Vector Data Re-alignment — make your data more versatile.
Adjusting your geographic data so it is more accurately placed will allow you to leverage the ever-growing set of publicly available data for analysis and visualization as well as more consistently link to the GPS located data from your field crews.
iFactor Consulting’s Vector Rubber Sheeting (VRS) module provides a simple, intuitive and effective means of re-aligning your data. Whether you choose to make alignment adjustments based on an updated landbase, orthophotos or web-maps VRS gives you the tools to make local or global adjustments, each minutely refinable as needed. Here’s an example of a re-alignment in action:
The selected road (solid red) needs to be aligned to the underlying land base (a background Bing Maps street view accessed with iFactor’s Web Maps Connector is used here). Ground control vectors (blue pins and arrows) digitized by the user control the predicted re-alignment (dashed red). The bounding polygon of the ground vectors defines the area of influence for the re-alignment. Once the re-alignment looks acceptable it can be applied to some or all of the geometries in a given area, even if they are in a different dataset. The VRS module provides a rich set of tools for managing the digitized control vectors, their display and analysis. The user digitized data can be saved to file for later use, refinement or for conglomeration with other control vectors defined by other users.
