Geocodering van Canadese locaties

VitalyLivshits

<\/HEAD>

We beginnen de geocodering functionaliteit in ArcGIS Maps for Power BI te gebruiken om Canadese Dissemination Areas (DAs) te geocoderen en vinden deze functie erg nuttig.<\/P>

<\/P>

Om wat achtergrond te geven, komen Canadese DA-versies overeen met federale censusjaren. De 2 meest recente jaren zijn 2011 en 2016. De meeste DA-identificaties bleven hetzelfde van 2011 tot 2016. Volgens onze ruwe telling werden er in 2016 31 DAs toegevoegd aan het gebied van Toronto.<\/P>

<\/P>

We hebben de DAs van het gebied Toronto uit 2011 uitgezet met ArcGIS Maps for Power BI en ze werden allemaal succesvol geocodeerd. Echter, bij het uitzetten van de DAs van het gebied Toronto uit 2016, konden alle 31 nieuwe DAs niet worden geocodeerd en kregen we de foutmelding "failed to locate 31 features" van ArcGIS Maps for Power BI.<\/P>

<\/P>

Vragen:<\/P>

<\/P>

1) Gebruikt de Esri geocoding service inderdaad de Canadese dataset van 2011 om DAs te geocoderen?<\/P>

2) Wordt dezelfde dataset ook gebruikt om alle andere Canadese locatie types te geocoderen, zoals CSDs?<\/P>

3) Uitgaande van #1, zijn er plannen om de geocoding dataset te upgraden naar data van 2016? Zo ja, wanneer?<\/P>

<\/P>

Bedankt!<\/P><\/BODY><\/HTML>

Hi Vitaly - to answer your questions:

Yes, our boundary data for Canada is based of the 2011 census.
Yes - all of our Canadian boundary data is of the same vintage.
We do plan to update to the 2016 boundaries. It's my understanding some of this data is still being released by Statistics Canada. After it's all been released, our data vendor will get us the information in early 2018, we will process it and tentatively plan to release it in 2018.

Hi Scott Ball,

To follow up on a related item, we often plot data sets that have a few locations which fail to geocode. For example, 10 out of 500 features may fail to geocode. In such scenarios, the Esri visualization shows the number of features that failed to geocode. However, we cannot find a way to find out the specific locations behind that aggregate.

Is there a way to extract an exception report that would list the locations that failed to geocode? If there there is currently no way to do so, can a mechanism please be added in a future release? This is very important for troubleshooting purposes.

Thanks!

ScottBall

Hey Vitaly - yes, that's been on our radar for a little while now. We would like to expose that information to the user to help you track down troublesome records and do data cleanup. I don't have a timeline for you but it is something we've discussed and want to do.

Hi Scott,

Is it possible to add Dissemination Blocks (DBs) to the location type dropdown for geocoding in Power BI?

Thanks!

SBall-esristaff‌, can you please provide feedback on this one? Thanks.

Hi SBall-esristaff,

I am just wondering if you have a more definitive timeline to share around #3. Our users are quite eagerly awaiting 2016 geocoding. My understanding is that Stats Can has already released all the relevant data.

Thanks!

ScottBall

Hey Vitaly - I don't have any more current information than what is in my initial response. Our vendor will provide the updated info to us in early 2018 and we will need to process and validate the data. We will have it in our services later in 2018.
