Using ArcMap to create layer packages with 3D point symbols!

OK, so the title is a bit misleading, but we have been hearing from a few of you in regards to getting layer packages to display with 3D points in ArcGIS Explorer, and there is a way to do this using ArcMap.  The quick answer is to use a Layer or Layer Package that already has the desired 3D layer properties. Simply, add a layer with 3D properties to ArcMap and reset the data source for the layer to your point feature data.  While you cannot set 3D properties for a layer in ArcMap, if the layer already has 3D properties, ArcMap does not remove them.

For those of you that know how to reset the data source on a layer in ArcMap, you are set… you just need a point layer that already has 3D properties.  I have made one that has the basic settings for 3D points that most people want and you can get it here. The 3D properties will work well for general visualization of points in 3D and 2D.  A full explanation of the details follows below…

The issue:  points from an ArcGIS Layer appear flat (draped) and are too big in ArcGIS Explorer 3D
For an example we will take a look at a default layer from ArcMap.  In this case I have added point features representing cities in the United States (orange points).  I also have a shaded relief basemap loaded in for reference.

 

If we create a layer package (see help for creating packages) out of this layer and open it in ArcGIS Explorer we will see the following:

 

In ArcGIS Explorer 2D, it looks pretty good.  The layer has 2D properties and ArcGIS Explorer displays it as it is seen in ArcMap.  If we switch to 3D in ArcGIS Explorer we see that the points are displayed in a larger size.

 If we zoom in on the map we also see that the points are too big and they are draped on the surface.

 

This occurs because the layer does not have good 3D properties for this ArcGIS Explorer use case.  Using the layer package referenced above this can be corrected. Open this layer from ArcGIS.com in ArcMap.


 
The layer package contains a single point, but that is not important – because we just want the 3D properties from the layer. You are using this layer as a template for your point data.

Right Click on the layer and open the layer’s properties…


 

 On the Source Tab click the ‘Set data source’ button and browse to your point data.

 

Click OK and see your data displayed with the template layers symbols.  Pictured here is the same cities point data used above.
 

If we create a layer package from this layer and open it in ArcGIS Explorer 3D, it looks like this:

 

The symbols have better sizing for this use case and they display in 3D.
In ArcMap we can adjust the layer properties further, changing the layer name, symbol, symbol renderer, turn on labels, set HTML popup etc…  While 3D marker symbols like those in the ArcGIS_Explorer style work well, you can also use ArcMap’s character marker symbols .  For example, I changed the layer name, chose the ‘Hospital’ symbol from the ESRI style and changed the size from 18 to 14.

In ArcMap it looks like this:

In ArcGIS Explorer 3D it looks like this:

 

If you have a 3D Analyst license you can use the layer as template in ArcGlobe.  Of course, you can also use ArcGlobe to adjust the layers 3D settings and do more advanced 3D display.

Add-in updates at ArcGIS Explorer Labs

We’ve recently updated several add-ins that you can find in the ArcGIS Explorer Labs group on ArcGIS Online. Here’s an overview of the recently updated add-ins.

Query Plus

Query Plus allows you to select features using shapes or notes, and a spatial filter. Draw a shape or select a note, then select an appropriate spatial filter, and a selection color. Click Select to return the selected features in a data grid. From the grid you can save the selected features as notes that contain the feature attributes. Also contains an Adjacency control that you can use to select an area feature and then return those features that are adjacent to it.

Select-O-Matic

Performs attribute selection on feature layers using operators and free text SQL, and allows you to save features as notes. Includes =, Like, >, >=, <, <=, Between, and free-text SQL query. The rows that meet the selection criteria appear in a data grid. You can save the selected features as notes whose popup content consists of the attributes associated with the feature.

Zillow

This new add-in nables home value and comparables search via Zillow. Enter a home location or click on the map to return a Zestimate.

Planning your DevSummit: Desktop

The Planning your DevSummit series is aimed at helping you make the most of your time at the 2010 Developer Summit. We’re really excited by the technical sessions, user presentations, demo theaters and seminars we’ve got lined up for you and there is certainly a lot to take in. Hopefully we can help make planning your days at the DevSummit that little bit easier.

The Technical Sessions

Desktop and Engine developers have a lot to look forward to with the release of ArcGIS 10, and there are plenty of sessions that cover the new functionality. This post covers those sessions to help you decide which ones to attend. There’s also a Presummit Seminar about Python that’s worth checking out.


Day 0: Presummit Seminar

Python plays a greater role at ArcGIS 10, with new and extended functionality. Getting Started with Python in ArcGIS (8:30am) introduces the basics and takes you through to creating your own tools, highlighting the new features at ArcGIS 10.

