Mapping for One-Place Studies - a forum

Kepler.gl (originally from Uber) is "a powerful open source geospatial analysis tool for large-scale data sets."

I know of two ways to georeference a map for free:

1. On your computer using QGIS Open source software.
There is a lot of information about QGIS, including:

• in this forum
• my own working instructions for georeferencing
• the official tutorial on georeferencing
• this tutorial from QGIS tutorials on georeferencing

QGIS is very powerful and has many functions besides georeferencing but may be daunting for someone just wanting something simple.

2. Online using the free Map Warper Georeferencing application from Tim Waters
There is a brief Map Warper Guide, but it is a fairly simple process. I have not tried this fully yet.

Bear in mind that once a map has been georeferenced it still needs to be tiled before uploading to the web for use. I have MapTiler software that can do this.

To create a Modifiable Feature Layer (MFL) go to your OPS in M4OPS and then:

• under Advanced Options click on the MFL tab
• click on New - this will create a new blank Modifiable Feature Layer (MFL), and open some more buttons
• click in the MFL name box and enter a name by which this Modifiable Feature Layer (MFL) will be known
• in most cases leave the Fields dropdown as "Minimal Fields" (explained later)
• now for each feature you want to create:
  • depending on the feature you want to create, click on the Point, Line or Polygon button (the only difference between a Line and Polygon is that the first and last points of a Polygon are joined up
  • (note you can change everything later, so it is much better to start with just an approximate Point, or a simple Line or Polygon, in approximately the right area)
  • on the map, click where you want your first point
  • for a Line or Polygon, you now need to:
    • click on further places on the map to create vertices (points on the Line or Polygon which are automatically joined up)
    • double click to create the last vertex and indicate you have finished
  • having finished the "geometry" of the feature, you will be shown a little form where you can enter its "short text" and "description" (these are  the Minimal Fields mentioned above) - use this to name and describe the feature
  • click on Save to save these fields, then Close to close the little form
• click where you want your next feature etc, again enter its  "short text", Save and Close the little form
• repeat as often as you want (but bearing in mind that this is a prototype, do not spend too long entering large amounts of data as it might all disappear)
• at any point click on the main Save button to save this Modifiable Feature Layer (MFL) in M4OPS (you can do this as many times as you want)
• later, if you wish to move the positions of any of the points (or vertices on a Line or Polygon) then click on Move, and then click and drag the points to exactly where you want them
• if you click and drag any point on a Line or Polygon this creates a new vertex - and they can therefore be made as complex as you wish
• to delete any point (or vertex on a Line or Polygon) then click on Move, and double-click on the point
• if you wish to enter, or change, the properties (fields) of any points, or to change the type of geometry (point, line, polygon) of any of the features, then click on Alter and fill in the form - remembering to Save the form before you Close it
• when you have finished with this MFL click on the Close button, and all the extra buttons will disappear
• to look at, add to, or modify your MFL simply click on the MFL tab and select your saved MFL from the dropdown - and then continue as above, making sure you save the MFL when you have down any changes

When you are happy with the details of your features (particularly their "geometry" ie where they are and their shapes) discuss with Peter what to do with it.

OpenAddresses.io is "The free and open global address collection." Anyone can Parse & import into a database, put on a map, or use for geocoding.

Some countries (eg France) are much better covered than others (eg UK).

Morphology is "an exploratory cartographic tool based on the Mapzen platform that eschews common communicative elements like color and symbols. Instead, it seeks to show the world, and all its constituent parts, as a series of carefully chosen lines."

The “True Size” Maps Shows You the Real Size of Every Country (and Will Change Your Mental Picture of the World).

The True Size is "a website that lets you compare the size of any nation or US state to other land masses, by allowing you to move them around to anywhere else on the map."

(From curbed New York) "There are more than 1 million buildings in New York City, and many of those are clustered on the island of Manhattan, spanning architectural styles, hundreds of years, and all manner of types. And now, a nifty new tool, called All the Buildings in Manhattan, takes information about those myriad structures and puts it in one colorful data visualization."

The tool was created by Taylor Baldwin, a software engineer at BuzzFeed (“One thing I learned is that there is an unbelievable amount of data the city makes available.”)

(Note that I had difficulty getting it to work.)

Viz Palette is a colour picker tool to help with selecting a palette for data visualizations, including maps.
