I currently have a group of users counting objects in a satellite image.
To ensure viewing conditions are the same for each user, I want each user to view the image the same. In other words, I want each user to have the same display.
To do this, I have asked each user to zoom to the same scale (e.g., 1:1,000) and have created a fishnet of polygons. Each user selects a fishnet polygon and zooms to the set scale. However, the display appears different even when using the same scale. Some users are more "zoomed in" and others are more "zoomed out" despite setting the same scale.
All users are working on the exact same satellite image (0.5 m Worldview Imagery). However, some users are using ArcGIS Pro, Arcmap and others QGIS. The laptops being used are also different. Even amongst the ArcGIS users, setting the same scale does not result in the same display.