 


Day 1

Developing .NET Applications for ArcGIS Engine (1:00pm) explores new features of Engine development at ArcGIS 10, covering a number of new components and touching on licensing. Some ArcObjects and .NET experience is required.

New at ArcGIS 10, Desktop Add-ins will be of great interest to anyone who’s had to deploy customizations to ArcMap. The Introduction to ArcGIS Desktop Add-ins (2:45pm) session discusses the add-in programming model and framework, coding patterns, distribution and debugging and is a must-see if you’re extending ArcMap.

 


Day 2

For Java developers, ArcGIS 10 also introduces Java Add-ins and Extending ArcGIS Desktop and Engine with Java (10:30am) uses real-world examples to show you how to create custom feature renderers and geoprocessing tools in addition to Desktop Add-ins.

Enhancing Your Applications with ArcGIS Online (1:00pm) is not strictly on the Desktop track, but covers consuming ArcGIS Online services and content, showing how they can be used in ArcGIS applications. Useful if you want to learn more about how to make good use of ArcGIS Online in your applications.

Once you’ve written great Desktop and Engine applications, you still need to have a system to deploy and manage them. Deploying Desktop and Engine Applications in .NET (2:45pm) will go into detail on best practices for deployment and distribution of Desktop and Engine applications, licensing, version compatibility, service packs and building setup programs. This session requires some experience with .NET and ArcObjects.

Again not strictly Desktop track sessions but nonetheless of potential interest to Desktop developers:

Both promise to be interesting, and if you’re thinking of making the switch to Web-based applications using one of our Web APIs then Redesigning Desktop Applications for the Web (4:30pm) will probably make most sense.

 


Day 3

If you’re interested in learning more about extending ArcGIS Explorer (which has its own SDK), Implementing ArcGIS Explorer (8:30am) is worth attending. If you’re mostly visualizing data, ArcGIS Explorer may provide all the functionality you need.

At the same time is Developer-to-Developer: The ESRI Development Process (8:30am) which will be useful and of interest to any developer.

A three-part session Developer-to-Developer: ArcGIS 10 Desktop Development Topics (10:15am) goes over 3 important aspects of enhancement introduced at ArcGIS 10: Display Performance, Geocoding, and migrating VBA/VB6 applications to .NET (ArcGIS 10 is the last release to support VBA and VB6).

Previous desktop sessions (Developing .NET Applications for ArcGIS Engine on Day 1 at 1:00pm and Developing .NET Applications for ArcGIS Engine Day 2 at 1:00pm) will have discussed Desktop and Engine specific licensing topics, but ESRI Product Licensing (10:15am) is a Q&A oriented panel discussion so if you have specific questions left this is your chance to put them to our team.

 


More Details

You can download the complete Desktop sessions overview as a PDF document to print out and bring with you to the DevSummit as a convenient reference.

In the run-up to the DevSummit we’ll be posting more of these guides to help you pick out the sessions you’ll likely want to attend, and we’ll also be discussing the User Presentations. These are the guides you can look forward to:

If you’ve got suggestions for what you’d like to see in these guides, let us know.

Refining your ArcGIS Online search

02/02/10–Here’s a recent post on the ArcGIS Explorer blog about refining your ArcGIS Online search. It’s targeted at Explorer users but is applicable to anyone.

Refining your ArcGIS Online search for Explorer resources

ESRI shares many useful maps and layers on ArcGIS Online that are of interest to ArcGIS Explorer and other ESRI product users. The ArcGIS Explorer team has also shared maps and add-ins on ArcGIS Online, and many users are doing the same. How do you refine your search to more easily find what you’re looking for?

Keyword search

By default when you enter a keyword you’ll find all matches. Matches start with tags, but include matches in the description. This means all types of shared content by all authors that have made them searchable. So if we enter demographics:

we will find all content types that match the keyword that have been publicly contributed by all authors.

Search by owner

One way you may want to filter your search is by owner. All ESRI content has been authored by the user “esri.” If you’re looking for ESRI authored content you can add owner:esri to your search:

This search returns a variety of types, some specifically for use in ArcGIS Desktop or Web maps that can’t be used directly in ArcGIS Explorer.

Search for a specific type

But if you look underneath the search box, you’ll find you can qualify the results further by choosing a type:

By choosing layers, we’re choosing a type (layer packages or layer files) that can be used directly in ArcGIS Explorer.

The ArcGIS Explorer team has organized content and tools (add-ins) into a couple of groups specifically for Explorer users. You can search for all arcgis_explorer shared content using a search like shown below:

 

Or can search for groups instead of content:

There’s lots of other permutations – for more information on searching, visit the narrowing your search results ArcGIS Online Help topic.
