A field trip that starts with a map
Give a lesson a sense of place. This Washington, DC example pairs museum, library and landmark icons with short observation tasks. Teachers can adapt the locations, add their own prompts and export a classroom handout or share a reference map without publishing student information.
Start an editable copy with this data and your current map styling.
What to look at
- Recognizable place icons make destinations easy to discuss.
- Each popup contains a prompt a teacher can replace with their own lesson activity.
- Export a PNG handout or publish a reference link; keep student information out of public maps.
Source columns
These fields describe the example data. CSV and Excel use first-row headers; GIS formats store geometry and feature properties. Required geometry depends on the map type.
| Column | Type | Example |
|---|---|---|
| name | text | Natural History Museum |
| notes | text | Observation task · compare two habitats |
Rebuild it with your own data
- 1
Get your GeoJSON file ready
The example fields are name, notes. For CSV or Excel, put headers in the first row. GIS files carry geometry and feature properties. Prepare any grid, catchment or route geometry before import.
- 2
Drop it into the studio
MapCrafter detects the geometry, counts the features, and shows the layers it found.
- 3
Style the imported layer
Pick which column drives colour, and which drives size or width where relevant.
- 4
Pick a basemap theme
Positron is used here. 15 other basemaps are available, including official OpenFreeMap styles. Switch using Layers & basemap.
- 5
Share or export
Publish a link, embed the map, or export a PNG at print resolution.
Questions about this example
- What file format does this learning locations use?
- This example illustrates GeoJSON data. The live preview uses GeoJSON geometry. MapCrafter reads GeoJSON directly, along with Excel, CSV, KML, KMZ, GPX, GeoJSON, TopoJSON and zipped Shapefile. No conversion step and no desktop software.
- What columns does the source data need?
- The file used here has 2 columns: name, notes. For tabular imports, supply coordinate columns, WKT or GeoJSON geometry, or address columns for an explicit geocoding step. Polygon and line files carry their geometry separately from these attributes.
- Can I use my own data with this map type?
- Yes. Open the studio, drop in your file, and MapCrafter detects the geometry and applies a starting style. Then style the layer and choose which property drives colour, size or width. The studio can render a point heatmap, but grids, routes and catchment polygons must be prepared before import.
- Can I export or share the finished map?
- Each map can be published to a short share link, embedded in another page with an iframe, or exported as a print-resolution PNG. The cleaned-up geometry can also be exported as GeoJSON. All of that is available on the free tier.
- Where does the data in this example come from?
- Illustrative teaching activity using approximate public landmark coordinates in Washington, DC. Tasks and the meeting point are examples, not an approved school itinerary. No student names, home addresses or personal information are included. Confirm access, supervision and arrangements separately.
