Jim and I will be presenting at this year's State of the Map US conference, which is being held April 12-13 in Washington, DC. State of the Map US is a conference all about OpenStreetMap and how people around the world are using the free, worldwide dataset.
This year, we'll give an update on two of the Park Service's projects: Park Tiles and Places, both which use OpenStreetMap data and infrastructure. Jim and I are set to co-present in the Government and Humanitarian Relief session on Sunday, April 13th at 4:00PM. Our talk is titled "Park Tiles: Customizing OpenStreetMap Cartography and Infrastructure."
You can access the conference schedule here to get more details on the wide variety of interesting talks from the OpenStreetMap community.
We hope to see you in DC!

I am happy to announce that a project our team has been pondering, fleshing out, and working on for close to a year is almost ready for release!
The NPMap Builder is a graphical interface that walks Park Service employees through the process of building a map and then deploying it to internal or public-facing nps.gov web sites. We will post more detailed information about the Builder soon, but for now I'll get to the point of this post.
We are looking for ~50 National Park Service employees, contractors, and partners to help us beta test the first version of the Builder. We've conducted some internal testing, but need more "eyes" to help us discover and squash bugs before releasing the tool to a wider audience.
If you are interested in becoming a beta tester, send an email to email@example.com with the name of your NPS Active Directory account (the name you use to log on to your computer) and a description of a map you want to create with the Builder. Two important notes:
- You must be a National Park Service employee, contractor, or partner to participate in this beta (please make sure you send your request from an nps.gov email address)
- Only apply if you have time, over the next month or so, to test and are willing to submit detailed feedback

And just like that our team has grown from three to five in less than two weeks. I'm excited to welcome our newest team member, Jim McAndrew!
Jim will be taking over the reins of Places of Interest, which will eventually integrate OpenStreetMap and crowdsourcing into the National Park Service's internal data workflows. His expertise and work will be a huge benefit to both Park Tiles and our larger enterprise GIS efforts.
Jim brings a tremendous amount of experience working with OpenStreetMap to the team. He has been an active member of the OpenStreetMap community since 2009, a board member of the US Chapter of OpenStreetMap for the last two years, and Vice President of the US Chapter for the last year.
Take a look at Jim's team page for more information about his background and interests. You can also find him online on Twitter, GitHub, or the talk-us-nps OpenStreetMap mailing list. Welcome, Jim!

We are excited to welcome our newest team member, Alicia Tyson!
Alicia joins the NPMap team as a data manager. Alicia loves data – particularly geospatial data. Her primary duty will be working hand-in-hand with our partners to massage data and build out databases and services that feed National Park Service apps.
Alicia recently received her Masters of Science degree from the University of Denver, where her research focused on GIS modeling of landslides and risk perception in Machu Piccu, Pueblo, Peru. She also interned in the Park Service's National GIS Office for the past year, gaining valuable experience in the realm of Enterprise GIS.
When asked about what she is looking forward to in regards to this new position, Alicia replied, “I just want to help protect, preserve, conserve and otherwise celebrate this beautiful natural world we find ourselves in. I look forward to learning from and with the NPMap team and exploring and pushing as many frontiers as we can!”
Take a look at Alicia's team page to find out more about her. Welcome, Alicia!

