About this API

Tile API and Coverage API are the first widely available APIs that follow a new standard for Nearmap APIs

Should I be using this API?

If you have not used our APIs before then yes, this is the right Tile API for you to use. If you are already using the Nearmap TMS (Tile) API, you should consider switching to this version of the API. This version is more feature rich and will allow you to do more with Nearmap content, such as:

  • Control over tile upscaling
  • Ability to hide low resolution satellite background imagery
  • Ability to request JPG or PNG tiles
  • Ability to request relative dates (e.g. show imagery that is at least one year old)
  • Richer metadata
  • Explicit survey tile requests

Introduction

Nearmap provides access to its Vertical and Panorama Imagery via a Tile API using Google Maps Tile Coordinates, also known as Slippy Tilenames. They map into a pyramid of 256x256-pixel map tiles at multiple zoom levels. An application typically downloads a collection of adjacent tiles to cover a given region.

Only the Web Mercator projection is supported, as per the de-facto web mapping standard (EPSG:3857; also known as EPSG:3785 and EPSG:900913). Nearmap’s Web Map Service (WMS) is recommended for other projections.

There are two ways you can use this API to retrieve tiles:

You can use the Coverage API in conjunction with the Tile API to retrieve coverage (surveys):

Authentication

Access to Nearmap imagery is only available to authenticated subscribers. Tiles may be requested from Nearmap servers with an API Key. Please refer to the API Key Authentication guide for details on how to obtain and use an API Key.

Note: If you have been using the previous version of our Nearmap Tile API (TMS), your existing API key might not work with the new API. If this is the case, please create a new API key to utilise this API. Note that your existing applications will be affected if you delete and re-create your existing API Key.

Panorama Imagery

Nearmap Panorama imagery is an orthorectified mosaic of 45 degree imagery from each cardinal direction (North, South, East, West), intended for visualisation use only.

The intended use of the Tile API for Panorama imagery is integration of Panorama imagery in a third-party web application, also for visualisation only.

Because it is created by combining many images, metadata that is normally associated with oblique imagery (such as pose and calibration), is not available. All the metadata available for panorama imagery is described under Coverage API.

Availability

The Panorama imagery is only available to customers with a Nearmap Panorama or Nearmap Oblique product.

Integration of Panorama tiles into a mapping application is complex. You will need to have significant experience with coordinate system geometry and map projections, and experience developing non-trivial mapping applications with a mapping framework such as OpenLayers or Leaflet.

URL Requests

Nearmap's Tile API is designed to be accessed by an application in an automated fashion via URL requests. We recommend that you use a mapping framework designed to consume tiled maps, such as OpenLayersLeafletGoogle Maps JavaScript API, etc.

Rate Limit

Nearmap's Tile API has a rate limit, meaning that there is a restriction on the number of requests that can be made against an endpoint. 

Retrieve Tiles

This API retrieves vertical or panorama tiles for a specified location. Use this API to add a Nearmap basemap to your application, with optional date control.

API URL Format

https://api.nearmap.com/tiles/v3/{tileResourceType}/{z}/{x}/{y}.{format}?apikey={YOUR_API_KEY}

Read more about the API URL format.

Parameters

RequiredNameAPI / queryTypeDescription

tileResourceTypeAPIstring

The resource type for the requested tiles. The available values are:

  • Vert - for vertical imagery
  • North - for North panorama imagery
  • South - for South panorama imagery
  • East - for East panorama imagery
  • West - for West panorama imagery

Note: the tileResourceType values are case sensitive.

zAPIinteger

The zoom level. Uses the Google Maps Tile Coordinates.

Note: the maximum zoom level is available from the Coverage API.

xAPIintegerThe X tile coordinate (column). Uses the Google Maps Tile Coordinates.

yAPIintegerThe Y tile coordinate (row). Uses the Google Maps Tile Coordinates.

formatAPIstring

The format of the tile output.

The available values are:

  • jpg - always JPEG
  • png - always PNG
  • img - JPEG by default, PNG when the tile is partial

Note that imagery is stored on Nearmap's servers as JPEG, so switching to PNG does not result in improvement in quality, however it will increase the size of the response.

apikeyquerystringYour API key. See API Key Authentication for more information.

tertiaryquerystring

The tertiary map to return when a Nearmap tile is not found.

The available values are:

  • none (default) - no tertiary imagery in the background
  • satellite - use our current tertiary backdrop

Note: returned tiles will always be blended with tiles from another survey. Tertiary tiles will only be blended when tertiary parameter is not 'none'.

untilquerystring

The last day from which to retrieve the tiles (inclusive).

The two possible formats are:

  • For a specific date: YYYY-MM-DD, e.g. 2015-10-31 to retrieve imagery until this date.
  • For a relative date: xxY, xxM, or xxD, e.g. 5M to retrieve imagery until 5 months ago.

Notes:

  • If specified, and imagery at that location at that date exists, the request returns the imagery.
  • If specified, and imagery at that location at that date does not exist, the request returns imagery of the next available date before the specified date.
  • If neither since nor until are specified, the request returns the latest imagery.

Examples

These examples use a demo API key. Replace this API key with your own when using the Tile API.

The following example shows a typical URL request:

https://api.nearmap.com/tiles/v3/Vert/21/1855981/1265938.jpg?apikey=Yzc2MjEzMWUtY2Q4YS00NTM2LTgyMDgtMDljZjI2YTdhMTMz


The following example shows a URL request that specifies the dates for which to retrieve the imagery using the until optional parameter:

https://api.nearmap.com/tiles/v3/Vert/21/1855981/1265938.jpg?apikey=Yzc2MjEzMWUtY2Q4YS00NTM2LTgyMDgtMDljZjI2YTdhMTMz&until=2018-08-01

Responses

The possible HTTP response status codes to the URL request are:

CodeDescription
200OK. Tile image in JPEG or PNG format.
400

Bad Request. Returned when the request is invalid. This means either the format is wrong, or a value is out of range.

401

Unauthorized. Returned when the API key is invalid.

403

Forbidden. Returned when not allowed to access the requested location.

404Not Found. Returned when cannot find any tiles for the requested condition.
429
