect code in the init function, which is both ugly and not a good idea.
Can you check the commit to see how you can adapt this to your code style?

Same 'spirit ' than # 43
Some works for extract Auto -Save feature and lighten the labor component script file ( interactiv_map_tracking.py )
This work/issue help end to increase readability and robustness

And not resizable. See attached pics. Font size in the second image too small.

...

The dev doc should be at a minimum level before releasing to first version milestone@"Release 1.0"
This include

• a little bit of high level dev doc (principle of each feature implementation, pointer to most important functions)
• a little bit of issue specific doc, that is explain what was tried but unsuccessful.

On Win or Linux :
the memory consumption is increasing when swithcing between tabs.
To reproduce :

• go in the doc tab
• note qgiis memory usage
• click on video , this will open youtube
• note qgis memory usage
• switch tab, open again the doc tab
• note the qgis memory usage

It seems that some of the memory is cleaned, but not all of it.
Maybe there is a cache mechanism in QWebViewer

Need to fix/clean this feature.
Many bugs and misunderstoodings in this part.
I have (now) a good idea about this tool, i can clean and produce a good implementation :-D

todo :

• propose out of the box demo for both, to help people wisualize and try it
• create a wiki page per demi, with screenshots

We use ann arcanic way, very unsafe because we write manually the name of the plugin. Yet, an user would name the plugin folder the way he wants!

there is a simple solution : use self.plugin_dir

@yoyonel Can't read the layer name in the second tab.
Annoying !
