Mapa deslizante com imagem

Question

Olá,

Estou tentando criar um mapa deslizante usando uma imagem antiga digitalizada da cidade sobre um mapa-base. Usando o 10.2.2, georreferenciei a imagem em relação a um mapa-base e a retifiquei como um TIFF. Em seguida, criei um pacote de mapas. É aí que estou travado. Li que não é possível adicionar pacotes de mapas a um mapa do AGOL. Então, como posso criar meu mapa deslizante se também não é possível importar uma imagem para o AGOL?

Acho que estou um pouco confuso sobre quais etapas devo seguir no ArcMap para desktop depois de georreferenciar a imagem. Preciso criar um shapefile a partir daí? Se sim, como faço isso?

Agradeço desde já.

@ Sephe: I was referring to the message in the Add Data window when trying to import data to AGOL.

@ Owen: Thanks for the reply. After building the tiles on the Desktop I was able to publish the layer in AGOL. This was only possible, I realized, after removing the basemap from the ArcMap table of contents. Before I removed it I couldn't get past the Analyze step because the basemap was causing an error.

But then I ran into more problems as you can see here. The georeferenced image isn't legible and a good 1/3 of it is cut off (a section that would be on the west side of the river). And when zoomed in part of the image goes away. Actually, after downloading the image from the primary source and adding it to ArcMap it lost some of its clarity. I don't even know if that can be avoided?

Thanks again for your help.

Oh thanks for that explanation Owen. I was a bit confused myself as to how that works in ArcGIS Online after I started looking further for the answer to Jared's question. The help files weren't super clear or easy to navigate.

Hi Jared,

You can upload map packages to ArcGIS Online like Sephe pointed out, but that just stores the map package file itself on the web so that that others can download the map package itself and use it in Desktop.

It sounds like you want to add the image in your map document to a web map and share it as part of a story map. In this case, you should publish the map document with your TIFF from ArcMap as a hosted tile service.  This help topic has more information on how to complete this process.

You can either build your tiles using ArcMap on your desktop or let ArcGIS Online do it for you. If you let ArcGIS Online build the tiles you may consume credits. The help topic I referenced has information on both workflows.

Once you have a tile service in ArcGIS Online you can add it to a web map and share that in the swipe story map app.

Hope this help!

(I'm going to move this thread to the ArcGIS Online space since the question itself relates to hosted services rather than story maps.)
