In this lesson I will show you how to split a polygon into several polygons using lines from another layer You will learn how to • Install the digitizing tools plug-in ... QGIS : create map using vector data model(points,lines,polygons) create map using vector data model(points,lines...
I understand how to create the border, but not how to generate these polygons inside the first one. I think I am down to use the "model" and the PyQGIS parts of QGIS but I don't know where to begin. I think I also have an optimisation issue about this problem. qgis pyqgis polyg...

Make sure you take full advantage of QGIS plugins. Whether you’re looking to build web maps or performremote sensing classification, QGIS plugins can boost its functionality. Adding a basemap in QGIS Basemaps are background, non-editable, georeferenced images that give a point of reference on ...
QGIS : Want to create "polygons with hole" instead of "overlaping polygons" when use of "contour tool" Are my basic implemetations of AES-CBC and AES-GCM in PHP secure? Could rocket exhaust eventually lead to detrimental effects from interplanetary space pollution? ...
Polygon from Periodic Tiling Intuitions in philosophy, boon or bane? Turning off camera while it’s still writing images to SD card? What difference does cooling stuffing make, before roasting a bird? Non-attacking “brooks” on a periodic chess board Is this web-site a Z...
Unfortunately, Mathematica doesn't provide a way to set a tolerance in RegionUnion, otherwise I would have just union'd all the polygons to begin with. To fix this I can rasterize the graphics first at a very high resolution and then use ImageMesh: gr = Rasterize[ Graphics[{White, ...
The API also offers the possibility of adding information to these images, such as a marker at a specified position or drawing a line or a polygon on the map.3.2. How to make a map image with markersTo add markers to a map image, a parameter called markers must be used in th...
We introduced a brand new feature in GIS Cloud Mobile Data Collection app – Line & Polygon collection! In this post we are going to explain how to set up a line collecting project and highlight options and tools that can be useful for your field collection project. Line collection in the...
1. Import the spatial data to QGIS To create a selection with an expression, first open your dataset in QGIS. 1. Open QGIS 2. From the menu bar choose Layer → Add Layer → Add Vector Layer 3. Navigate to your shapefile and add the dataset by selecting the .shp component of the dat...
