Georeferencing a Scanned Topographic Map using QGIS

[@praiseborngreat3320]

Your lectures are clear and explanatory. Thank you for all you do.

[@geodeltalabs]

You are welcome :)

[@PrasadPLVK]

I love your way of explanation and your vocabulary

[@Official-ge3gc]

Thank you so much for this interesting and significance video!

[@abdulsalamusman1948]

So impressive. More progress

[@geomastersinsights]

Very informative tutorials.

[@isaacnzayisenga1189]

Wonderful Lecturer, you're important to me. In the coming videos if possible, you can help us how to records spatial data of an area using GPS and how to enter those data in ArcGIS for making a map of that area. Thanks in advance for your time and support to us. Isaac Shepherd Kigali-Rwanda

Thanks for the information, if any auto processing is there?

[@JackyVSO]

Thanks for the tutorial! When I try this on a different map from the same source, the topographical map is consistently about 0,1 km too far North. What could be possible reasons for this? I entered 9 mostly evenly spaced points by zooming and clicking on the grid on the map.

If I decide to import a shape with a different CRS, do I need to transform the new shapefile to the current CRS?

[@geodeltalabs]

When you import a new shapefile with a different CRS, the on-the-fly projection will kick in and the imported shapefile will get transformed automatically to the CRS of the project. However, this does not mean that the original CRS properties of the shapefile changed, as it's only a temporary transformation.

Hi sir thank you so much, i learnt lot from your videos Sir i have dout please Help me.., how georeference a kml and DWG files in qgis rather than png and jpg files How to Align in qgis as we do in autocadd

[@tubuobaggio]

Is it possible to teach us the basics in creating geoprocessing tools using python (Jupiter Notebook), that will be very helpful thanks very much

[@ΜακηςΣακετας]

The topo map of Nicosia for example are like two maps combined together, so I think this technique cannot be used. Also in Tactical Pilotage maps there are problems in their georeference.

[@ananyag7978]

In the georeferencer window, the Mean Error shows 2.59.. What does this mean? is it in meters or feet?

how to get lat,long coordinates corresponding to the image map

[@geodeltalabs]

One of the easiest ways to do that would be to first create a point shapefile marking the points for which you would need the coordinates. After that you can add two new fields and calculate the lat and lon values using the field calculator
