How to get the coordinates of a field in QGIS?
Therefore, the coordinate list for every field is very long. With these coordinates, we would like to create polygons in QGIS to e.g. determine the size of fields. Unfortunately, the coordinates can only be extracted in one cell of an excel file. This looks like this:
Is there a GPS plugin that works with QGIS?
Version 1.2.3 of GPSBabel is known to work with QGIS, but you should be able to use later versions without any problems. To import GPS data from a file that is not a GPX file, you use the tool Import other file in the GPS Tools dialog.
Which is the GPX format used in QGIS?
The format that QGIS uses is called GPX (GPS eXchange format), which is a standard interchange format that can contain any number of waypoints, routes and tracks in the same file. To load a GPX file, you first need to load the plugin. Plugins ‣ Plugin Manager… opens the Plugin Manager Dialog.
Can you export a polygon shapefile to GPX?
No, the GPX driver of GDAL which is used by Qgis for Save As does not know how to handle polygon geometries, and throws an error. But you can convert the polygon into a line geometry using Vector->Geometry-Tools->Polygon to line, and export the resulting new shapefile to GPX.
How to get the centroid of a polygon in QGIS?
With default behaviour in QGIS the first column in excel will then be a Well Known Text representation of the geometry. If you just want the centroid of each polygon, you can use the command: That will return a WKT point with the centroid, ie. Point (34245423,4565645).
How to display the name of a polygon in Excel?
I would like the attribute table to display the name of the polygon (ex. address) and then the coordinates of the nodes (ex. nodeA= Ax and Ay, NodeB Bx and By, NodeC Cx and Cy, NodeD Dx and Dy) is there a easy way to create all the needed polygons and then have the coordiends of the nodes displayed in the attribute table? any help would be great!!
How to import a CSV file into QGIS?
At least in OpenOffice Calc. Then you can save it as a CSV file and import it into QGIS using the delimited text import (and selecting WKT for the geometry). You may run into issues with the polygons being invalid as the first and last points should be the same, in that case use:
Which is the standard vector file format for QGIS?
The standard vector file format used in QGIS is the ESRI shapefile. Support is provided by the OGR Simple Feature Library (http://www.gdal.org/ogr/). A shapefile actually consists of several files. The following three are required:
How does a shapefile get loaded into QGIS?
Selecting a shapefile from the list and clicking [Open] loads it into QGIS. Figure_vector_3 shows QGIS after loading the alaska.shp file. When you add a layer to the map, it is assigned a random color. When adding more than one layer at a time, different colors are assigned to each layer.
How to export polygon shapefile with coordinates in Excel?
You may open your layer in tabular form (press F6) and copy-paste (Ctrl+A, Ctrl+C, Ctrl+V) all features into excel. There (usually, in the first column) you might notice your geometries in WKT (well-known text) format – every vertex is shown in form of decimal degree coordinates.
How to create a polygon using latitude and longitude?
I am using QGIS 3.2 and I need to create an area to form a polygon shapefile using latitude and longitude, not using Python as I am just a beginner. How to do this?
