Image service/Raster search

DamienRobinson — Wed, 03 Dec 2014 12:00:31 GMT

Hi,

Has anyone been able to successfully configure an image service query using either the default search or eSearch widgets in Flex?

I am trying to set up a search that allows a user to type in the name of the raster (for example, the rasters could be named using a unique ref id). When the raster is found it zooms and displays only that raster, as there may be overlapping rasters.

I have tried publishing a raster catalog (MapServer) and a referenced mosaic dataset (ImageServer). I can't seem to integrate the referenced mosaic service at all with any search functionality (graphical or text). I can partially integrate the raster catalog service, in that I can do a graphical search (but not text search) and it will return the footprint, but not display the raster. Obviously if I put the layer on in the layerlist the raster comes through underneath, but this is useless for overlapping rasters.

Any help/guidance on successful implementation would be greatly appreciated!

Thanks,

Damien

Damien,

I have no experience with image services but I don't believe that either the search or the eSearch support querying images services.

Robert,

Thanks for replying! It seems to be a bit of a dark art serving rasters as services in comparison to geometry based map services! An image service does have a query function, though it doesn't seem to return imagery directly when used (hence why the footprint geometry is only visible when querying). When querying through the REST API, the object id of each raster links to additional child resources (Raster Image and Info). The Raster Image resource seems to be where the actual imagery is referenced from the data store.

I think i might have to put something custom together to perform this functionality.

Hi Damien,

I'm looking into trying to accomplish something similar, creating custom queries for imagery on the ArcGIS REST services directories and then displaying the available imagery. Have you had any success in your efforts and, is it possible to do what I'm trying to do?

Thanks,

Chuck

Hi Chuck,

I went down the JavaScript route to solve this using auto-complete as detailed in the blog post below.
