Thanks for the notice about that tool. I have been keeping empty older-version gdbs around for the same purpose but I like the tool. But, I just made a 10.0 gdb and mosaic dataset from my 10.2 install and another 10.0 machine can't read the mosaic dataset. Should it or am I expecting the tool to do something it can't?

It's been a while since I used a raster catalog, but I think that would be pretty slow for the amount of data I want to mosaic. The pyramiding is not as efficient as it is with mosaic datasets, is it? Also, I'm probably going to run into the same version problems as with mosaic datasets. I am beginning to conclude that the best way is for me to always stay 2 versions behind the leading version and build 10.0 mosaics.

It seems like I am frequently having to repair mosaic datasets or have someone in my office tell me that can't read one because they have an older version of ArcMap. But without a server, how do I make these gigabits of raster data easily accessible in a tiled and pyramided way? What seems to me to be a solution would be if ArcMap could read a local cache of TMS tiles or even KML superoverlays but I have not learned how that might work yet. I am trying to build a tile package right now, but you have to load all of that raster data into a map, for crying out. I just want to point the tool to a folder of rasters and let it run. And I wouldn't be surprised if I run into the same version issues as with mosaic datasets. Any suggestions?

The pdf 'Converting US Topo GeoPDF Layers to GeoTIFF' which is linked from about 2/3 of the way down this page - http://gis.nwcg.gov/gstop_symbol.html - has suggestions for what you want to do.

Thanks Gregory, that helps a bit. It looks like app.map is available as a hook. At least, when I type in 'app' on the console pane while debugging chrome, I get 'map' as an auto-fill choice. Darn, I am close, my basemap gallery button is there and it opens when I click it, but no map icons are displayed

Thanks Mark, If it comes to that, that's good to know. I just don't know if I need to do that or if I can put a few lines into my html and make it work. I will poke around in those un-minified versions, but if someone has a workflow they could share, I would be grateful.

Has anyone successfully added an extra javascript widget, from the samples for example, to a story map? Like the swipe tool or a basemap gallery? In all of the samples at which I have looked, a 'map' variable is passed to the widget and I can usually see where in the code the map is created, through a createMap function, for instance. But I cannot figure out where the equivalent is happening in a story map template. There is no reference to 'createMap', no 'map' variable. I presume the creation is tucked away somewhere in the minimized js files. So, can I get a reference to it from my index.html? If you have done this, please let me know!

Thanks Rupert, For the record, I installed the NVDA screen reader and it did not read out the names and descriptions of photos. I am not familiar with screen readers nor how this one compares to others, so it might be tweakable, but with the default configuration it didn't work.

A reviewer of my tour map pointed out that there appears to be no alt text attribute for the images when the mouse is hovered over the image. That probably makes it non-compliant with Section 508 for the visually impaired. I don't have a screen reader myself, so I can't check what might get read out to the listener as they tab through the elements. Is there any chance that the name and/or description would substitute for alt text? Or can I enable that attribute somehow and include the text in the csv that I am using to create the points in my map? thanks

Oh, I see. Thanks for the clarification. For the sake of discussion, this is what I figured out. If I add this style element to the top of my index.html: <!DOCTYPE html> <html> <head> <style> h2 {width:800px;} </style> and then add a div to the headerDesktop element to hold a picture of my legend or whatever:  <div id="headerDesktop"> <div class="textArea"> <h1 class="title"></h1> <h2 class="subtitle"></h2>  <div id="legend" style="width:160px;vertical-align:top;background-color:#FFA500;float:right;index"> <img src="mapdata/scarp_thumb.jpg" width="160px" height="160px"/> </div>  </div> I end up with this (which I guess you'll have to click on to expand - it's not very large in my preview) [ATTACH=CONFIG]31849[/ATTACH] You can see that I have made room for the div by reducing the width of my subtitle and the picture is in the right place horizontally, but it's not aligned correctly vertically. You can only barely see a strip of it above the map frame. I cannot get the div to move up at all. I don't know if its in the wrong div or what. It's frustrating, because it looks so close. So, what I ended up doing, as you can also see in the screenshot, is encode the legend in the map subtitle with html tags as Rupert suggested, which is not too bad. For what is worth to anyone who stumbles on this, the subtitle variable in my index.html looks like this: subtitle: "Photos are categorized by content:<br><img src='GenericRed.png' height='13px'/> landslide****<img src='GenericPurple.png' height='13px'/> ground shaking****<img src='GenericBlue.png' height='13px'/> post-earthquake engineering<br>foo<br>foo",

Hi Liz, How did you get "a few base layers" into your tour map? and, Did you ever get a legend put into it? thanks, Evan

Ok, thank you!

I am working with a map template I downloaded and am accessing AGOL services that are not yet public, so I have to log in everytime I refresh the web map. Is there a place I can store my AGOL credentials to avoid this?

I have dug through the code in the full developer's download and found the various modules loaded during creation of the tour map template, but I still cannot figure out how to pass a reference to the Map class to the sample code for the swipe widget. In the sample, the creation of the map is right up front in the html, but in the story map template, it's nested away in the dependencies. Can I even get to the map object from the Core or MainView variables inside the OnLoad function?

‎02-11-2014

So, I am getting somewhere. Taking the code from https://developers.arcgis.com/javascript/jssamples/widget_swipe.html and jamming it into the index.html that comes with Storytelling-MapTour-2.2.1 https://github.com/Esri/map-tour-storytelling-template-js I have successfully gotten my swipe widget and basemaps to appear....behind the thumbnails of my images down in the image carousel. What appears to be happening is that I am creating two map containers and one is getting placed incorrectly. I can sort of follow from the swipe example how the map is created to which the swipe widget is attached. What I can't figure out from the tour map template is where the equivalent is being done, that is, where the map is being created and how to reference it again. The example uses 'arcgisUtils.createMap' which is nowhere in the template. It looks like it might be happening through the loading of "storymaps/maptour/core/MainView". Where can I read more about that? Any nudges are greatly appreciated,
