A pair of Open-Source software libraries intended to be used in conjunction with
existing web mapping applications to
visualize uncertainty and communicate the impact of positional error within
The client-side library is written to readily integrate with Google Maps and OpenLayers for the rapid development of uncertainty-aware web mapping applications.
Correlated Errors: GMaps (v2)
This example generates multiple Gaussian positional offsets for each point in a small dataset. Errors between points are spatially autocorrelated - they tend in the same direction and magnitude.
Routing: GMaps (v3)
OpenError realizations can be employed for error propagation to common web mapping analysis functions. Identify routing problems in Leicester, or choose any two locations worldwide!
Extends current GeoDjango Point and MultiPoint functionality to handle positional error.
