Visual Changelog

Version 1.2
Added menu option to export all maps as image files.


Fixes:

select Temporal Profile / Spectral Profile button activates the required map tools (#91).
map canvas context menu "copy to clipboard" options (#92).


Version 1.1
Time Series data sources are shown in a tree view, which improves the overview in case multiple source images exists per observation date.
Observation dates of visible Map Canvases are highlighted in the time series tree view.

Fixes:

Sensor raster layer properties can be opened from MapView layer tree (#87). Stats will be related to center mapcanvas.
StackedInputDialog, MapCanvas context menu, "Save Changes?" labeling dialog (#85),
remove temporal profile (#86), draw new feature error (#84), Crosshair button status (#90), and some more


Version 1.0

Map Canvas Context Menu
The map canvas context menu has been re-organized and enhanced by:


zooming to single map layers
open the properties of single map layers
the "Set Quick Labels" button (see next feature)


Quick Labeling
The map canvas menu entry "Set Quick Labels" can be used to write sensor/product, file and observations-date specific information
into attribute fields of linked vector layers.


open the layer properties of the vector layer you like to label


edit the form attributes and use the EOTS Quick Label form to each layer fields, that you like to
label automatically.


Each map canvas relates to a raster timeseries sensor/product and observation date. From that we can derive the following label information:

Labeling Dock
The Labeling panel can be used to modify vector layers. The editing process is similar to that known from the QGIS
attribute tables.

Use the labeling panels combobox to select the vector layer you like to modify
Press the "Start Editing" button
Make your changes
Save your edits or reject them


Toolbar

Old toolbar

New toolbar
The toolbar was enhanced with an button to import vector sources, to select, add and save vector features, and to synchronize
the map canvas center with that of the QGIS main map canvas.


Map Views

The map view control panel has been reorganized based on the [QToolBox](https://doc.qt.io/qt-5/qtoolbox.html#details) widget.
This way fix a couple of layout issues, where map view settings looked squeezed. Each
Map View has now its own map layer tree to specify map layer visibility.

Time Series Model

The multi-sensor time series allows to add multiple images with same sensor properties and observation date.

Version 0.8

increased version to 0.8
added labeling panel
scheduled map canvas refreshes
multiple images per observationdata & sensor
fixed several bugs
uses QgsTaskManager for background loading
own QgsMapLayerStore to not mix-up with (main) QGIS layers


Version 0.7

Visualization of images with stacked temporal information (each band = one observation date)
Speclib I/O as CSV or ENVI-Spectral Library + CSV table for attributes
temporary VRTs now created in-memory (gdal VSI mechanism) instead in a disk temp path


fixed bugs:


Spectral Library: profile coordinate now in center of map pixel (issue #66)
Save map canvas to clipboard
Width of plot lines now scale-independent (issue #64, QPen.setCosmetic(True))
adding fields to spectral library (issue #61)


Version 0.6

SpectralLibrary Module

now based on in-memory QgsVectorLayer
Locations and values of spectral profile can be exported as vector data set
Locations of spectral profiles can be rendered on MapCanvases


Temporal Profile Module

now based on in-memory QgsVectorLayer
Locations of temporal profiles can be exported as vector data set
Band values of temporal profiles can be exported as CSV file
Locations of temporal profiles can be rendered on MapCanvases
several bug fixes


Version 0.5 and before

increased version to 0.5
ported to QGIS 3, Qt5 and Python 3.6
improvements in temporal profile visualization
removed several bug
visibility of vector and raster layers can be toggled per map view
improved interaction between QGIS and EOTSV (Buttons to import/export spatial extent of map canvas or center)

2018-03-29
- improved definition of individual 2D / 3D charts per sensor & pixel-location
- added based OpenGL based 3D plot features (axis, grids, labels)
- changed name to "EO Time Series Viewer" (EOTSV)

2018-02-11


merged updates to temporal profile visualization, e.g.
save temporal profiles, compare 2D profiles between different location, experimental 3D visualization


2018-01-31


added file filters for OpenFileDialog


2018-01-19


initialized Sphinx-based documentation
improved map visualization + map settings


2017-05-21:


many changes, done in development branch "develop",
e.g: QGIS MapCanvases for interactive maps, temporal profiles, ...


2017-02-14:


first setup for test users in the recent development branch
