           | 
           | Author here! I take pride in crediting OSM, so it is on
           | multiple places. There even is an entire explanation on why
           | OSM rocks under the 'copyright' tab. It's gonna move soon to

       | I studied geography for about eight years in university and
       | something that drove me kinda mad is how cartographic authoring

       | (I once had a short rant over dinner with the President of ESRI
       | Canada about how my GPU is built for rendering geometries and
       | ArcGIS ignores its existence).
       | 
       | On the surface, the CAD pedigree makes sense. But... why aren't
       | more tools like video games? Make it super easy for anyone to
       | start getting involved.
       | 
       | I remember all the gatekeeping-like discussion in "Public
       | Participation GIS" seminars: you've gotta be an expert to author
       | good data because there's so many ways to do it wrong. Blah. No.
       | 
       | One of my daydreams if I get FU money is to make an incredibly
       | user friendly set of web based analytical GIS tools. Not just the
       | basics like buffering and queries, but the entire spatial toolbox
       | to build data processing pipelines. I want a layperson to be able
       | to ask "where should I buy a house if I care about these four
       | parameters?" (and for it to not be a hidden magic purpose built
       | portal on some realtor website)
       | 
       | The immediate retort from my internal pessimist is "the data
       | isn't available or isn't consistent" but I don't buy that
       | anymore. I remember having to go ask nicely to obtain shapefiles
       | from my city. Decades later it's all just online. And the
       | community can help catalog data sources, add metadata about
       | transforming them to standard schemas, and sharing data pipelines
       | with the community in some sort of catalog.
       | 
       | I really think it's a UX problem above all else.

         | A root cause of the problem you've identified is that the tools
         | are designed to offer first-class support for cartographic
         | applications that pre-date the use of computers. Almost none of
         | this has any relevance to modern geospatial analytics but it
         | pervades the way the software works. Users that just want to
         | build a modern analytic application are still forced to deal
         | with this legacy baggage even though it provides no value to
         | them and often makes their applications worse. The learning
         | curve is unnecessarily steep.
         | 
         | Like you, I am of the opinion that a new set of GIS tools that
         | focus solely on the needs of modern geospatial analysis users
         | would be amazing.
         | 
         | Another gap is that cartographic tools have a deep assumption
         | that geometry does not move. They don't provide support for
         | correctly reasoning about spatiotemporal relationships, which
         | are pretty important in modern geospatial applications.

         | A lot of this data exists, and is freely available.
         | 
         | I used to work for a startup where we tried to accurately
         | predict the amount of sun a particular plot of land would get.
         | You can pretty much get a 3d map of the world with 5m accuracy
         | (or even more granular, but the datasets get ridiculously big
         | at that point), then render a 360deg view from any location in
         | the world and simulate the sun movement. You can even get 3d
         | models of some cities to take buildings into account (the earth
         | model is ground only). The startup eventually failed for Covid
         | reasons.
         | 
         | Satellite data is available for most of the world for things
         | like wind speed, cloudiness, vegetation, ...
         | 
         | If you live in a decent country you may be able to freely get
         | data for zoning, power lines, internet, building density,
         | public transport...
         | 
         | You can build a really good dataset to evaluate a particular
         | plot of land if you combine all this data.

           | Related, maybe OT, but you seem a person that knows a lot
           | more about this than I would know: more exactly I wanted to
           | ask you if you know of a decent enough method to get the
           | height of a building based on GoogleStreetView.
           | 
           | Meaning, I'm "inside" GoogleStreetView, I'm looking at a
           | "building" from outside on the street, I know the geo
           | coordinates of the camera that took the photo, I know the geo
           | coordinates of the building, so that I know the distance
           | between the photo camera and the building, I can "count" (for
           | lack of a better word) the building's size in screen pixels
           | (or some other unit/reference? which one?), and based on all
           | that I'm curious if one can get the real height in meters of
           | said building.
           | 
           | From what I could found around on some other forums there
           | were people mentioning the aperture of the GoogleStreetView
           | photo camera being part of the "equation" to compute it all,
           | and that would be a problem because we do not know the values
           | for the aperture. I have no idea though if all that
           | discussion was on the subject or not.
