Designers
A controlled cartographic composition with editable type and layout.
Live data. Deliberate composition.
Hydrographic Poster Generator
Turn HydroRIVERS data into print-ready cartography. Select a geography, choose a visual protocol, and generate a poster from the underlying river network.
One geography, three treatments
The data stays fixed. The visual protocol changes.
Each example below was generated from the same Guyana river network using a current application palette.
Built for communication
Start from the visual outcome you need.
GIS practitioners
A reproducible render from a supported geography and hydrographic network.
Institutions
Print-ready visual communication with visible source and metadata controls.
Developers
A focused workflow built around structured settings, preview, and export.
From spatial data to finished artwork
A constrained workflow with a clear result.
01
Clip a boundary
Choose a supported geography. PostGIS clips the HydroRIVERS network to its exact boundary.
02
Classify the network
Density rules sort rivers into a restrained visual hierarchy, from primary channels to minor tributaries.
03
Compose the poster
Typography, legend, north arrow, scale, and source details are placed through a consistent poster protocol.
04
Render for use
Review the finished composition, then export it for print or continue working with the vector design asset.
