I have a shapefile from an external source. I cannot select a certian polygon. As shown in the attached picture. Any ideas how to see what the problem is?

When I try to upload the controlDict folder into Paraview, it is inconsistent in terms of display. At times, like the picture shown below, I can only view the image of the model at that particular size and if I try to drag it out, there seems to be an imaginary bounding box around it then prevents me from viewing the model. I am currently using WSL to learn how to use openFOAM and this is a tutorial that I followed along regarding flow in an elbow. I’d like help regarding this matter.
I was following through a tutorial online and I expected to see the model fill the screen but to my surprise, there was an imaginary bounding box that limited my ability to render it as senter image description hereeen from the screenshots below. enter image description here
the data annotation company I am working at is using MS-Paint to make red bounding boxes around the objects in the images.
The problem is it takes a lot of time to open each image individually on MS-Paint and then creating a boxes around the objects. Is there a tool that can open multiple images at once like Lightroom so that I can just open the images and navigate through them while creating red bounding boxes.
There are a lot of annotation tools out there but I was not able to find a suitable solution. If someone has good experience on data annotation please help
Steps that I am doing right now:
Open a single image on Paint
Identify the object in the image
Change the file name to the name of the object that I identified
Save the file
You could try the following tools for image annotation.
VGG Image Annotator (VIA)
LabelMe
cvat
LabelImg
VoTT
All are open source projects.
So I am trying to create an atlas using QGIS and I am trying to create a shape that is unique to a single page (the red circle). Naturally, it should show up on the other pages as well. I want it to display only on one page, or better yet, I just want it on a few selected pages. Is this possible? Thanks in advance!
So my problem is, that I have a tileset which geometries are Multipolygons and when I want to display the district names it places multiple labels instead of just one centered. Is there a way to fix this?
Here is a screenshot for clarification
The data comes from a postgis database, I just export it to a CSV and upload it to mapbox.
I have tried converting the Multipolygon into single Polygons but that ended in the same result.
I also played around with the text padding in mapbox studio but with this option the label placement is very off.
Is there possibly a way trough Mapbox GL JS to fix this issue?
You need to generate a separate label layer. You can use geojson-polygon-labels to do this.
I was wondering if it was possible to overlay an icon marker over a geometry object in Open Street Maps. I am using gwt-openlayers which is a java wrapped version of the open layers api with an Open Street Map tile server in Eclipse. If anyone has any knowledge about this I'd greatly appreciate it.
Thanks,
Matt
You can if these geometric objects are points by using the externalGraphic property which is a URL of the image.
If you need to overlay them on top of a polygon just create an ImageOverlay on top of the center of the polygon.
I have it figured out. I am just making two different layers, one for the markers and one for the geometry figures. I am overlaying the markers over the geometry figures by adding the markers to the top of the layer list.
