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.

OpenDroneMap is "an open source toolkit for processing aerial drone imagery. Typical drones use simple point-and-shoot cameras, so the images from drones, while from a different perspective, are similar to any pictures taken from point-and-shoot cameras, i.e. non-metric imagery. OpenDroneMap turns those simple images into three dimensional geographic data that can be used in combination with other geographic datasets."

In 2018 the Environment Agency announced that they plan to survey the whole of England at 1m resolution, completing the coverage by 2020. This will fill the gaps in coverage giving a complete lidar dataset for England, where currently 40% is either unsurveyed or surveyed at only 2m resolution.

Another example is the canton of Zurich which made its geodata available to the public free of charge from January 2018 onwards. The information should enable the development of business ideas. The authorities expect a lot of potential for the economy and society.

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).

New GIS mapping project is chronicling genealogical history through Waxahachie (Texas) Cemetery.“This is just for the benefit of our citizens so they can better search our cemetery. Genealogy is becoming a very popular hobby and a very popular thing for families to do,” Smith explained. “It will help in that hobby and help our citizens better learn our cemetery because our cemetery is large and kind of confusing if you are not familiar with how it is laid out.”

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."

This post from Rory Biggadike of webmapsolutions says "We are today seeing an explosion in the number and type of mapping platforms. In this post we will discuss the differences between these mapping platforms, and why you might choose one over the other."

( 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.)

The Map Room (Jonathan Crowe blogging about maps since 2003) has many interesting things about maps - for example this list of Map Books which have been published or are scheduled to be published in 2018.

Latitude-Cartagena, a cooperative society based in Lyon, France, is "much more than a cartographic communication agency. It's a living network of cartographers, consultants, designers and developers working together to improve your everyday life ... without you noticing."
