I have come across another 3D modelling system - WRLD3D, which used to be called eeGeo.  I shall not be exploring this further for my own purposes, but it looks wonderful.  It is hard to keep up with developments!

Now re-branded as WRLD3D.

The Journal by DavidRM (TJ) is a fairly free format journalling system. Entries can either be linked to dates, or loose-leaf.

The following assumes that you have created a loose-leaf category (eg Directory) in The Journal (TJ) v7, with entries that are Roads, under which are subentries that are dwellings along that road. Each entry and subentry must be given a name and a reference (which should be a unique set of alphanumerics). The fact it is a reference (or id) is indicated by it either being enclosed in parentheses, or being preceded by #.

For example you could have (although consistent referencing would be better):
  • Albany Road #R1
    • 1 (24)
    • Owl House (21)
  • Beach Road #R3
    • 24a (SE2)
    • 24b (SE3)

Within M4OPS the dwellings will be called Entry (ref) - subentry (ref), or subentry, entry. The reason for the reference is just to make (sub)entries unique and clearly identified. Thus eg Owl House will be called "Albany Road #R1 - Owl House (21)", or "Owl House, Albany Road".

Within The Journal (TJ) each entry has a page where you can enter text, tables, images etc. The purpose of the process below is to make these pages available to M4OPS so you can see them when you hover over, or click on, a feature in M4OPS. It is best if you do not format your TJ pages too much as at the moment this can confuse M4OPS.

[Note that when we talk about HTML files below we include their associated image (jpeg) files.]

Broadly speaking the stages of the process are:
  • Create HTML files from The Journal (TJ)
  • Upload the HTML files to M4OPS
  • Create the list of features for M4OPS
  • Add the All Features layer
  • Upload and compile

Create HTML files from The Journal (TJ):
  • Create a folder for the HTML export to go into
  • Open The Journal (TJ)
  • File/Export/Export Entries to Document
  • Either:
    • Select the relevant category (eg Directory), and deselect the entries not wanted (eg templates), or
    • Select just the entries wanted from within the relevant category (eg Directory)
    • [Note that, if partially selected, to deselect the whole category you need to fully select it first]
  • Under Export Type
    • Select HTML
    • Make sure that "Export as a Web page with category & entry index" is not selected
    • Make sure that "Save CSS information in .html file" is not selected
    • [Note that these options, and those following, should carry over from the previous export]
  • Under Export Options
    • Select Create a File for each exported Entry
    • Make sure that "Include Category Name Header in export" is selected
    • Make sure that "Include Entry Date/Name Header in export" is selected
  • Under File Names
    • Enter the Category File Name as %c (eg “Directory”)
    • Enter the Entry File Name as %e (eg “Albany Road (R1)”)
    • Make sure that Include "Full Path" in Loose-Leaf Entry Names is selected (eg Albany Road (R1) - Owl House (21)
    • Enter the Export Path separator as  ‑  (ie blank, hyphen, blank)
  • Click on Export
  • When asked, browse to open the folder in which to put all the files (html and related images)
  • Click on Save
  • When it says Entries Exported, click on OK
  • You can now close The Journal (TJ)
[Note that at this point you can check individual exported HTML files by just opening them, but if their reference includes an # their associated image (jpeg) files will not appear. This is solved online by the processes below.]

Upload the HTML files to M4OPS
  • Use an FTP program (eg FileZilla)
  • On the server open the relevant OPS/HTML folder, and delete any files no longer needed
  • On your PC select all the files in the folder to which you exported from The Journal (TJ)
  • Upload all these (HTML and jpeg) files to the relevant OPS/HTML folder
  • [You can check individual uploaded HTML files within a browser, but again if their reference includes an # their associated image (jpeg) files will not appear.]

