uMap: Analysing and Visualising spatial historical data

Lesson in a nutshell:

1. Embedding historical maps as custom overlays in uMap
2. Enriching a dataset wich spatial information (coordinates and polygons) in GeoJson.io
3. Which kind of layers or visualizations do I need?
4. Uploading spatial data into and Creating layers in uMap
5. Editing layers (shape, color, pop-ups, user interface, etc.) in uMap
6. Adding text and images to popups
7. Setting up a slide show
8. Saving maps as images
9. Saving spatial data for future use in other GIS tools

Step 1: Embedding historical maps as custom overlay in uMap

• Log in to uMap
• Click on "Create a Map" (top right)
• Name the map (top left)
• Zoom to the desired geographic area
• Click on "Settings" - "Custom Overlay"
• Enter the (MapWarper) link of the historical map
• Verify if the georeferenced map aligns with the visualization goals.

Step 2: Enriching a dataset wich spatial information (coordinates and polygons) in GeoJson.io

• We work on http://geojson.io (No registration required)
• Create a table with numbered IDs for the needed locations
• Zoom to the desired geographic area
• If necessary, integrate a historical map (Tab "Meta – Add tile raster layer")
• Define points, lines, or polygons in order (Numbered ID: crucial!!!)
• Save the coordinate file (Tab "Save" – CSV or GeoJson)
• (depending on geometry: points: .csv, lines or polygons: .geojson)
• Upload the GeoJson files directly to uMap (as layers)
