An important component of the rWaves Mapping Service, is allowing Users to view “Heat Maps” of their data. A “Heat Map” is a cartographic term that describes the visualization of the concentration of a certain component of the Users’ data uploaded into rWaves. Red, “Hot” areas represent the highest concentration of incidences of events logged in to the database file uploaded in to the rWaves map. All points of related occurrences are collected and used to generate the greater “Heat Map” of events, generating the map similar to the one below. As to be expected, red indicates the highest concentration geographically, while the progressively softer colors of the spectrum reflect a lower concentration of events.
A field in your dataset can be used to weight the heatmap in a manner other than the default method of using purely the density of points found in a geographic region. Other adjustments like radius and opacity can be changed using the slide bars in the Layer Tray.
rWaves also allows the User to create a “snapshot” of the map interface which is available for download and printing offline.
The lower right-hand corner of the rWaves map interface is where the Add Features tools are located.
Clicking on the orange plus symbol brings up four ways to add features to the map.
3. Create Shape allows the user to create a polygon, circle or rectangle, add a description of the area or event highlighted by the shape, and upload photos or a short video.