While the most visible projects we work on are visitor-facing, our team also provides design and development support for applications that target our more technical internal users. The Esri server suite (ArcGIS Server and ArcSDE) is a critical component of these applications, as most National Park Service employees use ArcGIS Desktop to create and maintain their GIS data. In this post, I'll explain how our internal map portal, InsideMaps, leverages ArcGIS Server to allow users to quickly visualize and edit their GIS data in a targeted, usable, and accessible web environment.
The new version of InsideMaps, v2, is under active development, and two launch partners are currently utilizing it: the Division of Fire and Aviation Management and Cape Hatteras National Seashore.
InsideMaps v2 is built, first and foremost, on top of ArcGIS Server map and feature services. It does, however, use the NPMap Library internally, so it also includes full support for a number of other layer types, including, but not limited to: CartoDB, GeoJSON, KML, and MapBox Hosting.
All InsideMaps applications have the same look-and-feel: The black NPS bar with the application name at the top and the legend and modules to the left-side of the screen. These applications can be built using any four of the base APIs that are supported by the NPMap library: Bing, Google, Leaflet, or Modest Maps. Because of this, it is possible to bring in base map services from a large number of sources, including Bing, Esri, Google, MapBox Hosting, MapQuest, and any other provider that uses either the Tile Map Service or XYZ format.
Although the NPMap library includes a number of modules and tools, InsideMaps v2 overrides most of these with interfaces built specifically for use by a more technical audience. These tools include advanced functionality like uploading Shapefiles and GPX files (coming soon), printing via templates, advanced query/reporting functionality, and edit forms that include full support for ArcGIS Server aliases, default values, field types/constraints, domains, subtypes, and relationships. The support for relationships even includes the ability to access feature classes and tables that are more than one "hop" away.
In addition, InsideMaps v2 supports bringing "live" data in from external systems like the Facility Management Software System, NPS Focus, and the NPS Data Store. This integration of services is where InsideMaps really shines.
In the data panel in the screen shot above, you can see a legend displaying two different ArcGIS Server services published and maintained by Cape Hatteras National Seashore. “Access Line” is a map service that displays the current beach access status of roads at the park. “CAHA Birds” is a feature service, running on top of an ArcSDE geodatabase, that displays bird data created by wildlife biologists and technicians working in the field. The InsideMaps application was built to both simplify the workflow for getting data into the system and make interacting with the data easier. This simplification is necessary for two reasons: 1) Most wildlife biologists/technicians don't have access to and aren't familiar with using ArcGIS Desktop, and 2) the ArcSDE geodatabase is highly-relational, and therefore unintuitive and difficult for non-technical employees to use.
By publishing the data as a feature service using ArcGIS Server 10.1, the InsideMaps app is able to wrap the service with an easy-to-use interface and allow users to insert, update, and delete spatial and tabular data. Simplified forms help users navigate the relationships - some of which are four "hops" away from a feature class.
About Those Forms
InsideMaps v2 is built using ExtJS 4. ExtJS is an app framework that makes it possible to quickly develop high-performing, usable, and accessible desktop-class applications for the web. The forms you see below allow the user to easily traverse the hierarchy of the database schema. They also, as mentioned above, support all of the features of an ArcGIS geodatabase, including aliases, default values, field types/constraints, domains, and subtypes.
When we start work on a new InsideMaps app, we prefer to simplify the database schema as much as possible up front, as this enhances the user experience and makes everyone's job easier. In some cases, however, this isn't an option. In the case of the Cape Hatteras Birds app, the database utilizes the National Park Service's Natural Resource Database Template. This template is a standard for collecting Natural Resource data, so we didn't have any flexibility in making changes to the schema. This added quite a bit of complexity to the app development, but we were able to hide some of this complexity by building targeted forms for the various workflows defeined and used by the wildlife biologists and technicians working in the field.
This edit functionality works in conjunction with a layer's edit form to streamline the overall edit process, and all of this works seamlessly behind-the-scenes with ArcGIS Server feature services, so it is fully integrated with Cape Hatteras' GIS operations. Feature services utilized by InsideMaps can also be brought into ArcGIS Desktop, where they behave like any other layer.
And Finally, Versioning
ArcSDE versioning has proven to be a valuable function for Park Service GIS programs. Both the Cape Hatteras and Wildland Fire geodatabases are maintained by multiple users. In the case of Wildland Fire specifically, park and regional users update spatial data for their area(s) of interest. New data edits are checked by a data manager at the national level and pushed up the default (vetted) version of the geodatabase. Each version that exists in the geodatabase has its own set of services (both map and feature) that the InsideMaps application uses, based on which perspective of the app is being used.
Although the work we do doesn't always overlap with "traditional" GIS, in the case of our internal apps it is imperative that we provide full support and integration with the Esri suite of tools, as they are the primary tools used by our GIS employees. Because of this, InsideMaps v2 is built with "Class A" support for ArcGIS Server. As we continue to develop v2 out, we will enhance and add new features that increase our integration with ArcGIS Server and make it easy to build simple yet full-featured apps for Park Service employees, contractors, and partners. This is our primary focus for InsideMaps, and we look forward to making the platform a good complement to ArcGIS Server and other Esri server products like ArcGIS Online.
