The OpenStreetCam plug-in has once again brought a new
feature to help its users. It now allows displaying and filtering aggregated
detections based on their confidence level. The confidence level represents a
measure of confidence of the validity of the detection or aggregated detection.
New aggregated detections display
Aggregated detections can now be displayed using
a confidence level based color code. This is an optional behavior that can be
turned on in the plug-in preference settings by selecting the following
If selected, each aggregated
detection will be displayed with a border of the corresponding color, according
to the legend table displayed under the check-box.
Map display based on confidence level:
If the checkbox is not selected,
all aggregated detections are displayed with a white border.
Confidence level filtering
With the introduction of the confidence level attribute, a
new form of filtering was added. Filter data now allows setting a value for
minimum and/or maximum confidence level. When set, only the aggregated detections
with the appropriate confidence level will be displayed.
feature has been added the OpenStreetCam plug-in that allows the visualization
of the OSM Elements corresponding to the selected detection or cluster. OSM
Elements are the basic components of OpenStreetMap’s conceptual data model of
the physical world.
How to use the new feature
step is to select a detection or a cluster. If the selected item has OSM Elements,
the Matched Data button from the
details panel will be enabled.
By pressing the button, the corresponding OSM element will be drawn in the OpenStreetCam layer and it will persist until selection changes or the item is deselected.

The Telenav OSM team has a new JOSM plugin for you: Geohash. This plug-in displays a layer on top of the JOSM map that contains the corresponding geohashes, up to zoom level 10. It also allows searching for a specific geohash and moves the map to the corresponding area.
Our team has been using this plugin internally and thought it may be useful for some of you as well.
This plug-in can be used by those who work in specific areas based on geohash units.
How to use the Geohash plug-in
The geohashes are automatically generated based on the user map view and zoom level. Increased zoom means increased depth level for geohashes.
To search for a geohash, use the Geohash plug-in dialog. Type or paste the geohash code in the text field and press the Search button. If the code is invalid, a message will be shown. Otherwise, the map view will be moved and zoomed over the selected geohash.
To clear generated geohashes, double click a geohash and all geohashes from his parent will be cleared. Also, right click on Geohash layer will show the option to ‘Clear geohashes’ that will leave only the depth one grid.
