    The amount of content I've added to Null Island over the years....

      yes! me too. it must be piled high with garbage data.

    I love the phrase "It doesn't know it's a map, it doesn't know where it belongs." That just sums up georeferencing perfectly!
    More importantly, though, I have to ask - now that you've taken the effort to georeference, did you share it back with the original image provider so that everyone can benefit?? The thought of people georeferencing the same maps over and over again unnecessarily is painful!

      right?! and GIS software doesn't know its making a map. it's just a compiled bunch of code. the magic happens in our minds.
      no, i didn't send the georeferenced image back to Tom, but i did think about it.

    Cool video ! For the next vid, can you show how to make a 3D looking world map by adding DEM from SRTM? I used 'vertical exaggeration' function in a global scene mode, but it doesn't fully show the all the details when the map's zoomed out.

      i think you might be referring to the nature of ArcGIS Pro to reduce 3D detail when zoomed out. it does this for performance reasons. one trick i do is to make a really big layout, add my 3D map to that, then when i export the image i get a bit more detail.

    Thanks John for such informative videos
    I want to ask you that I want to create vector tile package I have data both dem and polygon I want to show terrain or hillshade effect in shape file(polygon) an then create vector tile package how I can do this.
    Please help me out
    Really appreciate your help.

      Ah what a fun project! Yes you can do this but you will need to use the "reclassify" tool to create a discrete chunky version of your hillshade imagery, then use the "raster to polygon" tool to convert the image into vector polygons. You might find that if the resulting polygons are too detailed and high-resolution, then you can, before your first step, run a "statistics" raster function on your hillshade image to blur it before doing the reclassification.
      This blog post describes a slightly different goal, but parts of it may be helpful to you: www.esri.com/arcgis-blog/products/arcgis-pro/mapping/chevalier-shade/
