Which is the generic container for geometry in QGIS?
A geometry is the spatial representation of a feature. Since QGIS 2.10, QgsGeometry acts as a generic container for geometry objects. QgsGeometry is implicitly shared, so making copies of geometries is inexpensive. The geometry container class can also be stored inside a QVariant object.
How to return the oriented minimum bounding box in QGIS?
Returns an offset line at a given distance and side from an input line. Returns the oriented minimum bounding box for the geometry, which is the smallest (by area) rotated rectangle which fully encompasses the geometry.
Where is the geometry class stored in qvariant?
The geometry container class can also be stored inside a QVariant object. The actual geometry representation is stored as a QgsAbstractGeometry within the container, and can be accessed via the geometry () method or set using the setGeometry () method.
How does the densification function in QGIS work?
Densifies the geometry by adding regularly placed extra nodes inside each segment so that the maximum distance between any two nodes does not exceed the specified distance. Returns a geometry representing the points making up this geometry that do not make up other.
How does qgsgeometry create an abstract geometry object?
QgsGeometry (geom: QgsAbstractGeometry) Creates a geometry from an abstract geometry object. Ownership of geom is transferred. New in version 2.10. A geometry is the spatial representation of a feature.
How to do Delaunay triangulation in qgsgeometry?
Creates a QgsPolygonXYfrom a QPolygonF. Creates a QgsPolylineXY from a QPolygonF. Returns the Delaunay triangulation for the vertices of the geometry. Deletes a ring in polygon or multipolygon. Returns a copy of the geometry which has been densified by adding the specified number of extra nodes within each segment of the geometry.
What’s the change log for QGIS 2.0?
Change log for the next release of QGIS 2.2.0. The emphasis on this release has been very much on polish and performance – we have added many new features, tweaks and enhancements to make the user interface more consistent and professional looking (and hopefully easier to use).
When does the next version of QGIS come out?
The current Long Term Release (LTR) remains version 2.14.x. This release provides incremental improvements over our previous release. The majority of activity is currently focussed towards the development of QGIS 3.0 which is our next generation release planned for the end of the first quarter of 2017.
Which is the best alternative to ArcGIS for Linux?
For many people, discovering QGIS is the end of their search for an ArcGIS alternative. It has a clean interface, it’s easy to use, and it just works. QGIS supports a wide variety of raster and vector formats, and if you’re a Linux user, there’s a good chance that it’s already packaged for your distribution’s default repositories.
How to use qgsfeature-QGIS in Windows 10?
approximateMemoryUsage Returns the approximate RAM usage of the attribute Lookup attribute value by attribute name attributeCount Returns the number of attributes attache attributes Returns the feature’s attributes. clearGeometry Removes any geometry associated with the
How to write Python console in qgis.core?
I write python console in qgis: It gives the path and I paste them into PYTHONPATH and PATH. That’s it! Not the answer you’re looking for?
Where is Python-qgis.bat in Windows 10?
I’ve just been wrestling with a similar problem, and noticed a batch file in the OSGeo4W\\bin folder called python-qgis.bat. This is part of an OSGeo4W package based install of QGIS 2.18.15 x64 on Windows 10. When executed, this batch file opens the Python interpreter. import qgis successfully runs from within.
