Introduction: This guide provides step-by-step instructions to produce drive-time isochrones using a single vector shapefile. I get what you're saying but the version you put (using "x" rather than "xmin") is no more obvious than the version that is currently in use because you still have the whole "centroid(geometry)" part. Just point and click on the features that you wish to add to the selection. A shapefile is an Esri vector data storage format for storing the location, shape, and attributes of geographic features. These are the points falling in the UTM Zone we specified in the expression. For example, features can be single part or multipart, can have 3D vertices, can have linear measures (called m-values), and can contain parametrically defined curves. I used the 'Densify by Count' algorithm to add 10 points on each line feature. For example, the three types of vectors are points, polylines and polygons. Show or Unshow Vertices 2. Included in this installer is sample data for the Eastern Cape and South Africa. Shapefiles often contain large features with a lot of associated data and historically have been used in GIS desktop applications such as ArcMap. After, it was applied the qgis:multiparttosingleparts algorithm, and this single feature was broken at the vertices, so that we may have multiple features of single line. Under the options, select export, and export out to a geodatabase table or dbf.
