The tools in the Data toolset add TravelTime Data API layers to your map: Demographics, Places, Open spaces and Neighbourhood.
Data from H3 Cells- reads data for an existing layer of H3 cells, such as the output of an H3 tool.Data from Locations- takes a layer of points plus travel time settings, and works out each location's catchment itself: the resolution 9 H3 cells reachable from (or to) it, from the/h3/fastendpoint.
| Output Type | Output |
|---|---|
| Totals | One polygon per catchment, its cells merged, with the catchment's totals as fields |
| Per cell | One polygon per distinct cell, with that cell's own data as fields |
| Features | One point per place in the cells, or per public open space touching them, with its own details as fields. Places and Open spaces only. |
Outputs are styled: each Neighbourhood measure is added as its own layer, Places per cell is coloured by count, and Open spaces per cell shows green space or not.
| Description | Tool | |
|---|---|---|
| Input H3 Cells | The layer of H3 cells to read. Resolution 9 or coarser for Totals, the chosen Resolution for Per cell, and 9 for Features. | H3 Cells |
| Cell ID Field | The field holding each row's H3 cell ID (h3_id in an H3 tool's output) | H3 Cells |
| Catchment ID Field | Totals only: the field naming the catchment each cell belongs to (Index_id in an H3 tool's output). Left blank, the whole layer is totalled as one catchment. | H3 Cells |
| Locations | The point layer to fetch data around | Locations |
| ID | The field identifying each location in the output | Locations |
| Travel Mode | As the Core tools | Locations |
| Departing / Arriving | Whether the catchment is for journeys departing from the locations or arriving at them | Locations |
| Time Period | The typical time period journeys are calculated for | Locations |
| Travel time (in minutes) | The maximum journey time. Max 180 minutes, or 90 at Resolution 10. For Totals, the Data API takes at most 200,000 cells per location, so a long drive can pass it. | Locations |
| Output Type | Totals, Per cell or Features (see Output types) | Both |
| Resolution | Per cell only: the H3 resolution of the cells. Places 6 to 10, Open spaces 9 or 10 (at 10, green cover is left out). The other layers are resolution 9 only. | Both |
| Data Layer | Demographics, Places, Open spaces or Neighbourhood | Both |
| Place Group | Places only: the group of places, such as Food & Drink. Left blank, every place. | Both |
| Place Categories | Places only: the categories and sub-categories of the Place Group to include. A category covers every sub-category under it. Left blank, the whole group. | Both |
| Open Space Classes | Open spaces only: Green Spaces, Beaches, or both. Left blank, every public open space. | Both |
| Neighbourhood Measures | Neighbourhood only: noise, air quality, flood, crime, deprivation and/or broadband. Left blank, every measure. | Both |
| Output Layer | Where to save the output - must be in the project geodatabase | Both |
Data from Locations also has the optional Transportation options, Snapping and Remove Water Bodies, described on Common parameters.
