Abstract

A geospatial decision management system (GDMS) can save the overall state of a user'"'"'s experience at one point in time within a GDMS session so that the user can restore the overall state at a later time, such as by restoring a geospatial browser view (e.g., camera settings for rending the map on the display screen, layer state information, map location) and restoring the states of one or more instances of geospatially-referenced tools that were active at the time of the state save. Upon restore, the browser and tools are initialized with their saved states so that the user is presented with the same functionality, data, and browser view that were displayed and accessible at the time of the state save. Saved states are transportable and can also be sequenced and animated to allow presentation of a slide show of individual GDMS views.
