Frames dataset

The Frames data category provides information about frames (pictures tied to coordinates) captured by the CityLens mobile application.

Overview

Frames data

To get started:

  1. Go to the Main or Data tab.
  2. Select the All Frames category.
  3. Specify the Territory.
  4. Set the remaining filter parameters if necessary.

The data will be displayed on the map as centroid points: the centers of the object geometries. Text results are available in two variants:

  • Statistics: general statistics about the sample. Include:

    • Total count of frames
    • Count of checked and not checked frames
    • Total count of frames with correct and incorrect detection
    • Total count of frames with uncompleted detection

  • Results: list of captured frames. When selecting a frame from the list:

    • All information about the frame is displayed in the next tab.
    • You can see the frame location by clicking Show on map.

    You can modify the list to keep only selected frames in the dataset. Click Edit list, select the required frames, and click Apply.

To save this selection and customize its visualization (e.g., as a heatmap), click Create layer.

Filters

For the Frames category, the following filters are available:

  • Territories: country and city selection. You can select no more than 5 cities per country. There may also be restrictions depending on the prices. Required for selection.

  • Nearby: limiting the selection by territorial availability. Possible options:

    • Off: default value.
    • Radius: circle with a radius from 10 to 100000 m around a point on the map. The default value is 10000 m.
    • Path: area on the map that is accessible by car or on foot within 5 to 30 minutes. The default value is 15 min.

    To change the area, drag the center point to the necessary area of the map.

  • Type of frame: indicates if objects in the frame are detected.

  • Status of frame: status of checking the frame.

  • Detection categories: categories of urban environment that can be detected.

  • Detection types: urban environment objects that can be detected.

  • Date: when a frame was captured. You can set a time frame to limit the data selection.

  • Driver: enter a driver email to filter out frames captured by a particular driver.

To reset the filter, click the cross icon next to the filter name. To reset all filters, click Reset filters at the bottom of the page.
