00:01Hello. In this video, we'll talk about creating map caches with ArcGIS for Server 10.1.

00:07Map caching is the process where we pre-render map service data...

00:12...as a collection of images or tiles that are stored on the server.

00:17These tiles are actually stored in a folder called a map cache.

00:21Map caches are used to support map services that contain basemap data.

00:27In other words, data that does not change frequently or remains static.

00:32At Server 10.1, we've improved the user experience for creating map caches.

00:37The user interfaces are easier and more intuitive, and you'll see that in this video.

00:43The first thing to be aware of is that we have a new Caching Tools geoprocessing service.

00:49This is automatically created when you set up and configure a Server 10.1 site.

00:54In addition, you define the tiling scheme before you publish a map service.

01:01In other words, the map cache tiling scheme is actually part of the map service definition.

01:06And finally, you can also view the progress of map cache creation.

01:13This is ArcGIS Server Manager, a web browser-based application that enables you...

01:19...to administer an ArcGIS for Server site.

01:22First, we'll log in to the application.

01:27And as you can see, it's a user-friendly interface that allows you to administer...

01:32...an ArcGIS for Server site. Under the Services section, under Manage Services...

01:38...we can show and list all the different services available.

01:42Currently, I have three different folders.

01:45If I go into the System folder, we can see three different geoprocessing services.

01:51And the one we're interested in is the Caching Tools Geoprocessing Service.

01:56As I mentioned earlier, this service automatically gets created...

02:01...when I set up and configure a Server 10.1 site.

02:04If I click on this link, I can view more information about this GP service.

02:10And what I would like to highlight is, under Pooling...

02:13...we can define the number of instances for this service.

02:17In other words, how much power I am going to dedicate on my machine...

02:21...to perform caching jobs.

02:23You can see here I have eight instances set. And as a general rule of thumb...

02:28...you want to assign the number of instances to this service equal to the number of...

02:34...cores on your machine because the Caching Tools geoprocessing service...

02:39...performs all the caching jobs for the entire server site.

02:44In earlier releases of ArcGIS Server, you would assign instances for map caching...

02:50...as a property of the map service that you were trying to cache.

02:54Let's go back to the system tools. And next, we'll go into ArcMap.

02:58We're looking at NapervilleBaseMap, which is a map document that contains a rich...

03:03...collection of data for the city of Naperville, Illinois.

03:06You can see in the Table of Contents that we have many different datasets...

03:11...at many different scales for railroads, streets, water bodies, and parcels.

03:18I can zoom in to different map scales, and as you can see, we have a rich collection...

03:23...of features, as well as labels, displayed at many different scales.

03:29And what I would like to do is publish this as a map service basemap with a map cache.

03:36As I mentioned earlier, we've changed the user experience at Server 10.1 for publishing...

03:41...and building map caches. In fact, it's now part of the ArcMap user interface.

03:47To publish a map service, I go to the File menu, I click Share As, and choose Service.

03:54This opens the Share as Service wizard.

03:57I want to publish a new map service, so I will click Next.

04:00Then, I have to specify the server site...

04:03...that I want to publish the map service to. In this case, my local server instance.

04:09And I will accept the default map service name of NapervilleBaseMap.

04:14I will publish the map service to a folder called Naperville, and when I click Continue...

04:20...this will display the Service Editor dialog.

04:25In this window, I can define many different properties of my map service.

04:30Next, I will analyze my map document.

04:33At 10.1, you must analyze your map documents before you publish them...

04:39...as a map service. This is now mandatory to ensure that you've optimized everything...

04:44...in your map document for the web. As you can see in my results, I have no errors...

04:50...so I will dismiss the results dialog and I will continue setting parameters...

04:55...for my map service. And what I would like to highlight is the Caching options.

04:59Now, to activate the Caching options, I click Using tiles from a cache.

05:05The first thing I can specify is the tiling scheme.

05:08And I can have it match the tiling scheme for ArcGIS Online.

05:11I can use an existing tiling scheme or define a custom tiling scheme.

05:16Under Levels of Detail, you can see that ArcMap has already auto-detected...

05:22...the ideal scales for this map cache based on the data in the map document.

05:26Now, I can change the map scale if I wanted to, and you'll notice we've made it...

05:30...very user-friendly by not only giving you a scale value, but also some corresponding...

05:35...sample graphics to help you visualize the map scale.

05:39I can calculate the cache size. And, at the bottom, I have the option to build...

05:45...the cache automatically when I publish my map service, or I could build the cache...

05:49...at a later date. In earlier releases of ArcGIS Server, you would have to...

05:53...build your map cache after the map service was already published.

05:59Under Advanced Settings, I can see all my different scales...

06:03...along with their estimated disk space, and various parameters...

06:07...such as the minimum and maximum cache size, location of the cache directory...

06:11...and the area of interest to cache.

06:13What I would like to highlight is the Tile Format, and we have several different options.

06:17If you have vector data, you should use PNG8, as long as you have less than 256 colors.

06:24If you have more than that, you should use PNG24.

06:27If you have labels, you should use PNG32 with your vector data.

06:32And finally, JPEG and MIXED are good for raster data.

06:35Now since my Naperville basemap has more than 256 colors, as well as labels...

06:41...I'm going to choose PNG32.

06:44Now, I will publish the map service, so I will click Publish.

06:48So it's analyzing my map document and generating that map service.

06:53And once the map service is created, it will start to build its map cache.

07:01As you can see, it's creating the service definition file...

07:04...that goes along with that map service.

07:13Now that the map service has been created, we can view the progress...

07:17...of the map cache creation, so I'll click OK. I will then open my Catalog side panel...

07:24...and display my connection to my ArcGIS Server instance.

07:29Under the Naperville folder, I can right-click that map service and choose...

07:34...View Cache Status. And it will display a message dialog that indicates the status.

07:43I can also view the map cache creation status inside ArcGIS Server Manager.

07:52And if I go into the Naperville folder, I will see the NapervilleBaseMap Map Service.

08:00And now, I can click these four squares to view its map cache creation status.

08:10I can click Show Details, and you can see how the different layers of my cache...

08:16...are being built. Now, in the interest of time for this video, I will cut ahead to when...

08:21...the map cache is completed.

08:26After the map cache is created, I can view its properties by clicking the...

08:31...NapervilleBaseMap link, and view the Map Service properties.

08:35Under the Caching section, I can see all the different parameters that I set...

08:39...inside ArcMap when I published the map service.

08:43If I click the Capabilities section, I could open up the REST endpoint URL...

08:48...of the map service. And again, I can view all the different cache layers.

08:52I will view the map service in the ArcGIS JavaScript API viewer, and you can see...

08:58...that the basemap is very responsive. I can zoom in, or I can zoom out...

09:04...and all my features and labels render very, very fast.

09:08For more information, I can look in the ArcGIS for Server 10.1 help.

09:13Under the Publishing services folder, under Caching services, there is lots of great...

09:18...information on map caching. Thank you very much for listening.
