How to use Geo Mapper 2D

Upload a CSV file with georeferenced data (latitude and longitude in separate columns)
Configure the visualisation using drop-down menus in the Control Panel on the left (toggle open/close by clicking the eye icon 👁️)
View the Legend in the right panel (toggle open/close by clicking the key icon 🗝️)
Choose from a selection of basemaps and overlays, as required
Customise spatial data visualisation using symbol configuration
Configure pop-ups including numerical and categorical data, images, charts
Animate symbols using time or sequence if data allows (including pulse animation)
Use Analysis Tools such as Filter and Buffer tools; generate Desire Lines
Use Measurement Tools e.g. distance, area, generate Survey Points; find georeferences
Use Drawing Tools including Point, Line, Polygon, Freehand — with export/import options for use in other apps
Use Bookmarks with configurable tabs to pre-plan presentations and manage cognitive load
Use Data Editor for instant corrections and/or additions and export as CSV
Use Lock in changes to update the visualisation so that it is cached
Save your work using export (HTML and GeoJSON files) and share with others including a 'View only' share option

How to use Geo Mapper 3D

Upload a CSV file with georeferenced data (latitude and longitude in separate columns)
Configure the visualisation using drop-down menus in the Control Panel on the left (toggle open/close by clicking the eye icon 👁️) to access Terrain, Basemap, Overlays and Analysis Tools
Explore the 3D globe using pan, zoom, rotate. It can take a while to learn the controls but it's worth the effort!
View the Legend in the right panel (toggle open/close by clicking the key icon 🗝️)
Choose from a selection of basemaps, terrain and overlays
Customise spatial data visualisation using symbol configuration
Configure pop-ups including numerical and categorical data, images, charts
In Analysis Tools, create Elevation Profiles by drawing simple transect lines. 🏔️ An Elevation Profile requires 3D terrain. To enable this, open the Control Panel → Terrain → select Cesium World Terrain or Cesium World Bathymetry
Animate symbols using time or sequence if data allows (including pulse animation)
Use Analysis Tools such as Filter and Buffer tools; generate Desire Lines
Use Measurement Tools e.g. distance, area, generate Survey Points; find georeferences
Use Drawing Tools — import and use drawings saved in other apps
Use Bookmarks with configurable tabs to pre-plan presentations and manage cognitive load
Use Data Editor for instant corrections and/or additions and export as CSV
Save your work using export (HTML and GeoJSON files) and share with others including a 'View only' share option

🗂️ Sample Data Sets

Download a CSV, then upload it to Geo Mapper to explore the features. You can edit the data, add columns, and change the visualisation settings.

📖 Guides

Why no detailed guides yet? Apps are under active development. Detailed written guides would quickly become out of date and cause confusion as features change. So for now, experiment by uploading a sample dataset or a similar dataset of your own and use the drop-down sections in Control Panel as appropriate for the data.

Guides will be added here once the feature set has stabilised.
