Query (GPS)

URL:: https://<imageservice-url>/queryGPSInfo
Methods:: GET
Required Capability:: Image, Catalog
Version Introduced:: 11.2

Description

The queryGPSInfo operation queries generic camera information, camera GPS locations when taking an image, image center coordinates, and exterior orientation information of each source image inside the image collection.

Request parameters

Parameter	Details
`where`	A where clause for the query filter. Any legal SQL where clause operating on the fields in the raster catalog is allowed. Example Use dark colors for code blocksCopy `1 OBJECTID=4`
`objectIds`	The object IDs of the raster catalog to be queried. Syntax Use dark colors for code blocksCopy `1 objectIds=<objectId1>, <objectId2>` Example Use dark colors for code blocksCopy `1 objectIds=37, 462`
`time`	The time instant or the time extent to query. Use dark colors for code blocksCopy `1 2 3 4 5 6 7 Time instant Syntax: time=<timeInstant> Example: time=1199145600000 (1 Jan 2008 00:00:00 GMT) Time extent (For time extents, one of <startTime> or <endTime> could be 'null'). Syntax: time=<startTime>, <endTime> Example: time=1199145600000, 1230768000000 (1 Jan 2008 00:00:00 GMT to 1 Jan 2009 00:00:00 GMT) A null value specified for startTime or endTime will represent infinity for start or end time, respectively.`
`geometry`	The geometry to apply as the spatial filter. The structure of the geometry is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API. In addition to the JSON structures, for envelopes and points, you can specify the geometry with a comma-separated syntax. Syntax Use dark colors for code blocksCopy `1 2 3 4 5 6 7 8 //JSON structure geometryType=<geometryType>&geometry={geometry} //Envelope simple syntax geometryType=esriGeometryEnvelope&geometry=<xmin>,<ymin>,<xmax>,<ymax> //Point simple syntax geometryType=esriGeometryPoint&geometry=<x>,<y>` Examples Use dark colors for code blocksCopy `1 2 3 4 5 geometryType=esriGeometryEnvelope&geometry={xmin: -104, ymin: 35.6, xmax: -94.32, ymax: 41} geometryType=esriGeometryEnvelope&geometry=-104,35.6,-94.32,41 geometryType=esriGeometryPoint&geometry=-104,35.6`
`geometryType`	The type of geometry specified by the `geometry` parameter. The geometry type can be envelope, point, line, or polygon. The default geometry type is envelope. Values: `esriGeometryPoint` \| `esriGeometryMultipoint` \| `esriGeometryPolyline` \| `esriGeometryPolygon` \| `esriGeometryEnvelope`
`inSR`	The spatial reference of the input `geometry` . The spatial reference can be specified as either a well-known ID or as a spatial reference JSON object. If `inSR` is not specified, the `geometry` is assumed to be in the spatial reference of the service.
`spatialRel`	The spatial relationship to be applied to the input geometry while performing the query. The supported spatial relationships include intersects, contains, envelope intersects, within, and so on. The default spatial relationship is intersects (`esriSpatialRelIntersects` ). Values: `esriSpatialRelIntersects` \| `esriSpatialRelContains` \| `esriSpatialRelCrosses` \| `esriSpatialRelEnvelopeIntersects` \| `esriSpatialRelIndexIntersects` \| `esriSpatialRelOverlaps` \| `esriSpatialRelTouches` \| `esriSpatialRelWithin`
`f`	The response format. The default response format is `html` . Values: `html` \| `json` \| `pjson`

Example usage:

The following is a sample request URL for the queryGPSInfo operation that queries GPS info of images within an envelope geometry and intersect spatial relationship:
