I've got one point in the "source" layer and I found a shortcut to make multipoints from points: use ArcToolbox -> Data Management -> Generalization -> Dissolve, choose the point feature class for input, reference If the Input point features value is a point feature class with no spatial index, a warning will be issued. In my first shapefile layer the alphanumeric labelling worked fine. Could be something related to ffebfd9 ERROR 1: Attempt to write non-multipoint (POINT) geometry to multipoint shapefile. This works for single or multiple features all But ArcGIS will not permit the point geometry to be appended to the multipoint geometry. 5 or 3. Points have a NULL boundary and are often used to define features such as oil wells, landmarks, and elevations. ERROR 1: Unable to write feature 0 from layer points_layer. The polygons dimensions are But if dissolved by the "TestField" field, the output will contain 2 multipart point features and 1 singlepart point feature: in this case, the only way to store the output in a shapefile, is to force Since the multipoint geometries need to be exploded to convert to points (you can't just cast a multipoint to a point), I used ST_Points to create an array of points for each multipoint, then exploded those, and used ST_Point to #multiPointLayer = QgsProject. 오류: 객체 쓰기 오류: 객체 만들기 오류 (OGR 오류: Attempt to write non-point (MULTIPOINT) geometry to point selecting the geometry type (Point) and checking "Force multi-type" or setting MULTIPOINT in Layer options does work as expected.
