This component shows the result of the OD Matrix computation for a given data set and a given zoning definition.
The controls on the top of the map allow you to create new computations of OD Matrixes. Two things need to chosen for a given computation:In the dropdown menu on the left you can see the names of the zones that are uploaded on the platform. Right now only the geojson "hood" is uploaded. It can be visualized by clicking the "Show" buttom. Upload geojson New areas can be uploaded to the platform by clicking the "New Areas" buttom. This action opens a new window where a new geojson can be pasted in the text area if you have it. To finish the upload of the geojson you can give a "Name" in the text line, below the large text area, and press buttom "Load".
Once the new areas are uploaded into the platform it will appear in the dropdown menu. The system has the funcionality to create a custom geojson by clicking in the "From Map" tab. This opens a new map where the user can click on the map to define a center where to create a series of circular concentric areas. The number of areas and the maximum size of the circle can be defined. By clicking "Generate GEOJSON" the platform creates the geojson into the text area. To complete the upload a name has to be provided and the "Load" buttom needs to be pressed.
To create a new OD Matrix computation you can select the areas from the dropdown meanu and press the "Create" buttom. This will take a couple of minutes and once the new computation is performed. The new computation appears in the dropdown menu on the right. The name of the computation will be "ringring"+<NAME OF THE ZONING>. Right now only the ringring hood computation is stored. The [0] besides the name shows the status of the computation, 0 means done, negative means it is in process. In order to have a new computation shown in this dropdown menu "reload" the webpage by clicking the buttom in your browser. Once you choose the computation in the dropdown meny click the Load buttom and it will update the drowndown meny for the zone indexes. You can choose the zone you want to specify as the origin (alternative destination by clicking in the tab buttom). and the zones will change their color corresponding the number of trips between zones.
