My initial thought is that your project settings are not in the correct coordinate system, regardless of the layer settings. I would start a blank project and only import a single layer and that is already set at the Hartebeeshoek94 projection. I'm not sure if QGIS takes the projection of the first layer, so maybe right click the layer and choose 'Set ...

Assuming you are talking about a map of the world in Mercator Projection, Something like this: Then You should know that not all pixels will represent the same area. There is a large amount of distortion as you go towards the poles, the area represented by each pixel will decrease as you go towards either Pole. Tissot's indicatrices show a good visual ...

If you want just the label: // add a scale at at your map. var scale = L.control.scale().addTo(map); // Get the label. var metres = scale._getRoundNum(map.containerPointToLatLng([0, map.getSize().y / 2 ]).distanceTo( map.containerPointToLatLng([scale.options.maxWidth,map.getSize().y / 2 ]))) label = metres < 1000 ? metres + ' m' : (metres / 1000) + ' ...

You can get the current zoom level using getZoom(). Assuming that you're using the tile layer system as used by Google Maps, Bing, Open Street Map and Esri, you can use that to infer the scale - see What ratio scales do Google Maps zoom levels correspond to? If you're not using that tile system, you may need to find another way to infer the scale from the ...

If you want to digitize at that Map scale at 35,000, just remember that when someone zooms it in further , the line will be a bit shift, so I would recommend to zoom around 12,000 or lower then this way your digitize will be more precise than at the 35,000. So will your project be just a small local area or whole wide area ?

If you can make shure, that your map scale will not change to a larger scale then it would be sufficient if you digitize your roads in 1:35000. Be aware that this can be a generalization in some situations (very curved road network). If in the future your road data will be needed for larger scaled maps, consider digitizing at at larger scale. Consider the ...
