Hosted Map Service Doesn't Draw

JamesOsundwa — Wed, 22 May 2013 16:29:16 GMT

I've published several tiled map services to a subscription account of ArcGIS Online. The maps and data are copied to AGOO without any errors and published successfully. However, when I try to view the map in either the ArcGIS.com viewer or the Javascript viewer, nothing draws.

Here is an example of one of the services: http://tiles.arcgis.com/tiles/8ZpVMShClf8U8dae/arcgis/rest/services/Coral_reef_locations/MapServer

Please advise.

You have set up 20 levels of detail for this tiled service. Did you intend to have that many? you will be generating potentially a large cache.
Did you actually build the tiles?
Did you publish this data from ArcGIS Desktop?

Thanks,

Mike

Hi Mike,

I published the maps in ArcGIS 10.1, and took the default cache size chosen by the system, as advised in an article I read. I'm now trying to update/change the cache size and getting an error that I've exceeded my credits; are the two related?

Note that a summary of the cache status of all my 6 maps says that 0.0% of the tiles are present, and the generation is not in progress or scheduled. This was also the case with my initial publishing, only that this time I'm unable to edit the services because of exceeded credits.

Thanks.
James.

Yes credits and caching are related in that it costs credits to create a cache. By attempting to cache all 20 levels, depending on the extent of your data, you could be creating millions of tiles. The cost for tile generation is 1 credit per 1000 tiles. So generating a million tiles would cost 1000 credits.

There is a Manage Tiles option on the item details page of the service. From here, you can selectively build tiles for the scales you need. The larger the scale, the more tiles will be created. The system will show you how many tiles will be required for each scale.

ArcGIS Online currently supports two types of hosted services: Tiled map services and feature services. Depending on how you intend to use your data and how much there is, you may consider creating a feature service instead of a tiled service. In ArcMap, during the publishing process, you would check the Feature Access capability and uncheck Tiled Mapping. Feature services have a different set of abilities, so it would be worthwhile to learn about it to make sure it suits your needs.

Thanks,

Mike

Hi,

I'm still having issues getting Some of my hosted services to draw. I'm not sure on what criteria or basis the previous onces drew, but now the ones I create are simply blank services. See example: http://tiles.arcgis.com/tiles/8ZpVMShClf8U8dae/arcgis/rest/services/Key_Coastal_Ecosystems/MapServer

I've limited caching levels to no more than 4 levels.

I can't figure out what I'm missing.

Thanks!
James.

That service shows up if you zoom in to the 14th scale level. There are tiles from the 14th scale level till the 10th scale, which are 1:9,244,648.868618 and 1:577,790.554289:

Jonathan,

Thanks for your reply! Now I see it, and problem resolved. Does this mean that tiles must always be created for/from level 0 and the desired ranges?
