室内与新IMDF标准映射你的地点rd

After spending all of history mapping the outside world, focus is turning indoors.It’s about time.According to an NPA study, we typically spend 90% of our life inside—and given the size of some airports and malls, I’m sure we’ve all ended up in Narnia while walking circles at some point.

But indoor mapping is about more than enabling wayfinding.

With a user’s permission, navigation apps can request location information that can deliver insight on what’s happening in your venue.This means you canprovide live updates to patrons和gather metrics for business intelligence, e.g.identify where foot traffic is heaviest.Facilities maintenance, building operations, and emergency response all stand to benefit.

The challenge is that enabling indoor positioning is not so easy.

GPS is less accurate indoors.Floor plans must be made available.Building information models must be converted to compatible formats.

Large platform providers have been responding:

At the Esri UC in July, Esri demoed the室内的ArcGISapp for enabling smart buildings.
In January,在此取得Micelloas part of a push towards indoor mapping support.
Apple introduced new indoor positioning technology for iOS back in 2014, which is accurate to about 3-5 metres and can tell what floor you’re on.Now, they’ve开发出一种新的数据模型for positioning in iOS apps called IMDF.

With all of this technology emerging, indoor wayfinding has become more accessible than ever, and we can expect big strides in the months to come.Here at Safe Software, we’ve been working to make it easy for anyone tobuild indoor mapping datasets和 have prototypedaugmented reality wayfinding。Let’s look at how you can useFME和 IMDF to enable positioning for your venue* on iOS.

* For the purpose of this blog we’re calling it a venue, but this is a generic indoor mapping term that applies to any buildings and facilities like airports, malls, campuses, train stations, Death Stars, hospitals, hotels, and more.

What is IMDF?

IMDF (Indoor Mapping Data Format)is a standardized data model used to describe a venue.It can be rendered on any device and is the first step to enabling indoor positioning for iOS apps.Underneath, it’s a package of GeoJSON files that meet specific data model requirements.

Challenge: Meeting IMDF Requirements

Of course, Step 1 has its challenges.Manually converting your floor plan data to IMDF means ensuring it meets a precise set of standards outlined in the IMDF specification.Then, once you meet the requirements, you’ll have to do it all over again if your information model for any part of the venue changes.

IMDF规范

This is whereFMEcomes in.By building an FME workflow, you can automate translation to IMDF without manually validating all of these specifications.Pull existing datasets from wherever they are, convert to IMDF, and then send the data through FME’sIMDFValidatortransformer to ensure the file meets requirements.

The免费在线IMDF验证工具also lets you submit your IMDF file and see a report detailing where the data fails to meet IMDF standards.

Steps: Converting your Floor Plan to IMDF using FME

To create IMDF from existing floor plans and ancillary data, your FME Workspace will go like this:

阅读不管它是数据 - BIM，CAD外，GeoJSON，ArcGIS中，等等。请注意，您也可以从头开始设计使用的软件，如ESRI的ArcGIS的楼层平面图。
丰富和将其转换为满足IMDF规范。这涉及到地理参照，语义丰富，分类，模式映射，以及清洁的某种组合。
验证对通过该IMDFValidator发送它的IMDF规范。
写IMDF。从那里，你可以通过提交数据集苹果苹果地图连接。

Venues are always changing, so it’s important to keep your IMDF up to date by running your conversion workflow whenever the venue source data is updated.You can do this by running your FME workspace on demand, or by publishing it toFME服务器和 running it on a schedule or automatically (e.g.when new data is placed in a directory).You can also send reports or alerts if data fails to meet requirements.

Extracting from IMDF

Workflows that convert data in the other direction are also helpful: reading IMDF and transforming it for visualization and analysis in other systems.For example, output to 3D PDF or KML to visualize the venue in another environment, or convert it to ArcGIS Indoors for ongoing editing.
