This implements a new "import geotagged photos" algorithm
for processing. It allows selection of a folder which it
will scan for jpg files which have been geotagged and
creates a PointZ layer with the result, with attributes
for photo path, altitude, direction and timestamp.
Optionally the scan can be recursive and you can create
an optional table of photos which could not be read
or which were missing geotags.
The algorithm automatically sets the output table to
use an external resource widget to display the linked
photos in the attribute form.
[ALGCHANGE]
Adds two new algorithms which expose QgsGeometry's methods
for segmentizing curved geometries.
"Segmentize by maximum distance":
The segmentization is performed by specifying the maximum
allowed offset distance between the original curve and the
segmentized representation.
"Segmentize by maximum angle":
The segmentization is performed by specifying the maximum
allowed radius angle between vertices on the straightened
geometry (e.g the angle of the arc created from the
original arc center to consective output vertices on the
linearized geometry).
Projects points from an input point layer by a specified distance
and bearing (azimuth). Supports dynamic parameters for the distance
and bearing so that they can use field values or expressions.
And implement some fixes/improvements (refs discussion on the dev mailing list):
- allow user to specify created field name
- allow optional creation of a summary table showing new class value vs original
value
Removes duplicate nodes from the geometry, wherever removing the
nodes does not result in a degenerate geometry.
By default, z values are not considered when detecting duplicate
nodes. E.g. two nodes with the same x and y coordinate but
different z values will still be considered duplicate and one
will be removed. If useZValues is true, then the z values are
also tested and nodes with the same x and y but different z
will be maintained.
Note that duplicate nodes are not tested between different
parts of a multipart geometry. E.g. a multipoint geometry
with overlapping points will not be changed by this method.
The function will return true if nodes were removed, or false
if no duplicate nodes were found.
Includes unit tests and a processing algorithm which exposes
this functionality.
This algorithm assigns a new projection to a vector layer.
It creates a new layer with the exact same features and
geometries as the input one, but assigned to a new CRS.
E.g. the geometries are not reprojected, they are just
assigned to a different CRS.
This algorithm can be used to repair layers which have
been assigned an incorrect projection.
