Weather Data APIs

Iteris’ comprehensive weather data solutions combine the vast knowledge and experience of Iteris’ in-house meteorological team. ClearAg’s continuously-updating forecast system leverages the best available data for any location globally.

Weather Map Tile Overlay

last updated 11/7/18

This bundle provides access to various content in the form of image tiles suitable for use in interactive maps based on the Google Maps coordinate and tiling system. This service provides graphical rendering of a subset of the same gridded weather and soil content that powers the ClearAg weather and basic soil APIs. It is designed for display of recent, current, and forecast basic weather conditions, geostationary weather satellite imagery, and radar data in interactive maps typically seen in mobile and web based applications. Note that this is not a service that provides gridded digital data values suitable for use in algorithms.

Please note that API responses are currently only provided in English.

Iteris requires the use of https when working within the ClearAg APIs.

Additional API information, such as details on legend values and map layers, is available in the Appendix.

Available overlay layers include:

  • recent, current, and forecast basic weather conditions rendered from the global and high-resolution US grids

    • Air temperature (including 24-hour minimum/maximum)

    • relative humidity

    • Dew point temperature

    • Wind speed (including gusts and daily maximum)

    • Precipitation accumulation (liquid equivalent and snow accumulation)

    • Forecast probability of precipitation and onset time

  • Geostationary Meteorological Satellite Imagery (Infrared and Visible):

    • Global mosaic

    • United States (updates more frequently than global)

  • Regional Radar Products (US, S. Canada, W. Europe, Australia):

    • Radar Reflectivity

    • "Future Radar" Nowcast

    • Multi-Sensor Precipitation Analyses

    • Hail Analysis

Please note that the availability of various layers provided by this service are subject to external disruptions. It is the responsibility of consuming applications to handle situations where layers are not reported as being available by the Tile Layer Index Request.

Tile Layer Index Request - v1.0

The Tile Layer Index Request endpoint provides a summary of available layers grouped by display intervals. A display interval in this context refers to the time period for which given layers are valid for display.

URL Description

https://tiles.clearapis.com/v1.0/layer_index?app_id={string}&app_key={string}
&display_start={Epoch timestamp (seconds)}&display_range={integer}
&display_interval={integer}&layer_filter={string}

Request Parameters

Parameter Type Required Description

app_id

string

yes

API ID provided by Iteris.

app_key

string

yes

API key provided by Iteris.

display_start

Epoch timestamp (seconds)

no

The requested Epoch timestamp from which display intervals begin. The default is the beginning of the most recent 5-minute interval. If provided, this entry will be truncated to the most recent 5-minute interval. "Display_start" parameter requests are limited to 25 hours prior and 49 hours after the current Epoch time. Please refer to the Epoch/Unix Timestamp section of the Appendix for Iteris' definition of Epoch/Unix timestamp.

display_range

integer

no

The number of display intervals generated. The default is 1, with a minimum of 1 and a maximum of 24.

display_interval

integer

no

The length of each display interval, in seconds. The default setting is 3600. The minimum is 300 and the maximum is 3600.

layer_filter

string

no

Comma-delimited list of requested layers. By default, all available layers for a time period are returned.1

1 Some layers may be inaccessible. Please contact your Iteris representative about obtaining access to additional layers.

Response Object (JSON)

The response object contains a summary of layers available at each display interval grouped by geographical areas of coverage (bounding boxes). These geographical areas are referred to as "domains." Descriptions of key properties are provided below.

Field Description

display_time

Epoch timestamp for which the results are valid. Please refer to the Epoch/Unix Timestamp section of the Appendix for Iteris' definition of Epoch/Unix timestamp.

domain_extents

Bounding box describing coordinates for which a domain is relevant. Currently, coordinates are in latitude and longitude with lower-left and upper-right coordinate pairs provided.

valid_time

Epoch timestamp for which a layer is valid. Please refer to the Epoch/Unix Timestamp section of the Appendix for Iteris' definition of Epoch/Unix timestamp.

tile_url

URL component used with a tiling client to specify tile paths.

layer_type

File extension to be used when requesting tiles. Currently, only "png" is returned.

Available Layers

The following is a list of currently supported layers, as of the time of publication. To reduce the size of the index response, users may filter out unwanted layers by providing a comma-delimited list of desired layer names. Providing no list returns all available layers.

Please note that although all default layers can be returned, users may only be able to request tiles for layers in which the given account allows. Also note that some layers are not available for some domains.

Layer timing information is given with respect to the layer valid time provided in the response. For example, in the case of the precip_acc_next_24hr layer, the data are valid for the 24-hour period starting with the layer valid time.

Example Layer Request and Tile Request Code

py_ex.py
  import requests
  import ujson
  import shutil

  r = requests.get("https://tiles.clearapis.com/v1.0/layer_index?app_id={string}&app_key={string}\
  &display_start={Epoch timestamp (seconds)}&display_range={integer}&display_interval={integer}")

  # The code below selects the contig_us radar tile for the first display interval returned
  radarTile = data["display_intervals"][0]["layers"]["contigus"]["radar"]["tile_url"] + "0/0/0.png"

  tile = requests.get(radarTile, stream=True)

      with open({path}, 'wb') as f:

Appendix

Common HTTP response codes

The following are common HTTP response codes and their meanings. These are standard across all API services.

  • 200 OK - The request was successful.

  • 400 Bad Request - The request was invalid. An accompanying error message will be provided if available.

  • 401 Unauthorized - Authentication to the API has failed. Authentication credentials are missing or incorrect.

  • 403 Forbidden - You are trying to access a resource for which you do not have the appropriate privileges.

  • 404 Not found - The requested resource was not found. An accompanying error message will be provided if available.

  • 500 Internal Server Error - An internal server error has occurred while processing the request.

  • 502 Bad Gateway - The service is not reachable.

Null or Empty Values

In some cases values will be represented as "n/a." This indicates that the requested data is not available or is not applicable.

Epoch/Unix Timestamp

Iteris employs Epoch/Unix timestamps for some time-based parameters. Timestamps are defined as the number of seconds since 1970-01-01 00:00 Coordinated Universal Time (UTC).

Note that in daily endpoints, timestamps as URL arguments do not necessarily conform to this definition. In these endpoints, timestamps can be thought of as being relative to the local time zone. For example, a plant_date timestamp corresponding to 2016-05-01 00:00 UTC in the Corn Growth endpoint can be viewed as 2016-05-01 00:00 local time, and the endpoint returns data starting on that date.

Regional-based Account Access

Any data stored by the Account API in one region is not available in another. Each region will require a unique set of credentials. Please contact your account representative if interested in utilizing an additional region. When attempting to use the credentials from one region with the services in another, an 'account not found' error will be returned with HTTP status code 400. See example below:

<title>400 Bad Request</title>
<h1>Bad Request</h1>
<p>Account not found.</p>