Create the list of features for M4OPS:
  • Open Karen’s Directory printer (can be downloaded free from here), and list files:
    • Select the Save to Disk tab
    • Select the folder specified above
    • Save Options: File info only
    • Ensure all other options (Search Sub-Folders etc) are not ticked
    • File info: ensure just File Name is ticked
    • File Filter: select Common HTML/Web files
    • Ensure the two Formatting options are ticked (Omit COMMENT lines, Omit FILE FOLDER and TOTAL Line ids)
    • Click on Save to Disk
    • When asked, browse to choose the folder in which to put the Directory Print (DirPrnInfo.txt)
    • You can now close Karen’s Directory printer
  • Open https://regexr.com/ - an online tool to learn, build, & test Regular Expressions
    • Copy the contents of DirPrnInfo.txt, and paste them into the Text area
    • Copy the following string and paste into the Expression area
      • (.+) - {0,}(.+)( [\(\#])(\w+)(\)*)(?:\.html)
      • [making sure the (default) /g flag is set]
      • [The groups are thus 1)Road 2)Dwelling 3)Prefix 4)Ref 5)Postfix]
    • In the Tools area, click on List
    • Copy the following string and paste into the List expression area
      • $4;$2, $1$3$4$5;;;;$&;$1 - $2;$2, $1;;;;\n
    • Copy the resulting list and paste it into a blank Features.csv text file
    • Insert at the top of this file:
      • featureid;shorttext;datestart;dateend;image;html;textforsort;fl_col1;Lon(X);Lat(Y);GeomType;GeomCoords (with a new line)
    • Open DirPrnInfo.txt in Notepad++ and replace the following:
      • (.+) - {0,}(.+)( [\(\#])(\w+)(\)*)(?:\.html)\r\n
      • by null
      • [making sure the Search Mode is set to Regular Expression]
      • [This removes all the lines we have just processed and leaves others]
    • The lines that remain are either Roads with valid references, or entries with invalid references
    • Copy any lines in DirPrnInfo.txt that are Roads with valid references into the RegExr Text area
    • Copy the following string and paste into the Expression area
      • (.+)( [\(\#])(\w+)(\)*)(?:\.html)
      • [again making sure the (default) /g flag is set]
      • [The groups are thus 1)Road 2)Prefix 3)Ref 4)Postfix]
    • In the Tools area, click on List
    • Copy the following string and paste into the List expression area
      • $3;$1$2$3$4;;;;$&;$1;$1;;;;\n
    • Copy the resulting list and paste append it to the Features.csv text file
    • Save Features.csv

Add the All Features layer to the LayerDefs_Feature.csv file:
  • Whereas the above process must be done whenever the Journal entries change, this is just done once
  • Where the fieldnames are
    layertype;category;title;csvname;candownload;url;attribution;mapkey;minx;miny;maxx;maxy;shorttext;description;fl_Ncols;flhead_col1;layerdescription
  • the All Features layer entry is
    Vector;Local;All Features;AllFeatures;TRUE;AllFeatures.geojson;#PDC#;;;;;;;;1;;These are all the features as we have recorded them.

Upload and compile:

Sources of Maps and Geographic Datasets / AWS public datasets
« on: 4 December 2017, 10:27:32 »
AWS (Amazon Web Services ) hosts a variety of public datasets that anyone can access for free, called AWS public datasets. Several of these datasets are Geospatial, including OSM for which details are given here.

The Genealogist announced in 2017 that they will be publishing the 1910 Valuation of England (or "Lloyd George Domesday Survey") which reveals who was living where and who the owner of the property.

In his introductory article, Nick Thorne explores the unique online collection of Land Tax records and maps revealing Edwardian occupiers and owners of property - as well as some long lost streets!

In the article We mapped it so you don’t have to the University of Georgia (UGA) Libraries’ Willson Center Digital Humanities Lab compare several mapping systems that students and faculty might consider using:
  • Google Fusion Tables
  • Carto
  • ArcGIS
  • Neatline (and Omeka)
None seem very relevant to One-Place Studies.

Mapping Technologies we can probably ignore / GPS Visualizer
« on: 4 December 2017, 07:42:13 »
GPS Visualizer is "an online utility that creates maps and profiles from geographic data. It is free and easy to use, yet powerful and extremely customizable. Input can be in the form of GPS data (tracks and waypoints), driving routes, street addresses, or simple coordinates. Use it to see where you've been, plan where you're going, or quickly visualize geographic data (scientific observations, events, business locations, customers, real estate, geotagged photos, etc.)."

One of the places it is used is the Walking Englishman site mentioned here.

Other Mapping things / The Greenwich Meridian Trail
« on: 4 December 2017, 07:38:08 »
The Greenwich Meridian Trail is 439 km (273 miles) and follows the line of the Prime Meridian as closely as practical, using public rights of way. The route does not slavishly stick to The Meridian, but has been chosen to give an interesting, varied and memorable walk. These two websites Walking Englishman and LDWA (Long Distance Walkers Association) include an interactive map.

The LDWA map uses maps from John Thorne, which are specifically designed for walkers in Britain.

The Isaac Johnson Map Collection (HD11/475) at Suffolk Record Office has surveys and maps of estates in almost every parish in East Suffolk as well as many in West Suffolk.  Isaac Johnson (1754-1835) was a Woodbridge based Topographical Artist and Land Surveyor.

Some have been digitised.
