Major changes:
- Access control of sensors
Security mechanisms have been deployed to protect data from unauthorized
access. Sensors can be specified as private, protected or public. Each
sensor has an owner and an associated group. Private sensors are
accessible only by their owners. Protected sensors are accessible by
their owners or other users in the associated group.
- Direct overlay of graphs
The previous version always converts graphs to tiles before overlaying
them onto the map. We now support direct overlay of graphs over 2D maps,
which reduces response time from tens of seconds to several seconds. By
default, graphs are directly overlaid on top of 2D maps. For users who
wish to overlay a graph over 3D maps, they can change visualization
output type to "tiles" to convert graphs to tiles, and then switch to 3D
mode as before.
- More interpolation algorithms
The previous version uses Simple Kriging as the interpolation algorithm
during contour map generation. We now support two new algorithms:
Ordinary Kriging (more accurate but slower) and Inverse Distance
Weighting (faster but less accurate). Ordinary Kriging is used by
default. Users can use "Management Visualization -> Settings ->
Interpolation Method" to change to another interpolation method.
Minor changes:
- Fix the following bug: graph tile layer disappears when switching to
Virtual Earth 3D
